Abstract
An example operation may include one or more of storing a list of unavailable blockchain peers that cannot be a lead peer of a blockchain consensus protocol, generating a pre-prepare message comprising a new block of a blockchain, appending commit messages received during a commit stage of a previous block to the blockchain, to the pre-prepare message, where the commit messages identify an unavailable blockchain peer from the list that is now available, and broadcasting the pre-prepare message with the new block and the appended commit messages to a plurality of blockchain peers.
