Cryptologic coordinated symmetric conditional key release

A method including:

• at network interface circuitry:
• obtaining a peer challenge:
• the peer challenge configured to identify an exchange execution platform for a cryptologically-locked asset transaction, the cryptologically-locked asset transaction configured to, when released, transfer an asset to a leading exchange party;
• the peer challenge configured to release the cryptologically-locked asset transaction, after:
• an exchange key is provided on behalf of the leading exchange party, and
• the cryptologically-locked asset transaction is signed by the exchange execution platform;
• obtaining the cryptologically-locked asset transaction;
• sending a request for the exchange key to the leading exchange party at an address for the leading exchange party;
• and
• obtaining the exchange key to facilitate release of the cryptologically-locked asset transaction, the exchange key originating from the leading exchange party;
• and
• at exchange circuitry, the exchange circuitry including memory and one or more processors, the exchange circuitry in data communication with the network interface circuitry and operating within the exchange execution platform, executing the release of the cryptologically-locked asset transaction by:
• accessing the peer challenge via the network interface circuitry;
• determining the address for the leading exchange party based on the cryptologically-locked asset transaction;
• causing the network interface circuitry to send the request for the exchange key to the leading exchange party;
• responsive to the request, accessing the exchange key via the network interface circuitry;
• verifying the exchange key against the peer challenge;
• and
• after verification of the exchange key, finalizing by:
• facilitating release of the cryptologically-locked asset transaction by signing the cryptologically-locked asset transaction;
• and
• coordinated with authorizing release of the cryptologically-locked asset transaction, symmetrically releasing the exchange key to a reciprocal exchange party.

A product including:

• machine-readable media other than a transitory signal;
• and
• instructions stored on the machine-readable media, the instructions configured to, when executed, cause a machine to:
• at network interface circuitry:
• obtain a peer challenge:
• the peer challenge configured to identify an exchange execution platform for a cryptologically-locked asset transaction, the cryptologically-locked asset transaction configured to, when released, transfer an asset to a leading exchange party;
• the peer challenge configured to release the cryptologically-locked asset transaction, after:
• an exchange key is provided on behalf of the leading exchange party, and
• the cryptologically-locked asset transaction is signed by the exchange execution platform;
• obtain the cryptologically-locked asset transaction;
• send a request for the exchange key to the leading exchange party at an address for the leading exchange party;
• and
• obtain the exchange key to facilitate release of the cryptologically-locked asset transaction, the exchange key originating from the leading exchange party;
• and
• at exchange circuitry, the exchange circuitry including memory and one or more processors, the exchange circuitry in data communication with the network interface circuitry and operating within the exchange execution platform, executing the release of the cryptologically-locked asset transaction by:
• execute the release of the cryptologically-locked asset transaction by:
