### Overview of Proposed Change
### Overview of Change
This ADR proposes consolidating the timeout parameters and migrating them from the
node-local `config.toml` file into the network-global consensus parameters.
The consensus parameters are the same across all validators on the network.
We will consolidate the timeout parameters and migrate them from the node-local
`config.toml` file into the network-global consensus parameters.
A sane default will be provided by Tendermint for each of these parameters and
networks will be able to update the parameters as they see fit. Local updates
to these parameters will no longer be possible; instead, the application will control
updating the parameters. Applications using the Cosmos SDK will be automatically be
able to change the values of these consensus parameters [via a governance proposal][cosmos-sdk-consensus-params].
This ADR also proposes consolidating the 8 timeout parameters into 6. These
6 parameters would be as follows:
The 8 timeout parameters will be consolidated down to 6. These will be as follows:
* `TimeoutPropose`
* Same as current `TimeoutPropose`.
* `TimeoutProposeDelta`
* Same as current `TimeoutProposeDelta`.
* `TimeoutVote`
* Parameter that governs how long validators wait for votes in both the prevote
and precommit phase of the consensus algorithm. This parameter will subsume
* How long validators wait for votes in both the prevote
and precommit phase of the consensus algorithm. This parameter subsumes
the current `TimeoutPrevote` and `TimeoutPrecommit` parameters.
* `TimeoutVoteDelta`
* Parameter that governs how much the `TimeoutVote` will grow each successive round.
This parameter will subsume the current `TimeoutPrevoteDelta` and `TimeoutPrecommitDelta`
* How much the `TimeoutVote` will grow each successive round.
This parameter subsumes the current `TimeoutPrevoteDelta` and `TimeoutPrecommitDelta`
parameters.
* `TimeoutCommit`
* Same as current `TimeoutCommit`.
* `SkipTimeoutCommit`
* Same as current `SkipTimeoutCommit`.
A safe default will be provided by Tendermint for each of these parameters and
networks will be able to update the parameters as they see fit. Local updates
to these parameters will no longer be possible; instead, the application will control
updating the parameters. Applications using the Cosmos SDK will be automatically be
able to change the values of these consensus parameters [via a governance proposal][cosmos-sdk-consensus-params].
This change is low risk. While these values may be configured, many running chains
do not change these parameters from their default values. For example, initializing
a node on Osmosis, Terra, and the Cosmos Hub using the their `init` command produces
