Super Trade is an industry public blockchain for art provenance and trading, based on blockchain technology. By recording the entire process of art creation and transactions on the chain, it perfectly solves the current issues of rights confirmation and circulation in the art industry. Specifically, Super Trade uses IoT technology to document the full creation process of each artwork. Based on cryptographic hash functions, it generates a unique identity token (NFT) for every piece, extracting a "digital fingerprint" that is uploaded onto the blockchain, ensuring authenticity, transparency, and immutability. Super Trade adopts a decentralized approach to select custodial nodes, generating tokens on the chain when physical artworks are stored with custodians. These tokens, which record the GID and redemption agreements, can be redeemed for the designated artwork at any node. They also support various financial services such as circulation and collateral through rich smart contract functionalities. The innovative IAO (Initial Assets Offering) model significantly reduces trust and communication costs between both parties in art transactions, enhancing asset liquidity.
