The FastSet Whitepaper

The FastSet: Parallel Claim Settlement whitepaper introduces FastSet, a groundbreaking actor-based distributed protocol designed to overcome the scalability limitations of traditional blockchains. Unlike blockchains that rely on global consensus and sequential transaction ordering, FastSet enables massively parallel settlement of independently verifiable claims—ranging from payments to arbitrary program executions—without requiring validator communication. Inspired by the actor model for concurrency, FastSet abandons strong consistency in favor of “weak independence,” allowing validators to process claims in varying orders while still achieving consistent global state replication. This architecture promises high throughput, low latency, and scalable verifiability, making it ideal for next-generation decentralized applications, including AI agents, cross-chain protocols, and verifiable computing systems.
