## Technical Architecture

TBURN L2 is built with 18 mathematical algorithm engines:
1. EWMA (α=0.3) — Exponentially Weighted Moving Average for TPS smoothing
2. Kalman Filter — Real-time TPS projection with noise reduction
3. GARCH(1,1) — Volatility estimation for network load prediction
4. Welford Online Algorithm — P50/P95/P99 block-time statistics
5. rANS Compression — 93% ZK batch compression ratio
6. HKDF-SHA256 — Session key derivation for ILB security
7. HMAC-SHA256 — 12-layer message authentication
8. Welford Variance — Standard deviation tracking for anomaly detection
9. LCG (Linear Congruential Generator) — Deterministic address generation
10. Box-Muller Transform — Gas usage normal distribution modeling
11. Pareto Distribution — Transaction value distribution modeling
12. EWMA Latency Tracker — P95 SLA monitoring
13. Circuit Breaker FSM — 3-state (CLOSED/OPEN/HALF_OPEN) reliability
14. Sliding Window Rate Limiter — Adaptive throughput control
15. Monotonic Sequence Validator — Replay attack prevention
16. CQS (Connection Quality Score) — 4-factor network health metric
17. BFT Quorum Voting — Byzantine fault-tolerant consensus
18. Merkle State Root — ZK state commitment per block
