Abstract

Cryptocurrency has limitations to be used as an actual payment method due to the scalability problem of the blockchainconsensus protocol, and various off-chain solutions to solve these limitations are being studied. In this paper, we design anefficient off-chain payment channel using one-way hash function and implement the designed payment channel usingEthereum smart contract. In addition, the experiment was conducted to measure and analyze execution time and cost foreach method by deploying it in the same environment as the previously implemented plasma MVP. As a result, comparedwith plasma MVP, the proposed solution was able to reduce the total cumulative time by about 34% and reduce the overallexecution cost by about 41%.
