Sign is a blockchain infrastructure project dedicated to establishing verifiable trust across decentralized networks. Founded in 2021, Sign has developed two core products: Sign Protocol, an omni-chain attestation framework, and TokenTable, a smart contract-based platform for token distribution. Together, these tools aim to revolutionize credential verification and token management in the Web3 ecosystem.

Sign Protocol: Omni-Chain Attestation Framework

Sign Protocol enables users to create and verify attestations—structured, verifiable claims—across multiple blockchain networks, including Ethereum, Solana, TON, and others. By utilizing schemas to standardize data formats and supporting both on-chain and off-chain storage solutions like Arweave and IPFS, Sign Protocol offers a flexible and secure method for information verification.

Key features of Sign Protocol include:

• Cross-Chain Compatibility: Facilitates attestations across various blockchain platforms.
• Schema Registry: Standardizes data structures for consistent attestation formats.
• Decentralized Storage Integration: Supports Arweave and IPFS for off-chain data storage.
• SignScan Explorer: Provides tools for querying and managing attestations.

These capabilities make Sign Protocol suitable for applications in digital identity verification, supply chain management, and decentralized governance systems.

TokenTable: Smart Contract-Based Token Distribution

TokenTable is designed to streamline token distribution processes, including airdrops, vesting schedules, and unlocks. By leveraging smart contracts and on-chain verification, TokenTable has facilitated the distribution of over $4 billion in tokens to more than 40 million wallets as of 2024.

Features of TokenTable include:

• Automated Distribution: Manages complex token release schedules with precision.
• Identity Verification: Ensures tokens are distributed to verified recipients.
• Scalability: Handles large-scale distributions efficiently and securely.

These functionalities make TokenTable a valuable tool for projects seeking to manage token economics effectively.

SIGN Token: Utility and Governance

The SIGN token serves as the native utility and governance token within the Sign ecosystem. It facilitates various operations, including the creation of attestations and participation in protocol governance. The tokenomics of SIGN are structured to support the ecosystem's growth and sustainability.

Community and Ecosystem

Sign has cultivated a global community known as the “Orange Dynasty,” uniting developers and users under a shared vision of trust and transparency in decentralized systems. The project has secured over $32 million in funding from prominent investors, including Sequoia Capital and YZi Labs.

Additional products in the Sign ecosystem include:

• EthSign: An on-chain e-signature application.
• SignPass: A system for on-chain identity registration and verification.

Conclusion

Sign is at the forefront of developing infrastructure that brings verifiable trust to decentralized networks. Through its innovative products, Sign Protocol and TokenTable, the project addresses critical needs in credential verification and token distribution. As blockchain technology continues to evolve, Sign's contributions are poised to play a significant role in shaping a more trustworthy and efficient digital future.
