Block Proposer

Definition ∞ A block proposer is an entity responsible for gathering a set of transactions and constructing a new block to be added to a blockchain. In proof-of-stake systems, this role is assigned to a validator selected through a specific protocol mechanism. The proposer then broadcasts this proposed block to the network for verification by other validators. Successful block proposals result in rewards for the proposer.
Context ∞ The role of block proposers frequently appears in discussions surrounding blockchain consensus mechanisms, particularly in proof-of-stake networks. News often covers advancements in proposer selection algorithms aimed at enhancing decentralization and preventing censorship. The fairness and efficiency of block proposal processes are critical for the security and performance of many digital asset platforms, influencing their overall network health and transaction processing.
