Sentinel is an advisory on-chain governance risk oracle designed for Solana DAOs.
It analyzes participation patterns in governance proposals and emits deterministic on-chain risk signals before execution — without interfering with DAO autonomy.
Sentinel acts as a coordination awareness layer, helping DAOs detect governance fragility while preserving decentralization.
Most DAO governance systems evaluate proposals only at execution time:
✔ quorum reached
✔ vote passed
But they do not evaluate:
❌ rushed participation
❌ late vote dominance
❌ weak consensus formation
This can result in coordination failures — where technically valid proposals lack meaningful legitimacy.
Sentinel introduces a neutral, on-chain advisory layer to detect these patterns early — without enforcing outcomes.
Proposal → Participation Tracking → Risk Computation → Advisory Signal
Sentinel maintains three deterministic accounts per proposal using Program Derived Addresses (PDAs).
Stores proposal metadata.
Seed:
["proposal", proposal_pubkey]
Fields:
- proposal_pubkey
- voting_start_ts
- voting_end_ts
Tracks participation behavior.
Seed:
["metrics", proposal_pubkey]
Fields:
- total_votes
- late_votes
- late_vote_ratio_bps
Stores advisory output.
Seed:
["risk", proposal_pubkey]
Fields:
- risk_level
- computed_at
Sentinel uses a deterministic late-vote concentration model.
| Late Vote Ratio | Risk Level |
|---|---|
| ≤ 30% | LOW |
| > 30% | MEDIUM |
| > 60% | HIGH |
The resulting risk signal is stored on-chain as an advisory output.
Sentinel does not block execution — it only surfaces governance coordination risk.
