Definition ∞ A decentralized proposer is an entity or mechanism in a blockchain network responsible for suggesting new blocks or transaction orderings in a non-centralized manner. This role is distributed among many participants, preventing any single point of control over block creation. It contrasts with centralized systems where a sole authority performs this function.
Context ∞ The selection and operation of decentralized proposers are critical for maintaining censorship resistance and security in proof-of-stake blockchains and rollup architectures. Discussions often revolve around fair proposer selection algorithms and mitigating potential centralization risks associated with large staking pools. Advances in decentralized proposer mechanisms aim to enhance network robustness and equity.
