Consensus Mechanism
Block production and finality
Selendra uses Aura for block production and AlephBFT for finality.
Aura (Block Production)
- Authority-based round-robin
- 1-second blocks
- Validators selected by stake weight
- Deterministic and predictable
AlephBFT (Finality)
- Byzantine Fault Tolerant
- 2-3 second finality
- Finalized blocks never revert
- Used by AlephZero and other production chains
Validator Selection
- Minimum stake requirement (25K SEL)
- Current: 4 validators
- Roadmap: 20 by 2026, 50+ by 2027
- Rotated every era (24 hours)
Security
- Requires 2/3 honest stake
- No forks after finality
- Higher threshold than Bitcoin's 51%
Penalties
- Equivocation → slashing
- Offline → no rewards
- Nominators share validator's penalties
Performance
- 3000+ tx/s minimum
- 2-second average finality
- Suitable for retail payments
Production Use
Selendra: Independent L1 chain (not a parachain), full sovereignty over consensus.
