Compact Block Protocol

Definition ∞ A Compact Block Protocol is a method used in blockchain networks to reduce the amount of data transmitted between nodes when new blocks are propagated. Instead of sending full block data, only a small set of transaction identifiers and a block header are initially sent. This protocol significantly improves network efficiency by minimizing bandwidth usage and accelerating block relay times. It allows nodes to reconstruct new blocks more quickly using transactions they have already seen.
Context ∞ The adoption of the Compact Block Protocol has been a significant step in optimizing blockchain network synchronization and reducing the latency associated with block propagation. This advancement helps to mitigate the risk of stale blocks and contributes to a more robust and responsive network operation. Continued refinements to block propagation mechanisms are crucial for scaling blockchain technology and accommodating increasing transaction volumes.
