Resumen de: US20260252553A1
In a blockchain system in which a network with a hierarchical structure is formed by a plurality of nodes, a node belonging to a first group of a first layer different from a lowest layer manages a first ledger including transaction data related to a transaction in the first group and performs ledger locking to not update the first ledger during a lock period after the first ledger is updated. If a second ledger managed by a second group in a second layer lower than the first layer has been updated within the lock period when the lock period ends, the node updates the first ledger to include, in the first ledger, ledger information related to the updated second ledger.

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.
