Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Cryptographic Issues: Poor randomness in signature generation poses an existential threat of private key exposure. The project migrated to deterministic RFC 6979 signatures to mitigate this risk.
Cryptographic Issue: Taproot signatures (Schnorr) are highly vulnerable to weak RNG conditions. Forcing nonce derivation to depend on both random bytes and the transaction hash ensures cryptographic resilience.
Denial of Service: The peer database and network subsystem are vulnerable to address flooding, which can exhaust disk, memory, and CPU resources unless strict bounds on peer accumulation and database growth are enforced.
