摘要： Multi-party consent to performance of an action is securely registered by receiving from at least one consent requesting entity (CRE) a consent action request (CAR), which is matched with a consent policy. The policy may specify a plurality of consent voting entities (CVE), and direct confirmation of registration of an identity of each CVE in a blockchain. A consent request (CR) may then be issued to the CVEs. Consent request responses (CRRs) from the CVEs are then compared with at least one condition in the consent policy. A representation of a state of the CRRs is relative to the consent policy is registered in the blockchain. If the policy condition(s) is satisfied, a subject entity may be signaled to perform the action corresponding to the CAR, and a state indication of performance of the action may also be registered in the blockchain.
