# Obsero Security Model

Obsero ensures resilience and integrity through multiple layers of protection.

## Threats Addressed

- Proof forgery: ECDSA signature validation
- Data tampering: Immutable hashing
- Spam attacks: Possible stake or fee mechanism
- Replay attacks: Timestamp uniqueness

## Trust Model

- Each observation is individually signed.
- Trust shifts from the observer to cryptographic proofs.
- Full auditability through IPFS and blockchain.
