The following specifically exemplifies embodiments of the present invention
In an embodiment of the present invention, implementing decentralized content interaction comprises: the initiating user A wants to buy 1 bit coin by using 45000 RMB in the exchange 1, and the target user B wants to sell 1 bit coin in the exchange 2, with the selling price of 5000 Hongyuan. Since currently the two legal currencies are not supported on a single digital exchange, and users a and B are on different exchanges, the content interaction of initiating user a and target user B is achieved and satisfied through the mediation of intermediary user C, which is implemented with decentralization.
Figure 2 is a system overview block diagram of decentralized asset exchange, according to an embodiment of the present invention. As shown in fig. 2, a common user a is in an exchange 1 as an initiating node, a common user B is in an exchange 2 as a target node, and the two parties perform identity authentication, content interaction, transaction credential generation, and the like through an intermediate user node and store the authentication, the content interaction, the transaction credential, and the like in a blockchain.
Fig. 3 is a flow diagram of a method 300 of decentralized asset exchange, according to an embodiment of the invention. As shown in fig. 3, in an embodiment of the present invention, implementing decentralized asset exchange begins at step 301, where an initiating user a creates a purchase requisition at exchange 1 and issues at step 301. Wherein, the purchase application includes: the name of the acquired content is bitcoin, the number of the acquired content is 1, the purchase price is 45000 RMB, and the valid period of the application is 3 days.
The purchase request can also be added with remark information, for example, the exchange of the remark receiving user is exchange 2, the number of bitcoins owned by the receiving user is more than 1, the commission charge and the like.
For the purchase application meeting the requirement, initiating a user A to complete content interaction in a matching way; for the unsatisfactory purchase request, the initiating user a needs to cancel or reissue the request after modification.
At step 302, the exchange 1 where the initiating user A is located locks the 45000 RMB asset in the initiating user A account according to the purchase request until the transaction is completed or cancelled.
After the purchase fund in the account of the initiating user A is locked, if the transaction is completed within the specified time, the provided currency is sent to the intermediate user and is not returned to the initiating user; if the transaction is not completed, the transaction is cancelled, and the cancelled transaction can be reissued and suspended.
At step 303, target user B creates a sale application at exchange 2 and issues it. Wherein the sale application comprises: the name of the push content is bitcoin, the number is 1, the selling price is 50000 port coin, and the valid period of the application is 3 days.
Remark information can be added in the sale application, for example, the exchange of the remark receiving user is the exchange 1, and the asset owned by the receiving user is larger than 50000 port currency.
For the purchase application meeting the requirement, initiating a user B to complete content interaction in a matching way; for an unsatisfactory purchase request, the initiating user B needs to revoke or revise and reissue the purchase request. In step 304, the exchange 2 where the target user B is located locks 1 bitcoin in the account of the target user B according to the sale application until the transaction is completed or cancelled.
After the sale assets in the account of the initiating user B are locked, if the transaction is completed within the specified time, the provided sale assets are sent to the intermediate user and are not returned to the initiating user; if the transaction is not completed, the transaction is cancelled, and the cancelled transaction can be reissued and suspended.
In step 305, it is determined that the purchase request and the sale request meet a preset matching strategy, content interaction is performed, and an interaction certificate is generated and stored in a block chain. Wherein the intermediary user has an account with both exchange 1 and exchange 2, and can satisfy both requests.
Fig. 4 is a flow diagram of a method 400 of content interaction according to an embodiment of the invention. As shown in fig. 4, the method specifically includes the following steps:
step 401, determining that the purchase request and the push request satisfy a preset matching strategy. Specifically, the method comprises the following steps: determining that the name of the acquired content and the number of the acquired content in the purchase application are respectively consistent with the name of the pushed content of the sale application and the number of the pushed content, wherein the number of the pushed service resources meets the requirement of acquiring the number of the service resources, and the acquisition request and the pushing request are both in an effective state, and determining that the acquisition request and the pushing request meet a preset matching strategy.
At step 402, the intermediary user agrees through exchange 1 and exchange 2. Therefore, the node has safety, openness and reliability, and can complete the registration of the intermediate node.
In step 403, the intermediary user confirms the suspension order of the initiating user at the exchange 1, locks the suspension order, receives 45000CNY of the initiating user, generates the first interaction certificate, and stores the first interaction certificate in the blockchain. At this point, the originating user's hang ticket will no longer be acknowledged by other users, which acknowledgement requires that the BTC balance of the intermediate user be sufficient, such as greater than 1 BTC.
The confirmed bill-hanging must be completed within the specified time, otherwise the bill-hanging will be hung again, the intermediate user will be punished, and the corresponding interactive certificate is generated after the bill-hanging transaction is completed, and the interactive certificate is the transaction record which is stored in the block chain and can not be tampered.
At step 404, the intermediary user purchases 1BTC from the target user at exchange 2 using 50000HKD and confirms the user hang-up information at exchange 1 in response to the target user selling the application notes.
Step 405, the target user receives 1BTC sent by the intermediate user, confirms that the remark requirement is met, completes the transaction in a matching way, receives 50000HKD, sends 1BTC to the intermediate user, generates a second interactive certificate and stores the second interactive certificate in the block chain; and after the transaction is completed, the corresponding second interaction certificate generated is stored in the block chain to become a transaction record which can not be tampered, so that the validity of the transaction process is ensured.
Step 406, the intermediary user receives 1BTC, sends 1BTC to the initiating user at the exchange 1, and generates a third interaction credential to store in the blockchain.
Step 407, configuring the first transaction voucher, the second transaction voucher, and the third transaction voucher as a combined interaction voucher, and storing the combined interaction voucher in the block chain to complete content interaction. The method comprises the steps that an interactive certificate of an initiating user and a target user subjected to joint signature is stored in a blockchain network through an intermediate user to serve as a transaction record, the interactive certificate which cannot be tampered (the tampering needs high-amount workload certification and cannot be achieved) is permanently stored in the blockchain network to ensure the legal transaction record, after the common identification is achieved in the blockchain network, account values of the initiating user and the target user are updated, and the exchange transaction is completed.
