The Solid team is building a decentralized identity infrastructure on Solana, leveraging the Solana Attestation Service (SAS) to enable verifiable, composable identity primitives. They empower users to mint a unique on-chain identity ("Priority Pass") that serves as a foundation for collecting attestations—such as KYC, reputation, and social credentials—which are issued by trusted third parties via SAS. These attestations are stored on-chain in a privacy-preserving, modular format, enabling users to selectively disclose and monetize their data across Web3 applications. Solid’s approach promotes user sovereignty, interoperable identity, and trustless data exchange in the Solana ecosystem.
Use Cases
1. User Identity Creation and Verification
- Minting a Priority Pass: Users initiate their identity on Solid by minting a "Priority Pass," which serves as their unique digital identifier within the Solana ecosystem. This pass is linked to their Solana wallet and acts as a personal identity passport across various decentralized applications (dApps) .
- Attestation of Credentials: Solid leverages Solana's attestation services to verify user credentials. These attestations can include KYC verifications, social media account linkages, or proof of participation in specific events. The attestations are stored on-chain, ensuring user ownership and immutability.
2. Data Sharing and Monetization
- Controlled Data Sharing: Users have the autonomy to decide which pieces of their verified data they wish to share with third-party services. This selective sharing is facilitated through the attestation framework, allowing users to maintain privacy while engaging with various platforms.
- Earning through Data Sharing: When users choose to share their data, they can earn rewards in the form of tokens. This incentivizes users to participate in the ecosystem and provides a mechanism for monetizing personal data.
3. Reputation Building and Staking
- Reputation Scores: As users accumulate attestations and engage with the ecosystem, they build a reputation score. This score can influence their access to certain services or benefits within the platform.
Staking for Enhanced Benefits: Users can stake their tokens to enhance their reputation scores further. A higher reputation can unlock additional perks or access to exclusive services, creating a gamified aspect to user engagement .
