Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
In the existing blockchain configured with an account model, business logic is realized based on virtual machines and contracts. To ensure security, one contract cannot invoke the assets of another contract. If an A contract can call an asset in a B contract, the A contract is a hypervisor and can destroy the business logic of the B contract: for example, the B-contract is a trade contract, which has a trade that freezes 100MM for a certain user, and gives 100MM to another user if he gives 10NN to him. At this time, if the a contract directly defrosts and retrieves the 100MM in the B contract, it will cause the user who gave the 10NN to be unable to receive the 100 MM.
Therefore, in the prior art, to implement the wallet retrieving function, it is first necessary to transfer several assets to the wallet retrieving contract, that is, only the assets in the wallet retrieving contract can be retrieved.
Fig. 1 is a flowchart of a wallet retrieving method according to an embodiment of the present invention. As shown in fig. 1, in the present embodiment, a wallet retrieving method suitable for a client, a blockchain is configured with an account model, and the method includes:
s12: generating a first wallet retrieval transaction in response to retrieving assets in a second account of the second public key into a first account of the first public key; the signature information of the first wallet retrieving transaction comprises a wallet retrieving identifier, delay information, a first public key and a second public key;
s14: sending the first wallet retrieval transaction to the blockchain network for the blockchain node to:
caching the first wallet retrieval transaction, and determining the initial packaging time according to the delay information;
when the packaging right of the latest first block after the initial packaging time is reached and the packaging right of the latest first block after the initial packaging time is possessed, executing a first wallet retrieval transaction: transferring assets from the second account to the first account; and the number of the first and second groups,
the first block including the first wallet retrieval transaction is broadcast to other blockchain nodes for deletion of local first wallet retrieval transactions by other blockchain nodes.
Specifically, take the example of retrieving an excavation contract asset 1000MM intended to be excavated from addr (a) to addr (b); suppose the delay information is 2021 year, 1 month, 1 day 0:00: 00;
in response to retrieving the excavation contract asset 1000MM intended to excavate from addr (A) to addr (B), the client performs step S12 to generate a wallet retrieval transaction tx1, wherein signature information of tx1 includes { uwallet: public key (A): public key (B): 1/0: 00:00: sigdata1 }; uwallet is a wallet finding identifier, 1 st 0:00:00 in 2021 is delay information, addr (B) is an account of a public key (B), addr (A) is an account of the public key (A), and sigdata1 is signature data obtained after a transaction initiator signs transaction content of tx1 according to a held private key;
the client executes the step S14 to send tx1 to the blockchain network;
the block chain node caches tx1, and determines the initial packing time of tx1, wherein the initial packing time is 2021 year, 1 month, 1 day, 0:00: 00;
assuming that blockchain node A is up to 1 month, 1 day, 0:00:00, 2021 and has packing right of the newest block (100) after 1 month, 1 day, 0:00:00, 2021, node A performs tx 1: transferring the mine excavation contract asset 1000MM from addr (A) to addr (B);
block chain node A will include the block of tx1 (100) to other block chain nodes, which upon receipt of the block (100) delete the local tx 1.
In further embodiments, the delay information may be configured to be a second time length according to actual requirements, and correspondingly, the initial packing time should be determined according to an additionally set time starting point and the second time length, for example, "cache the first wallet retrieval transaction," determine the initial packing time according to the delay information "is configured to" cache the first wallet retrieval transaction, "and determine the initial packing time according to the generation time of the first wallet retrieval transaction and the second time length," which may achieve the same technical effect.
Those skilled in the art will appreciate that 1000MM pertains to a mine excavation contract because tx1 specifies a mine excavation contract executor, and if tx1 does not specify a contract, the global asset 1000MM is divided from addr (A) to addr (B).
It will be understood by those skilled in the art that public key (a) and public key (B) may belong to the same user or may belong to different users.
Those skilled in the art will appreciate that the assets in the "transfer of assets from the second account to the first account" should be active assets, and if the assets are frozen, the assets are thawed and then the thawed assets are transferred from the second account to the first account.
The above embodiments allow any asset to be retrieved.
Preferably, the signature information further includes a third public key of each third account that can manage the second public key, a wallet retrieval determination rule that can successfully execute the first wallet retrieval transaction, and first signature data obtained by signing the transaction content of the first wallet retrieval transaction by a plurality of fourth accounts according to the held private key;
performing the first wallet recovery transaction includes:
judging whether each first signature data in the signature information accords with a wallet retrieval judgment rule:
if so, the first wallet retrieval transaction is executed.
Specifically, the wallet retrieval judgment rule includes at least a first amount of first signature data that should be received and a second amount of first signature data that is correctly signed; judging whether each first signature data in the signature information conforms to the wallet retrieval judgment rule includes "judging whether the number of the first signature data in the signature information is not less than a first number: if yes, judging whether the number of the first signature data with correct signature in the signature information is not less than the second number or not; the public keys of the accounts capable of managing the public key (A) are assumed to be public keys (N1) to (N4); the signature information of tx1 includes { uwallest: addr (A): addr (B):3:2:2021, 1, 0:00:00: sigdata1: sigdata2: sigdata3 }; wherein 3:2 is a recovery judgment rule, 3 indicates that at least 3 signature data need to be obtained, the public keys corresponding to the 3 signature data should be included in the public keys (N1) -public key (N4), and 2 indicates that at least 2 signature data in the 3 signature data are correct; sigdata1: sigdata2: sigdata3 are signature data, and in the current embodiment, it is assumed that sigdata1: sigdata2: sigdata3 are all correct signature data, and the corresponding public keys are all included in public keys (N1) -public key (N4);
because sigdata1, sigdata2, sigdata3 are correct signature data and the corresponding public keys are included in the public keys (N1) -public key (N4), the wallet retrieving judgment rule "3: 2" in tx1 is met, and the node a executes tx 1: divide the mine excavation contract asset 1000MM from addr (A) to addr (B).
In further embodiments, the wallet retrieving determination rule may be further configured according to actual requirements, for example, the configuration is 3: 50%, where 3 indicates that at least 3 signature data need to be obtained, and 50% indicates that at least 2 signature (rounding up of 1.5) data out of the 3 signature data are correct, which can achieve the same technical effect. And those skilled in the art should understand that the multiple signature rules can be configured not only according to the number, but also according to the actual requirement, according to the weight or other parameters, and the same technical effect can be achieved.
Further, the determining whether each first signature data in the signature information complies with the wallet retrieval determination rule includes:
judging whether the fourth accounts belong to the third accounts or not:
if yes, judging whether the number of the first signature data in the signature information is not less than the first number.
In some blockchain systems, the public keys corresponding to the signature data in the wallet retrieval transaction should all belong to the third account, and in other blockchain systems, the public keys corresponding to the signature data in the wallet retrieval transaction may not all belong to the third account as long as the corresponding public keys belong to the number or weight of the third account or other parameters meet the wallet retrieval judgment rule.
It should be understood by those skilled in the art that, when a first wallet retrieval transaction is received, it should be determined first whether the first wallet retrieval transaction is a multiple signature transaction at the same time, that is, the signature information of the wallet retrieval transaction should not lack any of the following parameters, "the third public keys of the third accounts managing the second public key, the wallet retrieval determination rule that can successfully execute the first wallet retrieval transaction, and the first signature data obtained by signing the transaction content of the first wallet retrieval transaction by the fourth accounts according to the held private key"; if any of the above parameters are absent, the wallet retrieval transaction is processed according to actual requirements, e.g., the wallet retrieval transaction is not executed.
Those skilled in the art will appreciate that blockchains support multiple signature types.
In the prior art, the current blockchain only supports some basic signature types such as secp, and in the present application, the blockchain can support more kinds of signature types according to actual requirements. The key space of different signature types is different, for example, the key space of the secp is 0xFFFF FFFF FFFF FFFF FFFF FFFF FFFF FFFE BAAE DCE6 AF48 a03B BFD 25E 8C D0364140, and the key space of the bls is 0x73eda753299D7D483339D80809a1D80553bda402fffe5 bfffffffffffff 00000001, then the block chain node needs to be verified according to the signature type specified by the signature data when verifying the signature data of the wallet recovery transaction.
Further, the wallet retrieving determination rule includes at least a first amount of the first signature data that should be received and a second amount of the first signature data that is correctly signed;
judging whether each first signature data in the signature information conforms to the wallet retrieving judgment rule comprises the following steps:
judging whether the quantity of the first signature data in the signature information is not less than a first quantity:
if yes, judging whether the number of the first signature data with correct signature in the signature information is not less than a second number.
The wallet retrieving principle of the above embodiment can refer to a method of a preferred embodiment shown in fig. 1, and is not described herein again.
Preferably, generating the first wallet retrieval transaction comprises:
generating a first wallet recovery credentialing transaction comprising a first wallet recovery transaction; wherein the first wallet recovery transaction is included in a payload of the first wallet recovery credentialing transaction;
caching the first wallet retrieval transaction, and determining the initial packaging time according to the delay information comprises:
deducting the commission charge of the first wallet for recovering the deposit certificate transaction, and storing the first wallet for recovering the deposit certificate transaction deposit certificate on the blockchain;
and caching the first wallet retrieval transaction, and determining the initial packaging time according to the delay information.
Specifically, tx1 is included in the payload of wallet credentialing transaction tx 2;
deducting the commission charge of tx2 by the blockchain node, and storing tx2 on the blockchain;
the block chain node buffers tx1 in payload of tx2, and determines the starting packing time of tx1 according to the delay information of tx 1.
In the above embodiment, the block link point does not provide a storage service for the multi-signature transaction with the delayed information for free, but needs to charge a certain handling fee, and the above embodiment can prevent the client from sending a large number of multi-signatures with the delayed information and occupying a large amount of local storage space of the block link point, thereby enhancing the security of the block link network.
Further, the delay information is a first time length which is required to be prolonged by the wallet to retrieve the transaction; caching the first wallet retrieval transaction, and determining the initial packaging time according to the delay information comprises:
determining the initial packaging time of the first wallet finding transaction according to the first time and the first time length of the first wallet finding and evidence storing transaction;
storing the first wallet retrieval transaction locally, and storing a first corresponding relation between a first hash value of the first wallet retrieval verification transaction and a second hash value of the first wallet retrieval verification transaction;
wherein the first correspondence is for other blockchain nodes:
when the first wallet retrieving transaction is executed, the first wallet retrieving and evidence storing transaction is found according to the second hash value, and the initial packaging time of the first wallet retrieving and evidence storing transaction is determined according to the first time and the first time length when the first wallet retrieving and evidence storing transaction is packaged;
judging whether the packaging time of the first wallet retrieving transaction is not earlier than the initial packaging time:
otherwise, the first wallet finds that the transaction execution is unsuccessful.
Specifically, assuming that tx2 is packed at the first time of 24/11/2020/0: 00/00, the first time duration is 7 days, and the generation time of the block generated by a is 30/0: 00/12/2020;
determining the starting packing time of tx1 according to the time 2020 of 11, 24, 0:00:00 and 7 days when the block link points are packed according to tx2, wherein the starting packing time of tx1 is 2021, 1, 0:00: 00;
the block chain link point stores tx1 locally and stores the corresponding relation between hash (tx2) and hash (tx 1);
when the other blockchain nodes receive the blocks generated by A and execute to tx1, tx2 is found according to hash (tx1), the initial packaging time of tx1 is determined according to the time 2020 of tx1 being packaged, 11, 24, 0:00:00 and the first time length 7 days, and the initial packaging time of tx1 is 2021, 1, 0:00: 00;
judging whether the node of the other block chains is 0:00:00 not earlier than the initial packaging time 2021, 1 month and 1 day 0:00:00 at 12 months and 30 days in 2020;
since 30/12/2020/0: 00:00 is earlier than 1/2021/0: 00:00 at the start packing time, the other blockchain nodes fail to execute tx 1.
Since most nodes fail to execute tx1, the error block generated by the blockchain node a becomes a block on the side chain, and finally the safety of the asset of addr (a) is guaranteed.
