SYSTEM AND METHOD FOR OFFLINE PAYMENT ON A BLOCKCHAIN

Resumen de: WO2026005597A1

Computer-implemented methods and a system are presented for offline payments between nodes. The method includes setting up a vouching agreement between a first and a second node and locking a vouched amount of tokens at the first node for use by the second node. An offline transaction is performed between the second and a third node, wherein the offline transaction exceeds a second amount of tokens available to the second node. While offline, the second node uses the vouched amount to perform the offline transaction with the third node. When online again, the second node reconciles the vouched amount with the first node. If the second node does not pay back the vouched amount to the first node, a reputation score of the second node is decreased. If the second node pays back the vouched amount to the first node, reputation scores of the first and the second node are increased.
