when the verification is correct, the first multiple signature transaction is executed.
Specifically, generating the first multi-signature address according to the first multi-signature structure includes "encoding the first multi-signature structure according to a protobuf protocol to generate a first binary string; performing a hash operation on the first binary string to generate a first multiple signature address, verifying whether the second multiple signature address matches the second multiple signature structure comprises "encoding the second multiple signature structure according to a protobuf protocol to generate a second binary string; performing a hash operation on the second binary string to generate a third multi-signature address; judging whether the third multiple signature address is the same as the second multiple signature address; and generating a second multiple signature transaction according to the first signature data, the plurality of second signature data, the second multiple signature structure and the second multiple signature address comprises generating the second multiple signature transaction according to a multiple signature transaction identifier, the first signature data, the plurality of second signature data, the second multiple signature structure and the second multiple signature address, and judging that the second multiple signature transaction is a multiple signature transaction according to the multiple signature transaction identifier of the second multiple signature transaction when the second multiple signature transaction is judged to be the multiple signature transaction; verifying whether the first signature data and each second signature data meet the second multiple signature structure comprises verifying whether the first public key and each fifth public key belong to the public keys included in the second multiple signature structure; verifying whether the weights of the current account and the account corresponding to each second signature data meet the second operation weight or not is taken as an example;
suppose user a, user B, user C, user D, user E determine multiple signature rules: if any one of the users A to E wants to transfer money from the generated multiple signature addresses, the transfer needs to be agreed by at least any two of the users A to E;
taking the current client as the client of the user A as an example;
the client of the user A executes the step S12, responds to the client of the user B to the client of the user E to determine the multiple signature rules, and generates a multiple signature structure S according to the multiple signature rules, wherein the multiple signature structure S comprises pub (a) -pub (E) and has the operation weight of 5: 2; coding S according to a protobuf protocol to generate a first binary string; performing a hash operation on the first binary string to generate a multiple signature address addr (M);
the client side of the user E responds to the request of the user E, takes 100coin from addr (M), generates transaction content (addr (M), addr (E),100coin) and signature request information comprising the transaction content, and sends the signature request information to the client sides of the users A to D;
the client of the user a executes the step S14, receives the signature request information, and considers that the transaction content is correct, then the client of the user a signs the transaction content according to pri (a) to generate signature data sigdata (a), and sends sigdata (a) to the client of the user E; similarly, the client of the user B generates signature data sigdata (B) and sends the sigdata (B) to the client of the user E;
the client of user E generates a multiple signature transaction tx1(addr (m)), multiple signature transaction identifications multisig, S, sigdata (a), sigdata (b)); those skilled in the art will appreciate that a multiple signature transaction is generated by the client of E, and the transaction recipient defaults to E; in further embodiments, the transaction recipient may also be specified in tx1, i.e., tx1 further includes the transaction recipient address addr (e), which may achieve the same technical effect;
the client of user E sends tx1 to the blockchain network;
the blockchain node judges that tx1 is a multi-signature type transaction through multi-signature transaction identification multisig, the blockchain node encodes S in tx1 according to a protobuf protocol to generate a second binary character string, performs hash operation on the second binary character string to generate a multi-signature address addr (M), and judges whether addr (M) is the same as addr (M);
verifying whether the public key corresponding to sigdata (A) and sigdata (B) belongs to the public key included in S by the blockchain node;
the block chain node verifies whether sigdata (A) and sigdata (B) meet 5: 2;
since addr (m)' is the same as addr (m), public keys pub (a) and pub (B) corresponding to sigdata (a) and sigdata (B) belong to the public keys pub (a) to pub (e)) included in S, sigdata (a) and sigdata (B) satisfy 5:2, and the block link point executes tx 1.
In further embodiments, the manner of generating the first multi-signature address according to the first multi-signature structure may also be configured according to actual requirements, for example, configured to encode the multi-signature structure according to a protocol (e.g., thrift) other than protobuf to generate a binary string, and then perform a hash operation according to the generated binary string to generate the multi-signature address, and accordingly, verify whether the second multi-signature address matches the second multi-signature structure should be configured to "encode the second multi-signature structure according to thrift protocol to generate the second binary string; performing a hash operation on the second binary string to generate a third multi-signature address; and judging whether the third multiple signature address is the same as the second multiple signature address or not, thereby realizing the same technical effect.
In more embodiments, the multiple signature addresses may not include the re-signature transaction identifier, and the determination method of the multiple signature transactions may also be configured according to actual requirements, for example, configured to determine that the multiple signature transactions are multiple signature transactions according to the first byte of the multiple signature transactions, so that the same technical effect may be achieved.
In more embodiments, the manner of verifying whether the first signature data and each second signature data satisfy the second multiple signature structure may also be configured according to actual requirements, for example, the manner of verifying whether the first signature data and each second signature data satisfy the second multiple signature structure includes verifying whether a public key corresponding to a first address of the first current account and a fifth address corresponding to each fifth account belongs to a public key included in the second multiple signature structure; and verifying whether the weights of the current account and the account corresponding to each second signature data meet the second operation weight, so that the same technical effect can be realized.
In further embodiments, different operation weights may be configured for different users according to actual requirements, for example, if the operation weights of the users a to C are configured to be 1.2, and the operation weights of the users D to E are configured to be 0.7, if tx1 only includes sigdata (D) and sigdata (E), the sum of the weights of tx1 is 5:1.4, and does not satisfy 5:2, and the tx1 executed by the block link point fails.
