Blockchain-based payment control method and apparatus, and device and medium

An electronic device, comprising:

• one or more processors;
• and
• a storage apparatus for storing one or more programs, wherein the one or more programs, when executed by the electronic device, cause the electronic device to implement a blockchain-based payment control method, the method comprising:
• determining a securities account available for payment based on a binding request for a securities account initiated by a requester;
• transmitting the securities account available for payment to the requester to receive securities account selection information fed back by the requester for the securities account available for payment, to obtain a to-be-bound securities account;
• establishing a payment link with the to-be-bound securities account, the payment link being used to invoke the securities account to use fund in the securities account;
• verifying a payment request for a securities account initiated by the requester, wherein the payment request comprises a payment amount and a payee;
• in response to the payment request passing the verification, performing fund deduction on the securities account based on the payment amount through the payment link, deducting a quota corresponding to the payment amount from a payment quota corresponding to the requester, and instructing an auxiliary payment platform to transfer the payment amount to the payee;
• transferring funds corresponding to the payment quota to the auxiliary payment platform to generate a transaction result;
• and
• verifying the transaction result through a smart contract and uploading data generated during the payment to a blockchain in response to the transaction result passing the verification.
