The block proposer is a validator node responsible for creating and proposing a new block to the blockchain network in a Proof-of-Stake consensus mechanism. This entity aggregates transactions from the mempool, or from a builder in a separated proposer-builder architecture, and constructs the final block structure. The proposer’s primary function is to ensure the integrity and chronological order of transactions before they are attested to by other validators.
Incentive
Proposers receive a base reward for successfully proposing a valid block, along with transaction fees and any Maximal Extractable Value (MEV) captured within the block. This economic incentive aligns the proposer’s interests with network security and efficient transaction processing. The profitability of this role is directly tied to the volume of network activity and the efficiency of MEV extraction strategies.
Mechanism
The selection of a block proposer is typically determined by a random process weighted by the amount of stake held by each validator. In advanced systems like Ethereum’s post-Merge architecture, the proposer role is separated from the block building function, allowing the proposer to select the most profitable block from a set of options provided by external builders. This separation aims to mitigate centralization risks associated with MEV extraction.
