Background
The general digital asset off-site trading system adopts a centralized mode, an off-site trading platform is used as a third party of guarantee, a total digital asset management account is provided as a guarantee account, a user A with trading demand firstly needs to store own digital assets into the guarantee account, and the platform side makes a credit account for the stored assets and records the credit account under the name of the user A. Then, the user A initiates a sale advertisement in the digital asset off-site trading system, and distributes part or all of the deposited digital assets on the trading system at a proper price. If user B sees the sell advertisement, a purchase may be initiated as deemed appropriate. After the purchase operation is initiated, the user B needs to pay own legal money to the user A through online transfer. After receiving the account transfer of the user B, the user A confirms the collection of the money on the transaction system and informs the system to release the digital assets with the corresponding quantity to the user B. After receiving the instruction, the transaction platform makes a credit account for a expenditure for the user A, makes a credit account for a income for the user B, and can collect a certain proportion of fees at the same time, and then the user B can extract the purchased digital assets into the digital wallet of the user B, and the transaction is completed. The main defects of the prior art are as follows: 1. the whole transaction system is centralized and has no characteristic of being not tampered.
