Example one
The application provides a multi-signature transaction implementation method, as shown in fig. 1, including:
the multi-signature transaction requested by the multi-signature transaction request is related to the multi-signature account, the multi-signature account corresponds to a multi-signature address, and the multi-signature address is constructed based on public keys of more than two nodes in the same block chain;
in the embodiment of the present application, a multi-signature transaction request created by any node (may be one of the two or more nodes, may also be a node in the same block chain with the two or more nodes, and may also be a node not in the same block chain with the two or more nodes) is received.
102, simultaneously triggering more than two nodes to respectively sign the multi-signature transaction and feeding back transaction information with the signature based on the multi-signature transaction request;
in this embodiment, in response to the multi-signature transaction request, the two or more nodes may be triggered at the same time, so that the two or more nodes compete for signing the multi-signature transaction and feed back the transaction information with the signature.
In an application scenario, a competitive multi-signature contract may be created based on the multi-signature transaction request, that is, the multi-signature transaction is written into the competitive multi-signature contract, then the competitive multi-signature contract triggers the two or more nodes to check the multi-signature transaction at the same time, and when the node checks the competitive multi-signature contract, the node may perform an action of signing the multi-signature transaction and feeding back transaction information with a signature.
103, when the transaction information fed back by the target number of nodes is received, merging the signatures carried in the received transaction information into the multi-signature transaction to obtain a merged signature transaction; the merged signature transaction includes all signatures in the received transaction information, so that any node (whether the node corresponding to the multi-signature address or the nodes of other block chains) can verify the validity of the transaction information through the signatures in the merged signature transaction.
In this embodiment of the present application, after receiving the transaction information fed back by the target number of nodes, the signatures in the received transaction information may be merged, and the merged signatures are written into the multi-signature transaction, so as to enable the multi-signature transaction to take effect, where the target number is not less than the number of signatures required when the multi-signature address is called.
Optionally, the multi-signature transaction implementation method further includes:
when the transaction information is received and the number of the received transaction information does not exceed the target number, extracting the signature in the currently received transaction information and storing the signature in a preset storage space;
the merging of the signature carried in the received transaction information into the multi-signature transaction specifically includes: and extracting and combining the signatures which are stored in the storage space and are related to the multi-signature transaction into the multi-signature transaction.
Specifically, the preset storage space may be a state of the competitive multiple signature contract; when the transaction information is received and the number of the received transaction information does not exceed the target number, the signature is extracted and stored once, and the interval time for each node to sign the multi-signature transaction can be utilized to the maximum extent, so that the execution efficiency of the multi-signature transaction is improved.
Optionally, after receiving the multi-signature transaction request, the multi-signature transaction implementation method further includes:
based on the multi-signature transaction request, judging whether the importance of the multi-signature transaction is higher than a preset value, wherein the multi-signature transaction request comprises: the importance of the multi-signature transaction;
and if the importance of the multi-signature transaction is higher than the preset value, updating the number of the multi-signature addresses needing to be signed based on the importance of the multi-signature transaction, acquiring the public keys of the more than two nodes, updating the multi-signature addresses based on the public keys of the more than two nodes and the number of the multi-signature addresses needing to be signed, updating the multi-signature transaction based on the current multi-signature addresses, and determining the number of the multi-signature addresses needing to be signed as a target number.
Specifically, the updating the multi-signature transaction based on the current multi-signature address may specifically be:
generating a new transaction based on the current multi-signature address and the multi-signature transaction request;
updating the multi-signed transaction to the new transaction.
It should be noted that the number of signatures required is the number of signatures required when a multi-signature address is called; based on the steps, when the multi-signature transaction is more important (for example, when the fund amount related to the multi-signature transaction is greater than the preset fund amount, the importance degree of the multi-signature transaction can be set to be a value greater than the preset value in the multi-signature transaction request), a multi-signature address with the signature quantity larger than the original quantity is regenerated, and the new signature quantity is determined to be the target quantity, so that the technical effect that the multi-signature transaction can be continued under the condition that more people perform signature confirmation is achieved, and the reliability of the multi-signature transaction is improved.
Further, after the determining whether the importance of the multi-signature transaction is higher than a preset value, the method for implementing the multi-signature transaction further includes:
and if the importance of the multi-signature transaction is not higher than the preset value, determining the current number of the multi-signature addresses needing to be signed as a target number.
As can be seen from the above, the technical solution of the present application receives a multi-signature transaction request; triggering more than two nodes simultaneously to sign the multi-signature transaction and feeding back the transaction information with the signature based on the multi-signature transaction request; when transaction information fed back by a target number of nodes is received, the signatures carried by the received transaction information are merged into multi-signature transactions to obtain merged signature transactions. Based on the technical scheme of the application, all nodes which simultaneously trigger and construct multi-signature addresses can respectively sign the multi-signature transaction and feed back the transaction information with the signature, and after the target number of transaction information is received, all the received signatures are combined into the multi-signature transaction, so that the situation that different nodes need to carry out signature in turn is avoided, and the execution efficiency of the multi-signature transaction is improved.
The following describes a multi-signature implementation in the embodiment of the present application in an application scenario. In the application scenario, the service related parties related to the multi-signature transaction comprise a node a, a node B, a node C and a node D, wherein the node a, the node B and the node C are one party of the multi-signature transaction, common assets of the node a, the node B and the node C are managed by a common account corresponding to a multi-signature address (the multi-signature transaction requires signatures of any two nodes of the node a, the node B and the node C to use the common account to call the common assets), the node D is the other party of the multi-signature transaction, and two parties of the multi-signature transaction are in two different block chains;
under the above premise, the complete flow of multi-signature transaction may be as follows:
the method comprises the following steps that firstly, any party in the multi-signature transaction creates a multi-signature transaction request, wherein the multi-signature transaction requested by the multi-signature transaction request needs to call the common asset;
secondly, establishing a competitive multi-signature contract based on the multi-signature transaction request, and writing the multi-signature transaction into the competitive multi-signature contract;
thirdly, writing the multi-signature transaction into a signature waiting storage space of the competitive multi-signature contract by using the multi-signature address as an identifier;
fourthly, the node A, the node B and the node C can find that one multi-signature transaction related to the node A needs to be completed in the storage space waiting for signature of the competitive multi-signature contract;
fifthly, after confirming that the multi-signature transaction is normal, the node a, the node B and the node C may extract the multi-signature transaction from the storage space waiting for signature of the competitive multi-signature contract to perform signature to generate a transaction containing signature (i.e. the transaction information with signature mentioned in the foregoing method embodiment), and then submit the transaction containing signature through the competitive multi-signature contract;
it should be noted that, due to the characteristic that the intelligent contract (the competitive multiple signature contract) is executed serially in the block chain, the actions of the node a, the node B and the node C submitting the transaction containing the signature must have an execution sequence in advance, and it is assumed that the execution sequence is that the node B submits the transaction containing the signature first, the node a submits the transaction containing the signature second and the node C submits the transaction containing the signature last;
sixthly, when the competitive multi-signature contract receives a transaction containing a signature submitted by a node B, detecting whether the multi-signature transaction is not signed; after detecting that the signature is not finished, verifying whether the signature in the transaction containing the signature submitted by the node B is correct or not; after the signature is detected to be correct, extracting the signature in the transaction containing the signature submitted by the node B and storing the signature in a signature storage space of the multi-signature transaction, wherein the signature storage space is a storage space for storing the signature in the multi-signature transaction;
seventhly, when the competitive multi-signature contract receives a transaction containing a signature submitted by the node A, detecting whether the multi-signature transaction is not signed; after the incomplete signature is detected, verifying whether the signature in the transaction containing the signature submitted by the node A is correct or not; after the signature is detected to be correct, extracting the signature in the transaction containing the signature submitted by the node A and storing the signature in a signature storage space of the multi-signature transaction;
eighthly, when the competitive multi-signature contract receives a signature-containing transaction submitted by a node C, detecting whether the multi-signature transaction is not signed; after the signature is detected to be completed (at the moment, the competitive multi-signature contract receives the signatures of the two nodes and can call the common account), discarding the transaction containing the signature submitted by the node C;
it should be noted that, after the multi-signature transaction completes the signature, the multi-signature transaction may be extracted from the competitive multi-signature contract, and the multi-signature transaction is broadcasted on the block chain where the node D is located to complete the multi-signature transaction with the node D.
