ABCI Specification
==================
NOTE: this file has moved to `specification.md <./specification.md>`__. It is left to prevent link breakages for the forseable future. It can safely be deleted in a few months.
Message Types
~~~~~~~~~~~~~
ABCI requests/responses are defined as simple Protobuf messages in `this
schema
file <https://github.com/tendermint/abci/blob/master/types/types.proto>`__.
TendermintCore sends the requests, and the ABCI application sends the
responses. Here, we provide an overview of the messages types and how they
are used by Tendermint. Then we describe each request-response pair as a
function with arguments and return values, and add some notes on usage.
Some messages (``Echo, Info, InitChain, BeginBlock, EndBlock, Commit``), don't
return errors because an error would indicate a critical failure in the
application and there's nothing Tendermint can do. The problem should be
addressed and both Tendermint and the application restarted. All other
messages (``SetOption, Query, CheckTx, DeliverTx``) return an
application-specific response ``Code uint32``, where only ``0`` is reserved for
``OK``.
Some messages (``SetOption, Query, CheckTx, DeliverTx``) return
non-deterministic data in the form of ``Info`` and ``Log``. The ``Log`` is
intended for the literal output from the application's logger, while the
``Info`` is any additional info that should be returned.
The first time a new blockchain is started, Tendermint calls ``InitChain``.
From then on, the Block Execution Sequence that causes the committed state to
be updated is as follows:
``BeginBlock, [DeliverTx], EndBlock, Commit``
where one ``DeliverTx`` is called for each transaction in the block.
Cryptographic commitments to the results of DeliverTx, EndBlock, and
Commit are included in the header of the next block.
Tendermint opens three connections to the application to handle the different message
types:
- ``Consensus Connection - InitChain, BeginBlock, DeliverTx, EndBlock, Commit``
- ``Mempool Connection - CheckTx``
- ``Info Connection - Info, SetOption, Query``
The ``Flush`` message is used on every connection, and the ``Echo`` message
is only used for debugging.
Note that messages may be sent concurrently across all connections -
a typical application will thus maintain a distinct state for each
connection. They may be referred to as the ``DeliverTx state``, the
``CheckTx state``, and the ``Commit state`` respectively.
See below for more details on the message types and how they are used.
Echo
^^^^
- **Arguments**:
- ``Message (string)``: A string to echo back
- **Returns**:
- ``Message (string)``: The input string
- **Usage**:
- Echo a string to test an abci client/server implementation
Flush
^^^^^
- **Usage**:
- Signals that messages queued on the client should be flushed to
the server. It is called periodically by the client implementation
to ensure asynchronous requests are actually sent, and is called
immediately to make a synchronous request, which returns when the
Flush response comes back.
Info
^^^^
- **Arguments**:
- ``Version (string)``: The Tendermint version
- **Returns**:
- ``Data (string)``: Some arbitrary information
- ``Version (Version)``: Version information
- ``LastBlockHeight (int64)``: Latest block for which the app has
called Commit
- ``LastBlockAppHash ([]byte)``: Latest result of Commit
- **Usage**:
- Return information about the application state.
- Used to sync Tendermint with the application during a handshake that
happens on startup.
- Tendermint expects ``LastBlockAppHash`` and ``LastBlockHeight`` to be
updated during ``Commit``, ensuring that ``Commit`` is never called twice
for the same block height.
SetOption
^^^^^^^^^
- **Arguments**:
- ``Key (string)``: Key to set
- ``Value (string)``: Value to set for key
- **Returns**:
- ``Code (uint32)``: Response code
- ``Log (string)``: The output of the application's logger. May be non-deterministic.
- ``Info (string)``: Additional information. May be non-deterministic.
- **Usage**:
- Set non-consensus critical application specific options.
- e.g. Key="min-fee", Value="100fermion" could set the minimum fee required for CheckTx
(but not DeliverTx - that would be consensus critical).
InitChain
^^^^^^^^^
- **Arguments**:
- ``Validators ([]Validator)``: Initial genesis validators
- ``AppStateBytes ([]byte)``: Serialized initial application state
- **Usage**:
- Called once upon genesis.
Query
^^^^^
- **Arguments**:
- ``Data ([]byte)``: Raw query bytes. Can be used with or in lieu of
Path.
- ``Path (string)``: Path of request, like an HTTP GET path. Can be
used with or in liue of Data.
- Apps MUST interpret '/store' as a query by key on the underlying
store. The key SHOULD be specified in the Data field.
- Apps SHOULD allow queries over specific types like '/accounts/...'
or '/votes/...'
- ``Height (int64)``: The block height for which you want the query
(default=0 returns data for the latest committed block). Note that
this is the height of the block containing the application's
Merkle root hash, which represents the state as it was after
committing the block at Height-1
- ``Prove (bool)``: Return Merkle proof with response if possible
- **Returns**:
- ``Code (uint32)``: Response code.
- ``Log (string)``: The output of the application's logger. May be non-deterministic.
- ``Info (string)``: Additional information. May be non-deterministic.
- ``Index (int64)``: The index of the key in the tree.
- ``Key ([]byte)``: The key of the matching data.
- ``Value ([]byte)``: The value of the matching data.
- ``Proof ([]byte)``: Proof for the data, if requested.
- ``Height (int64)``: The block height from which data was derived.
Note that this is the height of the block containing the
application's Merkle root hash, which represents the state as it
was after committing the block at Height-1
- **Usage**:
- Query for data from the application at current or past height.
- Optionally return Merkle proof.
BeginBlock
^^^^^^^^^^
- **Arguments**:
- ``Hash ([]byte)``: The block's hash. This can be derived from the
block header.
- ``Header (struct{})``: The block header
- ``AbsentValidators ([]int32)``: List of indices of validators not
included in the LastCommit
- ``ByzantineValidators ([]Evidence)``: List of evidence of
validators that acted maliciously
- **Usage**:
- Signals the beginning of a new block. Called prior to any DeliverTxs.
- The header is expected to at least contain the Height.
- The ``AbsentValidators`` and ``ByzantineValidators`` can be used to
determine rewards and punishments for the validators.
CheckTx
^^^^^^^
- **Arguments**:
- ``Tx ([]byte)``: The request transaction bytes
- **Returns**:
- ``Code (uint32)``: Response code
- ``Data ([]byte)``: Result bytes, if any.
- ``Log (string)``: The output of the application's logger. May be non-deterministic.
- ``Info (string)``: Additional information. May be non-deterministic.
- ``GasWanted (int64)``: Amount of gas request for transaction.
- ``GasUsed (int64)``: Amount of gas consumed by transaction.
- ``Tags ([]cmn.KVPair)``: Key-Value tags for filtering and indexing transactions (eg. by account).
- ``Fee (cmn.KI64Pair)``: Fee paid for the transaction.
- **Usage**: Validate a mempool transaction, prior to broadcasting or
proposing. CheckTx should perform stateful but light-weight checks
of the validity of the transaction (like checking signatures and account balances),
but need not execute in full (like running a smart contract).
Tendermint runs CheckTx and DeliverTx concurrently with eachother,
though on distinct ABCI connections - the mempool connection and the consensus
connection, respectively.
The application should maintain a separate state to support CheckTx.
This state can be reset to the latest committed state during ``Commit``,
where Tendermint ensures the mempool is locked and not sending new ``CheckTx``.
After ``Commit``, the mempool will rerun CheckTx on all remaining
transactions, throwing out any that are no longer valid.
Keys and values in Tags must be UTF-8 encoded strings (e.g. "account.owner": "Bob", "balance": "100.0", "date": "2018-01-02")
DeliverTx
^^^^^^^^^
- **Arguments**:
- ``Tx ([]byte)``: The request transaction bytes.
- **Returns**:
- ``Code (uint32)``: Response code.
- ``Data ([]byte)``: Result bytes, if any.
- ``Log (string)``: The output of the application's logger. May be non-deterministic.
- ``Info (string)``: Additional information. May be non-deterministic.
- ``GasWanted (int64)``: Amount of gas requested for transaction.
- ``GasUsed (int64)``: Amount of gas consumed by transaction.
- ``Tags ([]cmn.KVPair)``: Key-Value tags for filtering and indexing transactions (eg. by account).
- ``Fee (cmn.KI64Pair)``: Fee paid for the transaction.
- **Usage**:
- Deliver a transaction to be executed in full by the application. If the transaction is valid,
returns CodeType.OK.
- Keys and values in Tags must be UTF-8 encoded strings (e.g. "account.owner": "Bob", "balance": "100.0", "time": "2018-01-02T12:30:00Z")
EndBlock
^^^^^^^^
- **Arguments**:
- ``Height (int64)``: Height of the block just executed.
- **Returns**:
- ``ValidatorUpdates ([]Validator)``: Changes to validator set (set
voting power to 0 to remove).
- ``ConsensusParamUpdates (ConsensusParams)``: Changes to
consensus-critical time, size, and other parameters.
- **Usage**:
- Signals the end of a block.
- Called prior to each Commit, after all transactions.
- Validator set and consensus params are updated with the result.
- Validator pubkeys are expected to be go-wire encoded.
Commit
^^^^^^
- **Returns**:
- ``Data ([]byte)``: The Merkle root hash
- **Usage**:
- Persist the application state.
- Return a Merkle root hash of the application state.
- It's critical that all application instances return the same hash. If not,
they will not be able to agree on the next block, because the hash is
included in the next block!

The application should maintain a separate state to support CheckTx.
This state can be reset to the latest committed state during

sending new `CheckTx`. After `Commit`, the mempool will rerun
CheckTx on all remaining transactions, throwing out any that are no
longer valid.

CheckTx for all remaining transactions, throwing out any that are no longer valid.
Then the mempool will unlock and start sending CheckTx again.

- Persist the application state.
- Return a Merkle root hash of the application state.
- It's critical that all application instances return the
same hash. If not, they will not be able to agree on the next
block, because the hash is included in the next block!

Once all processing of the block is complete, Tendermint sends the
Commit request and blocks waiting for a response. While the mempool may
run concurrently with block processing (the BeginBlock, DeliverTxs, and
EndBlock), it is locked for the Commit request so that its state can be
safely reset during Commit. This means the app *MUST NOT* do any
blocking communication with the mempool (ie. broadcast\_tx) during
safely reset during Commit. This means the app _MUST NOT_ do any
blocking communication with the mempool (ie. broadcast_tx) during
Commit, or there will be deadlock. Note also that all remaining

After a few seconds, all the nodes should connect to each other and
start making blocks! For more information, see the Tendermint Networks
section of [the guide to using Tendermint](./using-tendermint.md).

which does the heavy lifting for you. And it gets better.
But wait! Steps 3, 4 and 5 are quite manual. Instead, use the `tendermint testnet` command. By default, running `tendermint testnet` will create all the
required files, but it won't populate the list of persistent peers. It will do
it however if you provide the `--populate-persistent-peers` flag and optional
`--starting-ip-address` flag. Run `tendermint testnet --help` for more details
on the available flags.
Instead of the previously linked script to initialize the files required
for a testnet, we have the `tendermint testnet` command. By default,
running `tendermint testnet` will create all the required files, just
like the script. Of course, you'll still need to manually edit some
fields in the `config.toml`. Alternatively, see the available flags to
auto-populate the `config.toml` with the fields that would otherwise be
passed in via flags when running `tendermint node`. As you might
imagine, this command is useful for manual or automated deployments.
```
tendermint testnet --populate-persistent-peers --starting-ip-address 192.168.0.1

Next, use the `tendermint testnet` command to create four directories of config files (found in `./mytestnet`) and copy each directory to the relevant machine in the cloud, so that each machine has `$HOME/mytestnet/node[0-3]` directory. Then from each machine, run:

## List of modules
Here is the list of modules you may encounter in Tendermint's log and a
little overview what they do.
- `abci-client` As mentioned in [Application Development Guide](./app-development.md), Tendermint acts as an ABCI
client with respect to the application and maintains 3 connections:
mempool, consensus and query. The code used by Tendermint Core can
be found [here](https://github.com/tendermint/tendermint/tree/develop/abci/client).
- `blockchain` Provides storage, pool (a group of peers), and reactor
for both storing and exchanging blocks between peers.
- `consensus` The heart of Tendermint core, which is the
implementation of the consensus algorithm. Includes two
"submodules": `wal` (write-ahead logging) for ensuring data
integrity and `replay` to replay blocks and messages on recovery
from a crash.
- `events` Simple event notification system. The list of events can be
found
[here](https://github.com/tendermint/tendermint/blob/master/types/events.go).
You can subscribe to them by calling `subscribe` RPC method. Refer
to [RPC docs](./specification/rpc.md) for additional information.
- `mempool` Mempool module handles all incoming transactions, whenever
they are coming from peers or the application.
- `p2p` Provides an abstraction around peer-to-peer communication. For
more details, please check out the
[README](https://github.com/tendermint/tendermint/blob/master/p2p/README.md).
- `rpc` [Tendermint's RPC](./specification/rpc.md).
- `rpc-server` RPC server. For implementation details, please read the
[README](https://github.com/tendermint/tendermint/blob/master/rpc/lib/README.md).
- `state` Represents the latest state and execution submodule, which
executes blocks against the application.
- `types` A collection of the publicly exposed types and methods to
work with them.

3. Grant of Patent License. Subject to the terms and conditions of
this License, each Contributor hereby grants to You a perpetual,
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the

modifications, and in Source or Object form, provided that You
meet the following conditions:
(a) You must give any other recipients of the Work or
Derivative Works a copy of this License; and
(b) You must cause any modified files to carry prominent notices
stating that You changed the files; and

excluding those notices that do not pertain to any part of
the Derivative Works; and
(d) If the Work includes a "NOTICE" text file as part of its
distribution, then any Derivative Works that You distribute must

of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.
6. Trademarks. This License does not grant permission to use the trade

agreed to in writing, Licensor provides the Work (and each
Contributor provides its Contributions) on an "AS IS" BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions

PARTICULAR PURPOSE. You are solely responsible for determining the
appropriateness of using or redistributing the Work and assume any
risks associated with Your exercise of permissions under this License.
8. Limitation of Liability. In no event and under no legal theory,
whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.
