Coin Cloud Chain is established using the latest Litecoin technology, subverting the traditional trading model. Coin Cloud Chain reviews and stores the information of each link of the product to realize information identification. At the same time, with the help of the "decentralization" feature of the blockchain, Coin Cloud Chain has established a technology-based trust system for the trading platform, which can establish a trust relationship between both parties without the participation of a third party. Therefore, in the Coin Cloud Chain platform, because the platform is non-tamperable and traceable, participants have absolute trust in the transaction fair mechanism, which ensures the normal operation of the transaction.
