s17: and sending the first delayed credit transaction to a blockchain network for blockchain nodes:
when the first delayed certificate-depositing transaction is judged to be a first-class transaction needing delay, deducting the commission charge of the first delayed certificate-depositing transaction, determining the initial packaging time of the first delayed transaction according to the first delay information, and depositing the first delayed certificate-depositing transaction on the block chain; and the number of the first and second groups,
storing the first delayed transaction 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 the first delayed transaction, judging whether the second delayed transfer address is the same as the address of a first transaction initiator, and judging whether the signature of the first delayed transaction is matched with the first proxy address in the first delayed structure body in the first delayed transaction: when the judgment is yes, generating a first block comprising a first 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 the first delayed transaction, judging whether the third delayed transfer address is the same as the address of a first transaction initiator, judging whether the signature of the first delayed transaction is matched with the first proxy address in the first delayed structure body in the first delayed transaction, and judging whether the block packing time of the first block is later than the initial packing time: and when the judgment is yes, deleting the local first delayed transaction.
Specifically, to generate a first block that includes a first delayed transaction includes "generating a first block that includes a first delayed transaction; transferring the first asset specified by the first delayed transaction from the first delayed transfer address to the second user account address, and deleting the local first delayed transaction comprises transferring the first asset specified by the first delayed transaction from the first delayed transfer address to the second user account address; delete local first deferred transaction "; the first delay information is first delay time, and the initial packaging time of the first delay transaction is determined according to the first delay information, wherein the initial packaging time of the first delay transaction comprises 'the first block time of the first delay deposit evidence transaction is packaged, and the initial packaging time of the first delay transaction is determined according to the first delay time';
after a user a registers proxy delay service to a proxy server, the user a delays transfer to a user b;
a client of a user a generates registration request information for requesting proxy delay service and sends the registration request information to a proxy server;
the proxy server executes step S11 to assign a proxy address, which is assumed to be addr (p), to user a;
a client of a user a generates delayed transaction address generation request information and sends the delayed transaction address generation request information to a proxy server, wherein the delayed transaction address generation request information comprises a delayed time length T;
the proxy server executes step S12, and receives the delayed transaction address generation request message;
the proxy server executes step S13, generates a delay structure S { T, addr (P) } according to T, addr (P), and generates a delay transaction 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;
when the proxy server executes the step S13, the proxy server may also return addr (x) to the user a, so that the client of the user a generates the transfer transaction tx0 and sends the transfer transaction tx 0to the blockchain network, where the transaction receiver address 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);
or the client of the user a can also delegate the proxy server to generate the transfer transaction tx0, because the proxy server itself holds addr (x), the proxy server can generate tx0 and send to the blockchain network after receiving the transfer transaction generation request information generated by the client of the user a;
responding to the confirmation of the user a to delay the transfer to the user b, the client of the user a generates delayed transaction generation request information and sends the delayed transaction generation request information to the proxy server, wherein the delayed transaction generation request information comprises addr (b);
the proxy server executes step S14, and receives the delayed transaction generation request message;
the proxy server executes the step S15 to generate a delayed transaction tx 2; the address of a transaction initiator of tx2 is addr (X), the address of a transaction receiver of tx2 is addr (b), and tx2 comprises S;
the proxy server executes the step S16, and generates a delayed credit transaction tx1 according to tx 2; the payload field of tx1 includes tx 2;
the proxy server executes the step S17 to send tx1 to the blockchain network;
the block link point judges that tx1 is the first type of transaction needing time delay according to the actuator name of tx1, deducts the commission charge of tx1, determines the initial packing time T2 of tx2 according to the block times T1 and T of tx1 (T2 is T1+ T), and stores 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;
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 appreciated by those skilled in the art that the method of generating the transfer address addr (x) 'herein should be the same as the method of generating the transfer address addr (x), and for example, should be correspondingly configured to encode S in tx2 according to the prot obuf protocol to generate a binary string, which is then hashed 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 _ proxy of tx2 matches addr (p) in S of tx 2:
since addr (x)' is the same as addr (x) of the transaction initiator address of tx2, and since addr (p) is an address of the proxy server, signature sig _ proxy of tx2 matches addr (p) in S in tx2, the block link point generates a block (100) comprising tx2, and when tx2 is successfully executed, 10token is shifted 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 tx2, judge whether addr (X) is the same as the transaction initiator address addr (X) in tx2, judge whether the signature sig _ proxy of tx2 is matched with the addr (p) in the S in tx2, and judge whether the block time of the packed tx1 is later than T2:
since addr (x)' is the same as addr (x) of the transaction initiator address of tx2, and signature sig _ proxy of tx2 matches addr (p) in S of tx2, the block time of packed tx1 is later than T2, and other blockchain nodes will divide 10token from addr (x) to addr (b) when tx2 succeeds in execution; 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 sufficient 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 _ proxy of tx2 matches addr (p) in S of tx2, block time of packed tx1 is later than T2, and tx2 still 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 "generating the second delayed transfer address … … according to the first delayed structure in the first delayed transaction" is performed only when the block link node recognizes the delayed transaction identifier, and the step "generating the third delayed transfer address … … according to the first delayed structure in the first 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 should be understood by those skilled in the art that if the second user registers the proxy delayed service on the proxy server, the proxy server may push the transaction hash of the first delayed deposit transaction to the second client of the second user when the first delayed deposit transaction is verified on the monitored blockchain, or push the transaction hash of the first delayed transaction to the second client when it is monitored that the blockchain node executes the first delayed transaction.
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.
Preferably, determining the initial packaging time of the first delayed transaction according to the first delay information, and depositing the first delayed deposit transaction onto the block chain includes:
determining the initial packaging time of the first delay transaction according to the first delay information;

Specifically, the block link point determines the starting packing time T2 of tx2 according to the block times T1 and T of the blocks of the packed tx1, wherein T2 is T1+ T;

the block chain node judges whether addr (X) is the same as transaction initiator address addr (X) of tx2, judges whether signature sig _ proxy of tx2 is matched with addr (p) in S of tx2, searches whether tx1 exists on the chain according to the corresponding relation, and judges whether the searched tx1 is a first-type transaction;
since addr (x)' is the same as transaction initiator address of tx2, signature sig _ proxy of tx2 is matched with addr (p) in S of tx2, tx1 can be found on the block chain, the found tx1 is the first type of transaction, and the block chain node generates the first block including tx 2; those skilled in the art should understand that, in further embodiments, addr (x)' may be configured differently from addr (x), and/or tx1 may not be found on the block chain, and/or tx1 found is not an operation of the first type transaction, for example, configured to unpack tx 2;
