Sign Protocol is an omni-chain attestation protocol designed to allow users to create, store, and verify attestations across multiple blockchain networks. By leveraging zero-knowledge cryptography and digital signatures the protocol ensures that attestations are secure, verifiable, and tamper-resistant.
The project has secured $28.65 million in funding from major investors such as Sequoia Capital, HashKey Capital, and YZi Labs (formerly Binance Labs), solidifying its position in the blockchain ecosystem.
Activity Details
Currently the Sign Protocol airdrop campaign is underway offering users a chance to earn potential rewards by participating in simple on-chain activities.
