When timing out for a view, validators sign the payload sha3-256(TimeoutOpCode, View, HighQCView) with their BLS private key.

When voting on a block, validators sign the payload sha3-256(ViewOpCode, View, BlockHash) with their BLS private key.

IsValidSuperMajorityAggregateQuorumCertificate validates that the aggregate QC is properly formed and signed by a super-majority of validators in the network.

Given a QC and a sorted validator list, this function returns true if the QC contains a valid super-majority of signatures from the validator list for the QC's (View, BlockHash) pair.

ScheduledTask is a thread-safe wrapper around time.Timer that allows for creating tasks that can be scheduled to execute at a later time with pre-specified params.

BlockHash is a 32-byte hash of a block used to uniquely identify a block.

FastHotStuffEventLoop is the public facing interface for the consensus event loop.

Create an alias type of the 32 bit block hash so that the raw [32]byte type isn't ambiguously repeated in the code base.

SignatureOpCode is a way for the FastHotStuffEventLoop to differentiate between different types of BLS signatures.
