Problems solved by technology

[0003] The current block and transaction verification performance loss is huge, mainly reflected in: each block and each transaction and all proposals and endorsements are verified by signature and identity certificate signature chain, resulting in low overall verification efficiency. It is not conducive to R&D efficiency and system stability

Embodiment 1

[0035] The technology of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Such as figure 1 As shown, the present invention proposes a block chain verification method that realizes block chain tamper-proof, and the specific implementation steps include:

[0036] Step1: Configure different national secret algorithm verification directory configurations through the national secret adapter and its components to read the specified block ledger file, perform preliminary verification on the ledger file, and obtain the corresponding blockchain information. The blockchain information Including block information, transaction information and signature information on the chain, the signature information includes the signature of the block file and the certificate issuance chain associated with the block file;

[0037] Wherein, the verification method also supports the National Secret Algorithm, which is a series...

Embodiment 2

[0057] The block verification includes:

[0058] 1) previousHash check, verify that the previousHash of the current block is equal to the hash value calculated from the previous block;

[0059] 2) Hash verification, verify that the hash of the current block is equal to the hash value calculated by the current block;

[0060] 3) Check the latest configuration block, verify that the blockNumber value of the latest configuration block of the current block is less than or equal to the blockNumber value of the current block;

[0061] 4) metaData (metadata) verification, verify each signature of metaData[0] under the current block, and verify its certificate signature chain;

[0062] The transaction verification includes:

[0063] 1) Transaction certificate signature chain verification, verifying the certificate signature chain of each transaction;

[0064] 2) Transaction signature chain, verifying the signature of each transaction;

[0065] 3) Transaction proposal and multiplie...

Abstract

The invention discloses block chain verification, a storage medium and a device for realizing tamper-proofing of a block chain. The method comprises the steps: configuring different national secret algorithms through a national secret adapter and a component thereof, verifying directory configuration, reading a specified block account book file, carrying out the preliminary verification of the account book file, and obtaining the corresponding block chain information; analyzing the block chain information and selecting a specified chain type mode for verification; the national secret adapter is configured with a plurality of plug-ins to obtain and compare various types of verification results, and meanwhile, multiple files are verified, so that the integrity and correctness of block chain information are ensured, the tamper-proofing of the block chain is realized, and the verification results are divided into multiple files due to the fact that an account book becomes larger, therefore, the verification results are obtained through the plurality of plug-ins, and each plug-in obtains the corresponding file, so that the verification efficiency is improved. And the research and development efficiency and the system stability are improved.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to a block chain verification method, a storage medium and a device for realizing tamper-proof block chains. Background technique [0002] In order to ensure the legality of the transaction and the security of the entire system, the blockchain will perform various checks during operation, among which the block tamper-proof check is the integrity, signature, and signature of the block and its transactions. chain verification. [0003] The current block and transaction verification performance loss is huge, mainly reflected in: each block and each transaction and all proposals and endorsements are verified by signature and identity certificate signature chain, resulting in low overall verification efficiency. It is not conducive to research and development efficiency and system stability. [0004] Therefore, there is an urgent need to implement a new blockchain veri...
