Sub-Second Block Times

Architecture

Sub-second block times represent a fundamental shift in distributed ledger technology, aiming to enhance transaction throughput and reduce latency compared to traditional blockchain systems. This acceleration necessitates architectural innovations, often involving layer-2 scaling solutions or modifications to consensus mechanisms like Practical Byzantine Fault Tolerance variants. The design implications extend to network bandwidth requirements and data propagation strategies, demanding optimized data structures and efficient communication protocols. Consequently, the architecture must balance speed with security and decentralization, preventing centralization risks inherent in prioritizing velocity.
