什么是 Sign?

Sign Protocol is an omni-chain attestation protocol that enables users to create, store, and verify attestations across multiple blockchain networks. By leveraging zero-knowledge cryptography and digital signatures, Sign ensures that all attestations are secure, verifiable, and tamper-resistant.
With $28.65 million in funding from leading investors including Sequoia Capital, HashKey Capital, and YZi Labs (formerly Binance Labs), Sign Protocol is rapidly emerging as a foundational layer for trust and interoperability in the blockchain ecosystem.
