Asset metadata oracle service for facilitating digital asset trading

A system comprising:

• a first one or more electronic devices to implement an asset management platform, wherein the asset management platform includes instructions that upon execution by one or more first processors cause the asset management platform to:
• store a first certificate of ownership corresponding to a physical item, wherein the first certificate of ownership includes an identifier of a first owner of the physical item, and wherein the first certificate of ownership is a composite certificate of ownership that references a plurality of certificates of ownership;
• store, on a decentralized ledger, a first non-fungible token (NFT) corresponding to the physical item, wherein the first NFT includes an identifier of the first certificate of ownership, wherein the first NFT is a composite asset NFT that references a plurality of NFTs, and wherein the composite asset NFT includes a reference to the composite certificate of ownership;
• invoke execution of an asset metadata service to obtain data indicating a status of the physical item;
• identify, by the asset management platform, a second NFT indicating a transfer of ownership of the physical item from the first owner to a second owner;
• revoke, by the asset management platform, the first certificate of ownership;
• and
• store a second certificate of ownership including an identifier of the second owner;
• and
• a second one or more electronic devices to implement the asset metadata service, wherein the asset metadata service includes instructions that upon execution by one or more second processors cause the asset metadata service to:
• obtain, from a first data store managed by the asset management platform, the data indicating the status of the physical item;
• and
• store, on the decentralized ledger, a data record indicating the status of the physical item.

A non-transitory computer-readable storage medium storing instructions which, when executed by one or more processors, cause performance of operations including:

• storing, by an asset management platform, a first certificate of ownership corresponding to a physical item, wherein the first certificate of ownership includes an identifier of a first owner of the physical item, and wherein the first certificate of ownership is a composite certificate of ownership that references a plurality of certificates of ownership;
• storing, on a decentralized ledger, a first non-fungible token (NFT) corresponding to the physical item, wherein the first NFT includes an identifier of the first certificate of ownership, wherein the first NFT is a composite asset NFT that references a plurality of NFTs, and wherein the composite asset NFT includes a reference to the composite certificate of ownership;
• invoking execution of an asset metadata service, wherein execution of the asset metadata service includes:
• obtaining, from a first data store managed by the asset management platform, data indicating a status of the physical item, and
• storing, on the decentralized ledger, a data record indicating the status of the physical item;
• identifying, by the asset management platform, a second NFT indicating a transfer of ownership of the physical item from the first owner to a second owner;
• revoking, by the asset management platform, the first certificate of ownership;
• and
• storing a second certificate of ownership including an identifier of the second owner.
