Reputation System Solutions

As a reputation scoring system, Solana ID gave each user a single SOLID score and put money behind it. Users could stake the SOLID token to underwrite their own score, which exposed anyone trying to game the system to a slashing-style penalty. When a verifier paid to query user data, half of the protocol revenue went to the users who had agreed to share it. The design was aimed at projects that wanted to target rewards by reputation, and at users willing to share data for a cut. It did not last: Solana ID closed in September 2026, with the team saying its two-sided market never drew enough campaigns or enough scored users to sustain itself. The team burned its treasury allocation, 73.78% of SOLID supply, and locked the liquidity pools, so the token still trades with no product behind it.

.blink implements a sophisticated reputation system on Solana through its unique combination of verified usernames, social connections, and on-chain activity tracking. The platform allows users to build and maintain their reputation through verifiable interactions and connections within the Solana ecosystem. By mapping social relationships and activities on-chain, .blink creates a transparent and immutable record of user reputation that can be leveraged across different applications.The platform's reputation scoring capabilities are enhanced by its social graph features, which allow users to establish verified connections with other .blink identities. These connections, combined with on-chain activity metrics, contribute to a user's overall reputation within the ecosystem. The system's integration with various Solana dApps means that reputation scores can be utilized for different purposes, from access control to participation in token-gated communities, creating a robust and meaningful reputation framework.

Daemon Protocol maintains a persistent on-chain reputation registry for AI agents operating on Solana, recording behavioral history and trust scores that compound over time. Agents that execute reliably, fulfill their stated functions, and avoid slashing events accumulate positive reputation that makes them more credible counterparties in protocol interactions requiring automated execution. The registry design ensures that reputation is non-transferable and tied to the agent's on-chain identity, preventing reputation laundering through address changes. For protocols evaluating which AI agents to authorize for sensitive functions — oracle updates, treasury management, automated liquidity provision — the reputation registry provides a reference that goes beyond static whitelists. Historical performance data, bonding status, and Proof of Agency verification records combine into a composite trust signal that protocol governance participants can evaluate before granting elevated permissions to any autonomous system.
