HyperCycle is a new Layer 0++ blockchain architecture designed for high-speed and inexpensive on-chain execution of microservices, particularly (but not limited to) those related to AI. This article provides an overview of the HyperCycle design, which leverages the TODA/IP ledgerless blockchain, the TODA asset model, and SingularityNET’s Proof of Reputation system. Also discussed will be the potential applications of HyperCycle, such as swarm AI, rating and reward in media networks, decentralized payments and computer processing, and public/private chain interoperability.
