Proposer Commitment

Definition ∞ Proposer commitment refers to the assurance or pledge made by a block proposer in a blockchain network to include specific transactions or adhere to certain rules when constructing a block. This commitment aims to increase transparency and fairness in the block production process. It often involves cryptographically binding the proposer to their declared intentions.
Context ∞ In proof-of-stake systems, particularly with the rise of builder-proposer separation and Maximal Extractable Value (MEV) considerations, proposer commitment is a significant topic. Mechanisms like proposer-builder separation (PBS) are designed to enforce these commitments, preventing malicious reordering or censorship of transactions by block producers. This concept is vital for maintaining the integrity and decentralization of the network.
