Once selected, the proposer broadcasts its proof of selection for the round (i.e., a cryptographic proof verifiable by the public key of the proposer) to all CNs. Thereafter, the CNs selected as committee for the given round responds to the proposer with their own proofs of selection, notifying the proposer to whom to broadcast the new block to be proposed. The proposer then selects a set of transactions from its transaction pool and creates a block by ordering them. Lastly, the proposer executes consensus with the committee to agree upon and finalize the newly created block. Note that Klaytn plans to continuously improve its consensus algorithm to achieve higher security and efficiency.
