What is Sign?
Sign (Sign Protocol) is an omnichain attestation protocol that allows users to flexibly verify and validate information across multiple blockchains.
In both the real world and the internet, users constantly encounter countless claims and confirmations from various entities.
Instead of relying on traditional assumptions about honesty or the authority of specific organizations, Sign Protocol creates a system where all claims can be verified in a decentralized, transparent, and secure manner.
Sign aims to build a future where information is highly accurate, minimizing reliance on trust. By integrating blockchain, modern cryptography, and an expanding ecosystem, Sign Protocol is poised to bring significant improvements across finance, governance, and data security.
The project has raised over $28 million from prominent investors such as Sequoia Capital, HashKey Capital, YZi Labs, Circle, Animoca Brands, and Shima Capital. The latest funding round of $16 million was completed on January 28.

Core features and technology of Sign
Sign is not a standalone blockchain but a protocol that operates across multiple blockchain networks. Its highly flexible infrastructure allows deployment on any blockchain environment without being restricted to a specific ecosystem.
Sign leverages cutting-edge technologies such as decentralized blockchain systems, secure data storage solutions, zero-knowledge cryptography, and digital signatures.
This robust foundation ensures that all attestations are reliable, transparent, and publicly verifiable without exposing sensitive information.
Sign supports Ethereum, EVM-compatible blockchains, TON, and Solana. Its scalability enables seamless integration into various ecosystems, enhancing the protocol’s applicability in real-world solutions.
One of Sign’s standout features is the Schema Registry, which facilitates standardization and expansion of attestations on blockchain. This system allows individuals and enterprises to efficiently build applications that utilize attestations.
Real-world applications of Sign
Sign can be applied in various fields, including:
Identity verification & reputation systems: Helps build decentralized reputation networks for verifying personal or organizational credentials.
Loyalty & rewards programs: Supports transparent and verifiable customer loyalty points and reward distribution.
Trust & referral networks: Establishes platforms for verifying relationships and referrals between individuals or businesses.
Governance enhancement: Integrates into decentralized governance (DAO) systems to improve transparency and efficiency in voting and decision-making.
Sign is actively developing integrations with popular applications and user experiences. The project has announced plans to release further details on upcoming integrations soon.

Binance HODLER Program
Unlike other earning methods that require ongoing actions, HODLer Airdrops reward users retroactively, offering a simple way to earn additional tokens. By subscribing BNB to Simple Earn products and/or On-Chain Yields, users can automatically qualify for token rewards.
Participating in the HODLer Airdrops does not affect users’ standard benefits for holding BNB, such as eligibility for Binance’s Launchpool and Megadrop events. Instead, it provides additional rewards and benefits on top of existing perks, ensuring a steady stream of passive income for BNB holders.
