S12: Generate a delayed transaction, and generate a delayed certificate deposit transaction according to the delayed transaction; wherein, the payload field of the delayed certificate deposit transaction includes the delayed transaction, and the delayed transaction includes the delayed information;

S14: Send the delayed certificate transaction to the blockchain network for the blockchain nodes to:

Specifically, the delayed information is taken as a fixed time; the first signature information of the delayed transaction includes the delayed information of the delayed transaction; when it is determined that the delayed deposit transaction is the first type of transaction that needs to be delayed, the delayed transaction is deducted. The handling fee for the time-delayed certificate transaction includes: according to the name of the executor of the delayed deposit transaction, it is determined that the delayed deposit transaction is the first type of transaction that needs to be delayed, and the handling fee of the delayed deposit transaction is deducted as an example; The delayed transaction is tx1, the delayed deposit transaction is tx2, the payload field of tx2 includes tx1, and the delayed information is a fixed time, assuming that it is 0:00:00 on January 1, 2021;

The client performs step S12, generates tx1, and generates tx2 according to tx1;

The client performs step S14, and sends tx2 to the blockchain network;

The blockchain node judges that tx2 is the first type of transaction that needs to be delayed according to the executor name delay of tx2, the blockchain node deducts the handling fee of tx2, and stores the tx2 certificate on the blockchain;

The blockchain node stores tx1 locally, and the delay information in the signature information of tx1 determines the starting packaging time of tx1, which is 0:00:00 on January 1, 2021;

When it reaches 0:00:00 on January 1, 2021, and the blockchain node A has the packaging right of the latest block after the above time, the above block is generated according to tx1;

A broadcasts the above block to other blockchain nodes, and other blockchain nodes delete the local tx1.

In this embodiment, the delay information is taken as a fixed time; the first signature information of the delayed transaction includes the delay information of the delayed transaction; when it is determined that the delayed certificate deposit transaction is the first type of transaction that needs to be delayed, the delayed transaction is deducted. The handling fee for the time-delayed certificate transaction includes: according to the name of the executor of the delayed deposit transaction, it is judged that the delayed deposit transaction is the first type of transaction that needs to be delayed, and the handling fee of the delayed deposit transaction is deducted. The delayed transaction generation method of .

In more embodiments, the delay information can be configured according to actual needs, for example, it is configured to be the first time period that needs to be extended for the delayed transaction. Correspondingly, the method for calculating the starting packaging moment of the delayed transaction should also be based on the actual situation. The configuration is performed, for example, as follows: the initial packaging time of the delayed transaction is determined according to the first moment and the first duration when the delayed deposit transaction is packaged, so that the same technical effect can be achieved.

In more embodiments, the delay information of the delayed transaction may also be configured in other fields according to actual requirements. Those skilled in the art should understand that when the delay information of the delayed transaction is configured in the signature information, the assets delayed in the delayed transaction can be not only the assets in the delayed contract, but also the assets of other contracts (that is, The executor name of the delayed transaction is configured as a contract other than the delayed contract), or the global asset (that is, the executor name of the delayed transaction is configured as empty).

In more embodiments, the method of judging whether the delayed certificate deposit transaction is the first type of transaction that needs to be delayed can also be configured according to actual needs. Hash value, perform hash operation according to the name of the executor of the delayed certificate transaction to obtain the hash value', and judge whether the above hash value is the same as the above hash value' to determine whether the delayed certificate transaction needs to be delayed The first type of transaction can achieve the same technical effect.

The above-described embodiments enhance the security of the blockchain network.

Preferably, when it is determined that the delayed certificate deposit transaction is the first type of transaction that needs to be delayed, the deduction of the handling fee for the delayed certificate deposit transaction includes:

According to the name of the executor of the delayed certificate deposit transaction, it is judged that the delayed certificate deposit transaction is the first type of transaction that needs to be delayed, and the handling fee of the delayed certificate deposit transaction is deducted.

For the generation principle of the delayed transaction in the foregoing embodiment, reference may be made to the method shown in FIG. 1 , which will not be repeated here.

In the scheme shown in Figure 1, if the blockchain node A does evil and packs tx1 into the block in advance, other nodes cannot verify whether tx1 is packaged after a sufficient period of time. The above mechanism will cause the assets of the transaction sender of tx1 to be insecure.

Aiming at the above problems, can be solved by the following embodiments:

Preferably, the delay information is the first time length required to extend the delayed transaction; storing the delayed transaction locally, and determining the initial packaging time of the delayed transaction according to the delay information includes:

Determine the initial packaging time of the delayed transaction according to the first moment and the first duration of the delayed transaction being packaged;

Store the delayed transaction locally, and store the first correspondence between the first hash value of the delayed transaction and the second hash value of the delayed transaction;

Among them, the first correspondence is used for other blockchain nodes:

When executing the delayed transaction, the delayed certificate deposit transaction is found according to the second hash value, and the starting packaging time of the delayed transaction is determined according to the first moment when the delayed certificate deposit transaction is packaged and the first duration;

Determine whether the packaging time of the delayed transaction is not earlier than the initial packaging time:

No, the delayed transaction execution is unsuccessful.

Specifically, it is assumed that the first moment when tx2 is packaged is 0:00:00 on November 24, 2020, the first duration is 7 days, and the generation time of the block generated by A is 0:00 on December 30, 2020: 00;

The blockchain node determines the starting packaging time of tx1 according to the time when tx2 was packaged at 0:00:00 on November 24, 2020 and 7 days, and the starting packaging time of tx1 is at 0:00:00 on January 1, 2021 ;

The blockchain node stores tx1 locally, and stores the correspondence between hash(tx2) and hash(tx1);

When other blockchain nodes receive the block generated by A, when tx1 is executed, they will find tx2 according to hash(tx1), and according to the time when tx1 was packaged at 0:00:00 on November 24, 2020, the first duration 7 days to determine the starting packing time of tx1, the starting packing time of tx1 is 0:00:00 on January 1, 2021;

Other blockchain nodes judge whether 0:00:00 on December 30, 2020 is not earlier than the start packaging time at 0:00:00 on January 1, 2021;

Since 0:00:00 on December 30, 2020 is earlier than the start packaging time at 0:00:00 on January 1, 2021, other blockchain nodes fail to execute tx1.

Since most nodes fail to execute tx1, the erroneous block generated by blockchain node A will become a block on the side chain, which ultimately ensures the security of the assets of the transaction sender of tx1.

Preferably, the first signature information of the delayed transaction includes the delayed information of the delayed transaction.

Further, the delayed transaction is a multi-signature transaction, and the first signature information includes a multi-signature identifier, the first public key of each first account that can manage the transaction initiator of the delayed transaction, and the first multi-signature can be successfully executed. The multi-signature judgment rule for signed transactions, the first signature data obtained by several second accounts signing the transaction content of the delayed transaction according to the private key held, and the generation of the first block according to the delayed transaction includes:

Determine whether each first signature data in the first signature information conforms to the multi-signature judgment rule:

If yes, then generate the first block according to the delayed transaction.

Specifically, it is assumed that the signature information of tx1 includes "7days:multisign:3:2: public key 1: public key 2: public key 3: public key 4: sigdata1: sigdata2: sigdata3"; wherein, 7days is delay information; multisign is Multi-signature identification; 3:2 is the multi-signature judgment rule, 3 means that at least 3 signature data need to be obtained, the public key corresponding to the three signature data should be included in public key 1 to public key 4, 2 means that the three signature data are included in At least two signature data are correct; public key 1, public key 2, public key 3, and public key 4 are the public keys of each first account that can manage the transaction initiator of the delayed transaction, sigdata1:sigdata2: sigdata3 is 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 included in public key 1 to public key 4;

Since sigdata1:sigdata2:sigdata3 are all correct signature data, and the corresponding public keys are included in public key 1 to public key 4, which conforms to the multi-signature judgment rule of tx1, the blockchain node generates the first block according to tx1.

In more embodiments, the multi-signature judgment rule can also be configured according to actual requirements. For example, it is configured as 3:50%, where 3 means that at least three signature data need to be obtained, and 50% means that at least 3 signature data need to be obtained. 2 signatures (round up of 1.5) data is correct and achieves the same technical effect.

Those skilled in the art should understand that when the multi-signature information of the delayed transaction is configured in the signature information, the assets controlled by the multi-signature can be not only the assets in the delayed contract, but also the assets of other contracts (that is, the delayed transaction The executor name is configured as a contract other than the delayed contract), or the global asset (that is, the executor name of the delayed transaction is configured as empty).

Further, when each of the first signature data in the first signature information does not conform to the multi-signature judgment rule, the delayed transaction is marked with a packaging failure mark locally;

After the second time period, the deposit certificate transaction is deleted locally.

In more embodiments, the strategy of marking the packaging failure flag can also be configured according to actual requirements. For example, it is necessary to judge whether the handling fee for the delayed transaction is sufficient or not, and the delayed transaction is marked with the packaging failure flag locally.

Those skilled in the art should be able to associate that the blockchain system can also be configured with a first interface for the user to query the status of the delayed transaction. When the status of the delayed transaction is found to be package failure, the user can resend the delayed transaction. The initial packaging time is determined by determining the delayed transaction according to the first moment and the first duration of the delayed certificate transaction being packaged, and when the blockchain node re-receives the delayed transaction, the blockchain node will determine the delayed transaction according to the delayed transaction. Only when there is a corresponding delayed certificate transaction on the blockchain and the current moment has reached the initial packaging time of the delayed transaction, the blockchain node will delay the transaction. When the transaction is stored in the memory pool.

S27: When the initial packaging time is reached and the packaging right of the latest first block after the initial packaging time is reached, the first block is generated according to the delayed transaction;

S29: Broadcast the first block to other blockchain nodes so that other blockchain nodes can delete the local delayed transaction.

For the execution principle of the delayed transaction in the above embodiment, reference may be made to the method shown in FIG. 1 , which will not be repeated here.

Preferably, the delay information is the first time duration required to extend the delay transaction; the delay transaction is stored locally, and the initial packaging time of the delay transaction determined according to the delay information includes:

Among them, the first correspondence is used for other blockchain nodes:

When the delayed transaction is executed, the delayed certificate deposit transaction is found according to the second hash value, and the initial packaging time of the delayed transaction is determined according to the first moment when the delayed certificate deposit transaction is packaged and the first duration;

If yes, delete the local delayed transaction.
