Proofi

Proofi is a decentralized identity solution built by LTO Network that focuses on providing KYC/AML verification services for DeFi protocols while preserving user privacy. Launched in 2022, the platform implements the W3C DID and Verifiable Credentials specifications through LTO Network's identity node infrastructure. The system's core technical innovation is its ability to provide simple yes/no attestations about user eligibility without sharing the underlying personal data, enabled through integration with the Chainlink oracle network for cross-chain compatibility.

The platform's architecture includes several key technical components:

• Identity Nodes that support W3C DID standards
• Smart Contract Integration via Chainlink Any API
• Cross-chain Verification capabilities
• OpenID Connect authentication support
• Timestamped and signed verification responses

Notable implementations include a public beta launched in 2023 demonstrating KYC verification for NFT minting based on geographic location. The platform maintains a closed trust network of identity providers, with proofi.com serving as the default provider during the beta phase. While primarily targeting DeFi protocols, exchanges, and marketplaces, Proofi aims to reduce the regulatory compliance burden for Web3 projects while protecting user privacy through its "verify-once, use-anywhere" approach to digital identity verification.
