System and method for high performance providing fresh NFT metadata

A system for caching NFT blockchain metadata for fast retrieval and automatically and adaptively verifying the metadata, the system comprising:

• a processor;
• and
• a memory communicatively coupled to the processor, the memory storing instructions executable by the processor to perform a method comprising:
• initializing a metadata cache from the metadata in a mirror blockchain that is a copy of an NFT blockchain;
• updating periodically the mirror blockchain with new blocks from the NFT blockchain;
• processing the new blocks by extracting all metadata transaction events incorporating NFT methods that implement metadata modifications;
• updating the metadata cache with the metadata modifications;
• selecting an NFT group, the NFT group having an adaptively assigned time-to-live;
• receiving a user computer request for metadata;
• accessing the metadata from the metadata cache;
• generating a user response with the metadata and a freshness indication;
• and
• verifying the metadata cache against the NFT blockchain metadata, upon the NFT group's time-to-live expiring, the verifying comprising:
• updating the time-to-live for the NFT group using a learning algorithm based on discrepancies between the cached metadata and the NFT blockchain;
• and
• updating the metadata cache with the NFT group's associated metadata from the NFT blockchain.

A non-transitory computer readable medium having embodied thereon instructions, which when executed by a processor, perform steps of a method for caching NFT blockchain metadata for fast retrieval and automatically and adaptively verifying the metadata, the method comprising:

• initializing a metadata cache from the metadata in a mirror blockchain that is a copy of an NFT blockchain;
• updating periodically the mirror blockchain with new blocks from the NFT blockchain;
• processing the new blocks by extracting all metadata transaction events incorporating NFT methods that implement metadata modifications;
• updating the metadata cache with the metadata modifications;
• selecting an NFT group, the NFT group having an adaptively assigned time-to-live;
