Exploring a New Era of Trust in Blockchain: Sign Builds a Global Verification System

In the wave of decentralization, trust remains the key to the integration of the real world and Blockchain. Sign, as an emerging on-chain verification system, is centered around the Sign Protocol and is committed to enabling global verification of identity, protocols, credit, and other information. This article delves into Sign's vision, technological breakthroughs, and future plans, aiming to reveal how Blockchain is reshaping trust mechanisms and driving public services on-chain.

The co-founder of Sign, Yan Xin, introduced the company's development history. Founded in 2021, Sign has developed the global verification system Sign Protocol, allowing information such as identity, protocol, and credit to be verified worldwide, similar to Blockchain transactions. The company achieved $15 million in revenue in 2024. Sign's goal is to migrate important scenarios and public services to Blockchain, utilizing Blockchain as an efficient, accurate, and auditable global ledger.

Regarding the concept of "trust" in a "trustless network", Yan Xin pointed out that although Blockchain is essentially a trustless network, decision-making in the real world still relies on trust. Sign is dedicated to bringing real-world trust mechanisms onto the chain by deploying smart contracts across multiple blockchains, providing on-chain verification systems for various organizations.

Sign Protocol is likened to "on-chain notaries" and plays a role similar to that of notary institutions in real life within the blockchain world. For the average user, the core value of Sign Protocol lies in ensuring the transparency and secure verification of identities and information through blockchain technology, making on-chain identities not only represent a wallet address but also represent a "person" with complete social credit and background.

In terms of privacy protection, Sign Protocol extensively uses zero-knowledge proof technology but has not yet involved fully homomorphic encryption. Their design philosophy is to only conduct verification without the need to compare or put sensitive information on the blockchain, ensuring compliance with data protection regulations.

Regarding the EthSign product, Yan Xin emphasized that its core advantages lie in free verification globally, as well as features such as no subscription, no spam, and permanent encrypted storage of documents. EthSign is based on the U.S. Electronic Signatures in Global and National Commerce Act and has been recognized by most international standards.

SignPass, as a new authentication system for Sign, has started to provide support for certain countries and regions. In the face of different regulatory requirements globally, SignPass adopts a dual-track strategy of technological compliance and policy compliance, ensuring compliance in different regions through privacy-enhancing technologies and modular configurations.

Looking to the future, Sign plans to launch a comprehensive application that integrates functions such as identity verification and wallet management. The company's long-term goal is to create the most compliant and cutting-edge Web3 digital identity paradigm globally, achieving a vision of trust without borders and portable identities.

The development roadmap of Sign focuses on exploring "on-chain government efficiency" and is committed to promoting blockchain applications at the international level, migrating public services to the blockchain as a public infrastructure. Through these efforts, Sign is making a positive contribution to building a more efficient and transparent global trust system.
