when the first wallet recovery certificate transaction is judged to be a first type transaction requiring delay recovery of the asset, deducting the commission of the first wallet recovery certificate transaction, determining the initial packaging time of the first wallet recovery transaction according to the block packaging time of a second block for packaging the first wallet recovery certificate transaction and the first delay time, and storing the first wallet recovery certificate transaction and the second hash value of the first wallet recovery transaction on a block chain; the method comprises the steps of,
storing the first wallet retrieve transaction locally; the method comprises the steps of,
when the initial packaging time is reached and the latest packaging right of the first block after the initial packaging time is possessed, generating a second wallet retrieving address according to a first wallet retrieving structure in the first wallet retrieving transaction, judging whether the second wallet retrieving address is the same as the address of a first transaction initiator, and judging whether the signature of the first wallet retrieving transaction is matched with the first standby account address in the first wallet retrieving structure in the first wallet retrieving transaction: if the judgment is yes, generating a first block comprising a first wallet retrieving transaction; the method comprises the steps of,
broadcasting the first block to other blockchain nodes for the other blockchain nodes:
generating a third wallet retrieving address according to a first wallet retrieving structure in the first wallet retrieving transaction, judging whether the third wallet retrieving address is identical to the address of a first transaction initiator, judging whether a signature of the first wallet retrieving transaction is matched with the address of a first standby account in the first wallet retrieving structure in the first wallet retrieving transaction, and judging whether the block packing time of a first block is later than the initial packing time: and deleting the local first wallet to retrieve the transaction when the judgment is yes.
Specifically, generating a first chunk including the first wallet retrieve transaction includes "generating a first chunk including the first wallet retrieve transaction; transferring the first asset specified by the first wallet retrieve transaction from the first wallet retrieve address to the first alternate account address, deleting the local first wallet retrieve transaction including "transferring the first asset specified by the first wallet retrieve transaction from the first wallet retrieve address to the first alternate account address; deleting the local first wallet retrieve transaction as an example;
assuming that the main account address of the user a is addr (a), the standby account address is addr (a)', and the delay time is T;
the client side of the user a with the addr (a) generates a wallet retrieving structure S { addr (a), addr (a) ', T } according to the addr (a), addr (a)', T, and generates a wallet retrieving address addr (X) according to the 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;
a client of the user a holding addr (a) generates a transfer transaction tx0 and sends the transfer transaction tx0 to the blockchain network, and a transaction receiver address of tx0 is addr (X); when the execution of tx0 is successful, the blockchain node skips the asset specified by tx0 from addr (a) to addr (X); it will be appreciated by those skilled in the art that the transfer transaction described above may also be generated by the clients of other users, or by a centralized proxy server, provided that user a sends addr (X) to the clients of other users, or by a centralized proxy server;
in response to the user a losing the private key corresponding to the addr (a), the client side of the user a holding the addr (a) ' executes step S12, generates a wallet retrieving structure S { a ddr (a), addr (a) ', T } according to the addr (a), addr (a) ', and generates a wallet retrieving address addr (X) according to S;
the client of the user a holding addr (a)' executes step S14 to generate a wallet retrieving transaction tx2; tx2 includes S, tx2 having a transaction initiator address addr (X), and tx2 having a transaction receiver address addr (a)';
the client of the addr (a)' held by the user a executes step S16, and a wallet retrieving certificate transaction tx1 is generated according to tx2; the payload field of tx1 includes tx2;
the client of the user a holding addr (a)' executes step S18 to send tx1 to the blockchain network;
when judging that tx1 is a first type transaction needing to be delayed according to the name of an executor of tx1, deducting the handling fee of tx1, determining an initial packaging time T2 of tx2 according to the block time T1 and the block time T of a block packaging tx1, wherein T2=T1+T, and storing tx1 and hash (tx 2) 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 right of the latest block after T2 (the block with the height of 100 is assumed), the blockchain node generates a wallet retrieving transfer address a ddr (X)' according to S in tx2; it will be appreciated by those skilled in the art that the method of generating addr (X) 'herein should be the same as the method of generating addr (X), for example, should be correspondingly configured to encode S in tx2 according to the protobuf protocol to generate a binary string, and then 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 of tx2 matches addr (a)' in S in tx 2:
since addr (X) ' is the same as the transaction initiator address addr (X) of tx2 and the signature of tx2 matches addr (a) ' in S in tx2 (the client-generated transaction holding addr (a) ' must go through the private key signature of the client holding addr (a) ' and thus match), then the block link point generates a block (100) including tx2 and, when executing tx2 is successful, the asset in addr (X) is scratched to addr (a) '; the method comprises the steps of,
broadcasting blocks (100) to other blockchain nodes;
other blockchain nodes generate wallet retrieving transfer addresses addr (X) ", judge whether addr (X)", which are the same as transaction initiator addresses addr (X) of tx2, judge whether signatures of tx2 are matched with addr (a)' in S of tx2, and judge whether block packing time of block (100) is later than T2:
since addr (X) ' is the same as addr (X) of the transaction initiator address of tx2, the signature of tx2 matches addr (a) ' in S in tx2, and the block packing time of block (100) is later than T2, then when tx2 execution succeeds, the asset in addr (X) is scratched to addr (a) '; 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 transaction initiator address of tx2, the signature of tx2 matches addr (a) ' in S in tx2, the block packing time of b lock (100) is later than T2, and tx2 fails to perform;
in more embodiments, the first delay time may be replaced by a fixed time T3 according to actual requirements, and the starting packaging time is T3, so that the same technical effects can be achieved.
In more embodiments, the signature information of the wallet retrieving includes a wallet retrieving transaction identifier, and the blockchain node performs the step of generating the second wallet retrieving address … … according to the first wallet retrieving structure in the first wallet retrieving transaction when the wallet retrieving transaction identifier is identified, and the other blockchain nodes perform the step of generating the third wallet retrieving address … … according to the first wallet retrieving structure in the first wallet retrieving transaction when the wallet retrieving transaction identifier is identified.
It should be understood by those skilled in the art that the first delay time length 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 that the same technical effect may be achieved.
It should be understood by those skilled in the art that addr (X) is not any contract address, if user a does not lose the private key corresponding to addr (a), the client side of user a holding addr (a) may invoke the asset in addr (X) with any contract, but after the transaction (including S, where the address of the sender of the transaction is addr (X)) of the asset in addr (X) generated by the client side of user a holding addr (a) is sent to the blockchain network, the blockchain node still generates a wallet retrieving address according to S in the transaction, determines whether the generated wallet retrieving address is the same as the address of the initiator of the transaction, and determines whether the signature of the transaction matches with the first main account address in S in the transaction; only if the above-mentioned decisions are yes, the transaction can be successfully executed.
In the prior art, whether the wallet can retrieve depends on wallet retrieving rules on the chain, and the rules need to occupy storage resources on the chain; in the application, any wallet retrieving rule is not recorded on the chain, only tx1 and hash (tx 2) are stored, and the wallet retrieving function can be realized without occupying storage resources on the chain.
