Resumen de: WO2026178261A1
Systems and methods for implementing a C3N smart contract enabled blockchain platform. The platform employs a Proof-of-Reputation (PoR) consensus mechanism in which validator nodes are selected based on a C3N Score — a multi-dimensional trust score comprising a weighted composite of eight sub-scores drawn from performance, opinion, and reputation categories — stored on a distributed ledger not controllable by any single entity. The platform reduces the time and cost of building custom cryptocurrency blockchains: a business inputs its rules using the C3N Integrated Development Environment (IDE) or Command Line Interface (CLI), and the platform generates concrete smart contract implementations of pre-fabricated blockchain interfaces automatically. Network routing is conditioned on trust scores, such that only nodes meeting a minimum score threshold participate in routing and consensus.
