Sign Protocol: Unifying “Who You Are” and “What You Own” into a Single On-Chain Standard

As the digital tide accelerates, the way the world operates is being redefined almost daily. The boundaries between identity, data, and assets are increasingly blurred.

As the digital tide accelerates, the way the world operates is being redefined almost daily. The boundaries between identity, data, and assets are increasingly blurred. Web3 is giving back the right to define “trust” in the hands of individuals, away from centralized institutions.

But this transformation brings challenges: replicating real-world identity verification, asset distribution, and regulatory frameworks on chain is far from simple. Fragmented data, lack of standardized protocols, and high compliance costs have become a “glass ceiling” impeding global coordination.

To shatter this ceiling, we need a universally accepted trust infrastructure—one that can be embraced by sovereign nations, multinational enterprises, and Web3-native communities alike. This is exactly what Sign Protocol is building.

In short, Sign aims to unify “who you are” and “what you own” into a single on chain standard, creating a frictionless, secure, and scalable infrastructure for individuals, enterprises, and governments to operate at full speed on the same digital highway.

Project Overview: What Problems Is Sign Addressing?

Project Summary

Sign is actively participating in multiple national-level digital infrastructure projects, with deployments in the UAE, Thailand, and Sierra Leone. Its expansion plans encompass over 20 countries and regions, including emerging digital governance hubs like Barbados and Singapore.

In terms of product metrics, the number of credential templates in Sign Protocol has grown exponentially. The TokenTable platform has distributed over $4 billion, covering more than 40 million on chain wallet addresses and serving over 200 projects, including major ecosystems like Starknet, ZetaChain and Notcoin.

Capital markets are gradually recognizing its value. Sequoia Capital has taken part in the investment across the region, and YZi Labs led subsequent funding rounds. Sign has achieved $15 million in annual revenue, making it one of the few identity verfication and asset distribution infrastructure projects with a viable income model, showcasing strong market competitiveness and growth potential.

Project Vision

Sign introduces the concept of a “supranational database”, aiming to create a globally verifiable and auditable information structure through blockchain technology. Sign seeks to provide a programmable foundation for digital identity verification, token logic standardization, and trustworthy data transmission, promoting the integration of on chain governance, economy, and identity to become the underlying engine for global digital collaboration.

Core Positioning

Sign’s core architecture focuses on two key modules: identity verification infrastructure and token distribution infrastructure. Building on this, Sign is developing a standardized, programmable, and cross-chain deployable trust layer protocol. This protocol meets the fundamental needs of Web3 while offering a highly compatible identity and distribution system with the real world, providing a reliable foundation for global trust and value transfer.

Technical Architecture: The Foundations of Sign

Leveraging Sign Protocol and its suite of products：TokenTable, SignPass, and EthSign, Sign bridges the three onchain on chain engines of identity, services, and assets, spearheading the construction of next-generation digital-society infrastructure.

Sign Protocol: A Omni-Chain Attestation Protocol

Sign Protocol boasts exceptional scalability and flexible deployment capabilities. It supports cross-chain deployments and can be locally implemented on sovereign chains to meet regulatory compliance requirements. Utilizing Arweave ensures off-chain data redundancy, enhancing data security and longevity. The indexing layer, managed by SignScan, offers standardized querying and verification of on chain credentials, significantly improving operational convenience and efficiency.

The protocol supports local contract interactions and remote deployment architectures, integrating various identity sources from both Web2 and Web3. By employing asymmetric encryption and zero-knowledge proof mechanisms, Sign provides robust identity verification while ensuring complete user privacy protection, allowing users to enjoy convenient services without concerns about personal information leakage.

TokenTable: The Digital Asset Distribution Engine

TokenTable stands as one of the most comprehensive digital asset distribution engine. The Unlocker module offers a fully on chain, trustworthy token unlocking solution, suitable for complex unlocking logic like linear releases and event triggers. The Merkle Distributor employs a hybrid design, saving gas costs while maintaining flexible distribution logic. The Signature Distributor focuses on centralized, high-efficiency distribution scenarios, catering to activities requiring social interaction and complex behavioral incentives.

SignPass: On Chain Identity System

SignPass provides a highly configurable on chain identity system for governments and organizations, effectively supporting applications in digital governance, resource allocation, and user authentication. With SignPass, user identities can be easily reused across different protocols and platforms, serving as authoritative credentials for participating in on chain governance and various activities, significantly enhancing user convenience and identity recognition in the

The Role of the SIGN Token in the Ecosystem

The SIGN token, adhering to the ERC-20 standard, serves as the core macroeconomic incentive mechanism and functional token of the Sign protocol. It has a current maximum supply of 10 billion tokens, with an initial circulation ratio of 12%, and roughly 8.5% of the tokens are available for trading, ensuring market stability in the early stages while providing ample space for long-term governance incentives and a solid foundation for ecosystem development
