Method for multi-party blockchain transaction authorization based on real-time due diligence

A method comprising:

• receiving a first message from a first agent, the first message comprising a request to transfer a first virtual asset to a first recipient identifier, associated with a second agent, from a sender identifier associated with a sender blockchain address;
• for the first agent:
• identifying a first subset of agents affiliated with the first agent;
• accessing a first set of policies implemented by the first agent;
• accessing a third set of policies implemented by the first subset of agents;
• accessing a first set of transaction characteristics of transactions associated with the first agent;
• accessing a third set of transaction characteristics of transactions associated with the first subset of agents;
• characterizing a first compliance state of the first agent based on the first set of policies and the third set of policies;
• accessing a set of transactions associated with the first agent during a target time interval;
• extracting the first set of transaction characteristics from the set of transactions;
• calculating a proportion of transactions, in the set of transactions, occurring during the target time interval based on the set of transaction characteristics;
• and
• calculating a first risk score in response to the proportion of transactions exceeding a threshold proportion of transactions;
• characterizing a first risk profile, comprising the first risk score, of the first agent based on:
• the first set of transaction characteristics;
• and
• the third set of transaction characteristics;
• generating a second message representing:
• the request;
• the sender blockchain address;
• the first compliance state of the first agent;
• and
• the first risk profile of the first agent;
• transmitting the second message to the second agent;
• receiving confirmation from the second agent to proceed with transfer of the first virtual asset based on:
• the first compliance state fulfilling a first compliance state requirement;
• and
• the first risk profile fulfilling a first risk profile requirement;
• for the second agent:
• identifying a second subset of agents affiliated with the second agent;
• accessing a second set of policies implemented by the second agent;
• accessing a fourth set of policies implemented by the second subset of agents;
• accessing a second set of transaction characteristics of transactions associated with the second agent;
• accessing a fourth set of transaction characteristics of transactions associated with the second subset of agents;
• characterizing a second compliance state of the second agent based on the second set of policies and the fourth set of policies;
• and
• characterizing a second risk profile of the second agent based on the second set of transaction characteristics and the fourth set of transaction characteristics, the second risk profile including a second risk score;
• generating a third message representing:
• the request;
• an authorization of transfer of the first virtual asset by the second agent;
• the second compliance state of the second agent;
• and
• the second risk profile of the second agent;
• transmitting the third message to the first agent;
• and
• in response to receiving confirmation from the first agent to proceed with transfer of the first virtual asset based on based on the second compliance state and the fourth compliance state fulfilling a second compliance state requirement and the second risk profile and the fourth risk profile fulfilling a second risk profile requirement
• retrieving a first recipient blockchain address associated with the first recipient identifier;
• and
• transmitting the first recipient blockchain address to the first agent to enable transfer of the first virtual asset from the sender blockchain address to the first recipient blockchain address.
