# Consensus
VERY WIP
The goal of this RFC is to define the consensus algorithm used in solana. This proposal covers a Proof of Stake algorithm that leverages Proof of History. PoH is a permissionless clock for blockchain that is available before consensus. This PoS approach leverages PoH to make strong assumptions about time between partitions.
## Version
@ -112,3 +114,9 @@ Validators should select the first branch to reach finality, or the highest rank
4. M validators observe 10% of the vote pool, finality is not reached
5. M and K re-connect.
6. M validators cancel their votes on K which are below K's `PoH count`
### Leader Timeout
1. Next rank node observes a timeout.
2. Nodes receiving both PoH streams pick the higher rank node.
3. 2, causes a partition, since nodes can only vote for 1 leader.
4. Partition is resolved just like in the [Small Partition](#small-parition)
