etcd3 API: transactions

Can this page be updated to include answer to the question below?

https://etcd.io/docs/v3.5/learning/api/#transaction
> Inside a transaction, there is a compare, success and failure blocks. When a follower receives a transaction, does it evaluate the compare block locally then send success/failure operation to the leader, or is the whole transaction definition is forwarded to the leader and compare block is evaluated on the leader?
