Deep Dive
1. Verifiable records across blockchains
Sign Protocol is an attestation system: it lets an issuer make a digitally verifiable claim and lets others check it. Sign describes the protocol as omni chain, meaning it is designed to work across multiple blockchains. This could support uses such as verifying credentials without relying solely on one centralized database. (Sign Protocol)
2. Token distributions and SIGN
TokenTable is Sign’s smart contract based platform for organizing token distributions, including airdrops, vesting schedules, and unlocks. SIGN is the project’s associated cryptocurrency token; the available project description identifies Sign’s products but does not specify the token’s exact functions in detail. (CoinMarketCap)
Conclusion
Sign combines tools for checking digital claims with software for managing token distributions; SIGN is its ecosystem token. How widely will developers use Sign Protocol to verify information across different blockchains?
