Pay Protocol is a cryptocurrency payment platform for both e-commerce and retail use. It is a project supported by Danal, a payment company based in South Korea. By combining Danal's 20 years of experience in payments with blockchain technology, Pay Protocol aims to mitigate the pain points of traditional payment systems, mainly excessive intermediary processes and high fees caused by them and slow payment schedules.
PayProtocol has been developed on Hyperledger Fabric (HLF). Unlike general blockchain where unspecified people participate in data processing, HLF is a private blockchain where only authorized node can join the network. It ensure fast transaction and excellent privacy which makes it best suited for payment services.
