BLOCKCHAIN-IMPLEMENTED SYSTEMS AND METHODS FOR SECURE ACCESS CONTROL

Resumen de: US2025292243A1

Methods and systems for enabling conditional access to a resource, where the condition is the performance of a task. This task can be executed by one party on behalf of another. The entity controlling access creates a task that includes broadcasting a transaction on the blockchain, with multiple outputs, including a locking-output. Additional transactions ensure access to the resource only upon task completion. Access is achieved by initially broadcasting the resource, conditionally available, then broadcasting the transaction that fulfills the condition. Multi-signatures and a refund mechanism are used to lock access, with multi-signatures spread across transactions. Initial deposit broadcast makes the resource available but locked by a first multi-signature and tied to a refund mechanism. The task and transaction have a locking-output secured by a second multi-signature linked to the refund mechanism. Access requires both multi-signatures of the refund mechanism to be signed and the main transaction to be broadcast.
