and C4: transaction records and stores, smart contracts record details of power transactions, including amount of power, price, participant identity, transaction time, and power quality data, records stored on blockchain to ensure security and non-tamper ability of data;
c5: the power transaction settlement, the smart contract automatically performs the settlement of the power transaction, including payment and receipt of money, and the settlement process may include transferring money from the buyer's account to the seller's account, using encrypted or traditional currency for payment.
5. The IPFS and blockchain based power transaction and access control scheme of claim 3, wherein: the power transaction system in the step B1 comprises a blockchain intelligent contract for paying and settling the power transaction, wherein the payment can be carried out by using encrypted currency or traditional currency, and the specific operation steps are as follows:
d1: generation of a payment request, after completion of the power transaction, the smart contract generates a payment request including information of the payer and the payee, and a payment amount, the payment request including a digital signature or other security verification to ensure validity and integrity of the request;
d2: the method comprises the steps of payment authorization and verification, wherein the intelligent contract verifies the validity of a payment request, and comprises the steps of verifying a digital signature and an identity, and authorizing an account of a payer to pay a corresponding amount when the payment request is valid;
d3: payment execution, the smart contract executing a payment, transferring money from the payer's account to the payee's account, the payment may be in the form of encrypted goods or conventional currency;
d4: payment records and stores, details of smart contract records payment, including payers, payee, payment amount, and payment time, the payment records being stored on the blockchain to ensure security and non-tamper resistance of data;
d5: payment confirmation and notification, the smart contract sends a payment confirmation notification to the payer and payee to inform that the payment has been successfully performed, which may be sent via email, text message, or other communication means.
6. The IPFS and blockchain based power transaction and access control scheme of claim 1, wherein: the power transaction system in the step B1 comprises a blockchain intelligent contract for supervision and compliance, and the specific operation steps are as follows:
e1: creating a supervision compliance contract, namely creating a special blockchain intelligent contract for a supervision organization to ensure that the intelligent contract can access the power transaction data and the supervision market, wherein the intelligent contract comprises an identity verification and authorization mechanism of the supervision organization to ensure that only legal supervision organizations can access the data;
e2: data sharing and monitoring, intelligent contracts automatically share specific power market data to regulatory authorities that use to monitor market operation and ensure compliance;
e3: report generation and submission, the smart contracts can generate standard reports or on-demand reports to meet the needs of regulatory authorities, the generated reports can include market operating conditions, power price trends, vendor activity information;
e4: compliance reviews, intelligent contracts allow regulatory authorities to conduct compliance reviews, including auditing whether the activities of participants are in compliance with regulations and policies, the results of which can affect marketing operations and policy formulation;
e5: security and privacy protection, the intelligent contracts ensure that the authorities can only access their authorized data, protecting the privacy of the participants, security measures including data encryption, authentication and access control.
