Blockchains are a type of distributed ledgers or shared databases. The data stored in the blockchain has the following characteristics: transparency, collective maintainability, non-modifiable, traceability are disclosed. From a data perspective, a blockchain is a nearly non-tamperable distributed data whose distributed nature is manifested not only in the distributed storage of the data, but also as a distributed record of the data. From the technical aspect, the blockchain technology is a result of the common integration of multiple technologies and is not a novel single technology. These techniques are integrated together by a new formal structure that constitutes a new data structure for recording and storing data. Each block consists of a block head and a block body. The block header typically contains some basic information of this block, such as version number, record of the previous block, root value of Merkle tree, timestamp, target feature value, random number, etc. The block consists of transactions that are signed by the user using a private key and verified using a public key. Merkle Hash trees are typically used to generate Hash values for all transactions in this block to reduce the chain's storage overhead. One block also contains the hash value of the previous block to link the two blocks together.
Referring to fig. 1, the embodiment of the application provides a blockchain-based power data cross-domain supervision system, the blockchain network includes a central chain 1 composed of control center stations of a power system, a source chain 3 composed of production service departments of the power system, a target chain 4 composed of management departments of the power system, and communication nodes, a monitoring node module 2 is disposed on the central chain, the monitoring node module 2 is connected with the source chain 3 composed of the production service departments of the power system and the target chain 4 composed of the management departments of the power system,
the monitoring node module 2 scans the blocks to capture cross-chain events and traverse the generation of newly added blocks;
the blockchain network adds a cross-domain event identifier to the captured cross-chain event based on the event;
the communication node finds a corresponding event according to the identifier, obtains data of the event in the cross-link request, packages time parameters of the data and the block, signs the data by using a private key of the node, and uploads the data to a central chain for consensus contract audit verification;

As shown in fig. 2, the embodiment of the present application provides a blockchain-based power data cross-domain supervision method, which includes the following specific steps,
the monitoring node module scans the blocks to capture cross-chain events and traverse the generation of newly added blocks;

the communication node of the blockchain network finds a corresponding event according to the cross-domain event identifier, obtains data of the event in a cross-domain request, packages time parameters of the data and the block, signs the data and the time parameters of the block by using a private key of the node, and uploads the signature to a central chain for consensus contract audit verification;

Various types of cross-chain transactions are agreed upon at the time of system initialization, and a cross-domain event identifier is allocated for different scheme types. When the user side initiates a cross-link request to the blockchain network, the blockchain network adds a cross-domain event identifier to the event according to the set allocation rule.
Cross-domain event identification is a function specific to the blockchain framework, and in smart contracts declaratively identifying event types and content specific smart contract decision schemes are agreed upon when co-compiling the contracts.
The monitoring node captures cross-chain events by sequentially scanning the blocks, where the events are specific transactions of the blockchain processing, and traverses the generation of new blocks. Equivalent to an independent contract call, and the traversed blocks are ordered in time by order nodes. And analyzing the event according to the event identification by analyzing the block structure, and sending the event to the communication node. Because the block is a fixed data structure model, the nested structure of the outer layer of the block is directly disassembled according to the data offset to obtain an EVENT list, each EVENT has an EVENT dictionary, and the EVENT attribute found in the EVENT dictionary is the EVENT identifier. The communication node finds the corresponding event according to the identification, obtains the data of the event in the cross-link request, such as the parameters required by the application file or the returned file storage address, the digital certificate of the transaction initiator and the like, packages the data with the time parameters of the block, uses the private key of the node itself to sign the data and uploads the data to the central link,
after the detection of the consensus contract, the consensus contract verifies the electronic signature to ensure that the data is not tampered, verifies whether the user certificate is outdated according to the unique user identifier of the transaction initiator, and finally writes the consensus information onto the block to perform uplink block-out.
The central chain sends the data consensus information to the target chain according to the auditing result of the consensus contract, so that the behavior of the event is synchronously stored on the target chain, the source chain and the target chain reach consensus, and the target chain can be provided with the functions of cross-chain tracing and anomaly discovery.
The consensus contract ensures that all chain stored trace-source data are consistent from time to time and cannot be modified randomly by a single node. In the central chain, when a cross-chain transaction passes through the central chain, the blockchain network of the central chain traces all the actions of making changes to the digital certificate and the event identifier of the transaction through a consensus contract, and checks with the data transferred by the transaction to judge whether the actions such as abnormality, data tampering and the like occur.
Under the condition that the system provided by the invention is used as a block chain cross-domain supervision system based on attributes, a cross-chain technology is utilized to build a central chain, the abnormal condition is detected through a consensus contract and then transmitted to a target chain, and the functions of cross-chain circulation audit, tracking tracing, abnormal discovery and the like are provided through the central chain.
The system is applied to the requirements of cross departments and cross mechanisms in the intelligent power grid, namely that the data and account book isolation requirements exist for the two parties, the data of the two parties are arranged in two block chains, the two chains have complete transaction processing capacity, and the request and the execution result of the cross-chain transaction are transmitted and commonly recognized in a cross-chain mode of a side chain.
For example, the system is used for a smart grid scene, the department a initiates a transaction to the department b, firstly sets a transaction list file, encrypts by using the attribute combination of the department b as an attribute encryption strategy, and then initiates a cross-chain request. The central chain consensus the file to the block based on the audit result and sends the request to the block chain where the b department is located. And b, checking the file data and the identity information in the request by using the hash value of the identity public key of the a department and the file, decrypting the file by using the attribute private key of the b department after the identity public key and the identity information of the a department are not tampered, and judging whether to accept the transaction according to the content of the transaction list. If not, a rejection message is returned directly. And (3) modifying the electronic data of the money or goods stored in the department b after the transaction is accepted, and returning the modification to the department a. The central chain can share the modification behaviors of the department b and synchronously store the data modification behaviors of the departments a and b on the central chain. The a department checks the reliability of the source of the message data returned by the b department according to the identity public key of the b department, and then modifies the data and consensus the behavior to the central chain. If a party misreports data, a central chain in broadcasting can find that the self-stored modification behavior is inconsistent with the modification behavior of the block chain where the a department or the b department is located, the central chain can set abnormal information, and contracts on the central chain can trace back the modification behavior of the data to find out which data modification behavior is inconsistent.
