Definition
Block proposal is a consensus mechanism step in which a designated participant assembles and presents a candidate block to be considered for addition to a blockchain. A validator or node constructs this block from pending transactions and associated metadata, then submits it to the network’s consensus process, where other participants evaluate it before it can progress toward finality as an accepted block.
In Simple Terms
Block proposal is the moment when a chosen participant suggests the next block to be added to a blockchain. They gather pending transactions into a block and present it to the rest of the network, which then decides whether to accept that block as the next official part of the chain.
Context and Usage
The term block proposal is commonly used when describing how blocks are created and selected within a blockchain’s consensus process. It appears in protocol specifications, validator documentation, and discussions about security, fairness, and performance of block production. Block proposal is closely tied to how nodes coordinate, how validators are selected, and how the system advances from one block to the next.
