Epoch transition happens when someone calls and the current block is epochLength blocks more since last transitioned block.
In beginEpochTransition()
An EpochEnded event is emitted and currentEpoch increases by 1.
by sealed it means that the hash chain is hashed again with 1, e.g.,
hash(1, originalHashChain)
if an epoch key received no attestation, it's hash chain would be hash(1, 0)
there's only one epoch tree for every epoch.
After the EpochEnded event is emitted, all epoch keys attested during this epoch will have their sealed
After hash chain of the epoch keys are sealed, these epoch keys and their hash chain will be inserted into the of this epoch
There will be a new for each epoch.
And after epoch transition, user needs to perform to transition his user state into the latest epoch
currentEpoch is increased by one.
