Super Trade is an industry public chain based on blockchain technology for traceability and trading of artworks. By putting the entire process of artwork creation and transaction on the chain, it perfectly solves the current problem of title confirmation and circulation in the artwork industry. Specifically, Super Trade uses the Internet of Things technology to record the entire process of artwork creation, and generates a unique identity (NFT) for each artwork based on the principle of cryptographic hash operations, extracts "digital fingerprints" and uploads them to the blockchain In terms of traceability, traceability is true, transparent, and cannot be tampered. Super Trade adopts a decentralized method to select custody nodes, and generates on-chain certificates at the same time as artworks are put into storage for custody. The node accepts the designated artwork, and has rich smart contracts to support financial services such as circulation and mortgage. It has created a new model of IAO (Initial Assets Offering). fluidity.
