xLumi: Payment Channel Protocol and Off-chain Payment in Blockchain Contract Systems
This addresses the need for efficient and secure payment channels in blockchain networks, though it appears incremental as it builds on existing concepts like unidirectional and bidirectional channels.
The paper tackles the problem of secure off-chain payments in blockchain systems by introducing xLumi, a payment channel protocol that guarantees fund security through simple mathematical rules, with implementation details provided for V Systems contract systems.
In this paper, we introduce Super Luminal ("xLumi"), a new payment channel protocol for blockchain systems. xLumi is a simple unidirectional payment channel that can be extended to a bidirectional payment channel or a complete network. xLumi guarantees the security of the payment channel's funds by using a simple set of mathematical rules that can be easily implemented on any blockchain with the necessary infrastructure. We also give the detailed implementation methods of this idea using V Systems contract systems in this paper.
