Block certification confirms the validity and authenticity of a data block on a blockchain network. This process ensures that a block adheres to the protocol rules and contains legitimate transactions. It is a critical step before a new block is added to the chain. Verification by network participants maintains the integrity of the distributed ledger.
Context
Block certification is a fundamental concept for understanding blockchain security and the reliability of transaction finality. News regarding network upgrades or consensus mechanism changes often relates to how blocks are certified. Issues with certification can signal network vulnerabilities or disruptions in transaction processing.
Mysticeti-C, a new DAG-BFT, achieves the theoretical three-round latency lower bound by eliminating block certification, unifying high throughput with instant finality.
Introducing Mysticeti-C, a BFT protocol using uncertified DAGs and a novel commit rule to achieve the theoretical 3-round message latency limit, enabling sub-second finality.
