Description

Technical Field

[0001] This invention belongs to the field of computer technology, and particularly relates to a consensus message identification method, device and storage medium based on self-expression. Background Technology

[0002] In existing technologies, cross-chain transaction execution results are synchronized using a bitmap, where each bit has only two states: 0 for failure and 1 for success. For example, if there's only one cross-chain transaction that failed, the failure status cannot be expressed, or if the highest bit represents a cross-chain transaction that failed. Current solutions filter all cross-chain transactions in the corresponding block on the main chain; if the corresponding bit for the cross-chain status is 0 or there is no status, it indicates a failure. In scenarios with numerous parachains, upgrading parachains is a significant headache. Users often don't want to upgrade parachain versions. Forced upgrades often impact their business operations. Summary of the Invention

[0003] This invention provides a consensus message identification method, device, and storage medium based on self-expression, and proposes a consensus message synchronization mechanism based on multiple versions of main chain and parallel chain. By marking the version number through the version identifier area, richer synchronization messages can be expressed.

[0004] To solve or partially solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] In a first aspect, the present invention provides a consensus message identification method based on self-expression, the method being applicable to main chain-parallel chain networks, the method specifically comprising:

[0006] The first consensus node generates the first consensus transaction to achieve consensus for the first block and configures the corresponding first consensus message. The first consensus message is used to synchronize the execution results of cross-chain transactions in the first block. The first consensus message includes a transaction identifier area, a status identifier area, and a version identifier area. The transaction identifier area includes several transaction identifier bits, and the number and order of the transaction identifier bits correspond one-to-one with the order of the number of cross-chain transactions in the block. The status identifier area is used to set the anchored transaction status. The status identifier area has a transaction success or transaction failure indicator. The transaction identifier bits in the transaction identifier area set the transaction status of the corresponding cross-chain transaction based on the transaction status anchored in the status identifier area. The version identifier area is used to set the version number corresponding to the parachain.

[0007] Preferably, the version identifier area is set to at least 2 bits, and the version identifier area expresses the version number in binary.

[0008] Preferably, the transaction identifier is followed by a transaction type identifier and an account address identifier. The account address identifier is used to mark the initiator address number of the corresponding cross-chain transaction, and the transaction type identifier is used to mark the transaction type of the cross-chain transaction.

[0009] Preferably, the transaction type identifier is set to at least 4 bits to express the transaction type of the cross-chain transaction in binary, and the account address identifier has a capacity of 32 bits.

[0010] In a second aspect, a computer device is provided, comprising one or more processors;

[0011] Memory, used to store one or more programs.

[0012] When the one or more programs are executed by the one or more processors, the one or more processors perform the method as described in the first aspect above.

[0013] Thirdly, a storage medium storing a computer program is provided, which, when executed by a processor, implements the method described in the first aspect above.

[0014] The beneficial effects of this invention are that by proposing consensus messages based on multiple versions of the main chain and parallel chains, it can express richer synchronization messages and support smooth upgrades of the main chain and parallel chains. It is compatible with both new and old versions of parallel chains. Attached Figure Description

[0016] The present invention will be further described clearly and in detail below with reference to specific embodiments and accompanying drawings. Those skilled in the art will be able to implement the present invention based on these descriptions. Furthermore, the embodiments of the present invention described below are generally only some embodiments of the present invention, and not all embodiments. Therefore, all other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort should fall within the scope of protection of the present invention. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Unless otherwise specified, the methods briefly described in the embodiments of the present invention are methods mastered by those skilled in the art.

[0017] As an embodiment of the present invention, a consensus message identification method based on self-expression is provided. The method is applicable to main chain-parallel chain networks, and the method specifically includes:

[0018] The first consensus node generates the first consensus transaction to achieve consensus for the first block and configures the corresponding first consensus message. The first consensus message is used to synchronize the execution results of cross-chain transactions in the first block. The first consensus message includes a transaction identifier area, a status identifier area, and a version identifier area. The transaction identifier area includes several transaction identifier bits, and the number and order of the transaction identifier bits correspond one-to-one with the order of the number of cross-chain transactions in the block. The status identifier area is used to set the anchored transaction status. The status identifier area has a transaction success or transaction failure indicator. The transaction identifier bits in the transaction identifier area set the transaction status of the corresponding cross-chain transaction based on the transaction status anchored in the status identifier area. The version identifier area is used to set the version number corresponding to the parachain.

[0019] Specifically, the version identifier area is set to at least 2 bits, and the version identifier area expresses the version number in binary.

[0020] Specifically, the transaction identifier is followed by a transaction type identifier and an account address identifier. The account address identifier is used to mark the initiator address number of the corresponding cross-chain transaction, and the transaction type identifier is used to mark the transaction type of the cross-chain transaction.

[0021] Specifically, the transaction type identifier is set to at least 4 bits to express the transaction type of the cross-chain transaction in binary, and the account address identifier has a capacity of 32 bits.

[0022] In this embodiment, the consensus message includes a cross-chain transaction setting, namely a transaction identifier area. The highest few bits correspond to cross-chain transactions, and the status of failed transactions can be clearly identified through these transaction bit settings. For example, a single transaction is represented as 10, where 1 represents one cross-chain transaction and 0 represents a failed transaction. 1010 represents three transactions, with 0 and 2 of them failing. This embodiment also includes a version number. For example, the version number has four bits: 0001 represents version 1, 0010 represents version 2, and a total of 16 versions can be represented.

[0023] By supporting versioned consensus messages, blockchain forks and smooth upgrades between the main chain and parachains can be reduced. In scenarios with a large number of parachains, upgrading them is a significant challenge. Users often don't want to upgrade their parachain versions. Forced upgrades can often disrupt their business. Adding versioned cross-chain transaction messages allows the main chain to support multiple versions of parachain consensus messages, enabling the simultaneous existence of both old and new versions and smooth upgrades.

[0024] This invention proposes a consensus message synchronization mechanism based on multiple versions of the main chain and parallel chains. By using consensus bitmap fields from multiple versions, richer synchronization messages can be expressed, such as status information or execution result information. This invention, by proposing a consensus message mechanism based on multiple versions of the main chain and parallel chains, can express richer synchronization messages and supports smooth upgrades of the main chain and parallel chains. It is compatible with both new and old versions of parallel chains.
