Technical Architecture
For the engineers in the room. Every component purpose-built from scratch in Rust — not forked, not wrapped, not abstracted away.
Consensus
Same protocol family powering Sui (Mysten Labs). Implemented from scratch in Rust. Not forked. Narwhal separates data dissemination from consensus ordering, enabling massive throughput without sacrificing safety.
Bullshark provides deterministic ordering with optimal latency. The DAG structure ensures every validator sees the same transaction history, achieving Byzantine fault tolerance with 80 validators across 8 data centers.
An attacker must simultaneously compromise 27 validators in 3 entire data centers to affect a single settlement. Every transaction is certified by a cryptographic supermajority before it settles.
Tolerates up to 26 malicious validators out of 80
Verified, finalized, irreversible settlement
Geographically distributed for resilience
Every batch proven available on supermajority before ordering
Data Availability
Every transaction batch is proven available on a supermajority of validators before consensus orders it. This is not an assumption — it's a cryptographic guarantee.
Validators attest to data availability before the ordering protocol considers a batch. This eliminates the "data withholding" attack vector that plagues other consensus systems. If data isn't available, it doesn't get ordered. Period.
Batch Creation
Validator collects transactions into a batch and creates a cryptographic digest.
Dissemination
Batch is sent to all other validators for storage and verification.
Attestation
Each receiving validator signs an availability certificate confirming storage.
Certificate
Once 2f+1 validators attest, a Certificate of Availability is formed — consensus can order it.
Execution
Transactions are partitioned by sender address and executed in parallel across all available CPU cores. No global lock. No sequential bottleneck. Linear scaling with hardware.
This is why QSecure achieves 1,000,000+ TPS — not through layer-2 tricks or off-chain gimmicks, but through fundamental architectural decisions that make parallelism native to the protocol.

State Management
Persistent storage with write-ahead logging, crash recovery, and Merkle proofs for every account. Every validator independently computes and verifies the same cryptographic state root.
State consistency isn't assumed — it's mathematically verified. Identical cryptographic root across all validators. Not eventual consistency. Not best-effort. Proven identical.
Write-Ahead Logging
Every state mutation logged before execution for crash recovery
Merkle Proofs
Cryptographic proof for every account balance and state transition
Crash Recovery
Full state reconstruction from WAL on any validator restart
Memory Footprint
78-120 MB per validator — runs on commodity hardware
Cryptography Stack
Every cryptographic primitive chosen for a specific purpose. No generic "crypto library" — each algorithm selected for its security properties and performance characteristics.

Codebase
An auditor reads the entire protocol in a weekend. Not hundreds of thousands of lines inherited from a fork. Every line written with purpose. Every function tested.
10 crates. 161 tests. Zero failures. The entire settlement protocol is open source — read every line, run every test, reproduce every benchmark.
