Fig. 1 is a flowchart of a delayed transaction method according to an embodiment of the present invention. As shown in fig. 1, in this embodiment, the present invention provides a delayed transaction method suitable for a client, where the method includes:
s12: generating a first time delay structure body according to a first public key of a current user and first time delay information needing to be prolonged, and generating a first time delay transfer address according to the first time delay structure body;
s14: generating a delayed transaction; the delayed transaction comprises a first delayed structure body, and the address of a transaction initiator of the delayed transaction is a first delayed transfer address;
s16: generating delayed deposit transaction according to the delayed transaction; wherein, the payload field of the delayed deposit certificate transaction comprises the delayed transaction;
s18: and sending the delayed credit transaction to a block chain network for block chain nodes:
when the delayed certificate-deposit transaction is judged to be the first type of transaction needing delay, deducting the commission charge of the delayed certificate-deposit transaction, determining the initial packaging time of the delayed transaction according to the first delay information, and depositing the delayed certificate-deposit transaction onto the block chain; and the number of the first and second groups,
storing the delayed transactions locally; and the number of the first and second groups,
when the initial packaging time is reached and the packaging right of the latest first block after the initial packaging time is possessed, generating a second delayed transfer address according to a first delayed structure body in delayed transaction, judging whether the second delayed transfer address is the same as the transaction initiator address of the delayed transaction, and judging whether the signature of the delayed transaction is matched with a first public key in the first delayed structure body in the delayed transaction: when the judgment is yes, generating a first block comprising delayed transaction; and the number of the first and second groups,
broadcasting the first block to other blockchain nodes for the other blockchain nodes to:
generating a third delayed transfer address according to a first delayed structure body in delayed transaction, judging whether the third delayed transfer address is the same as a transaction initiator address of the delayed transaction, judging whether a signature of the delayed transaction is matched with a first public key in the first delayed structure body in the delayed transaction, and judging whether the block packing time of a first block is later than the initial packing time: and if the judgment is yes, deleting the local delayed transaction.
Specifically, the first delay information needing to be extended is taken as a first delay time, and the initial packing time of the delayed transaction is determined according to the first delay information, wherein the initial packing time of the delayed transaction comprises 'block packing time of a block of the packed delayed deposit evidence transaction and the first delay time'; and, generating the first block including the deferred transaction comprises generating the first block including the deferred transaction; the first asset appointed by the delayed transaction is transferred to a second user address of a second user from the first delayed transfer address, and the local delayed transaction is deleted, wherein the first asset appointed by the delayed transaction is transferred to the second user account address of the second user from the first delayed transfer address; delete local delayed transactions "as an example;
the client of the user a executes the step S12, generates a delay structure S { pub (a) and T } according to the public key pub (a) of the user a and the first time length T which needs to be extended, and generates a delay transfer address addr (X) according to S; it should be understood by those skilled in the art that the method for generating addr (x) according to S may be configured according to actual requirements, for example, configured to encode S according to protobuf protocol to generate a binary string, and then perform a hash operation on the binary string to generate addr (x), or, for example, configured to encode S according to thrift protocol to generate a binary string, and then perform a hash operation on the binary string to generate addr (x), which is not limited in this application;
the client side of the user a generates a transfer transaction tx0 and sends the transfer transaction tx 0to the blockchain network, and the address of a transaction receiver of tx0 is addr (X); assuming that subsequent user a and user b agree to transfer a delayed transfer after T, and the asset transferred with the delayed transfer is 10 tokens, the asset specified by tx0 should be greater than 10 tokens to ensure that addr (X) has enough assets to be transferred; when the execution of tx0 is successful, the blockchain node transfers the asset specified by tx0 from addr (A) to addr (X); it will be appreciated by those skilled in the art that the above-described transfer transaction may also be generated by other users 'clients, or, a centralized proxy server, as long as user a sends addr (x) to other users' clients, or, a centralized proxy server;
the client of the user a executes the step S14 to generate a delayed transaction tx2, tx2 comprises S, and the transaction initiator address of tx2 is addr (X);
the client of the user a executes the step S16, and generates a delayed credit transaction tx1 according to tx2, where the payload field of tx1 includes tx 2;
the client of the user a executes the step S18 to send tx1 to the blockchain network;
when the block chain node judges that tx1 is the first type of transaction needing delay according to the executor name of tx1, deducting the handling fee of tx1, determining the initial packing time T2 of tx2 according to the block times T1 and T of the blocks packed with tx1, wherein T2 is T1+ T, and storing tx1 into the block chain; those skilled in the art will appreciate that the block link point may also determine whether tx1 is the first type of transaction according to other methods, for example, the determination is made according to the delay identifier in the tx1 signature, which can achieve the same technical effect; and the number of the first and second groups,
the tile link point stores tx2 locally; and the number of the first and second groups,
when T2 is reached and the packing right of the newest block after T2 is possessed (assuming a block with a height of 100), the block link point generates a delayed transfer address addr (X)' according to S in tx 2; it will be understood by those skilled in the art that the method for generating addr (x) 'should be the same as the method for generating addr (x), and for example, should be configured to encode S in tx2 according to protobuf protocol to generate a binary string, and then perform a hash operation on the binary string to generate addr (x)';
the blockchain node judges whether addr (x)' is the same as transaction initiator address addr (x) of tx2, judges whether signature sig _ a of tx2 matches pub (a) in S of tx 2:
since addr (x)' is the same as transaction initiator address addr (x) of tx2, and signature sig _ a of tx2 matches pub (a) in S in tx2, the block link point generates a block (100) comprising tx2, and upon successful execution of tx2, 10token is toggled from addr (x) to addr (b); and the number of the first and second groups,
broadcasting the block (100) to other block chain nodes;
the other block chain nodes generate a delayed transfer address addr (X) according to the S in the tx2, judge whether addr (X) is the same as the transaction initiator address addr (X) in the tx2, judge whether the signature sig _ a of the tx2 is matched with the pub (a) in the S in the tx2, and judge whether the block packaging time of the block (100) is later than T2:
since addr (x) is the same as transaction initiator address addr (x) of tx2, signature sig _ a of tx2 matches pub (a) in S of tx2, block packing time of block (100) is later than T2, and other blockchain nodes divide 10token from addr (x) to addr (b) when tx2 succeeds; and the number of the first and second groups,
remove the local tx 2.
Those skilled in the art will appreciate that tx2 should also perform some verification in the prior art, such as verifying that addr (x) has enough token transfer, and if the verification fails, even if addr (x) is the same as the transaction initiator address of tx2, addr (x) is the same as the transaction initiator address of tx2, signature sig _ a of tx2 matches pub (a) in S of tx2, block packing time of block (100) is later than T2, and tx2 fails to perform;
in more embodiments, the first delay information required to be extended may also be configured according to actual requirements, for example, configured as a fixed time T3, and the starting packing time is T3, so that the same technical effect may be achieved.
In more embodiments, the first asset may not be designated in the delayed transaction, and the first asset may also be configured in the first delay structure according to actual requirements, that is, S { pub (a), T,10token }; each block link point transfers 10 tokens from addr (x) to addr (b) when tx2 succeeds in execution according to 10 tokens in S.
In further embodiments, the signature information of the delayed transaction includes a delayed transaction identifier, and the step "generate the second delayed transfer address … … according to the first delayed structure in the delayed transaction" is performed only when the block link node recognizes the delayed transaction identifier, and the step "generate the third delayed transfer address … … according to the first delayed structure in the delayed transaction" is performed only when the other block link nodes recognize the delayed transaction identifier.
It should be understood by those skilled in the art that the first delay information may also be replaced by a delay block height parameter according to the actual requirement, and the delay block height parameter may also be configured according to the actual requirement, for example, configured as a certain fixed end block height, or configured as a first block interval, and then the end block height is equal to the sum of the block height of the block of the packed tx1 and the first block interval, so that the same technical effect can be achieved.
It will be understood by those skilled in the art that addr (X) is not a contract address for any contract, and thus any contract may call an asset in addr (X). The above-described embodiments make asset invocation more flexible.
