assuming that after a user a registers a proxy delay service with a proxy server, the user a delays transfer to a user b;
the client of the user a generates registration request information for requesting the proxy delay service and sends the registration request information to the proxy server;
the proxy server executes step S11 to assign a proxy address, assumed as addr (p), to user a;
the client of the user a generates delay transaction address generation request information and sends the delay transaction address generation request information to the proxy server, wherein the delay transaction address generation request information comprises delay time length T;
The proxy server executes step S12 to receive delay transaction address generation request information;
the proxy server executes step S13 to generate 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 hash the binary string to generate addr (X), or configured to encode S according to thraft protocol to generate a binary string, and hash the binary string to generate addr (X), which is not specifically limited in this application;
when executing 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 address of the transaction receiver of tx0 is addr (X); assuming that the subsequent user a and user b are about to transfer after T with a delayed transfer of 10token for the asset specified by tx0, the asset should be greater than 10token to ensure that addr (X) has enough assets to be transferred; when the execution of tx0 is successful, the blockchain node skips the asset specified by tx0 from addr (a) to addr (X);
Alternatively, the client of the user a may proxy the proxy server to generate the transfer transaction tx0, because the proxy server itself holds addr (X), and the proxy server may proxy and send the transfer transaction tx0 to the blockchain network after receiving the transfer transaction generation request information generated by the client of the user a;
the client of the user a responds to the confirmation of the user a to delay transfer to the user b, generates delay transaction generation request information and sends the delay transaction generation request information to the proxy server, wherein the delay transaction generation request information comprises addr (b);
the proxy server executes step S14 to receive delay transaction generation request information;
the proxy server executes step S15 to generate a delay transaction tx2; tx2 has a transaction initiator address addr (X), tx2 has a transaction receiver address addr (b), and tx2 includes S;
the proxy server executes step S16 to generate a delayed certificate-storing transaction tx1 according to tx2; the payload field of tx1 includes tx2;
the proxy server executes step S17 to send tx1 to the blockchain network;
the blockchain node judges that tx1 is a first type transaction needing delay according to the name of an executor of tx1, deducts the commission of tx1, determines an initial packaging time T2 (T2=T1+T) of tx2 according to the block time T1 and T of packaging tx1, and stores tx1 on a blockchain; it should be understood by those skilled in the art that the blockchain node may also determine whether tx1 is a first type of transaction according to other methods, for example, determining according to a delay identifier in the tx1 signature, so as to achieve the same technical effect;
The block link point stores tx2 locally; the method comprises the steps of,
when reaching T2 and having the packing weight of the latest block after T2 (the block with the height of 100 is assumed), the blockchain node generates a delay transfer address addr (X)' according to S in tx 2; it should be understood by those skilled in the art that the method for generating the transfer address addr (X) 'herein should be the same as the method for generating the transfer address addr (X), for example, should be correspondingly configured to encode S in tx2 according to the prot obuf protocol to generate a binary string, and hash the binary string to generate addr (X)';
the blockchain node determines whether addr (X)' is the same as the transaction initiator address addr (X) of tx2, and determines whether the signature sig_proxy of tx2 matches addr (p) in S in tx 2:
since addr (X)' is the same as the transaction initiator address addr (X) of tx2, and since addr (p) is one address of the proxy server, the signature sig_proxy of tx2 matches with the ad dr (p) in S in tx2, then the block link point generates a block (100) including tx2, and when executing tx2 succeeds, the 10token is scratched from addr (X) to addr (b); the method comprises the steps of,
broadcasting blocks (100) to other blockchain nodes;
the other blockchain nodes generate a delayed transfer address addr (X) according to S in tx2, judge whether the addr (X) is identical with a transaction initiator address addr (X) of tx2, judge whether signature sig_proxy of tx2 is matched with addr (p) in S in tx2, and judge whether the block time of packing tx1 is later than T2:
Since addr (X) "is the same as the address addr (X) of the transaction initiator of tx2, and the signature sig_proxy of tx2 is matched with addr (p) in S in tx2, the block time of packing tx1 is later than T2, and then other block chain nodes scratch 10token from addr (X) to addr (b) when tx2 is successfully executed; the method comprises the steps of,
the local tx2 is deleted.
It will be appreciated by those skilled in the art that if tx2 performs successfully some verification in the prior art, such as verifying that addr (X) has enough token transfers, if verification fails, then if addr (X)' is the same as the transaction initiator address of tx2, addr (X) "matches the addr (p) in S in tx2, the signature sig_proxy of tx2 matches addr (p) in S in tx2, and the block of packed tx1 is later than T2, and tx2 fails to perform;
in more embodiments, the first delay information to be prolonged may be further configured according to actual requirements, for example, configured as a fixed time T3, and the starting packaging time is T3, so that the same technical effects can be achieved.
In further embodiments, the first asset may not be specified in the delay transaction, and the first asset may also be configured in the first delay fabric according to actual needs, i.e., S { pub (a), T,10token }; each block link point then strokes 10token from addr (X) to addr (b) upon successful execution of tx2 according to 10token in S.
In further embodiments, the signature information of the delayed transaction includes a delayed transaction identifier, and the blockchain node performs the step of generating the second delayed transfer address … … according to the first delayed structure in the first delayed transaction when the delayed transaction identifier is identified, and the other blockchain nodes perform the step of generating the third delayed transfer address … … according to the first delayed structure in the first delayed transaction when the delayed transaction identifier is identified.
It should be understood by those skilled in the art that the first delay information may be replaced by a delay block height parameter according to the actual requirement, and the delay block height parameter may be configured according to the actual requirement, for example, configured as a certain fixed end block height, or configured as a first block section, where the end block height is equal to the sum of the block height of the blocks packaged tx1 and the first block section, so as to achieve the same technical effect.
It will be appreciated by those skilled in the art that if the second user also registers a proxy delay service on the proxy server, the proxy server may push the transaction hash of the first delayed forensic transaction to the second client of the second user when the first delayed forensic transaction is forensic on the monitoring block chain, or send the transaction Ha Xitui of the first delayed transaction to the second client when the blockchain node is monitored to have performed the first delayed transaction.
Those skilled in the art will appreciate that addr (X) is not the contract address of any contract, so any contract may call an asset in addr (X). The above-described embodiments make asset invocation more flexible.
