Block agreement is the process by which a distributed network of nodes reaches a consensus on the validity and order of transactions within a new block. This agreement ensures that all honest participants accept the same block as the next legitimate addition to the blockchain. It is a fundamental step in maintaining the integrity and immutability of a distributed ledger. Without robust block agreement, the blockchain could fork or become inconsistent.
Context
In cryptocurrency networks, block agreement is achieved through various consensus mechanisms, such as Proof of Work or Proof of Stake. The speed and reliability of block agreement directly influence transaction finality and the network’s resistance to attacks. News concerning network upgrades often highlights improvements or changes to the block agreement process to enhance performance or security.
