Example 2
A second embodiment of the present application provides a method for designing a power data management platform based on a blockchain, and the present application will be further described with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1-4, a power data management scheme based on blockchain technology includes the steps of:
s1: the functional architecture of the data management platform based on the block chain is designed.
The electric power block chain data management platform mainly adopts a alliance chain network architecture, namely, each admittance organization participating in the management platform can be allowed to join the alliance chain after being checked, and each organization respectively has a block chain node without a central node. All the participants share the whole data management platform through the whole alliance chain system, and the functions of releasing and storing the power data, trading and circulating the power data among organizations, transferring the power data and the like are realized through the data management platform, so that the use requirements of all the participants on the related power data are met.
The block chain data management platform has five main functions, namely data release, data circulation transaction, data transfer function, data right confirmation and data right control and supervision function.
(1) And (3) data release: each company block chain data management platform participant collects power data information in the local district and then distributes the data on a data management platform based on the block chain system.
(2) Data flow transaction: on a company blockchain data management platform based on a alliance chain, cross-department sharing circulation of data can be realized, and transaction of electric power data in the management platform is realized.
(3) Data transfer: after the two-party mechanism achieves a transfer agreement on certain electric power data, the original access right owner of the electric power data sends the own access right to the receiver in a transaction mode.
Unlike purchasing data from the original owner of the data in a data flow transaction, the original access owner will not hold the access to the data and will be transferred to the new purchaser. Meanwhile, after transfer, the node of the original publisher of the data can update the access right holder information of the data in real time according to the information on the chain, so that the data information can be checked only by the owner of the current access right.
(4) Data validation: the data generated on the blockchain network is provided with asset value after the data is authorized, and the circulation and the transaction of the data asset can be realized on the blockchain network.
The data can be validated, a data valuation model needs to be established, data are priced, and safe transaction circulation is facilitated. Blockchains are just the best technical vehicle for data capitalization. The biggest problem faced by data assets is unclear ownership, having the characteristics of "see through, copy, etc., which is the most essential distinction between data assets and ordinary merchandise. Blockchain technology enables data to be an asset, the most basic of which is that it can be validated. Unlike traditional internet data, the blockchain network can copy and distribute at will, can uniquely identify data assets, is not tamperable, can trace back, and can obtain consensus on the whole network in a decentralization manner. The blockchain encapsulates the data assets into data objects that can be uplinked, ensures asset uniqueness by a unique coding mechanism, and validates each data asset. Merging and splitting of data assets can occur in the circulation process, and the blockchain technology can ensure the continuity and traceability of rights. When the data source side and the processing side finish the actions of uplink, right confirmation, pricing, splitting and transaction through various assets by the blockchain technology, the uniqueness of the data assets can ensure that the data assets cannot be copied and tampered, and therefore the value of the data assets can be guaranteed.
(5) Data authority control and supervision: and managing rights of each organization participating node to join the alliance chain network, issue data, view and application of the data and the like.

Within the infrastructure layer, the system uses hardware facilities including dedicated devices, routers, and servers, which provide the underlying data storage environment for it, as well as forwarding and computing capabilities for the data.
Referring to fig. 1, a further four-layer architecture is shown.
Within the power data layer, the system uses hardware facilities including dedicated devices, routers, and servers, which provide the underlying data storage environment for it, as well as forwarding and computing capabilities for the data.

The service layer and the business layer provide services such as information certification confirmation, information verification, information examination, history tracing and supervision through interaction with the intelligent contract. The general functions of exchanging and sharing information, inquiring and searching the user and the like are realized.
S3: a blockchain-based data management platform transaction architecture is designed.
The data management platform transaction architecture takes the form of multiple chains in parallel.
The isomorphic multi-chain parallel transaction processing architecture consists of a blockchain platform and a client.
The client manages account information, periodically acquires the full-network latest state of the local account, and acquires the load information of the full-network blockchain when the transaction needs to be sent. The new transaction directly sent by the user is called as a logic transaction, the client divides the logic transaction into actual transactions through the decision of the load balancing module, and the actual transactions are sent to the transaction processing module of the corresponding subnet chain for parallel processing.
The blockchain platform is composed of a plurality of subnet chains, and each subnet chain has a globally unique network identification. Each subnet chain only needs to be responsible for transaction processing in the subnet, and the consensus process is independently completed.
The actual transaction processing process uses an atomic hash time lock contract built in a subnet, and the intelligent contract is automatically deployed when a chain is started so as to ensure the atomicity of one logic transaction when the logic transaction is executed on a plurality of subnet chains after being divided into a plurality of actual transactions. Meanwhile, assume that the quantifiable asset in each subnet chain is 1:1 to simplify the description of the architecture. In theory, the corresponding relation can be converted by adding other functional modules into the equivalent relation.
Referring to fig. 2, the subnet chain is composed of a plurality of nodes, and in the illustration, a "subnet transaction processing module", "a" network partition module "and a" data service module "are functional modules included in each node in the corresponding blockchain.
In the application, the client sends the transaction to the subnet chain transaction processing module, which means that the client sends the actual transaction generated by processing the logic transaction in the local transaction processing module to the nodes in each subnet chain, and the subnet transaction processing module of each node running the local program processes the corresponding transaction.
The detailed design of the client and blockchain platform (i.e., the subnet chain) is described in detail below.
(1) Client design
The client side mainly comprises three modules, namely account private key management, transaction data management and load balancing decision.
1) The account private key management module is responsible for generating and locally storing account private keys. Meanwhile, an Elliptic Curve Digital Signature Algorithm (ECDSA) and a Keccak-256 algorithm are used for obtaining the account address corresponding to the private key. Each user may have a different account, which may have assets on different chains.
2) The transaction data management module has the main functions of: the transaction data transmission module and the transaction data monitoring module. Wherein the transaction data transmission module may handle types of transactions including, but not limited to, multi-chain unidirectional transfers, compatible with DApp-type applications (i.e., stateful-type application transactions), aggregation and dispersion of assets (multi-chain bi-directional transfers), and the like.
3) The load balancing decision module is responsible for periodically inquiring the latest state of the local account to the data service module of each subnet chain and updating the local account information. Meanwhile, state information of the subnet chain needs to be maintained, including but not limited to current load, congestion degree, transaction fee, account registration condition and the like of the subnet chain, better transaction division decision is provided for a transaction processing module according to the demand of user transfer by combining on-chain information, user experience is optimized, and the purposes of transaction splitting, transaction fee selection, reduction of user waiting time and improvement of overall transaction processing rate of the network are achieved.
The inputs to the load balancing module include: the account balance of the transaction sender on each subnet chain, the transaction amount, the transaction fee and the throughput of the transaction pool in each subnet chain, the asset amount reserved on the subnet chain with the balance by the user, the transfer total of the current logic transaction, and the transaction completion time expected by the user. It should be noted that these inputs are currently proposed as parameters required by the decision process in the current case, and the parameters can be increased and decreased later according to the requirements. The load balancing module applies the inputs, runs an algorithm to obtain a plurality of combined schemes which can simultaneously meet the conditions of user expected time and payment cost, and returns the transaction splitting strategy with the minimum cost to the transaction data sending module. The execution process diagram of the load balancing module is shown in fig. 3.
(2) Blockchain platform design
The blockchain platform, namely the subnet chain, is responsible for receiving and executing related transactions of account state change in the specific network, maintaining the latest state of the account in the specific network, and providing the latest account state information in the network space for the upper layer application. In the normal operation process of the system, a 'subnet transaction processing module' of the subnet chain receives transactions sent by a client according to a network division rule, calls different function functions aiming at different transaction types, and completes a consensus process in each subnet. Wherein the supported transaction types correspond to the supported transaction types in the client, including but not limited to multi-chain unidirectional transfers, compatible with DApp-type applications, aggregation and dispersion of multi-chain assets. The data service module monitors the latest state of the subnet chain in real time, updates the internal storage and provides an on-chain state query interface for the upper layer application.
1) Subnet transaction processing module
The subnet transaction processing module of the subnet chain receives the subnet transaction sent by the client. First, the basic information of the transaction (type of transaction, whether source account assets are sufficient, whether there is a "double attack" etc.) is checked. If the check is passed, the transaction is added to a local transaction pool (a cache structure of the transaction to be executed), and the transaction is selected and packaged. If the check is not passed, a message of "transaction execution failure" is returned to the client, and the transaction is discarded, and the architecture is shown in fig. 4.
The transaction verification module only receives transaction types supported by the current system, and the verification information comprises the transaction types, whether source address balances are sufficient and the like. If the check is passed, the transaction is added to the processing array of the corresponding transaction type, and a transaction receipt message is returned to the client transaction processing module. If the test is not passed, a transaction error message is returned to the client transaction processing module. The subnet transaction processing array stores the transaction to be processed on the corresponding subnet chain, and the transaction processing array is packed according to the transaction fee selection.
The multi-type transaction processing module is responsible for processing different types of transactions, each type of transaction is also different in consideration of the processing process due to different functionalities, and the processing process is respectively described in a sub-functional module of 'multi-chain unidirectional transfer', 'DApp application compatibility', 'aggregation and dispersion of assets', and it is noted that the functions represent a relatively general class of functions, and if other business requirements exist, other functional modules can be deployed in an increased mode, so that the expandability of the system is realized.
2) Network partition module
The application uses a relatively simple and efficient network division rule, and can support the extension of the subnet chain according to the requirement. Unlike prior art transactions that are partitioned by user address space, each subnet chain in the architecture has a unique network identifier (id) that grows strictly linearly. When a client builds a new transaction, the transaction is sent to multiple sub-network chains according to the client's load balancing module, so it is entirely up to the client on which chain the transaction is executed. The slicing module of the blockchain platform is mainly responsible for the management of the subnet chain, including numbering the chain, adding a new chain and the like. When existing blockchain systems have reached saturation, increasing the subnet chains in order to meet the ecological needs of the blockchain requires a determination to increase the number of chains. Because upgrades to the system require community consensus, the decision rule to increase the number of chains is critical. If the number of chains is excessively small, it is necessary to consider the relationship between the benefit and the cost for achieving consensus. If the number of the links is increased too much, the ecological stability of the blockchain can be damaged, the application does not limit the specific number, and the subnetwork links can be increased linearly according to specific business and application scene settings at the later stage, thereby providing stability.
When the system is started, N subnet chains are assumed to be started at the same time, and the initial asset on the subnet chains is 0; blocks are continuously generated while the native asset is released.
Each application provider can deploy an application on a target subnet chain according to the requirement of the application, wherein the requirement of the application refers to the funds circulation degree required by the application provider when the application is expected to run, and the funds circulation degree comprises real-time flowing speed of assets and total amount of assets in the subnet chain, and the aim is that the application has enough assets to run efficiently. The release of the application can improve the activity of the blockchain ecology and increase the circulation of the asset. The speed of asset distribution is determined, when the asset circulation speed required by the application is far greater than the distribution speed, the conditions of overheating application, overweight load and unsmooth asset circulation can be generated on the subnet chain, so that the side effects of chain congestion, transaction fee increase, user experience reduction and the like are caused, and at the moment, a new subnet chain needs to be added to share the load of the original subnet chain. When the new chain is started, a freezing period is needed to meet the asset requirements of the application, so that the amount of assets in the new chain is at least not less than the requirements of the application to be shared. When the freezing period is over, the application provider decides whether to deploy the application according to the state of the original link, and migrates the business of the original subnet link, wherein the migration refers to the fact that the user performs the business in the application of the new subnet link, as in the application using the original subnet link.
3) Data service module
The subnet chain data service module provides complete account state information, chain information and the like for upper-layer applications by tracking state changes on the chain. Transactions are specifically handled in the sub-functional modules of "multi-chain unidirectional transfer", "DApp-like application compatibility", "aggregation and dispersion of assets". The core content contained in the transaction data is transaction behavior initiated by a sender to a receiver, and a typical data structure contained in the transaction data is as follows: "source address a", "destination address B", "transfer amount V", "transaction number N", "transaction Input", "transaction type", "other". The address is the last 160 bits (20 bytes) of the hash value obtained by the public key through the Keccak-256 algorithm in the asymmetric key technology.
