* lite2: check header w/ witnesses only when doing bisection
Closes#4872
We don't need to check witnesses if we're doing backwards hash chain
verification. I also think we don't need to do it when sequential
verification is being used.
* lite2: require 1 witness only when verificationMode=skipping
https://github.com/tendermint/tendermint/pull/4929#pullrequestreview-423256477
we don't need witnesses when performing sequential verification (except
when primary fails)
* proto: move mempool to proto
- changes according to moving the mempool reactor to proto

Closes: #2883
Ethermint currently has to maintain a map height-> block hash on the store (see here) as it needs to expose the eth_getBlockByHash JSON-RPC query for Web3 compatibility. This query is currently not supported by the tendermint RPC client.
## Description
in consensus/state.go, when calulating metrics, retrieve address (ergo, pubkey) once prior to iterating over validatorset to ensure we do not make excessive calls to signer.
Partially closes: #4865
## Description
In https://github.com/tendermint/tendermint/pull/4466 a new type was created (EventAttribute) that replaced KV.Pair. This made the type Pair deadcode, this pr removes that type.
I don't think a changelog entry is needed since it is not being used anymore. But will add a section to the upgrading.md to let users know that it was replaced
Closes: #XXX
## Description
bech32 is only used in the sdk. I moved Bech32 to the sdk and we can remove it here. Don't think this needs to go into a minor release
Closes: #XXX
Fixes#4802. The Go HTTP server has a global panic handler for requests, so it was not as severe as first thought.
This fix can still panic, since we try to send a `500` response - if that happens, the Go HTTP server will terminate the connection. Otherwise, the client will get a 200 response, which we should avoid. I'm sort of torn on whether it's even necessary to include this fix, instead of just letting the HTTP server deal with it.
Closes#4783
It looks like we're validating Commit twice. Also, height and blockID params were coming from the commit, so no need to pass them separately.
This is useful for custom state sync `StateProvider` implementations that need to build new states for bootstrapping the node. It will also be useful when implementing other mechanisms to bootstrap nodes, e.g. #4642 and #3713.
The event loop uses a `select` on multiple channels. However, reading from a closed channel in Go always yields the channel's zero value. The processor and scheduler close their channels when done, and since these channels are always ready to receive, the event loop keeps spinning on them.
This changes `routine.terminate()` to not close the channel, and also removes `stopDemux` and instead uses `events` channel closure to signal event loop termination.
Fixes#4687.
Fixes#828. Adds state sync, as outlined in [ADR-053](https://github.com/tendermint/tendermint/blob/master/docs/architecture/adr-053-state-sync-prototype.md). See related PRs in Cosmos SDK (https://github.com/cosmos/cosmos-sdk/pull/5803) and Gaia (https://github.com/cosmos/gaia/pull/327).
This is split out of the previous PR #4645, and branched off of the ABCI interface in #4704.
* Adds a new P2P reactor which exchanges snapshots with peers, and bootstraps an empty local node from remote snapshots when requested.
* Adds a new configuration section `[statesync]` that enables state sync and configures the light client. Also enables `statesync:info` logging by default.
* Integrates state sync into node startup. Does not support the v2 blockchain reactor, since it needs some reorganization to defer startup.
