“…In order to achieve a recovery of the channels approaching the end of liquidity, [17] proposes OPRE (OPtimal off-chain REcovering of payment channels), which recovers the maximum number of nearly exhausted channels in a PCN, transforming the remaining channel tokens into cheaper off-chain payments in respect to those initially defined. In addition, the OPRE protocol provides a privacy preserving version design, which does not require a Trusted Third Party (TTP).…”

The development of e-commerce applications, involving small-value transactions for the exchange of goods or services introduces notable security and privacy challenges. Micropurchases, commonly referred to as micropayments, offer a pragmatic solution that provides a balance between efficiency and security for small-value transactions. The increasing demand for this payment approach, particularly with the advent of technologies such as the Internet of Things (IoT), underscores the need for innovative solutions.This paper introduces a novel micropurchase protocol making use of transferable payment channels. The protocol facilitates equitable and fair exchanges betweenminimal monetary units (μ-coins) and desired goods or services, allowing efficient payments of low values. The proposed transferable channels enable off-chain transactions, minimizing the reliance on on-chain transactions to achieve essential security features. The protocol defines the process of performing purchases, handling received payments, incorporating functionalities for the transfer and reutilization of payment channels for both customers and merchants. Furthermore, the proposed scheme specifies the procedures for redeeming the earned μ-coins by the merchant and refundingthe unused μ-coins by the customer.
