Example 2:
example 2 is a preferred example of example 1.
When a share right transaction user account is generated, a user private key is encrypted by using a symmetric key generated according to user related information and then uploaded to a server, and registration and permission binding of the user account are carried out.
The block chain-based batch settlement method provided by the invention comprises the following steps:
the method comprises the following steps: an intelligent contract for checking clearing is pre-deployed in a block chain, and the set rule is as follows: the clearing initiator submits a batch of transactions to the intelligent contract and submits corresponding funds for clearing. The intelligent contract needs to verify that each transaction has signature information of both the bank and the payee, and if the rule is confirmed to pass, the fund distribution and confirmation are completed.
Step two: when the batch clearing service occurs, a temporary network channel is created outside the block chain. After the liquidation originator a signs a batch of transactions to be linked, the bill for these transactions is sent to the payee B, C, D for confirmation via a temporary network channel, as shown in fig. 1.
Step three: after receiving the bill, the payee B, C, D confirms the bill and signs the transaction, at this time B, C, D stores a bill b, c, d with the signature of both parties, and sends it to a through the network channel.
Step four: after receiving the batch of bills b, c and d with the signatures of both parties, the A sends the bills and the funds to the intelligent contract for clearing.
Step five: after receiving the bills b, c and d, the intelligent contract starts an examination stage, verifies whether the bills are signed by both parties, and reserves a complaint period of 6 blocks. During the complaint period, if B, C, D submitted a different intelligent contract than that submitted by A and possessed the bill data signed by both parties, then the liquidation is not performed.
Step six: after the complaint period, the intelligent contract will automatically transfer funds.
