Candidate Blocks

Published on August 30th, 2021

Candidate blocks are blocks created by miners as part of a proof-of-work consensus process. A miner will receive a block reward when it produces a candidate block with a valid block hash and broadcasts this block to the network’s nodes, who verify the hash’s authenticity. In this manner, every (non-genesis) block on a blockchain begins its life as one of many pre-validated candidate blocks.
