In further embodiments, the delay information of the delayed transaction may also be configured in other fields according to actual requirements. It will be understood by those skilled in the art that when the delay information for the delayed transaction is configured in the signature information, the assets delayed in the delayed transaction may be not only assets in the delayed contract, but also assets of other contracts (i.e., the actuator name for the delayed transaction is configured as other contracts outside the delayed contract), or global assets (i.e., the actuator name for the delayed transaction is configured as null).
In more embodiments, the manner of determining whether the delayed credit-saving transaction is the first type of transaction that needs to be delayed may also be configured according to actual requirements, for example, the manner is configured that a hash value of a delayed transaction executor is recorded on a block chain, hash operation is performed according to an executor name of the delayed credit-saving transaction to obtain a hash value ', and whether the hash value is the same as the hash value' is determined to determine whether the delayed credit-saving transaction is the first type of transaction that needs to be delayed, so that the same technical effect can be achieved.
The above-described embodiments enhance blockchain network security.
Preferably, when the delayed deposit receipt is determined to be the first type of receipt needing delaying, deducting the commission charge of the delayed deposit receipt includes:
and judging that the delayed evidence-depositing transaction is the first type of transaction needing delay according to the executor name of the delayed evidence-depositing transaction, and deducting the commission charge of the delayed evidence-depositing transaction.
The delayed transaction generation principle of the above embodiment may refer to the method shown in fig. 1, and is not described herein again.
In the scenario shown in FIG. 1, tx1 is packed into blocks in advance if blockchain node A is bad, and other nodes cannot verify that tx1 is packed after a sufficient amount of time. The above mechanism would render the asset of the transaction sender of tx1 insecure.
The above problem can be solved by the following embodiments:
preferably, the delay information is a first time length required to be prolonged by the delayed transaction; storing the delayed transaction to the local, and determining the initial packaging time of the delayed transaction according to the delayed information comprises the following steps:
determining the initial packaging time of the delayed transaction according to the first time and the first time length of the packaged delayed deposit evidence transaction;
storing the delayed transaction locally, and storing a first corresponding relation between a first hash value of the delayed evidence transaction and a second hash value of the delayed transaction;
wherein the first correspondence is for other blockchain nodes:
when the delayed transaction is executed, the delayed evidence storing transaction is found according to the second hash value, and the initial packaging time of the delayed transaction is determined according to the first time and the first time length at which the delayed evidence storing transaction is packaged;
judging whether the packaging time of the delayed transaction is not earlier than the initial packaging time:
otherwise, the delayed 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 7days, 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 7days 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 7days, 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 the transaction sender of tx1 is guaranteed.
Preferably, the first signature information of the delayed transaction includes delayed information of the delayed transaction.
The delayed transaction generation principle of the above embodiment may refer to the method shown in fig. 1, and is not described herein again.
Further, the generating the first block according to the delayed transaction includes:
judging whether each first signature data in the first signature information accords with a multiple signature judgment rule:
if yes, generating a first block according to the delayed transaction.
Specifically, assume that signature information of tx1 includes "7 days: multisign:3:2: public key 1: public key 2: public key 3: public key 4: sigdata1: sigdata2: sigdata 3"; wherein 7days is delay information; multiple sign is a multiple signature identifier; 3:2 is a multiple signature judgment rule, 3 indicates that 3 signature data are required to be obtained at least, public keys corresponding to the 3 signature data should be included in public keys 1-4, and 2 indicates that at least 2 signature data in the 3 signature data are correct; the public key 1, the public key 2, the public key 3 and the public key 4 are public keys of each first account which can manage a transaction initiator of delayed transaction, the sigdata1, the sigdata2 and the sigdata3 are signature data, in the current embodiment, it is assumed that the sigdata1, the sigdata2 and the sigdata3 are correct signature data, and the corresponding public keys are all included in the public keys 1 to 4;
since sigdata1, sigdata2 and sigdata3 are correct signature data and the corresponding public keys are all included in public keys 1 to 4, the multiple signature judgment rule of tx1 is met, and then the block chain nodes generate the first block according to tx 1.
In further embodiments, the multiple signature determination rules may also be configured according to actual requirements, for example, the multiple signature determination rules are configured to be 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 in the 3 signature data are correct, so that the same technical effect can be achieved.
It should be understood by those skilled in the art that when multiple signature information of a delayed transaction is configured in the signature information, the assets governed by multiple signatures may be not only assets in the delayed contract, but also assets of other contracts (i.e., the executor name of the delayed transaction is configured as other contracts outside the delayed contract), or global assets (i.e., the executor name of the delayed transaction is configured as null).
Further, when each first signature data in the first signature information does not accord with the multiple signature judgment rule, a packaging failure identifier is printed on the delayed transaction locally;
after a second length of time, the credentialing transaction is deleted locally.
In more embodiments, a policy for applying the packaging failure identifier may be configured according to actual requirements, for example, it is further necessary to determine whether the commission charge of the delayed transaction is sufficient or insufficient, and apply the packaging failure identifier to the delayed transaction locally.
It should be appreciated by those skilled in the art that the blockchain system may also be configured with a first interface for the user to query the status of the delayed transaction. When the state of the delayed transaction is found to be packaging failure, the user can resend the delayed transaction. And determining delayed transactions according to the first time and the first time length of the delayed evidence-storing transactions at the initial packaging time, and inquiring corresponding delayed evidence-storing transactions by the block chain link points according to the hash values of the delayed transactions when the block chain link points receive the delayed transactions again, wherein the block chain nodes can store the delayed transactions in the memory pool only when the block chain has the corresponding delayed evidence-storing transactions and the current time reaches the initial packaging time of the delayed transactions.
