On January 28, 2025, YZi Labs, the newly rebranded arm of Binance Labs, announced an investment in Sign Protocol, a blockchain-based token airdrop service, amounting to $16 million. The funding was supported by Changpeng Zhao, the founder of Binance.
What is Sign Protocol?
Sign Protocol is a cutting-edge omni-chain attestation protocol that enables users to verify and attest information on the blockchain. It focuses on creating a more transparent, secure, and efficient token distribution infrastructure for both humans and AI agents. Since its founding in 2021, Sign Protocol has emerged as a leader in the token distribution sector, trusted by over 200 projects, including Starknet, Movement, and ZetaChain.
How Does Sign Protocol Work?
Sign Protocol offers a scalable solution for verifying claims and assertions on the blockchain. Its key features include omni-chain attestation support, off-chain and on-chain modes for storing attestations, verifiable consent through cryptographic proofs, and privacy features that allow passwordless private attestations.
Future Development of Sign Protocol
With fresh funding, Sign Protocol plans to expand its partnerships with centralized exchanges and governments, integrate AI-driven applications, and launch its native token. These steps will help bolster Sign's ecosystem and continue driving blockchain adoption through secure token distribution and credential verification.
By simplifying the token distribution process, Sign Protocol aims to onboard users from traditional internet platforms into the blockchain-based Web3 world, which is crucial for the mass adoption of blockchain technology.
