Referring also to fig. 2-8, the instructions stored by the trading platform 100 may be loaded and executed by the processor 120 to implement an online trading method based on consumption commitments.
Specifically, the online transaction method based on the consumption commitment can comprise the following steps.
S101, receiving a transaction request sent by a buyer in a network mall. I.e. the buyer purchases the order in the network mall.
And S102, receiving transaction information. The transaction information may include buyer information, seller information, commodity price and payment conditions, for example, the transaction information may include account information of the buyer in the network mall, account information of the seller in the network mall, price and payment conditions of the target commodity to assist in completing the transaction.
Specifically, the buyer may send a transaction request to the seller, which may include buyer information, targeted merchandise information intended for purchase. The seller confirms whether the target commodity can be sold according to the transaction request of the buyer.
If the intention to purchase and sell is reached, the transaction platform 100 may collect transaction information, including buyer information, target commodity information, seller information, and order information.
The collected transaction information may be stored into blockchain based distributed network 200.
S103, the buyer confirms the transaction information, makes a consumption commitment and signs an intelligent contract based on the consumption commitment.
For example, in an implementation, the intelligent contracts may be blockchain intelligent contracts. The blockchain smart contracts may include the sum of the commodity labels and the quantity, the payment method, and the delivery method. It is to be understood that in other embodiments, the intelligent contract may be other forms of intelligent contracts, as long as the intelligent contract can satisfy the requirements of being verified and being able to be authenticated.
In a preferred embodiment, in step S103, the buyer confirms the transaction information, makes a consumption commitment and signs a smart contract based on the consumption commitment, the signing of the smart contract may specifically include the following steps.
And S1031, generating a block chain intelligent contract according to the transaction information and a predetermined rule.
