Solana Verification Service: Reshaping On-chain Identification

Solana verification service ( SAS ) is an open, permissionless protocol designed to achieve on-chain secure and verifiable credentials while protecting users' sensitive personal data. This service allows trusted third parties to create proofs regarding user identification or qualifications, and these verifications are stored in the user's wallet.

SAS can be used for the verification of various information, including KYC status, geographical eligibility, qualified investor identification, age verification, and association with real-world organizations or activities. The verification itself does not disclose sensitive information, but rather serves as an encrypted proof indicating that the claim has been verified by a trusted party. This method achieves seamless secure access to services while protecting privacy.

Solana Identification Group: Driving the Future of On-Chain Identification

The SAS plan is the first achievement of the Solana identification group, which is a collaborative project composed of ecosystem participants. Participants include the Solana Foundation, Civic, Solana.ID, Trusta Labs, and Solid. These organizations are jointly laying the foundation for a standardized and composable identification layer on Solana.

How SAS Works

SAS operates through a third-party model and a dedicated on-chain program:

1. Issuer: A trusted third party creates verification for users.
2. SAS program: responsible for issuing, verifying, and managing the on-chain identification.
3. Holder: Users receive identification and store it in a digital wallet.
4. Verifier: Requests the verification of certain attributes from DApp, protocol, or smart contract.

Since the system is non-custodial, composable, and interoperable, developers can flexibly combine verification without the need to design the verification system from scratch.

Key Features of SAS

• Portable Certificate
• Default Privacy Protection
• Composable and interoperable
• Instant verifiability
• Open Infrastructure

Core Use Cases of SAS

SAS supports a wide range of applications in Web3, including:

• KYC identification
• Region-based access control
• Witch Attack Resistance
• Investor Qualification Verification
• DAO Reputation System
• DePIN and location proof

Ecosystem Adoption

Multiple leading projects have integrated or announced plans to support the SAS protocol, including Civic, Solana.ID, Solid, Trusta Labs, RNS.ID, Wecan, Polyflow, Range, Sumsub, and Honeycomb protocols.

Comparison between SAS and World Network

SAS and World Network ( World ID ) both aim to bring trust and privacy to Web3, but they take different approaches. SAS focuses on regulatory compliance and privacy protection of real-world credentials, while World ID emphasizes human identification and utilizes biometric technology.

World Network has faced scrutiny or been banned in multiple countries due to privacy and regulatory issues, including Spain, Hong Kong, Germany, Kenya, and Indonesia. In contrast, SAS offers a more privacy-friendly solution by leveraging cryptographic verification from trusted issuers.

The Future of Solana Programmable Identification

Solana verification service lays the foundation for building a safer and smarter Web3. It provides users with control, developers with speed and trust, and regulatory bodies and institutions with compliance assurance.

With the growing demand for identity-aware applications in DeFi, gaming, and real-world asset platforms, SAS has made Solana a pioneer in secure and scalable on-chain identity infrastructure. Although SAS is still in its early stages and its long-term viability and scalability remain to be further verified, its potential within the Solana ecosystem is immense.
