-## v0.37.0
+*October 19, 2018*
 
 Special thanks to external contributors on this release:
+@bradyjoestar, @connorwstein, @goolAdapter, @HaoyangLiu,
+@james-ray, @overbool, @phymbert, @Slamper, @Uzair1995
+
+This release is primarily about adding Version fields to various data structures,
+optimizing consensus messages for signing and verification in
+restricted environments (like HSMs and the Ethereum Virtual Machine), and
+aligning the consensus code with the [specification](https://arxiv.org/abs/1807.04938).
+It also includes our first take at a generalized merkle proof system.
+
+See the [UPGRADING.md](UPGRADING.md#v0.26.0) for details on upgrading to the new
+version.
 
 Friendly reminder, we have a [bug bounty program](https://hackerone.com/tendermint).
 
-### BREAKING CHANGES
+BREAKING CHANGES:
 
-- CLI/RPC/Config
-    - [config] \#9259 Rename the fastsync section and the fast_sync key blocksync and block_sync respectively
+* CLI/RPC/Config
+  * [config] [\#2232](https://github.com/tendermint/tendermint/issues/2232) timeouts as time.Duration, not ints
+  * [config] [\#2505](https://github.com/tendermint/tendermint/issues/2505) Remove Mempool.RecheckEmpty (it was effectively useless anyways)
+  * [config] [\#2490](https://github.com/tendermint/tendermint/issues/2490) `mempool.wal` is disabled by default
+  * [privval] [\#2459](https://github.com/tendermint/tendermint/issues/2459) Split `SocketPVMsg`s implementations into Request and Response, where the Response may contain a error message (returned by the remote signer)
+  * [state] [\#2644](https://github.com/tendermint/tendermint/issues/2644) Add Version field to State, breaking the format of State as
+    encoded on disk.
+  * [rpc] [\#2298](https://github.com/tendermint/tendermint/issues/2298) `/abci_query` takes `prove` argument instead of `trusted` and switches the default
+    behaviour to `prove=false`
+  * [rpc] [\#2654](https://github.com/tendermint/tendermint/issues/2654) Remove all `node_info.other.*_version` fields in `/status` and
+    `/net_info`
 
-- Apps
-    - [abci/counter] \#6684 Delete counter example app
-    - [abci] \#5783 Make length delimiter encoding consistent (`uint64`) between ABCI and P2P wire-level protocols
-    - [abci] \#9145 Removes unused Response/Request `SetOption` from ABCI (@samricotta)
-    - [abci/params] \#9287 Deduplicate `ConsensusParams` and `BlockParams` so only `types` proto definitions are used (@cmwaters)
-        - Remove `TimeIotaMs` and use a hard-coded 1 millisecond value to ensure monotonically increasing block times.
-        - Rename `AppVersion` to `App` so as to not stutter.
-    - [types] \#9287 Reduce the use of protobuf types in core logic. (@cmwaters)
-        - `ConsensusParams`, `BlockParams`, `ValidatorParams`, `EvidenceParams`, `VersionParams` have become native types.
-      They still utilize protobuf when being sent over the wire or written to disk.
-        - Moved `ValidateConsensusParams` inside (now native type) `ConsensusParams`, and renamed it to `ValidateBasic`.
-    - [abci] \#9301 New ABCI methods `PrepareProposal` and `ProcessProposal` which give the app control over transactions proposed and allows for verification of proposed blocks.
-    - [abci] \#8216 Renamed `EvidenceType` to `MisbehaviorType` and `Evidence` to `Misbehavior` as a more accurate label of their contents. (@williambanfield, @sergio-mena)
-    - [abci] \#9122 Renamed `LastCommitInfo` to `CommitInfo` in preparation for vote extensions. (@cmwaters)
-    - [abci] \#8656, \#8901 Added cli commands for `PrepareProposal` and `ProcessProposal`. (@jmalicevic, @hvanz)
-    - [abci] \#6403 Change the `key` and `value` fields from `[]byte` to `string` in the `EventAttribute` type. (@alexanderbez)
+* Apps
+  * [abci] [\#2298](https://github.com/tendermint/tendermint/issues/2298) ResponseQuery.Proof is now a structured merkle.Proof, not just
+    arbitrary bytes

 # Contributing
 
-Thank you for your interest in contributing to Tendermint! Before
-contributing, it may be helpful to understand the goal of the project. The goal
-of Tendermint is to develop a BFT consensus engine robust enough to
-support permissionless value-carrying networks. While all contributions are
-welcome, contributors should bear this goal in mind in deciding if they should
-target the main Tendermint project or a potential fork. When targeting the
-main Tendermint project, the following process leads to the best chance of
-landing changes in `main`.
+Thank you for considering making contributions to Tendermint and related repositories! Start by taking a look at the [coding repo](https://github.com/tendermint/coding) for overall information on repository workflow and standards.
 
-All work on the code base should be motivated by a [Github
-Issue](https://github.com/tendermint/tendermint/issues).
-[Search](https://github.com/tendermint/tendermint/issues?q=is%3Aopen+is%3Aissue+label%3A%22help+wanted%22)
-is a good place to start when looking for places to contribute. If you
-would like to work on an issue which already exists, please indicate so
-by leaving a comment.
+Please follow standard github best practices: fork the repo, branch from the tip of develop, make some commits, and submit a pull request to develop. See the [open issues](https://github.com/tendermint/tendermint/issues) for things we need help with!
 
-All new contributions should start with a [Github
-Issue](https://github.com/tendermint/tendermint/issues/new/choose). The
-issue helps capture the problem you're trying to solve and allows for
-early feedback. Once the issue is created the process can proceed in different
-directions depending on how well defined the problem and potential
-solution are. If the change is simple and well understood, maintainers
-will indicate their support with a heartfelt emoji.
-
-If the issue would benefit from thorough discussion, maintainers may
-request that you create a [Request For
-Comment](https://github.com/tendermint/tendermint/tree/main/docs/rfc)
-in the Tendermint spec repo. Discussion
-at the RFC stage will build collective understanding of the dimensions
-of the problems and help structure conversations around trade-offs.
-
-When the problem is well understood but the solution leads to large structural
-changes to the code base, these changes should be proposed in the form of an
-[Architectural Decision Record (ADR)](./docs/architecture/). The ADR will help
-build consensus on an overall strategy to ensure the code base maintains
-coherence in the larger context. If you are not comfortable with writing an
-ADR, you can open a less-formal issue and the maintainers will help you turn it
-into an ADR.
-
-> How to pick a number for the ADR?
-
-Find the largest existing ADR number and bump it by 1.
-
-When the problem as well as proposed solution are well understood,
-changes should start with a [draft
-pull request](https://github.blog/2019-02-14-introducing-draft-pull-requests/)
-against `main`. The draft signals that work is underway. When the work
-is ready for feedback, hitting "Ready for Review" will signal to the
-maintainers to take a look.
-
-![Contributing flow](./docs/imgs/contributing.png)
-
-Each stage of the process is aimed at creating feedback cycles which align contributors and maintainers to make sure:
-
-- Contributors don’t waste their time implementing/proposing features which won’t land in `main`.
-- Maintainers have the necessary context in order to support and review contributions.
+Please make sure to use `gofmt` before every commit - the easiest way to do this is have your editor run it for you upon saving a file.
 
 ## Forking
 
 Please note that Go requires code to live under absolute paths, which complicates forking.
 While my fork lives at `https://github.com/ebuchman/tendermint`,
-the code should never exist at `$GOPATH/src/github.com/ebuchman/tendermint`.
+the code should never exist at  `$GOPATH/src/github.com/ebuchman/tendermint`.
 Instead, we use `git remote` to add the fork as a new remote for the original repo,
-`$GOPATH/src/github.com/tendermint/tendermint`, and do all the work there.
+`$GOPATH/src/github.com/tendermint/tendermint `, and do all the work there.
 
 For instance, to create a fork and work on a branch of it, I would:
 
-- Create the fork on GitHub, using the fork button.
-- Go to the original repo checked out locally (i.e. `$GOPATH/src/github.com/tendermint/tendermint`)
-- `git remote rename origin upstream`
-- `git remote add origin git@github.com:ebuchman/basecoin.git`
+  * Create the fork on github, using the fork button.
+  * Go to the original repo checked out locally (i.e. `$GOPATH/src/github.com/tendermint/tendermint`)
+  * `git remote rename origin upstream`
+  * `git remote add origin git@github.com:ebuchman/basecoin.git`
 
-Now `origin` refers to my fork and `upstream` refers to the Tendermint version.
-So I can `git push -u origin main` to update my fork, and make pull requests to tendermint from there.
+Now `origin` refers to my fork and `upstream` refers to the tendermint version.
+So I can `git push -u origin master` to update my fork, and make pull requests to tendermint from there.
 Of course, replace `ebuchman` with your git handle.
 
 To pull in updates from the origin repo, run
 
-- `git fetch upstream`
-- `git rebase upstream/main` (or whatever branch you want)
+    * `git fetch upstream`
+    * `git rebase upstream/master` (or whatever branch you want)
+
+Please don't make Pull Requests to `master`.
 
 ## Dependencies
 
-We use [go modules](https://github.com/golang/go/wiki/Modules) to manage dependencies.
+We use [dep](https://github.com/golang/dep) to manage dependencies.
 
-That said, the `main` branch of every Tendermint repository should just build
+That said, the master branch of every Tendermint repository should just build
 with `go get`, which means they should be kept up-to-date with their
 dependencies so we can get away with telling people they can just `go get` our
 software.
 
 Since some dependencies are not under our control, a third party may break our
-build, in which case we can fall back on `go mod tidy`. Even for dependencies under our control, go helps us to
+build, in which case we can fall back on `dep ensure` (or `make
+get_vendor_deps`). Even for dependencies under our control, dep helps us to
 keep multiple repos in sync as they evolve. Anything with an executable, such
 as apps, tools, and the core, should use dep.
 
-Run `go list -u -m all` to get a list of dependencies that may not be
+Run `dep status` to get a list of vendor dependencies that may not be
 up-to-date.
 
-When updating dependencies, please only update the particular dependencies you
-need. Instead of running `go get -u=patch`, which will update anything,
-specify exactly the dependency you want to update, eg.
-`GO111MODULE=on go get -u github.com/tendermint/go-amino@master`.
+## Vagrant
 
-## Protobuf
+If you are a [Vagrant](https://www.vagrantup.com/) user, you can get started
+hacking Tendermint with the commands below.
 
-We use [Protocol Buffers](https://developers.google.com/protocol-buffers) along
-with [`gogoproto`](https://github.com/cosmos/gogoproto) to generate code for use
-across Tendermint Core.
+NOTE: In case you installed Vagrant in 2017, you might need to run
+`vagrant box update` to upgrade to the latest `ubuntu/xenial64`.
 
-To generate proto stubs, lint, and check protos for breaking changes, you will
-need to install [buf](https://buf.build/) and `gogoproto`. Then, from the root
-of the repository, run:
-
-```bash
-# Lint all of the .proto files in proto/tendermint
-make proto-lint
-
-# Check if any of your local changes (prior to committing to the Git repository)
-# are breaking
-make proto-check-breaking
-
-# Generate Go code from the .proto files in proto/tendermint
-make proto-gen
 ```
-
-To automatically format `.proto` files, you will need
-[`clang-format`](https://clang.llvm.org/docs/ClangFormat.html) installed. Once
-installed, you can run:
-
-```bash
-make proto-format
+vagrant up
+vagrant ssh
+make test
 ```
 
-### Visual Studio Code
-
-If you are a VS Code user, you may want to add the following to your `.vscode/settings.json`:
-
-```json
-{
-  "protoc": {
-    "options": [
-      "--proto_path=${workspaceRoot}/proto",
-    ]
-  }
-}
-```
-
-## Changelog
-
-Every fix, improvement, feature, or breaking change should be made in a
-pull-request that includes an update to the `CHANGELOG_PENDING.md` file.
-
-A feature can also be worked on a feature branch, if its size and/or risk
-justifies it (see #branching-model-and-release) below.
-
-### What does a good changelog entry look like?
-
-Changelog entries should answer the question: "what is important about this
-change for users to know?" or "what problem does this solve for users?". It
-should not simply be a reiteration of the title of the associated PR, unless the
-title of the PR _very_ clearly explains the benefit of a change to a user.
-
-Some good examples of changelog entry descriptions:
-
-```md
-- [consensus] \#1111 Small transaction throughput improvement (approximately
-  3-5\% from preliminary tests) through refactoring the way we use channels
-- [mempool] \#1112 Refactor Go API to be able to easily swap out the current
-  mempool implementation in Tendermint forks
-- [p2p] \#1113 Automatically ban peers when their messages are unsolicited or
-  are received too frequently
-```
-
-Some bad examples of changelog entry descriptions:
-
-```md
-- [consensus] \#1111 Refactor channel usage
-- [mempool] \#1112 Make API generic
-- [p2p] \#1113 Ban for PEX message abuse
-```

-

-- <https://docs.gitlab.com/ee/development/changelog.html#writing-good-changelog-entries>
-- <https://depfu.com/blog/what-makes-a-good-changelog>
-
-### Changelog entry format
-
-Changelog entries should be formatted as follows:
-
-```md
-- [module] \#xxx Some description of the change (@contributor)
-```
-
-Here, `module` is the part of the code that changed (typically a
-top-level Go package), `xxx` is the pull-request number, and `contributor`
-is the author/s of the change.
-
-It's also acceptable for `xxx` to refer to the relevant issue number, but pull-request
-numbers are preferred.
-Note this means pull-requests should be opened first so the changelog can then
-be updated with the pull-request's number.
-There is no need to include the full link, as this will be added
-automatically during release. But please include the backslash and pound, eg. `\#2313`.
-
-Changelog entries should be ordered alphabetically according to the
-`module`, and numerically according to the pull-request number.
-
-Changes with multiple classifications should be doubly included (eg. a bug fix
-that is also a breaking change should be recorded under both).
-
-Breaking changes are further subdivided according to the APIs/users they impact.
-Any change that affects multiple APIs/users should be recorded multiply - for
-instance, a change to the `Blockchain Protocol` that removes a field from the
-header should also be recorded under `CLI/RPC/Config` since the field will be
-removed from the header in RPC responses as well.
-
-## Branching Model and Release
-
-The main development branch is `main`.
-
-Every release is maintained in a release branch named `vX.Y.Z`.
-
-Pending minor releases have long-lived release candidate ("RC") branches. Minor release changes should be merged to these long-lived RC branches at the same time that the changes are merged to `main`.
-
-If a feature's size is big and/or its risk is high, it can be implemented in a feature branch.
-While the feature work is in progress,
-pull requests are open and squash merged against the feature branch.
-Branch `main` is periodically merged (merge commit) into the feature branch,
-to reduce branch divergence.
-When the feature is complete, the feature branch is merged back (merge commit) into `main`.
-The moment of the final merge can be carefully chosen
-so as to land different features in different releases.
-
-Note all pull requests should be squash merged except for merging to a release branch (named `vX.Y`). This keeps the commit history clean and makes it
-easy to reference the pull request where a change was introduced.
-
-### Development Procedure
-
-The latest state of development is on `main`, which must never fail `make test`. _Never_ force push `main`, unless fixing broken git history (which we rarely do anyways).
-
-To begin contributing, create a development branch either on `github.com/tendermint/tendermint`, or your fork (using `git remote add origin`).
-
-Make changes, and before submitting a pull request, update the `CHANGELOG_PENDING.md` to record your change. Also, run either `git rebase` or `git merge` on top of the latest `main`. (Since pull requests are squash-merged, either is fine!)
-
-Update the `UPGRADING.md` if the change you've made is breaking and the
-instructions should be in place for a user on how he/she can upgrade its
-software (ABCI application, Tendermint-based blockchain, light client, wallet).
-
-Once you have submitted a pull request label the pull request with either `R:minor`, if the change should be included in the next minor release, or `R:major`, if the change is meant for a major release.
-
-Sometimes (often!) pull requests get out-of-date with `main`, as other people merge different pull requests to `main`. It is our convention that pull request authors are responsible for updating their branches with `main`. (This also means that you shouldn't update someone else's branch for them; even if it seems like you're doing them a favor, you may be interfering with their git flow in some way!)
-
-#### Merging Pull Requests
-
-It is also our convention that authors merge their own pull requests, when possible. External contributors may not have the necessary permissions to do this, in which case, a member of the core team will merge the pull request once it's been approved.
-
-Before merging a pull request:
-
-- Ensure pull branch is up-to-date with a recent `main` (GitHub won't let you merge without this!)
-- Run `make test` to ensure that all tests pass
-- [Squash](https://stackoverflow.com/questions/5189560/squash-my-last-x-commits-together-using-git) merge pull request
-
-#### Pull Requests for Minor Releases
-
-If your change should be included in a minor release, please also open a PR against the long-lived minor release candidate branch (e.g., `rc1/v0.33.5`) _immediately after your change has been merged to main_.
-
-You can do this by cherry-picking your commit off `main`:
-
-```sh
-$ git checkout rc1/v0.33.5
-$ git checkout -b {new branch name}
-$ git cherry-pick {commit SHA from main}
-# may need to fix conflicts, and then use git add and git cherry-pick --continue
-$ git push origin {new branch name}
-```
-
-After this, you can open a PR. Please note in the PR body if there were merge conflicts so that reviewers can be sure to take a thorough look.
-
-### Git Commit Style
-
-We follow the [Go style guide on commit messages](https://tip.golang.org/doc/contribute.html#commit_messages). Write concise commits that start with the package name and have a description that finishes the sentence "This change modifies Tendermint to...". For example,
-
-```sh
-cmd/debug: execute p.Signal only when p is not nil
-
-[potentially longer description in the body]
-
-Fixes #nnnn
-```
-
-Each PR should have one commit once it lands on `main`; this can be accomplished by using the "squash and merge" button on Github. Be sure to edit your commit message, though!
-
 ## Testing
 
-### Unit tests
+All repos should be hooked up to [CircleCI](https://circleci.com/).
 
-Unit tests are located in `_test.go` files as directed by [the Go testing
-package](https://golang.org/pkg/testing/). If you're adding or removing a
-function, please check there's a `TestType_Method` test for it.
+If they have `.go` files in the root directory, they will be automatically
+tested by circle using `go test -v -race ./...`. If not, they will need a
+`circle.yml`. Ideally, every repo has a `Makefile` that defines `make test` and
+includes its continuous integration status using a badge in the `README.md`.
 
-Run: `make test`
+## Branching Model and Release
 
-### Integration tests
+User-facing repos should adhere to the branching model: http://nvie.com/posts/a-successful-git-branching-model/.
+That is, these repos should be well versioned, and any merge to master requires a version bump and tagged release.
 
-Integration tests are also located in `_test.go` files. What differentiates
-them is a more complicated setup, which usually involves setting up two or more
-components.
+Libraries need not follow the model strictly, but would be wise to,
+especially `go-p2p` and `go-rpc`, as their versions are referenced in tendermint core.
 
-Run: `make test_integrations`
+### Development Procedure:
+- the latest state of development is on `develop`
+- `develop` must never fail `make test`
+- no --force onto `develop` (except when reverting a broken commit, which should seldom happen)
+- create a development branch either on github.com/tendermint/tendermint, or your fork (using `git remote add origin`)
+- before submitting a pull request, begin `git rebase` on top of `develop`
 
-### End-to-end tests
+### Pull Merge Procedure:
+- ensure pull branch is rebased on develop
+- run `make test` to ensure that all tests pass
+- merge pull request
+- the `unstable` branch may be used to aggregate pull merges before testing once
+- push master may request that pull requests be rebased on top of `unstable`
 
-End-to-end tests are used to verify a fully integrated Tendermint network.
+### Release Procedure:
+- start on `develop`
+- run integration tests (see `test_integrations` in Makefile)
+- prepare changelog/release issue
+- bump versions
+- push to release-vX.X.X to run the extended integration tests on the CI
+- merge to master
+- merge master back to develop
 
-See [README](./test/e2e/README.md) for details.
-
-Run:
-
-```sh
-cd test/e2e && \
-  make && \
-  ./build/runner -f networks/ci.toml
-```
-
-### Model-based tests (ADVANCED)
-
-*NOTE: if you're just submitting your first PR, you won't need to touch these
-most probably (99.9%)*.
-
-For components, that have been [formally
-verified](https://en.wikipedia.org/wiki/Formal_verification) using
-[TLA+](https://en.wikipedia.org/wiki/TLA%2B), it may be possible to generate
-tests using a combination of the [Apalache Model
-Checker](https://apalache.informal.systems/) and [tendermint-rs testgen
-util](https://github.com/informalsystems/tendermint-rs/tree/master/testgen).
-
-Now, I know there's a lot to take in. If you want to learn more, check out [
-this video](https://www.youtube.com/watch?v=aveoIMphzW8) by Andrey Kupriyanov
-& Igor Konnov.
-
-At the moment, we have model-based tests for the light client, located in the
-`./light/mbt` directory.
-
-Run: `cd light/mbt && go test`
-
-### Fuzz tests (ADVANCED)
-
-*NOTE: if you're just submitting your first PR, you won't need to touch these
-most probably (99.9%)*.
-
-[Fuzz tests](https://en.wikipedia.org/wiki/Fuzzing) can be found inside the
-`./test/fuzz` directory. See [README.md](./test/fuzz/README.md) for details.
-
-Run: `cd test/fuzz && make fuzz-{PACKAGE-COMPONENT}`
-
-### Jepsen tests (ADVANCED)
-
-*NOTE: if you're just submitting your first PR, you won't need to touch these
-most probably (99.9%)*.
-
-[Jepsen](http://jepsen.io/) tests are used to verify the
-[linearizability](https://jepsen.io/consistency/models/linearizable) property
-of the Tendermint consensus. They are located in a separate repository
--> <https://github.com/tendermint/jepsen>. Please refer to its README for more
-information.
-
-### RPC Testing
-
-**If you contribute to the RPC endpoints it's important to document your
-changes in the [Openapi file](./rpc/openapi/openapi.yaml)**.
-
-To test your changes you must install `nodejs` and run:
-
-```bash
-npm i -g dredd
-make build-linux build-contract-tests-hooks
-make contract-tests
-```
-
-**WARNING: these are currently broken due to <https://github.com/apiaryio/dredd>
-not supporting complete OpenAPI 3**.
-
-This command will popup a network and check every endpoint against what has
-been documented.
+### Hotfix Procedure:
+- start on `master`
+- checkout a new branch named hotfix-vX.X.X
+- make the required changes
+  - these changes should be small and an absolute necessity
+  - add a note to CHANGELOG.md
+- bump versions
+- push to hotfix-vX.X.X to run the extended integration tests on the CI
+- merge hotfix-vX.X.X to master
+- merge hotfix-vX.X.X to develop
+- delete the hotfix-vX.X.X branch

-# Design goals
-
-The design goals for Tendermint (and the SDK and related libraries) are:
-
-* Simplicity and Legibility
-* Parallel performance, namely ability to utilize multicore architecture
-* Ability to evolve the codebase bug-free
-* Debuggability
-* Complete correctness that considers all edge cases, esp in concurrency
-* Future-proof modular architecture, message protocol, APIs, and encapsulation
-
-
-## Justification
-
-Legibility is key to maintaining bug-free software as it evolves toward more
-optimizations, more ease of debugging, and additional features.
-
-It is too easy to introduce bugs over time by replacing lines of code with
-those that may panic, which means ideally locks are unlocked by defer
-statements.
-
-For example,
-
-```go
-func (obj *MyObj) something() {
-	mtx.Lock()
-	obj.something = other
-	mtx.Unlock()
-}
-```
-
-It is too easy to refactor the codebase in the future to replace `other` with
-`other.String()` for example, and this may introduce a bug that causes a
-deadlock.  So as much as reasonably possible, we need to be using defer
-statements, even though it introduces additional overhead.
-
-If it is necessary to optimize the unlocking of mutex locks, the solution is
-more modularity via smaller functions, so that defer'd unlocks are scoped
-within a smaller function.
-
-Similarly, idiomatic for-loops should always be preferred over those that use
-custom counters, because it is too easy to evolve the body of a for-loop to
-become more complicated over time, and it becomes more and more difficult to
-assess the correctness of such a for-loop by visual inspection.
-
-
-## On performance
-
-It doesn't matter whether there are alternative implementations that are 2x or
-3x more performant, when the software doesn't work, deadlocks, or if bugs
-cannot be debugged.  By taking advantage of multicore concurrency, the
-Tendermint implementation will at least be an order of magnitude within the
-range of what is theoretically possible.  The design philosophy of Tendermint,
-and the choice of Go as implementation language, is designed to make Tendermint
-implementation the standard specification for concurrent BFT software.
-
-By focusing on the message protocols (e.g. ABCI, p2p messages), and
-encapsulation e.g. IAVL module, (relatively) independent reactors, we are both
-implementing a standard implementation to be used as the specification for
-future implementations in more optimizable languages like Rust, Java, and C++;
-as well as creating sufficiently performant software. Tendermint Core will
-never be as fast as future implementations of the Tendermint Spec, because Go
-isn't designed to be as fast as possible.  The advantage of using Go is that we
-can develop the whole stack of modular components **faster** than in other
-languages.
-
-Furthermore, the real bottleneck is in the application layer, and it isn't
-necessary to support more than a sufficiently decentralized set of validators
-(e.g. 100 ~ 300 validators is sufficient, with delegated bonded PoS).
-
-Instead of optimizing Tendermint performance down to the metal, lets focus on
-optimizing on other matters, namely ability to push feature complete software
-that works well enough, can be debugged and maintained, and can serve as a spec
-for future implementations.
-
-
-## On encapsulation
-
-In order to create maintainable, forward-optimizable software, it is critical
-to develop well-encapsulated objects that have well understood properties, and
-to re-use these easy-to-use-correctly components as building blocks for further
-encapsulated meta-objects.
-
-For example, mutexes are cheap enough for Tendermint's design goals when there
-isn't goroutine contention, so it is encouraged to create concurrency safe
-structures with struct-level mutexes.  If they are used in the context of
-non-concurrent logic, then the performance is good enough.  If they are used in
-the context of concurrent logic, then it will still perform correctly.
-
-Examples of this design principle can be seen in the types.ValidatorSet struct,
-and the rand.Rand struct.  It's one single struct declaration that can be used
-in both concurrent and non-concurrent logic, and due to its well encapsulation,
-it's easy to get the usage of the mutex right.
-
-### example: rand.Rand
-
-`The default Source is safe for concurrent use by multiple goroutines, but
-Sources created by NewSource are not`.  The reason why the default
-package-level source is safe for concurrent use is because it is protected (see
-`lockedSource` in <https://golang.org/src/math/rand/rand.go>).
-
-But we shouldn't rely on the global source, we should be creating our own
-Rand/Source instances and using them, especially for determinism in testing.
-So it is reasonable to have rand.Rand be protected by a mutex.  Whether we want
-our own implementation of Rand is another question, but the answer there is
-also in the affirmative.  Sometimes you want to know where Rand is being used
-in your code, so it becomes a simple matter of dropping in a log statement to
-inject inspectability into Rand usage.  Also, it is nice to be able to extend
-the functionality of Rand with custom methods.  For these reasons, and for the
-reasons which is outlined in this design philosophy document, we should
-continue to use the rand.Rand object, with mutex protection.
-
-Another key aspect of good encapsulation is the choice of exposed vs unexposed
-methods.  It should be clear to the reader of the code, which methods are
-intended to be used in what context, and what safe usage is.  Part of this is
-solved by hiding methods via unexported methods.  Another part of this is
-naming conventions on the methods (e.g. underscores) with good documentation,
-and code organization.  If there are too many exposed methods and it isn't
-clear what methods have what side effects, then there is something wrong about
-the design of abstractions that should be revisited.
-
-
-## On concurrency
-
-In order for Tendermint to remain relevant in the years to come, it is vital
-for Tendermint to take advantage of multicore architectures.  Due to the nature
-of the problem, namely consensus across a concurrent p2p gossip network, and to
-handle RPC requests for a large number of consuming subscribers, it is
-unavoidable for Tendermint development to require expertise in concurrency
-design, especially when it comes to the reactor design, and also for RPC
-request handling.
-
-
-# Guidelines
-
-Here are some guidelines for designing for (sufficient) performance and concurrency:
-
-* Mutex locks are cheap enough when there isn't contention.
-* Do not optimize code without analytical or observed proof that it is in a hot path.
-* Don't over-use channels when mutex locks w/ encapsulation are sufficient.
-* The need to drain channels are often a hint of unconsidered edge cases.
-* The creation of O(N) one-off goroutines is generally technical debt that
-   needs to get addressed sooner than later.  Avoid creating too many
-goroutines as a patch around incomplete concurrency design, or at least be
-aware of the debt and do not invest in the debt.  On the other hand, Tendermint
-is designed to have a limited number of peers (e.g. 10 or 20), so the creation
-of O(C) goroutines per O(P) peers is still O(C\*P=constant).
-* Use defer statements to unlock as much as possible.  If you want to unlock sooner,
-    try to create more modular functions that do make use of defer statements.
-
-# Mantras
-
-* Premature optimization kills
-* Readability is paramount
-* Beautiful is better than fast.
-* In the face of ambiguity, refuse the temptation to guess.
-* In the face of bugs, refuse the temptation to cover the bug.
-* There should be one-- and preferably only one --obvious way to do it.

-## Documentation
+## A Note on Production Readiness
 
-Complete documentation can be found on the
-[website](https://docs.tendermint.com/).
+While Tendermint is being used in production in private, permissioned
+environments, we are still working actively to harden and audit it in preparation
+for use in public blockchains, such as the [Cosmos Network](https://cosmos.network/).
+We are also still making breaking changes to the protocol and the APIs.
+Thus, we tag the releases as *alpha software*.
 
-## Releases
-
-Please do not depend on `main` as your production branch. Use
-[releases](https://github.com/tendermint/tendermint/releases) instead.
-
-Tendermint has been in the production of private and public environments, most
-notably the blockchains of the Cosmos Network. we haven't released v1.0 yet
-since we are making breaking changes to the protocol and the APIs. See below for
-more details about [versioning](#versioning).
-
-In any case, if you intend to run Tendermint in production, we're happy to help.
-You can contact us [over email](mailto:hello@interchain.io) or [join the
-chat](https://discord.gg/cosmosnetwork).

-## Versioning
-
-### Semantic Versioning
-
-Tendermint uses [Semantic Versioning](http://semver.org/) to determine when and
-how the version changes. According to SemVer, anything in the public API can
-change at any time before version 1.0.0
-
-To provide some stability to users of 0.X.X versions of Tendermint, the MINOR
-version is used to signal breaking changes across Tendermint's API. This API
-includes all publicly exposed types, functions, and methods in non-internal Go
-packages as well as the types and methods accessible via the Tendermint RPC
-interface.
-
-Breaking changes to these public APIs will be documented in the CHANGELOG.
-
-### Upgrades
-
-In an effort to avoid accumulating technical debt prior to 1.0.0, we do not
-guarantee that breaking changes (ie. bumps in the MINOR version) will work with
-existing Tendermint blockchains. In these cases you will have to start a new
-blockchain, or write something custom to get the old data into the new chain.
-However, any bump in the PATCH version should be compatible with existing
-blockchain histories.
-
-For more information on upgrading, see [UPGRADING.md](./UPGRADING.md).
-
-### Supported Versions
-
-Because we are a small core team, we have limited capacity to ship patch
-updates, including security updates. Consequently, we strongly recommend keeping
-Tendermint up-to-date. Upgrading instructions can be found in
-[UPGRADING.md](./UPGRADING.md).
-
-Currently supported versions include:
-
-- v0.34.x
-- v0.37.x (release candidate)
+- [Single node](/docs/tendermint-core/using-tendermint.md)
+- [Local cluster using docker-compose](/networks/local)
+- [Remote cluster using terraform and ansible](/docs/networks/terraform-and-ansible.md)

+### SemVer
+
+Tendermint uses [SemVer](http://semver.org/) to determine when and how the version changes.
+According to SemVer, anything in the public API can change at any time before version 1.0.0
+
+To provide some stability to Tendermint users in these 0.X.X days, the MINOR version is used
+to signal breaking changes across a subset of the total public API. This subset includes all
+interfaces exposed to other processes (cli, rpc, p2p, etc.), but does not
+include the in-process Go APIs.
+
+That said, breaking changes in the following packages will be documented in the
+CHANGELOG even if they don't lead to MINOR version bumps:
+
+- types
+- rpc/client
+- config
+- node
+- libs
+  - bech32
+  - common
+  - db
+  - errors
+  - log
+
+Exported objects in these packages that are not covered by the versioning scheme
+are explicitly marked by `// UNSTABLE` in their go doc comment and may change at any
+time without notice. Functions, types, and values in any other package may also change at any time.
+
+### Upgrades
+
+In an effort to avoid accumulating technical debt prior to 1.0.0,
+we do not guarantee that breaking changes (ie. bumps in the MINOR version)

RELEASES.md

@@ -1,373 +0,0 @@
-# Releases
-
-Tendermint uses modified [semantic versioning](https://semver.org/) with each
-release following a `vX.Y.Z` format. Tendermint is currently on major version 0
-and uses the minor version to signal breaking changes. The `main` branch is
-used for active development and thus it is not advisable to build against it.
-
-The latest changes are always initially merged into `main`. Releases are
-specified using tags and are built from long-lived "backport" branches that are
-cut from `main` when the release process begins. Each release "line" (e.g.
-0.34 or 0.33) has its own long-lived backport branch, and the backport branches
-have names like `v0.34.x` or `v0.33.x` (literally, `x`; it is not a placeholder
-in this case). Tendermint only maintains the last two releases at a time (the
-oldest release is predominantly just security patches).
-
-## Backporting
-
-As non-breaking changes land on `main`, they should also be backported to
-these backport branches.
-
-We use Mergify's [backport feature](https://mergify.io/features/backports) to
-automatically backport to the needed branch. There should be a label for any
-backport branch that you'll be targeting. To notify the bot to backport a pull
-request, mark the pull request with the label corresponding to the correct
-backport branch. For example, to backport to v0.38.x, add the label
-`S:backport-to-v0.38.x`. Once the original pull request is merged, the bot will
-try to cherry-pick the pull request to the backport branch. If the bot fails to
-backport, it will open a pull request. The author of the original pull request
-is responsible for solving the conflicts and merging the pull request.
-
-### Creating a backport branch
-
-If this is the first release candidate for a minor version release, e.g.
-v0.25.0, you get to have the honor of creating the backport branch!
-
-Note that, after creating the backport branch, you'll also need to update the
-tags on `main` so that `go mod` is able to order the branches correctly. You
-should tag `main` with a "dev" tag that is "greater than" the backport
-branches tags. See [#6072](https://github.com/tendermint/tendermint/pull/6072)
-for more context.
-
-In the following example, we'll assume that we're making a backport branch for
-the 0.38.x line.
-
-1. Start on `main`
-
-2. Ensure that there is a [branch protection
-   rule](https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/defining-the-mergeability-of-pull-requests/managing-a-branch-protection-rule) for the
-   branch you are about to create (you will need admin access to the repository
-   in order to do this).
-
-3. Create and push the backport branch:
-
-   ```sh
-   git checkout -b v0.38.x
-   git push origin v0.38.x
-   ```
-
-4. Create a PR to update the documentation directory for the backport branch.
-
-   We rewrite any URLs pointing to `main` to point to the backport branch,
-   so that generated documentation will link to the correct versions of files
-   elsewhere in the repository. The following files are to be excluded from this
-   search:
-
-   * [`README.md`](./README.md)
-   * [`CHANGELOG.md`](./CHANGELOG.md)
-   * [`UPGRADING.md`](./UPGRADING.md)
-
-   The following links are to always point to `main`, regardless of where they
-   occur in the codebase:
-
-   * `https://github.com/tendermint/tendermint/blob/main/LICENSE`
-
-   Be sure to search for all of the following links and replace `main` with your
-   corresponding branch label or version (e.g. `v0.38.x` or `v0.38`):
-
-   * `github.com/tendermint/tendermint/blob/main` ->
-     `github.com/tendermint/tendermint/blob/v0.38.x`
-   * `github.com/tendermint/tendermint/tree/main` ->
-     `github.com/tendermint/tendermint/tree/v0.38.x`
-   * `docs.tendermint.com/main` -> `docs.tendermint.com/v0.38`
-
-   Once you have updated all of the relevant documentation:
-
-   ```sh
-   # Create and push the PR.
-   git checkout -b update-docs-v038x
-   git commit -m "Update docs for v0.38.x backport branch."
-   git push -u origin update-docs-v038x
-   ```
-
-   Be sure to merge this PR before making other changes on the newly-created
-   backport branch.
-
-After doing these steps, go back to `main` and do the following:
-
-1. Create a new workflow to run e2e nightlies for the new backport branch. (See
-   [e2e-nightly-main.yml][e2e] for an example.)
-
-2. Add a new section to the Mergify config (`.github/mergify.yml`) to enable the
-   backport bot to work on this branch, and add a corresponding `S:backport-to-v0.38.x`
-   [label](https://github.com/tendermint/tendermint/labels) so the bot can be triggered.
-
-3. Add a new section to the Dependabot config (`.github/dependabot.yml`) to
-   enable automatic update of Go dependencies on this branch. Copy and edit one
-   of the existing branch configurations to set the correct `target-branch`.

-
-## Pre-releases
-
-Before creating an official release, especially a minor release, we may want to
-create an alpha or beta version, or release candidate (RC) for our friends and
-partners to test out. We use git tags to create pre-releases, and we build them
-off of backport branches, for example:
-
-* `v0.38.0-alpha.1` - The first alpha release of `v0.38.0`. Subsequent alpha
-  releases will be numbered `v0.38.0-alpha.2`, `v0.38.0-alpha.3`, etc.
-
-  Alpha releases are to be considered the _most_ unstable of pre-releases, and
-  are most likely not yet properly QA'd. These are made available to allow early
-  adopters to start integrating and testing new functionality before we're done
-  with QA.
-
-* `v0.38.0-beta.1` - The first beta release of `v0.38.0`. Subsequent beta
-  releases will be numbered `v0.38.0-beta.2`, `v0.38.0-beta.3`, etc.
-
-  Beta releases can be considered more stable than alpha releases in that we
-  will have QA'd them better than alpha releases, but there still may be
-  minor breaking API changes if users have strong demands for such changes.
-
-* `v0.38.0-rc1` - The first release candidate (RC) of `v0.38.0`. Subsequent RCs
-  will be numbered `v0.38.0-rc2`, `v0.38.0-rc3`, etc.
-
-  RCs are considered more stable than beta releases in that we will have
-  completed our QA on them. APIs will most likely be stable at this point. The
-  difference between an RC and a release is that there may still be small
-  changes (bug fixes, features) that may make their way into the series before
-  cutting a final release.
-
-(Note that branches and tags _cannot_ have the same names, so it's important
-that these branches have distinct names from the tags/release names.)
-
-If this is the first pre-release for a minor release, you'll have to make a new
-backport branch (see above). Otherwise:
-
-1. Start from the backport branch (e.g. `v0.38.x`).
-2. Run the integration tests and the E2E nightlies
-   (which can be triggered from the GitHub UI;
-   e.g., <https://github.com/tendermint/tendermint/actions/workflows/e2e-nightly-37x.yml>).
-3. Prepare the pre-release documentation:
-   * Ensure that all relevant changes are in the `CHANGELOG_PENDING.md` file.
-     This file's contents must only be included in the `CHANGELOG.md` when we
-     cut final releases.
-   * Ensure that `UPGRADING.md` is up-to-date and includes notes on any breaking changes
-      or other upgrading flows.
-4. Prepare the versioning:
-   * Bump TMVersionDefault version in  `version.go`
-   * Bump P2P and block protocol versions in  `version.go`, if necessary.
-     Check the changelog for breaking changes in these components.
-   * Bump ABCI protocol version in `version.go`, if necessary
-5. Open a PR with these changes against the backport branch.
-6. Once these changes have landed on the backport branch, be sure to pull them back down locally.
-7. Once you have the changes locally, create the new tag, specifying a name and a tag "message":
-   `git tag -a v0.38.0-rc1 -m "Release Candidate v0.38.0-rc1`
-8. Push the tag back up to origin:
-   `git push origin v0.38.0-rc1`
-   Now the tag should be available on the repo's releases page.
-9. Future pre-releases will continue to be built off of this branch.
-
-## Minor release
-
-This minor release process assumes that this release was preceded by release
-candidates. If there were no release candidates, begin by creating a backport
-branch, as described above.
-
-Before performing these steps, be sure the
-[Minor Release Checklist](#minor-release-checklist) has been completed.
-
-1. Start on the backport branch (e.g. `v0.38.x`)
-2. Run integration tests (`make test_integrations`) and the e2e nightlies.
-3. Prepare the release:
-   * "Squash" changes from the changelog entries for the pre-releases into a
-     single entry, and add all changes included in `CHANGELOG_PENDING.md`.
-     (Squashing includes both combining all entries, as well as removing or
-     simplifying any intra-pre-release changes. It may also help to alphabetize
-     the entries by package name.)
-   * Run `python ./scripts/linkify_changelog.py CHANGELOG.md` to add links for
-     all PRs
-   * Ensure that `UPGRADING.md` is up-to-date and includes notes on any breaking changes
-      or other upgrading flows.
-   * Bump TMVersionDefault version in  `version.go`
-   * Bump P2P and block protocol versions in  `version.go`, if necessary
-   * Bump ABCI protocol version in `version.go`, if necessary
-4. Open a PR with these changes against the backport branch.
-5. Once these changes are on the backport branch, push a tag with prepared release details.
-   This will trigger the actual release `v0.38.0`.
-   * `git tag -a v0.38.0 -m 'Release v0.38.0'`
-   * `git push origin v0.38.0`
-6. Make sure that `main` is updated with the latest `CHANGELOG.md`, `CHANGELOG_PENDING.md`, and `UPGRADING.md`.
-7. Add the release to the documentation site generator config (see
-   [DOCS\_README.md](./docs/DOCS_README.md) for more details). In summary:
-   * Start on branch `main`.
-   * Add a new line at the bottom of [`docs/versions`](./docs/versions) to
-     ensure the newest release is the default for the landing page.
-   * Add a new entry to `themeConfig.versions` in
-     [`docs/.vuepress/config.js`](./docs/.vuepress/config.js) to include the
-	 release in the dropdown versions menu.
-   * Commit these changes to `main` and backport them into the backport
-     branch for this release.
-
-## Patch release
-
-Patch releases are done differently from minor releases: They are built off of
-long-lived backport branches, rather than from main.  As non-breaking changes
-land on `main`, they should also be backported into these backport branches.
-
-Patch releases don't have release candidates by default, although any tricky
-changes may merit a release candidate.
-
-To create a patch release:
-
-1. Checkout the long-lived backport branch: `git checkout v0.38.x`
-2. Run integration tests (`make test_integrations`) and the nightlies.
-3. Check out a new branch and prepare the release:
-   * Copy `CHANGELOG_PENDING.md` to top of `CHANGELOG.md`
-   * Run `python ./scripts/linkify_changelog.py CHANGELOG.md` to add links for all issues
-   * Run `bash ./scripts/authors.sh` to get a list of authors since the latest release, and add the GitHub aliases of external contributors to the top of the CHANGELOG. To lookup an alias from an email, try `bash ./scripts/authors.sh <email>`
-   * Reset the `CHANGELOG_PENDING.md`
-   * Bump the TMDefaultVersion in `version.go`
-   * Bump the ABCI version number, if necessary.
-     (Note that ABCI follows semver, and that ABCI versions are the only versions
-     which can change during patch releases, and only field additions are valid patch changes.)
-4. Open a PR with these changes that will land them back on `v0.38.x`
-5. Once this change has landed on the backport branch, make sure to pull it locally, then push a tag.
-   * `git tag -a v0.38.1 -m 'Release v0.38.1'`
-   * `git push origin v0.38.1`
-6. Create a pull request back to main with the CHANGELOG & version changes from the latest release.
-   * Remove all `R:patch` labels from the pull requests that were included in the release.
-   * Do not merge the backport branch into main.
-
-## Minor Release Checklist
-
-The following set of steps are performed on all releases that increment the
-_minor_ version, e.g. v0.25 to v0.26. These steps ensure that Tendermint is well
-tested, stable, and suitable for adoption by the various diverse projects that
-rely on Tendermint.
-
-### Feature Freeze
-
-Ahead of any minor version release of Tendermint, the software enters 'Feature
-Freeze' for at least two weeks. A feature freeze means that _no_ new features
-are added to the code being prepared for release. No code changes should be made
-to the code being released that do not directly improve pressing issues of code
-quality. The following must not be merged during a feature freeze:
-
-* Refactors that are not related to specific bug fixes.
-* Dependency upgrades.
-* New test code that does not test a discovered regression.
-* New features of any kind.
-* Documentation or spec improvements that are not related to the newly developed
-  code.
-
-This period directly follows the creation of the [backport
-branch](#creating-a-backport-branch). The Tendermint team instead directs all
-attention to ensuring that the existing code is stable and reliable. Broken
-tests are fixed, flakey-tests are remedied, end-to-end test failures are
-thoroughly diagnosed and all efforts of the team are aimed at improving the
-quality of the code. During this period, the upgrade harness tests are run
-repeatedly and a variety of in-house testnets are run to ensure Tendermint
-functions at the scale it will be used by application developers and node
-operators.
-
-### Nightly End-To-End Tests
-
-The Tendermint team maintains [a set of end-to-end
-tests](https://github.com/tendermint/tendermint/blob/main/test/e2e/README.md#L1)
-that run each night on the latest commit of the project and on the code in the
-tip of each supported backport branch. These tests start a network of
-containerized Tendermint processes and run automated checks that the network
-functions as expected in both stable and unstable conditions. During the feature
-freeze, these tests are run nightly and must pass consistently for a release of
-Tendermint to be considered stable.
-
-### Upgrade Harness
-
-> TODO(williambanfield): Change to past tense and clarify this section once
-> upgrade harness is complete.
-
-The Tendermint team is creating an upgrade test harness to exercise the workflow
-of stopping an instance of Tendermint running one version of the software and
-starting up the same application running the next version. To support upgrade
-testing, we will add the ability to terminate the Tendermint process at specific
-pre-defined points in its execution so that we can verify upgrades work in a
-representative sample of stop conditions.
-
-### Large Scale Testnets
-
-The Tendermint end-to-end tests run a small network (~10s of nodes) to exercise
-basic consensus interactions. Real world deployments of Tendermint often have
-over a hundred nodes just in the validator set, with many others acting as full
-nodes and sentry nodes. To gain more assurance before a release, we will also
-run larger-scale test networks to shake out emergent behaviors at scale.
-
-Large-scale test networks are run on a set of virtual machines (VMs). Each VM is
-equipped with 4 Gigabytes of RAM and 2 CPU cores. The network runs a very simple
-key-value store application. The application adds artificial delays to different
-ABCI calls to simulate a slow application. Each testnet is briefly run with no
-load being generated to collect a baseline performance. Once baseline is
-captured, a consistent load is applied across the network. This load takes the
-form of 10% of the running nodes all receiving a consistent stream of two
-hundred transactions per minute each.
-
-During each test net, the following metrics are monitored and collected on each
-node:
-
-* Consensus rounds per height
-* Maximum connected peers, Minimum connected peers, Rate of change of peer connections
-* Memory resident set size
-* CPU utilization
-* Blocks produced per minute
-* Seconds for each step of consensus (Propose, Prevote, Precommit, Commit)
-* Latency to receive block proposals
-
-For these tests we intentionally target low-powered host machines (with low core
-counts and limited memory) to ensure we observe similar kinds of resource contention
-and limitation that real-world  deployments of Tendermint experience in production.
-
-#### 200 Node Testnet
-
-To test the stability and performance of Tendermint in a real world scenario,
-a 200 node test network is run. The network comprises 5 seed nodes, 100
-validators and 95 non-validating full nodes. All nodes begin by dialing
-a subset of the seed nodes to discover peers. The network is run for several
-days, with metrics being collected continuously. In cases of changes to performance
-critical systems, testnets of larger sizes should be considered.
-
-#### Rotating Node Testnet
-
-Real-world deployments of Tendermint frequently see new nodes arrive and old
-nodes exit the network. The rotating node testnet ensures that Tendermint is
-able to handle this reliably. In this test, a network with 10 validators and
-3 seed nodes is started. A rolling set of 25 full nodes are started and each
-connects to the network by dialing one of the seed nodes. Once the node is able
-to blocksync to the head of the chain and begins producing blocks using
-Tendermint consensus it is stopped. Once stopped, a new node is started and
-takes its place. This network is run for several days.
-
-#### Network Partition Testnet
-
-Tendermint is expected to recover from network partitions. A partition where no
-subset of the nodes is left with the super-majority of the stake is expected to
-stop making blocks. Upon alleviation of the partition, the network is expected
-to once again become fully connected and capable of producing blocks. The
-network partition testnet ensures that Tendermint is able to handle this
-reliably at scale. In this test, a network with 100 validators and 95 full
-nodes is started. All validators have equal stake. Once the network is
-producing blocks, a set of firewall rules is deployed to create a partitioned
-network with 50% of the stake on one side and 50% on the other. Once the
-network stops producing blocks, the firewall rules are removed and the nodes
-are monitored to ensure they reconnect and that the network again begins
-producing blocks.
-
-#### Absent Stake Testnet
-
-Tendermint networks often run with _some_ portion of the voting power offline.
-The absent stake testnet ensures that large networks are able to handle this
-reliably. A set of 150 validator nodes and three seed nodes is started. The set
-of 150 validators is configured to only possess a cumulative stake of 67% of
-the total stake. The remaining 33% of the stake is configured to belong to
-a validator that is never actually run in the test network. The network is run
-for multiple days, ensuring that it is able to produce blocks without issue.

-## Reporting a Bug
+As part of our [Coordinated Vulnerability Disclosure
+Policy](https://tendermint.com/security), we operate a bug bounty.
+See the policy for more details on submissions and rewards.
 
-As part of our [Coordinated Vulnerability Disclosure Policy](https://tendermint.com/security),
-we operate a [bug bounty][hackerone]. See the policy for more
-details on submissions and rewards, and see "Example Vulnerabilities" (below)
-for examples of the kinds of bugs we're most interested in.
+Here is a list of examples of the kinds of bugs we're most interested in:
 
-### Guidelines
+## Specification
 
-We require that all researchers:
+- Conceptual flaws
+- Ambiguities, inconsistencies, or incorrect statements
+- Mis-match between specification and implementation of any component
 
-* Use the bug bounty to disclose all vulnerabilities, and avoid posting
-  vulnerability information in public places, including Github Issues, Discord
-  channels, and Telegram groups
-* Make every effort to avoid privacy violations, degradation of user experience,
-  disruption to production systems (including but not limited to the Cosmos
-  Hub), and destruction of data
-* Keep any information about vulnerabilities that you’ve discovered confidential
-  between yourself and the Tendermint Core engineering team until the issue has
-  been resolved and disclosed
-* Avoid posting personally identifiable information, privately or publicly
-
-If you follow these guidelines when reporting an issue to us, we commit to:
-
-* Not pursue or support any legal action related to your research on this
-  vulnerability
-* Work with you to understand, resolve and ultimately disclose the issue in a
-  timely fashion
-
-## Disclosure Process
-
-Tendermint Core uses the following disclosure process:
-
-1. Once a security report is received, the Tendermint Core team works to verify
-   the issue and confirm its severity level using CVSS.
-2. The Tendermint Core team collaborates with the Gaia team to determine the
-   vulnerability’s potential impact on the Cosmos Hub.
-3. Patches are prepared for eligible releases of Tendermint in private
-   repositories. See “Supported Releases” below for more information on which
-   releases are considered eligible.
-4. If it is determined that a CVE-ID is required, we request a CVE through a CVE
-   Numbering Authority.
-5. We notify the community that a security release is coming, to give users time
-   to prepare their systems for the update. Notifications can include forum
-   posts, tweets, and emails to partners and validators, including emails sent
-   to the [Tendermint Security Mailing List][tmsec-mailing].
-6. 24 hours following this notification, the fixes are applied publicly and new
-   releases are issued.
-7. Cosmos SDK and Gaia update their Tendermint Core dependencies to use these
-   releases, and then themselves issue new releases.
-8. Once releases are available for Tendermint Core, Cosmos SDK and Gaia, we
-   notify the community, again, through the same channels as above. We also
-   publish a Security Advisory on Github and publish the CVE, as long as neither
-   the Security Advisory nor the CVE include any information on how to exploit
-   these vulnerabilities beyond what information is already available in the
-   patch itself.
-9. Once the community is notified, we will pay out any relevant bug bounties to
-   submitters.
-10. One week after the releases go out, we will publish a post with further
-    details on the vulnerability as well as our response to it.
-
-This process can take some time. Every effort will be made to handle the bug in
-as timely a manner as possible, however it's important that we follow the
-process described above to ensure that disclosures are handled consistently and
-to keep Tendermint Core and its downstream dependent projects--including but not
-limited to Gaia and the Cosmos Hub--as secure as possible.
-

STYLE_GUIDE.md

@@ -1,162 +0,0 @@
-# Go Coding Style Guide
-
-In order to keep our code looking good with lots of programmers working on it, it helps to have a "style guide", so all
-the code generally looks quite similar. This doesn't mean there is only one "right way" to write code, or even that this
-standard is better than your style.  But if we agree to a number of stylistic practices, it makes it much easier to read
-and modify new code. Please feel free to make suggestions if there's something you would like to add or modify.
-
-We expect all contributors to be familiar with [Effective Go](https://golang.org/doc/effective_go.html)
-(and it's recommended reading for all Go programmers anyways). Additionally, we generally agree with the suggestions
- in [Uber's style guide](https://github.com/uber-go/guide/blob/master/style.md) and use that as a starting point.
-
-
-## Code Structure
-
-Perhaps more key for code readability than good commenting is having the right structure. As a rule of thumb, try to write
-in a logical order of importance, taking a little time to think how to order and divide the code such that someone could
-scroll down and understand the functionality of it just as well as you do. A loose example of such order would be:
-
-* Constants, global and package-level variables
-* Main Struct
-* Options (only if they are seen as critical to the struct else they should be placed in another file)
-* Initialization / Start and stop of the service
-* Msgs/Events
-* Public Functions (In order of most important)
-* Private/helper functions
-* Auxiliary structs and function (can also be above private functions or in a separate file)
-
-## General
-
-* Use `gofmt` (or `goimport`) to format all code upon saving it.  (If you use VIM, check out vim-go).
-* Use a linter (see below) and generally try to keep the linter happy (where it makes sense).
-* Think about documentation, and try to leave godoc comments, when it will help new developers.
-* Every package should have a high level doc.go file to describe the purpose of that package, its main functions, and any other relevant information.
-* `TODO` should not be used. If important enough should be recorded as an issue.
-* `BUG` / `FIXME` should be used sparingly to guide future developers on some of the vulnerabilities of the code.
-* `XXX` can be used in work-in-progress (prefixed with "WIP:" on github) branches but they must be removed before approving a PR.
-* Applications (e.g. clis/servers) *should* panic on unexpected unrecoverable errors and print a stack trace.
-
-## Comments
-
-* Use a space after comment deliminter (ex. `// your comment`).
-* Many comments are not sentences. These should begin with a lower case letter and end without a period.
-* Conversely, sentences in comments should be sentenced-cased and end with a period.
-
-## Linters
-
-These must be applied to all (Go) repos.
-
-* [shellcheck](https://github.com/koalaman/shellcheck)
-* [golangci-lint](https://github.com/golangci/golangci-lint) (covers all important linters)
-    * See the `.golangci.yml` file in each repo for linter configuration.
-
-## Various
-
-* Reserve "Save" and "Load" for long-running persistence operations. When parsing bytes, use "Encode" or "Decode".
-* Maintain consistency across the codebase.
-* Functions that return functions should have the suffix `Fn`
-* Names should not [stutter](https://blog.golang.org/package-names). For example, a struct generally shouldn’t have
-  a field named after itself; e.g., this shouldn't occur:
-
-``` golang
-type middleware struct {
-	middleware Middleware
-}
-```
-
-* In comments, use "iff" to mean, "if and only if".
-* Product names are capitalized, like "Tendermint", "Basecoin", "Protobuf", etc except in command lines: `tendermint --help`
-* Acronyms are all capitalized, like "RPC", "gRPC", "API".  "MyID", rather than "MyId".
-* Prefer errors.New() instead of fmt.Errorf() unless you're actually using the format feature with arguments.
-
-## Importing Libraries
-
-Sometimes it's necessary to rename libraries to avoid naming collisions or ambiguity.
-
-* Use [goimports](https://godoc.org/golang.org/x/tools/cmd/goimports)
-* Separate imports into blocks - one for the standard lib, one for external libs and one for application libs.
-* Here are some common library labels for consistency:
-    * dbm "github.com/tendermint/tm-db"
-    * tmcmd "github.com/tendermint/tendermint/cmd/tendermint/commands"
-    * tmcfg "github.com/tendermint/tendermint/config/tendermint"
-    * tmtypes "github.com/tendermint/tendermint/types"
-* Never use anonymous imports (the `.`), for example, `tmlibs/common` or anything else.
-* When importing a pkg from the `tendermint/libs` directory, prefix the pkg alias with tm.
-    * tmbits "github.com/tendermint/tendermint/libs/bits"
-* tip: Use the `_` library import to import a library for initialization effects (side effects)
-
-## Dependencies
-
-* Dependencies should be pinned by a release tag, or specific commit, to avoid breaking `go get` when external dependencies are updated.
-* Refer to the [contributing](CONTRIBUTING.md) document for more details
-
-## Testing
-
-* The first rule of testing is: we add tests to our code
-* The second rule of testing is: we add tests to our code
-* For Golang testing:
-    * Make use of table driven testing where possible and not-cumbersome
-        * [Inspiration](https://dave.cheney.net/2013/06/09/writing-table-driven-tests-in-go)
-    * Make use of [assert](https://godoc.org/github.com/stretchr/testify/assert) and [require](https://godoc.org/github.com/stretchr/testify/require)
-* When using mocks, it is recommended to use Testify [mock](<https://pkg.go.dev/github.com/stretchr/testify/mock>
- ) along with [Mockery](https://github.com/vektra/mockery) for autogeneration
-
-## Errors
-
-* Ensure that errors are concise, clear and traceable.
-* Use stdlib errors package.
-* For wrapping errors, use `fmt.Errorf()` with `%w`.
-* Panic is appropriate when an internal invariant of a system is broken, while all other cases (in particular,
-  incorrect or invalid usage) should return errors.
-
-## Config
-
-* Currently the TOML filetype is being used for config files
-* A good practice is to store per-user config files under `~/.[yourAppName]/config.toml`
-
-## CLI
-
-* When implementing a CLI use [Cobra](https://github.com/spf13/cobra) and [Viper](https://github.com/spf13/viper).
-* Helper messages for commands and flags must be all lowercase.
-* Instead of using pointer flags (eg. `FlagSet().StringVar`) use Viper to retrieve flag values (eg. `viper.GetString`)
-    * The flag key used when setting and getting the flag should always be stored in a
-   variable taking the form `FlagXxx` or `flagXxx`.
-    * Flag short variable descriptions should always start with a lower case character as to remain consistent with
-   the description provided in the default `--help` flag.
-
-## Version
-
-* Every repo should have a version/version.go file that mimics the Tendermint Core repo
-* We read the value of the constant version in our build scripts and hence it has to be a string
-
-## Non-Go Code
-
-* All non-Go code (`*.proto`, `Makefile`, `*.sh`), where there is no common
-   agreement on style, should be formatted according to
-   [EditorConfig](http://editorconfig.org/) config:
-
-   ```toml
-   # top-most EditorConfig file
-   root = true
-
-   # Unix-style newlines with a newline ending every file
-   [*]
-   charset = utf-8
-   end_of_line = lf
-   insert_final_newline = true
-   trim_trailing_whitespace = true
-
-   [Makefile]
-   indent_style = tab
-
-   [*.sh]
-   indent_style = tab
-
-   [*.proto]
-   indent_style = space
-   indent_size = 2
-   ```
-
-   Make sure the file above (`.editorconfig`) are in the root directory of your
-   repo and you have a [plugin for your
-   editor](http://editorconfig.org/#download) installed.

 # Upgrading Tendermint Core
 
-This guide provides instructions for upgrading to specific versions of
-Tendermint Core.
-
-## Unreleased
-
-## Config Changes
-
-* A new config field, `BootstrapPeers` has been introduced as a means of
-  adding a list of addresses to the addressbook upon initializing a node. This is an
-  alternative to `PersistentPeers`. `PersistentPeers` shold be only used for
-  nodes that you want to keep a constant connection with i.e. sentry nodes
-
-----
-
-### ABCI Changes
-
-* The `ABCIVersion` is now `1.0.0`.
-
-* Added new ABCI methods `PrepareProposal` and `ProcessProposal`. For details,
-  please see the [spec](spec/abci/README.md). Applications upgrading to
-  v0.37.0 must implement these methods, at the very minimum, as described
-  [here](./spec/abci/abci++_app_requirements.md)
-* Deduplicated `ConsensusParams` and `BlockParams`.
-  In the v0.34 branch they are defined both in `abci/types.proto` and `types/params.proto`.
-  The definitions in `abci/types.proto` have been removed.
-  In-process applications should make sure they are not using the deleted
-  version of those structures.
-* In v0.34, messages on the wire used to be length-delimited with `int64` varint
-  values, which was inconsistent with the `uint64` varint length delimiters used
-  in the P2P layer. Both now consistently use `uint64` varint length delimiters.
-* Added `AbciVersion` to `RequestInfo`.
-  Applications should check that Tendermint's ABCI version matches the one they expect
-  in order to ensure compatibility.
-* The `SetOption` method has been removed from the ABCI `Client` interface.
-  The corresponding Protobuf types have been deprecated.
-* The `key` and `value` fields in the `EventAttribute` type have been changed
-  from type `bytes` to `string`. As per the [Protocol Buffers updating
-  guidelines](https://developers.google.com/protocol-buffers/docs/proto3#updating),
-  this should have no effect on the wire-level encoding for UTF8-encoded
-  strings.
-
-## v0.34.24
-
-Note that in [\#9724](https://github.com/tendermint/tendermint/pull/9724) we
-un-prettified the JSON output (i.e. removed all indentation) of the HTTP and
-WebSocket RPC for performance and subscription stability reasons. We recommend
-using a tool such as [jq](https://github.com/stedolan/jq) to obtain prettified
-output if you rely on that prettified output in some way.
-
-## v0.34.20
-
-### Feature: Priority Mempool
-
-This release backports an implementation of the Priority Mempool from the v0.35
-branch. This implementation of the mempool permits the application to set a
-priority on each transaction during CheckTx, and during block selection the
-highest-priority transactions are chosen (subject to the constraints on size
-and gas cost).
-
-Operators can enable the priority mempool by setting `mempool.version` to
-`"v1"` in the `config.toml`. For more technical details about the priority
-mempool, see [ADR 067: Mempool
-Refactor](https://github.com/tendermint/tendermint/blob/main/docs/architecture/adr-067-mempool-refactor.md).
-
-## v0.34.0
-
-**Upgrading to Tendermint 0.34 requires a blockchain restart.**
-This release is not compatible with previous blockchains due to changes to
-the encoding format (see "Protocol Buffers," below) and the block header (see "Blockchain Protocol").
-
-Note also that Tendermint 0.34 also requires Go 1.16 or higher.
-
-### ABCI Changes
-
-* The `ABCIVersion` is now `0.17.0`.
-
-* New ABCI methods (`ListSnapshots`, `LoadSnapshotChunk`, `OfferSnapshot`, and `ApplySnapshotChunk`)
-  were added to support the new State Sync feature.
-  Previously, syncing a new node to a preexisting network could take days; but with State Sync,
-  new nodes are able to join a network in a matter of seconds.
-  Read [the spec](https://github.com/tendermint/tendermint/blob/v0.34.x/spec/abci/apps.md#state-sync)
-  if you want to learn more about State Sync, or if you'd like your application to use it.
-  (If you don't want to support State Sync in your application, you can just implement these new
-  ABCI methods as no-ops, leaving them empty.)
-
-* `KV.Pair` has been replaced with `abci.EventAttribute`. The `EventAttribute.Index` field
-  allows ABCI applications to dictate which events should be indexed.
-
-* The blockchain can now start from an arbitrary initial height,
-  provided to the application via `RequestInitChain.InitialHeight`.
-
-* ABCI evidence type is now an enum with two recognized types of evidence:
-  `DUPLICATE_VOTE` and `LIGHT_CLIENT_ATTACK`.
-  Applications should be able to handle these evidence types
-  (i.e., through slashing or other accountability measures).
-
-* The [`PublicKey` type](https://github.com/tendermint/tendermint/blob/main/proto/tendermint/crypto/keys.proto#L13-L15)
-  (used in ABCI as part of `ValidatorUpdate`) now uses a `oneof` protobuf type.
-  Note that since Tendermint only supports ed25519 validator keys, there's only one
-  option in the `oneof`.  For more, see "Protocol Buffers," below.
-
-* The field `Proof`, on the ABCI type `ResponseQuery`, is now named `ProofOps`.
-  For more, see "Crypto," below.
-
-### P2P Protocol
-
-The default codec is now proto3, not amino. The schema files can be found in the `/proto`
-directory. For more, see "Protobuf," below.
-
-### Blockchain Protocol
-
-* `Header#LastResultsHash`, which is the root hash of a Merkle tree built from
-  `ResponseDeliverTx(Code, Data)` as of v0.34 also includes `GasWanted` and `GasUsed`
-  fields.
-
-* Merkle hashes of empty trees previously returned nothing, but now return the hash of an empty input,
-  to conform with [RFC-6962](https://tools.ietf.org/html/rfc6962).
-  This mainly affects `Header#DataHash`, `Header#LastResultsHash`, and
-  `Header#EvidenceHash`, which are often empty. Non-empty hashes can also be affected, e.g. if their
-  inputs depend on other (empty) Merkle hashes, giving different results.
-
-### Transaction Indexing

-Tendermint now relies on the application to tell it which transactions to index. This means that
-in the `config.toml`, generated by Tendermint, there is no longer a way to specify which
-transactions to index. `tx.height` and `tx.hash` will always be indexed when using the `kv` indexer.
-
-Applications must now choose to either a) enable indexing for all transactions, or
-b) allow node operators to decide which transactions to index.
-Applications can notify Tendermint to index a specific transaction by setting
-`Index: bool` to `true` in the Event Attribute:
-
-```go
-[]types.Event{
-	{
-		Type: "app",
-		Attributes: []types.EventAttribute{
-			{Key: []byte("creator"), Value: []byte("Cosmoshi Netowoko"), Index: true},
-		},
-	},
-}
-```
-
-### Protocol Buffers
-
-Tendermint 0.34 replaces Amino with Protocol Buffers for encoding.
-This migration is extensive and results in a number of changes, however,
-Tendermint only uses the types generated from Protocol Buffers for disk and
-wire serialization.
-**This means that these changes should not affect you as a Tendermint user.**
-
-However, Tendermint users and contributors may note the following changes:
-
-* Directory layout changes: All proto files have been moved under one directory, `/proto`.
-  This is in line with the recommended file layout by [Buf](https://buf.build).
-  For more, see the [Buf documentation](https://buf.build/docs/lint-checkers#file_layout).
-* ABCI Changes: As noted in the "ABCI Changes" section above, the `PublicKey` type now uses
-  a `oneof` type.
-
-For more on the Protobuf changes, please see our [blog post on this migration](https://medium.com/tendermint/tendermint-0-34-protocol-buffers-and-you-8c40558939ae).
-
-### Consensus Parameters
-
-Tendermint 0.34 includes new and updated consensus parameters.
-
-#### Version Parameters (New)
-
-* `AppVersion`, which is the version of the ABCI application.
-
-#### Evidence Parameters
-
-* `MaxBytes`, which caps the total amount of evidence. The default is 1048576 (1 MB).
-
-### Crypto
-
-#### Keys
-
-* Keys no longer include a type prefix. For example, ed25519 pubkeys have been renamed from
-  `PubKeyEd25519` to `PubKey`. This reduces stutter (e.g., `ed25519.PubKey`).
-* Keys are now byte slices (`[]byte`) instead of byte arrays (`[<size>]byte`).
-* The multisig functionality that was previously in Tendermint now has
-  a new home within the Cosmos SDK:
-  [`cosmos/cosmos-sdk/types/multisig`](https://github.com/cosmos/cosmos-sdk/blob/master/crypto/types/multisig/multisignature.go).
-
-#### `merkle` Package
-
-* `SimpleHashFromMap()` and `SimpleProofsFromMap()` were removed.
-* The prefix `Simple` has been removed. (For example, `SimpleProof` is now called `Proof`.)
-* All protobuf messages have been moved to the `/proto` directory.
-* The protobuf message `Proof` that contained multiple ProofOp's has been renamed to `ProofOps`.
-  As noted above, this affects the ABCI type `ResponseQuery`:
-  The field that was named Proof is now named `ProofOps`.
-* `HashFromByteSlices` and `ProofsFromByteSlices` now return a hash for empty inputs, to conform with
-  [RFC-6962](https://tools.ietf.org/html/rfc6962).
-
-### `libs` Package
-
-The `bech32` package has moved to the Cosmos SDK:
-[`cosmos/cosmos-sdk/types/bech32`](https://github.com/cosmos/cosmos-sdk/tree/4173ea5ebad906dd9b45325bed69b9c655504867/types/bech32).
-
-### CLI
-
-The `tendermint lite` command has been renamed to `tendermint light` and has a slightly different API.
-See [the docs](https://docs.tendermint.com/v0.33/tendermint-core/light-client-protocol.html#http-proxy) for details.
-
-### Light Client
-
-We have a new, rewritten light client! You can
-[read more](https://medium.com/tendermint/everything-you-need-to-know-about-the-tendermint-light-client-f80d03856f98)
-about the justifications and details behind this change.
-
-Other user-relevant changes include:
-
-* The old `lite` package was removed; the new light client uses the `light` package.
-* The `Verifier` was broken up into two pieces:
-    * Core verification logic (pure `VerifyX` functions)
-    * `Client` object, which represents the complete light client
-* The new light client stores headers and validator sets as `LightBlock`s
-* The RPC client can be found in the `/rpc` directory.
-* The HTTP(S) proxy is located in the `/proxy` directory.
-
-### `state` Package
-
-* A new field `State.InitialHeight` has been added to record the initial chain height, which must be `1`
-  (not `0`) if starting from height `1`. This can be configured via the genesis field `initial_height`.
-* The `state` package now has a `Store` interface. All functions in
-  [state/store.go](https://github.com/tendermint/tendermint/blob/56911ee35298191c95ef1c7d3d5ec508237aaff4/state/store.go#L42-L42)
-  are now part of the interface. The interface returns errors on all methods and can be used by calling `state.NewStore(dbm.DB)`.
-
-### `privval` Package
-
-All requests are now accompanied by the chain ID from the network.
-This is a optional field and can be ignored by key management systems;
-however, if you are using the same key management system for multiple different
-blockchains, we recommend that you check the chain ID.
-
-
-### RPC
-
-* `/unsafe_start_cpu_profiler`, `/unsafe_stop_cpu_profiler` and
-  `/unsafe_write_heap_profile` were removed.
-   For profiling, please use the pprof server, which can
-  be enabled through `--rpc.pprof_laddr=X` flag or `pprof_laddr=X` config setting
-  in the rpc section.
-* The `Content-Type` header returned on RPC calls is now (correctly) set as `application/json`.
-
-### Version
-
-Version is now set through Go linker flags `ld_flags`. Applications that are using tendermint as a library should set this at compile time.
-
-Example:
-
-```sh
-go install -mod=readonly -ldflags "-X github.com/tendermint/tendermint/version.TMCoreSemVer=$(go list -m github.com/tendermint/tendermint | sed  's/ /\@/g') -s -w " -trimpath ./cmd
-```
-
-Additionally, the exported constant `version.Version` is now `version.TMCoreSemVer`.
-
-## v0.33.4
-
-### Go API
-
-* `rpc/client` HTTP and local clients have been moved into `http` and `local`
-  subpackages, and their constructors have been renamed to `New()`.
-
-### Protobuf Changes
-
-When upgrading to version 0.33.4 you will have to fetch the `third_party`
-directory along with the updated proto files.
-
-### Block Retention
-
-ResponseCommit added a field for block retention. The application can provide information to Tendermint on how to prune blocks.
-If an application would like to not prune any blocks pass a `0` in this field.
-
-```proto
-message ResponseCommit {
-  // reserve 1
-  bytes  data          = 2; // the Merkle root hash
-  ++ uint64 retain_height = 3; // the oldest block height to retain ++
-}
-```
-
-## v0.33.0
-
-This release is not compatible with previous blockchains due to commit becoming
-signatures only and fields in the header have been removed.
-
-### Blockchain Protocol
-
-`TotalTxs` and `NumTxs` were removed from the header. `Commit` now consists
-mostly of just signatures.
-
-```go
-type Commit struct {
-	Height     int64
-	Round      int
-	BlockID    BlockID
-	Signatures []CommitSig
-}
-```
-
-```go
-type BlockIDFlag byte
-
-const (
-	// BlockIDFlagAbsent - no vote was received from a validator.
-	BlockIDFlagAbsent BlockIDFlag = 0x01
-	// BlockIDFlagCommit - voted for the Commit.BlockID.
-	BlockIDFlagCommit = 0x02
-	// BlockIDFlagNil - voted for nil.
-	BlockIDFlagNil = 0x03
-)
-
-type CommitSig struct {
-	BlockIDFlag      BlockIDFlag
-	ValidatorAddress Address
-	Timestamp        time.Time
-	Signature        []byte
-}
-```
-
-See [\#63](https://github.com/tendermint/spec/pull/63) for the complete spec
-change.
-
-### P2P Protocol
-
-The secret connection now includes a transcript hashing. If you want to
-implement a handshake (or otherwise have an existing implementation), you'll
-need to make the same changes that were made
-[here](https://github.com/tendermint/tendermint/pull/3668).
-
-### Config Changes
-
-You will need to generate a new config if you have used a prior version of tendermint.
-
-Tags have been entirely renamed throughout the codebase to events and there
-keys are called
-[compositeKeys](https://github.com/tendermint/tendermint/blob/6d05c531f7efef6f0619155cf10ae8557dd7832f/docs/app-dev/indexing-transactions.md).
-
-Evidence Params has been changed to include duration.
-
-* `consensus_params.evidence.max_age_duration`.
-* Renamed `consensus_params.evidence.max_age` to `max_age_num_blocks`.
-
-### Go API
-
-* `libs/common` has been removed in favor of specific pkgs.
-    * `async`
-    * `service`
-    * `rand`
-    * `net`
-    * `strings`
-    * `cmap`
-* removal of `errors` pkg
-
-### RPC Changes
-
-* `/validators` is now paginated (default: 30 vals per page)
-* `/block_results` response format updated [see RPC docs for details](https://docs.tendermint.com/v0.33/rpc/#/Info/block_results)
-* Event suffix has been removed from the ID in event responses
-* IDs are now integers not `json-client-XYZ`
-
-## v0.32.0
-
-This release is compatible with previous blockchains,
-however the new ABCI Events mechanism may create some complexity
-for nodes wishing to continue operation with v0.32 from a previous version.
-There are some minor breaking changes to the RPC.
-
-### Config Changes
-
-If you have `db_backend` set to `leveldb` in your config file, please change it
-to `goleveldb` or `cleveldb`.
-
-### RPC Changes
-
-The default listen address for the RPC is now `127.0.0.1`. If you want to expose
-it publicly, you have to explicitly configure it. Note exposing the RPC to the
-public internet may not be safe - endpoints which return a lot of data may
-enable resource exhaustion attacks on your node, causing the process to crash.
-
-Any consumers of `/block_results` need to be mindful of the change in all field
-names from CamelCase to Snake case, eg. `results.DeliverTx` is now `results.deliver_tx`.
-This is a fix, but it's breaking.
-
-### ABCI Changes
-
-ABCI responses which previously had a `Tags` field now have an `Events` field
-instead. The original `Tags` field was simply a list of key-value pairs, where
-each key effectively represented some attribute of an event occuring in the
-blockchain, like `sender`, `receiver`, or `amount`. However, it was difficult to
-represent the occurence of multiple events (for instance, multiple transfers) in a single list.
-The new `Events` field contains a list of `Event`, where each `Event` is itself a list
-of key-value pairs, allowing for more natural expression of multiple events in
-eg. a single DeliverTx or EndBlock. Note each `Event` also includes a `Type`, which is meant to categorize the
-event.
-
-For transaction indexing, the index key is
-prefixed with the event type: `{eventType}.{attributeKey}`.
-If the same event type and attribute key appear multiple times, the values are
-appended in a list.
-
-To make queries, include the event type as a prefix. For instance if you
-previously queried for `recipient = 'XYZ'`, and after the upgrade you name your event `transfer`,
-the new query would be for `transfer.recipient = 'XYZ'`.
-
-Note that transactions indexed on a node before upgrading to v0.32 will still be indexed
-using the old scheme. For instance, if a node upgraded at height 100,
-transactions before 100 would be queried with `recipient = 'XYZ'` and
-transactions after 100 would be queried with `transfer.recipient = 'XYZ'`.
-While this presents additional complexity to clients, it avoids the need to
-reindex. Of course, you can reset the node and sync from scratch to re-index
-entirely using the new scheme.
-
-We illustrate further with a more complete example.
-
-Prior to the update, suppose your `ResponseDeliverTx` look like:
-
-```go
-abci.ResponseDeliverTx{
-  Tags: []kv.Pair{
-    {Key: []byte("sender"), Value: []byte("foo")},
-    {Key: []byte("recipient"), Value: []byte("bar")},
-    {Key: []byte("amount"), Value: []byte("35")},
-  }
-}
-```
-
-The following queries would match this transaction:
-
-```go
-query.MustParse("tm.event = 'Tx' AND sender = 'foo'")
-query.MustParse("tm.event = 'Tx' AND recipient = 'bar'")
-query.MustParse("tm.event = 'Tx' AND sender = 'foo' AND recipient = 'bar'")
-```
-
-Following the upgrade, your `ResponseDeliverTx` would look something like:
-the following `Events`:
-
-```go
-abci.ResponseDeliverTx{
-  Events: []abci.Event{
-    {
-      Type: "transfer",
-      Attributes: kv.Pairs{
-        {Key: []byte("sender"), Value: []byte("foo")},
-        {Key: []byte("recipient"), Value: []byte("bar")},
-        {Key: []byte("amount"), Value: []byte("35")},
-      },
-    }
-}
-```
-
-Now the following queries would match this transaction:
-
-```go
-query.MustParse("tm.event = 'Tx' AND transfer.sender = 'foo'")
-query.MustParse("tm.event = 'Tx' AND transfer.recipient = 'bar'")
-query.MustParse("tm.event = 'Tx' AND transfer.sender = 'foo' AND transfer.recipient = 'bar'")
-```
-
-For further documentation on `Events`, see the [docs](https://github.com/tendermint/tendermint/blob/60827f75623b92eff132dc0eff5b49d2025c591e/docs/spec/abci/abci.md#events).
-
-### Go Applications
-
-The ABCI Application interface changed slightly so the CheckTx and DeliverTx
-methods now take Request structs. The contents of these structs are just the raw
-tx bytes, which were previously passed in as the argument.
-
-## v0.31.6
-
-There are no breaking changes in this release except Go API of p2p and
-mempool packages. Hovewer, if you're using cleveldb, you'll need to change
-the compilation tag:
-
-Use `cleveldb` tag instead of `gcc` to compile Tendermint with CLevelDB or
-use `make build_c` / `make install_c` (full instructions can be found at
-<https://docs.tendermint.com/v0.33/introduction/install.html#compile-with-cleveldb-support>)
-
-## v0.31.0
-
-This release contains a breaking change to the behavior of the pubsub system.
-It also contains some minor breaking changes in the Go API and ABCI.
-There are no changes to the block or p2p protocols, so v0.31.0 should work fine
-with blockchains created from the v0.30 series.
-
-### RPC
-
-The pubsub no longer blocks on publishing. This may cause some WebSocket (WS) clients to stop working as expected.
-If your WS client is not consuming events fast enough, Tendermint can terminate the subscription.
-In this case, the WS client will receive an error with description:
-
-```json
-{
-  "jsonrpc": "2.0",
-  "id": "{ID}#event",
-  "error": {
-    "code": -32000,
-    "msg": "Server error",
-    "data": "subscription was canceled (reason: client is not pulling messages fast enough)" // or "subscription was canceled (reason: Tendermint exited)"
-  }
-}
-
-Additionally, there are now limits on the number of subscribers and
-subscriptions that can be active at once. See the new
-`rpc.max_subscription_clients` and `rpc.max_subscriptions_per_client` values to
-configure this.
-```
-
-### Applications
-
-Simple rename of `ConsensusParams.BlockSize` to `ConsensusParams.Block`.
-
-The `ConsensusParams.Block.TimeIotaMS` field was also removed. It's configured
-in the ConsensusParsm in genesis.
-
-### Go API
-
-See the [CHANGELOG](CHANGELOG.md). These are relatively straight forward.
-
-## v0.30.0
-
-This release contains a breaking change to both the block and p2p protocols,
-however it may be compatible with blockchains created with v0.29.0 depending on
-the chain history. If your blockchain has not included any pieces of evidence,
-or no piece of evidence has been included in more than one block,
-and if your application has never returned multiple updates
-for the same validator in a single block, then v0.30.0 will work fine with
-blockchains created with v0.29.0.
-
-The p2p protocol change is to fix the proposer selection algorithm again.
-Note that proposer selection is purely a p2p concern right
-now since the algorithm is only relevant during real time consensus.
-This change is thus compatible with v0.29.0, but
-all nodes must be upgraded to avoid disagreements on the proposer.
-
-### Applications
-
-Applications must ensure they do not return duplicates in
-`ResponseEndBlock.ValidatorUpdates`. A pubkey must only appear once per set of
-updates. Duplicates will cause irrecoverable failure. If you have a very good
-reason why we shouldn't do this, please open an issue.
-
-## v0.29.0
-
-This release contains some breaking changes to the block and p2p protocols,
-and will not be compatible with any previous versions of the software, primarily
-due to changes in how various data structures are hashed.
-
-Any implementations of Tendermint blockchain verification, including lite clients,
-will need to be updated. For specific details:
-
-* [Merkle tree](https://github.com/tendermint/tendermint/blob/main/spec/blockchain/encoding.md#merkle-trees)
-* [ConsensusParams](https://github.com/tendermint/tendermint/blob/main/spec/blockchain/state.md#consensusparams)
-
-There was also a small change to field ordering in the vote struct. Any
-implementations of an out-of-process validator (like a Key-Management Server)
-will need to be updated. For specific details:
-
-* [Vote](https://github.com/tendermint/tendermint/blob/main/spec/consensus/signing.md#votes)
-
-Finally, the proposer selection algorithm continues to evolve. See the
-[work-in-progress
-specification](https://github.com/tendermint/tendermint/pull/3140).
-
-For everything else, please see the [CHANGELOG](./CHANGELOG.md#v0.29.0).
-
-## v0.28.0
-
-This release breaks the format for the `priv_validator.json` file
-and the protocol used for the external validator process.
-It is compatible with v0.27.0 blockchains (neither the BlockProtocol nor the
-P2PProtocol have changed).
-
-Please read carefully for details about upgrading.
-
-**Note:** Backup your `config/priv_validator.json`
-before proceeding.
-
-### `priv_validator.json`
-
-The `config/priv_validator.json` is now two files:
-`config/priv_validator_key.json` and `data/priv_validator_state.json`.
-The former contains the key material, the later contains the details on the last
-message signed.
-
-When running v0.28.0 for the first time, it will back up any pre-existing
-`priv_validator.json` file and proceed to split it into the two new files.
-Upgrading should happen automatically without problem.
-
-To upgrade manually, use the provided `privValUpgrade.go` script, with exact paths for the old
-`priv_validator.json` and the locations for the two new files. It's recomended
-to use the default paths, of `config/priv_validator_key.json` and
-`data/priv_validator_state.json`, respectively:
-
-```sh
-go run scripts/privValUpgrade.go <old-path> <new-key-path> <new-state-path>
-```
-
-### External validator signers
-
-The Unix and TCP implementations of the remote signing validator
-have been consolidated into a single implementation.
-Thus in both cases, the external process is expected to dial
-Tendermint. This is different from how Unix sockets used to work, where
-Tendermint dialed the external process.
-
-The `PubKeyMsg` was also split into separate `Request` and `Response` types
-for consistency with other messages.
-
-Note that the TCP sockets don't yet use a persistent key,
-so while they're encrypted, they can't yet be properly authenticated.
-See [#3105](https://github.com/tendermint/tendermint/issues/3105).
-Note the Unix socket has neither encryption nor authentication, but will
-add a shared-secret in [#3099](https://github.com/tendermint/tendermint/issues/3099).
-
-## v0.27.0
-
-This release contains some breaking changes to the block and p2p protocols,
-but does not change any core data structures, so it should be compatible with
-existing blockchains from the v0.26 series that only used Ed25519 validator keys.
-Blockchains using Secp256k1 for validators will not be compatible. This is due
-to the fact that we now enforce which key types validators can use as a
-consensus param. The default is Ed25519, and Secp256k1 must be activated
-explicitly.
-
-It is recommended to upgrade all nodes at once to avoid incompatibilities at the
-peer layer - namely, the heartbeat consensus message has been removed (only
-relevant if `create_empty_blocks=false` or `create_empty_blocks_interval > 0`),
-and the proposer selection algorithm has changed. Since proposer information is
-never included in the blockchain, this change only affects the peer layer.
-
-### Go API Changes
-
-#### libs/db
-
-The ReverseIterator API has changed the meaning of `start` and `end`.
-Before, iteration was from `start` to `end`, where
-`start > end`. Now, iteration is from `end` to `start`, where `start < end`.
-The iterator also excludes `end`. This change allows a simplified and more
-intuitive logic, aligning the semantic meaning of `start` and `end` in the
-`Iterator` and `ReverseIterator`.
-
-### Applications
-
-This release enforces a new consensus parameter, the
-ValidatorParams.PubKeyTypes. Applications must ensure that they only return
-validator updates with the allowed PubKeyTypes. If a validator update includes a
-pubkey type that is not included in the ConsensusParams.Validator.PubKeyTypes,
-block execution will fail and the consensus will halt.
-
-By default, only Ed25519 pubkeys may be used for validators. Enabling
-Secp256k1 requires explicit modification of the ConsensusParams.
-Please update your application accordingly (ie. restrict validators to only be
-able to use Ed25519 keys, or explicitly add additional key types to the genesis
-file).

+a newer version of Tendermint Core.

-## Installation & Usage
-
-To get up and running quickly, see the [getting started guide](../docs/app-dev/getting-started.md) along with the [abci-cli documentation](../docs/app-dev/abci-cli.md) which will go through the examples found in the [examples](./example/) directory.
+The community has provided a number of addtional implementations, see the [Tendermint Ecosystem](https://tendermint.com/ecosystem)
 
 ## Specification
 
 A detailed description of the ABCI methods and message types is contained in:
 
-- [The main spec](https://github.com/tendermint/tendermint/blob/main/spec/abci/README.md)
-- [A protobuf file](../proto/tendermint/types/types.proto)
-- [A Go interface](./types/application.go)
+- [A prose specification](specification.md)
+- [A protobuf file](https://github.com/tendermint/tendermint/blob/master/abci/types/types.proto)
+- [A Go interface](https://github.com/tendermint/tendermint/blob/master/abci/types/application.go).
+
+For more background information on ABCI, motivations, and tendermint, please visit [the documentation](https://tendermint.com/docs/).
+The two guides to focus on are the `Application Development Guide` and `Using ABCI-CLI`.

+
+## Install ABCI-CLI
+
+The `abci-cli` is a simple tool for debugging ABCI servers and running some
+example apps. To install it:
+
+```
+mkdir -p $GOPATH/src/github.com/tendermint
+cd $GOPATH/src/github.com/tendermint
+git clone https://github.com/tendermint/tendermint.git
+cd tendermint
+make get_tools
+make get_vendor_deps
+make install_abci
+```
+
+## Implementation
+
+We provide three implementations of the ABCI in Go:
+
+- Golang in-process
+- ABCI-socket
+- GRPC
+
+Note the GRPC version is maintained primarily to simplify onboarding and prototyping and is not receiving the same
+attention to security and performance as the others
+
+### In Process
+
+The simplest implementation just uses function calls within Go.
+This means ABCI applications written in Golang can be compiled with TendermintCore and run as a single binary.
+
+See the [examples](#examples) below for more information.
+
+### Socket (TSP)
+
+ABCI is best implemented as a streaming protocol.
+The socket implementation provides for asynchronous, ordered message passing over unix or tcp.
+Messages are serialized using Protobuf3 and length-prefixed with a [signed Varint](https://developers.google.com/protocol-buffers/docs/encoding?csw=1#signed-integers)
+
+For example, if the Protobuf3 encoded ABCI message is `0xDEADBEEF` (4 bytes), the length-prefixed message is `0x08DEADBEEF`, since `0x08` is the signed varint
+encoding of `4`. If the Protobuf3 encoded ABCI message is 65535 bytes long, the length-prefixed message would be like `0xFEFF07...`.
+
+Note the benefit of using this `varint` encoding over the old version (where integers were encoded as `<len of len><big endian len>` is that
+it is the standard way to encode integers in Protobuf. It is also generally shorter.
+
+### GRPC
+
+GRPC is an rpc framework native to Protocol Buffers with support in many languages.
+Implementing the ABCI using GRPC can allow for faster prototyping, but is expected to be much slower than
+the ordered, asynchronous socket protocol. The implementation has also not received as much testing or review.
+
+Note the length-prefixing used in the socket implementation does not apply for GRPC.
+
+## Usage
+
+The `abci-cli` tool wraps an ABCI client and can be used for probing/testing an ABCI server.
+For instance, `abci-cli test` will run a test sequence against a listening server running the Counter application (see below).
+It can also be used to run some example applications.
+See [the documentation](https://tendermint.com/docs/) for more details.
+
+### Examples
+
+Check out the variety of example applications in the [example directory](example/).
+It also contains the code refered to by the `counter` and `kvstore` apps; these apps come
+built into the `abci-cli` binary.
+
+#### Counter
+
+The `abci-cli counter` application illustrates nonce checking in transactions. It's code looks like:
+
+```golang
+func cmdCounter(cmd *cobra.Command, args []string) error {
+
+	app := counter.NewCounterApplication(flagSerial)
+
+	logger := log.NewTMLogger(log.NewSyncWriter(os.Stdout))
+
+	// Start the listener
+	srv, err := server.NewServer(flagAddrC, flagAbci, app)
+	if err != nil {
+		return err
+	}
+	srv.SetLogger(logger.With("module", "abci-server"))
+	if err := srv.Start(); err != nil {
+		return err
+	}
+
+	// Wait forever
+	cmn.TrapSignal(func() {
+		// Cleanup
+		srv.Stop()
+	})
+	return nil
+}
+```
+
+and can be found in [this file](cmd/abci-cli/abci-cli.go).
+
+#### kvstore
+
+The `abci-cli kvstore` application, which illustrates a simple key-value Merkle tree
+
+```golang
+func cmdKVStore(cmd *cobra.Command, args []string) error {
+	logger := log.NewTMLogger(log.NewSyncWriter(os.Stdout))
+
+	// Create the application - in memory or persisted to disk
+	var app types.Application
+	if flagPersist == "" {
+		app = kvstore.NewKVStoreApplication()
+	} else {
+		app = kvstore.NewPersistentKVStoreApplication(flagPersist)
+		app.(*kvstore.PersistentKVStoreApplication).SetLogger(logger.With("module", "kvstore"))
+	}
+
+	// Start the listener
+	srv, err := server.NewServer(flagAddrD, flagAbci, app)
+	if err != nil {
+		return err
+	}
+	srv.SetLogger(logger.With("module", "abci-server"))
+	if err := srv.Start(); err != nil {
+		return err
+	}
+
+	// Wait forever
+	cmn.TrapSignal(func() {
+		// Cleanup
+		srv.Stop()
+	})
+	return nil
+}
+```
