The payment system, at the request of the participating node, performs a loan for the channel deposit for creating a payment channel to the participating node, or a loan node that performs a loan for the capital to the participating node that needs to perform prepayment for payment ; Among the participating nodes, the trading party nodes deposit a channel deposit for a P2P transaction and create a P2P payment channel, and the trading party nodes perform a P2P transaction through the P2P payment channel, or the intermediary nodes among the participating nodes for payment Pay in advance for the price. A node of a transaction that lacks a channel deposit or an intermediary node that lacks capital for prepayment can apply for a loan to the loan node to obtain a channel deposit or capital from the loan node, thereby enabling transactions between users.
