Abstract

The invention discloses a cross-chain transaction method based on multiple signatures. The cross-chain transaction method is characterized by comprising the following steps that (1) an asset account based on multiple signatures is created on an alliance block chain; (2) the user performs cross-chain asset buying and selling operation on a transaction quotation interface; (3) after the buyer and the seller of the transaction reach a consensus, the transaction matching system verifies the consensus and then sends the consensus to the cross-chain transaction system; (4) the cross-chain transaction system performs secondary verification on the transaction information, then signs the transaction to complete multiple signature operations, and finally sends the transaction information to the corresponding block chain for consensus; (5) when an abnormal transaction occurs, the cross-chain transaction system sends transaction information again for the failed transaction of the two parties, andfor the failed transaction of the single party, the alliance chain identifies the abnormal transaction and freezes the additional profit account; the additional profit-gaining user can select reversetransaction or resend failed transaction information, thereby recovering the frozen account quota.

Description

technical field

[0001] The invention relates to the application field of block chain technology, in particular to a block chain cross-chain transaction method based on multi-signature technology. Background technique

[0002] At present, the user's asset conversion on different blockchains is generally completed through a centralized exchange, which has many disadvantages, such as exchange running away, hacker attacks, etc.; in order to solve this problem, some such as Solutions such as side chains, chain relays, hash locks, etc., but from the actual effect point of view, they cannot solve the problem of cross-chain transactions well.

[0003] Multi-signature technology is to use N public keys to jointly generate a multi-signature address. The signature of M private keys is required to consume the assets on this address. At the same time, N>=M must be satisfied. This is the multi-signature of M / N. By using multi-signature technology, the user's assets can be guaranteed t...
