3. The method for power data storage based on the intelligent block chain contract as claimed in claim 2,
when the contract is called, firstly searching the access authority list, if the contract account address is in the list, executing contract logic according to the triggering condition and the response rule, and operating the distributed evidence storage function; if the set condition of the list is not satisfied, the contract invocation fails.
4. The method for storing electric power data based on the intelligent block chain contract as claimed in claim 3, wherein the access authority list is updated in real time.
5. A power data storage system based on blockchain intelligent contracts, comprising:
an acquisition module: for obtaining power data;
a compiling module: the intelligent contract compiling device is used for compiling the power data into contract codes through a Solidity programming language and reaching the intelligent contract compiling device through web3.js, and the intelligent contract compiling device generates EVM byte codes and contract binary executable codes;
a contract feedback module: the system is used for feeding back EVM byte codes and contract binary executable codes to a front end;
a contract deployment module: the system comprises a node cluster, a transaction hash module, an application program binary interface and a server, wherein the node cluster is used for deploying the compiled content of a contract on the established node cluster and packaging the compiled content of the contract to the transaction hash and the application program binary interface on a block chain;
an address feedback module: after the contract is successfully deployed, feeding back a contract account address to the front end;
the intelligent contract calling module: the intelligent contract processing system is used for calling an intelligent contract at the front end and realizing interaction with the intelligent contract through a contract account address, an application program binary interface and a nonce, wherein the nonce refers to a transaction number, and an automatic numerical value is increased by one after the intelligent contract is called each time.
6. The power data storage system based on the blockchain intelligent contracts according to claim 5, further comprising:
and the adding authority module is used for adding the contract account address to an access authority list of the contract.
7. The power data storage system based on the blockchain intelligent contracts according to claim 6, further comprising:
a retrieval permission module: the contract management system is used for searching the access authority list when a contract is called, and executing contract logic and running a distributed evidence storing function according to a trigger condition and a response rule if a contract account address is in the list; if the set condition of the list is not satisfied, the contract invocation fails.
8. The power data storage system based on the blockchain intelligent contracts according to claim 6, further comprising:
an update module: for updating the access rights list in real time.
9. An electronic device, comprising:
a memory for storing one or more programs;
a processor;
the one or more programs, when executed by the processor, implement the method of any of claims 1-4.
10. A computer-readable storage medium, on which a computer program is stored which, when being executed by a processor, carries out the method according to any one of claims 1-4.
