Terms & Concepts
  • Block reorganization: A temporary revision of blockchain history when the network accepts a competing valid chain, typically because it has more cumulative proof-of-work.
  • Decentralized consensus: The mechanism through which Bitcoin nodes and miners agree on the valid chain without a central authority.
  • Orphaned blocks: Blocks that were valid when mined but are later dropped after another competing chain is accepted by the network.
