Abstract
Systems and methods for fast and efficient retrieval of NFT ownership information are provided. An exemplary method includes initializing a mirror blockchain by making a copy of an NFT blockchain; initializing an ownership transaction table and an NFT ledger from a mirror NFT blockchain by processing the mirror blockchain from a beginning block to an end block; periodically update the mirror blockchain with new blocks from an NFT blockchain thereby forming a new end block; processing ownership transaction events that modify NFT ownership in the new blocks up to a fixed offset from the new end block; updating the ownership transaction table; updating the NFT ledger; receiving a request for all NFTs owned by a crypto-wallet address; generating a response with the NFTs owned by the crypto-wallet address from the NFT ledger; selecting an NFT group; and verifying the NFT ledger against the NFT blockchain ownership.
