NFT Enforcement Control System

A computer-implemented method of enforcing conditional transfer of digital assets, the computer-implemented method comprising:

• implementing, upon a blockchain network, a cross-chain clearinghouse control system configured to:
• (i) approve a transfer of a digital asset from a first entity to a second entity in response to the transfer satisfying a preset rule encoded in the digital asset or (ii) disapprove the transfer in response to the transfer not satisfying the rule, the cross-chain clearinghouse control system being embedded on a cryptoprocessor of at least one of multiple nodes of the blockchain network;
• wherein one of the first and second entities is a digital wallet implemented upon the blockchain network, and an other of the first and second entities is implemented apart from the blockchain network.

A non-transitory computer program product for enforcing conditional transfer of digital assets, the non-transitory computer program product comprising a computer-readable medium with computer code instructions stored thereon, the computer code instructions being configured, when executed by a processor, to cause the processor to:

• implement, upon a blockchain network, a cross-chain clearinghouse control system configured to:
• (i) approve a transfer of a digital asset from a first entity to a second entity in response to the transfer satisfying a preset rule encoded in the digital asset or (ii) disapprove the transfer in response to the transfer not satisfying the rule, the cross-chain clearinghouse control system being embedded on a cryptoprocessor of at least one of multiple nodes of the blockchain network;
• wherein one of the first and second entities is a digital wallet implemented upon the blockchain network, and an other of the first and second entities is implemented apart from the blockchain network.
