Commit to Generation Transaction

The Commit to Generation transaction is created automatically by a block generator node to commit to a generation signature for a future period as part of the deterministic finality mechanism.

The Commit to Generation transaction type is enabled by feature #25 "Deterministic Finality".

A block generator must send a Commit to Generation transaction to join the next generation period.
