Block Proposal

Definition ∞ A block proposal represents a collection of validated transactions aggregated by a network participant, typically a validator or miner, to be added to a blockchain. This proposed block includes a header and the transaction data, awaiting verification by other network participants. If the block meets consensus rules and is accepted, it becomes a new, immutable record on the chain. This process is fundamental to extending the blockchain and confirming transactions.
Context ∞ In proof-of-stake systems, the integrity and fairness of block proposals are subject to ongoing scrutiny, particularly concerning validator incentives and potential centralization. Discussions frequently address strategies to ensure decentralization in block creation and to prevent malicious or self-serving proposals. Future research aims to optimize proposer selection mechanisms and enhance network resilience against various attack vectors.
