On Refinable you now have the NFT history. Each item on Refinable NFT is assigned a unique serial number. Whenever there is a change of ownership (i.e. when a successful purchase takes place), the unique user ID of the current owner and the item’s serial number will be recorded on the BscScan and IFPS.
BscScan is a block explorer and analytics platform for the Binance Smart Chain, and Defistation is a leaderboard and analytics tool for DeFi projects built on top of BSC.
IPFS is a peer-to-peer hypermedia protocol designed to store media content in a decentralized way. As the media file related to NFTs cannot be stored directly on the blockchain, IPFS can store all that data.
