PayPIN-centric Web3 Payment Ecosystem

PayPIN applies blockchain technology to payments through integrated hardware. It consolidates a chain abstraction layer, a unified payment protocol, a cross-chain clearing network, and a decentralized identity system, bringing the benefits of blockchain to real-world payment scenarios.

Chain Abstraction Layer

PayPIN's chain abstraction layer, using the adapter pattern, hides underlying blockchain details and provides a unified payment interface. It standardizes cross-chain APIs, simplifies development, ensures multi-network compatibility, and offers more options.

Unified Payment Protocol

PayPIN establishes a unified payment protocol that defines transaction formats, signature verification, and error handling standards, ensuring interoperability between blockchains.

Cross-Chain Clearing Network

PayPIN's cross-chain network, using state channels, enables fast, secure, low-cost transfers between blockchains. It supports multiple off-chain transactions, recording the final state only when channels close, enhancing speed and reducing gas.

Decentralized Identity System (DID)

PayPIN integrates W3C DID standards, enabling users to create and manage digital identities. DID allows user authentication without revealing sensitive information. The system supports various authentication methods (biometrics, cryptographic signatures) and uses zero-knowledge proofs for privacy.
