Lambda256 supports issuing ERC-721 tokens, non-fungible tokens. An ERC-721 token has a unique value and irreplaceable. With ERC-721 token, businesses can issue a non-fungible token associated with one genuine product, and use it to authenticate and ensure ownership of buyers. By authenticating the product on the blockchain, buyers can trust the quality of product and easily engage in transacting secondhand goods. Ultimately, blockchain networks increase transparency, traceability, and exchangeability. This leads to less distribution of imitated goods and more satisfied buyers.
