QNet implements a 5-level confirmation system for exchanges, bridges, and users:
Pending (0s) → In mempool, not yet in block
↓
InBlock (1-2s) → 1-4 confirmations, safe for small amounts
↓
QuickConfirmed (5-10s) → 5-29 confirmations, safe for medium amounts
↓
NearFinal (30s) → 30-89 confirmations, safe for large amounts
↓
FullyFinalized (90s) → In macroblock, safe for any amount
Confirmations → Safety Percentage:
0 blocks → 0.0% (pending)
1 block → 92.0% (in microblock)
5 blocks → 100.0% (quick confirmed)
10 blocks → 99.3% (highly safe)
30 blocks → 99.9% (near final)
90+ blocks → 100.0% (fully finalized)Safety ≥99.99% → safe_for_any_amount
Safety ≥99.9% → safe_for_amounts_under_10000000_qnc (10M QNC = 0.25% supply)
Safety ≥99.0% → safe_for_amounts_under_1000000_qnc (1M QNC = 0.025% supply)
Safety ≥95.0% → safe_for_amounts_under_100000_qnc (100K QNC)
Safety ≥90.0% → safe_for_amounts_under_10000_qnc (10K QNC)

}Traditional Approach:
- All withdrawals wait 90 seconds for full finality
- Poor user experience
- Slow cross-chain operations
QNet Fast Finality:
- Small amounts (10K QNC): 1-2 seconds (92% safe)
- Medium amounts (100K QNC): 5 seconds (100% safe)
- Large amounts (1M QNC): 10 seconds (99.3% safe)
- Very large amounts (10M QNC): 30 seconds (99.9% safe)
- Any amount: 90 seconds (100% finalized)
Performance Impact:
- Zero storage overhead (calculated on-the-fly)
- <1 microsecond computation time
- Backward compatible (optional fields)
- Scales to millions of requests/second
QNet implements a simplified and reliable fork resolution mechanism:
Block Received → Hash Comparison → Fork Detected → Async Resolution
↓ ↓ ↓ ↓
Deserialize SHA3-256 check FORK_DETECTED:H:P Background task
vs local block (non-blocking)
CASE 1: Network ahead (network_height > local_height)
└── Rollback to fork_point → sync_blocks() from network
CASE 2: Same height (network_height == local_height)
└── Count high-rep validators (≥70%) → If ≥3: rollback + resync
└── If <3 validators: keep chain, wait for more connections
CASE 3: We're ahead (local_height > network_height)
└── Keep our chain (we have longer chain)
Key Design Decisions:
- Simple over complex: Resync from network majority instead of complex weight calculations
- Trust high-reputation validators: Minimum 3 validators with ≥70% consensus_score required
- Macroblock finality: Ultimate fork resolution via macroblock consensus (every 90 blocks, 67%+ required)
- No complex weight calculations: Removed in favor of simpler, more reliable approach
- Race Condition Prevention: Single concurrent reorg with RwLock flag
- DoS Protection: Maximum 1 fork attempt per 60 seconds (rate limiting)
- Deep Reorg Protection: Maximum 100 blocks sync per request
- Validator Threshold: Minimum 3 high-reputation peers required for resync decision
- Macroblock Finality: Forks without 67% consensus cannot create macroblocks
- Fork Detection: <1ms (SHA3-256 hash comparison)
- Resolution Decision: <5ms (peer count + reputation check)
- Reorg Execution: 50-200ms (background processing)
- Memory Overhead: <5MB (no complex tracking needed)
- Network Impact: Zero blocking (async execution)
QNet implements sophisticated synchronization for handling network latency:
Block #N+5 arrives → Missing #N+1,N+2,N+3,N+4 → Buffer #N+5 → Request Missing
↓ ↓ ↓ ↓
Validate Check previous_hash Store with pseudo- Active P2P
Structure in pending_blocks infinite retries sync_blocks()
Buffer Management (v2.19.20):
- HashMap storage: O(1) lookup by block height
- Pseudo-infinite retries - blocks NEVER discarded
- Adaptive buffer size: Full/Super 500 blocks (~50MB), Light 100 blocks (~10MB)
- Exponential backoff: 10s (retries 0-9) → 30s → 60s → 120s → 240s → 300s max
- Timestamp tracking for age-based re-request (not eviction)
Missing Block Detected → Rate Limit Check → Request via P2P → Track & Backoff
↓ ↓ ↓ ↓
MISSING_PREVIOUS:H Exponential sync_blocks(H, H) Update timestamp
backoff Non-blocking Max 10 concurrent
Protection Mechanisms:
- Request Cooldown: 10s (aggressive) → 30s-300s (exponential backoff)
- Maximum Attempts: Pseudo-infinite (never give up on blocks)
- Concurrent Limit: Maximum 10 simultaneous requests
- Background Re-request: Every 30 seconds with exponential backoff
When dependency arrives, process up to 10 consecutive buffered blocks:
Block #N arrives → Check pending_blocks[N+1..N+10] → Re-queue all found → Process in parallel
↓ ↓ ↓ ↓
Save to DB Find consecutive blocks tokio::spawn tasks Update height
Performance Benefits:
- Fast Forward: Process multiple blocks simultaneously
- Network Efficiency: Batch processing reduces overhead
- Scalability: O(1) buffer lookup, O(n) re-queue where n≤10
Previously, each node created its own Genesis block with different signatures, causing split-brain scenario.
Genesis Creation:
1. ONLY node_001 creates Genesis (bootstrap mode)
2. Quantum-resistant CRYSTALS-Dilithium signature
3. All nodes verify SAME Genesis hash
4. Production mode: Never create Genesis, only sync
Genesis Block Signature:
SHA3-256(block_content + "qnet_genesis_seed_2025")
Benefits:
- Network Consistency: Identical Genesis across all nodes
- No Split-Brain: Single source of truth
- Fast Verification: SHA3-256 hash comparison
- Scalability Ready: Production nodes only sync, never create
QNet integrates Verifiable Time Sequence for verifiable time ordering:
VTS Chain: H₀ → H₁ → H₂ → ... → Hₙ
↓ ↓ ↓ ↓
Hybrid SHA3-512/Blake3 (25%/75%)
500K hashes/second
Properties:
- Sequential Hash Chain: 25% SHA3-512 creates sequential bottleneck for ordering
- Cryptographic Timestamps: Each hash proves ordering and time progression
- Fork Prevention: Creating alternative history requires recomputing entire VTS chain
- Performance Balance: Blake3 for speed, SHA3-512 intervals for sequential ordering
- Sub-Second Precision: Accurate time measurement across distributed network
MicroBlock {
height: u64,
timestamp: u64, // Unix timestamp
poh_hash: [u8; 64], // VTS chain state at block creation
poh_count: u64, // Number of VTS hashes since last block
previous_hash: [u8; 32], // Link to previous block
...
}Use Cases:
- Time Synchronization: Nodes agree on block ordering without central clock
- Fork Detection: Competing chains must have valid VTS history
- Transaction Ordering: Cryptographic proof of event sequence
- Network Latency Compensation: VTS continues during network partitions

struct HybridSignature {
certificate: HybridCertificate {
node_id: String,
ed25519_public_key: [u8; 32], // RAW bytes

},
ephemeral_public_key: [u8; 32], // NEW Ed25519 key RAW
message_signature: [u8; 64], // Ed25519 signs message RAW
dilithium_key_signature: Vec<u8>, // RAW bytes (~2500 bytes)

}
// Signing Process (v2.23):

Unique feature: QNet is the first blockchain to implement NIST/Cisco encapsulated keys for quantum-resistant hybrid signatures with per-message ephemeral key rotation
QNet implements a two-tier block structure:
-
Microblocks (every second):
- Contain user transactions
- Single producer signature
- Fast processing
- Size: ~200-500 bytes
- Producer rotation: Every 30 blocks (30 seconds)
- Selection method: SHA3-256 hash with entropy from previous round
- Rewards: +1 reputation per block produced
-
Macroblocks (every 90 seconds):
- Aggregate 90 microblocks
- Byzantine consensus with up to 1000 validators
- Active listener on all Full/Super nodes (1-second polling)
- Consensus window: blocks 61-90 (30-block early start)
- State finalization
- Size: ~50-100 KB
- Consensus leader: +10 reputation
- Participants: +5 reputation each
Commit-Reveal Byzantine Fault Tolerance (CR-BFT):
Commit Phase:
- All validators send hash of their vote
- Sign commit with digital signature
- Wait for commits from 2f+1 validators (where f is number of malicious)
Reveal Phase:
- Validators reveal their actual votes
- Verify correspondence to previously sent hash
- Final consensus is reached
Security: System withstands up to 33% malicious nodes
Producer rotation every 30 blocks with entropy:
fn select_producer(height: u64, candidates: Vec<Node>, storage: &Storage) -> Node {
let round = height / 30;
let round_start = round * 30;
// Use previous round's last block hash as entropy
let entropy_block = if round_start > 0 {
storage.get_block_hash(round_start - 1)
} else {
genesis_hash() // First round uses genesis
};
let mut hasher = Sha3_256::new();
hasher.update(&round.to_le_bytes());
hasher.update(&entropy_block);
// Filter by reputation >= 70%
let eligible: Vec<Node> = candidates
.filter(|n| n.reputation >= 0.70)
.take(1000) // Max 1000 validators
.collect();
let hash = hasher.finalize();
let index = hash % eligible.len();
eligible[index]
}True randomness through entropy ensures unpredictable producer rotation while maintaining consensus across all nodes.
To ensure Byzantine-safe consensus at rotation boundaries, QNet implements adaptive entropy verification:
// At rotation boundaries (blocks 31, 61, 91...):
// 1. Adaptive sample size based on network size
let qualified_producers = p2p.get_qualified_producers_count();
let sample_size = match qualified_producers {
0..=50 => min(peers.len(), 50), // Genesis: 100% coverage
51..=200 => min(peers.len(), 20), // Small: 10%
201..=1000 => min(peers.len(), 50),// Medium: 5%
_ => min(peers.len(), 100), // Large: 10% of active producers
};
// 2. Query sampled peers for their entropy hash
// 3. Dynamic wait with Byzantine threshold (60%)
let byzantine_threshold = (sample_size * 0.6).ceil();
loop {
if matches >= byzantine_threshold { break; } // Fast exit!
if timeout { break; }
sleep(100ms);
}Benefits:
- Scalability: O(log log n) sample growth (5 → 100 for 5 → 1M nodes)
- Speed: 2-20× faster than fixed timeout (200ms-2s vs 4s)
- Byzantine-safe: 60% threshold ensures consensus
- Network-efficient: < 1 KB/s bandwidth, 0.002% CPU overhead

Deterministic Blockchain-Based Reputation (v2.24):
ARCHITECTURE v2.24: Reputation computed from blockchain data + FULL snapshots in macroblocks. All nodes have IDENTICAL reputation state after every macroblock - 100% synchronized. See docs/REPUTATION_SYSTEM.md for full documentation.
/// FULL reputation snapshot stored in every macroblock (v2.24)
pub struct FullReputationSnapshot {
pub reputations: HashMap<String, f64>, // node_id -> reputation (0-100)
pub active_jails: HashMap<String, (u64, u32)>, // node_id -> (end_ts, offense_count)
pub permanent_bans: HashSet<String>, // Permanently banned nodes
pub offense_counts: HashMap<String, u32>, // Progressive jail tracking
pub last_passive_recovery: HashMap<String, u64>, // Recovery timers
pub processed_rotations: HashSet<u64>, // Duplicate protection
}Why Snapshots (not just Computation)?
| Issue | v2.1 (Computed Only) | v2.24 (Snapshots) |
|---|---|---|
| Out-of-order blocks | Reputation drift | Snapshot authoritative |
| Jail persistence | In-memory only | Stored in blockchain |
| Ban persistence | In-memory only | Stored in blockchain |
| Offense counts | In-memory only | Stored in blockchain |
| Node sync | May disagree | 100% identical after macroblock |

├── Prevents long-range attacks
├── Cannot rewrite finalized history

├── Full Nodes: 80% (8+ out of 10 heartbeats in current window)
└── Super Nodes: 90% (9+ out of 10 heartbeats in current window)
Architecture (v2.23):

> **Note (v2.19.10)**: Sharding is for parallel TX processing, NOT storage partitioning. All nodes receive all blocks via P2P.
Real threshold values:
- consensus_score ≥ 70: Full/Super consensus eligibility + ALL node types NEW rewards
- consensus_score < 70: No consensus, no NEW rewards (network access only)
- consensus_score < 10: Complete network ban (can still claim OLD rewards)
NEW Rewards eligibility (unified for ALL node types):
- ALL Nodes (Light/Full/Super): Reputation ≥70 required for network to ping you → NEW rewards
- Light Nodes: Do NOT participate in consensus (viewing only)
- Full/Super Nodes: Participate in consensus (reputation ≥70 required)
Claiming rewards logic:
- NEW rewards: Network pings you ONLY if reputation ≥70 (applies to ALL node types)
- OLD accumulated rewards: NO reputation requirement (only wallet ownership verification)
- Minimum claim: 1 QNC minimum to prevent spam
- Claim interval: 1 hour minimum between claims
- Even banned nodes (<10 rep): Can claim accumulated OLD rewards
Reputation Points (NOT QNC tokens):
| Action | Rep Points | Notes |

Network Score (affects peer prioritization only):
| Event | Penalty | Notes |
|---|---|---|
| Timeout failure | -2.0 | WAN latency (not malicious) |
| Connection failure | -5.0 | Offline/unreachable |
Reputation Gossip Protocol (v2.19.3):
QNet uses exponential O(log n) gossip propagation to synchronize reputation across millions of nodes:
GOSSIP ARCHITECTURE:
├── Complexity: O(log n) vs O(n) broadcast (99.999% bandwidth savings)
├── Interval: Every 5 minutes (periodic sync)
├── Transport: HTTP POST (reliable, NAT-friendly)
├── Fanout: Adaptive 4-32 (same as Shred Protocol block propagation)
├── Signature: SHA3-256 (quantum-safe verification)
└── Scope: Super + Full nodes only (Light nodes excluded)
EXPONENTIAL PROPAGATION (v2.19.19):
├── Initial Send: Node gossips to K closest neighbors by Kademlia distance (K=3)
├── Re-gossip: Each recipient re-gossips to K neighbors (exclude sender)
├── Growth: 1 → 3 → 9 → 27 → 81 → 243 → 729 (7 hops for 729 nodes)
├── Example: 1M nodes = ~20 hops vs 1M HTTP requests (broadcast)
└── Convergence: Weighted average (70% local + 30% remote)
OPTIMIZATIONS (v2.19.20):
├── Fire-and-Forget Broadcast: Shred Protocol doesn't block production (1 block/sec guaranteed)
├── Genesis Startup Wait: 30-second network stabilization before production
├── Emergency Timeout 10s: Allows original producer delivery (was 2s)
├── Pseudo-Infinite Retries: Blocks NEVER discarded
├── Exponential Backoff: 10s (0-9) → 30s → 60s → 120s → 240s → 300s max
├── Adaptive Buffer: Full/Super 500 blocks (~50MB), Light 100 blocks (~10MB)
├── Kademlia K-neighbors: Heartbeats use DHT distance for efficient routing
├── Shred Protocol ALWAYS: Block propagation uses Shred Protocol for ALL network sizes
├── Heartbeat with HYBRID (v2.23): Full quantum protection (Ed25519 + Dilithium per message)
└── Priority channels: Blocks/Consensus use separate channels (implicit priority)
BYZANTINE SAFETY:
├── Signature Verification: Every gossip message verified (SHA3-256)
├── Fork Prevention: All nodes converge to same reputation view
├── Consensus Safety: Producer selection requires same candidate list
└── Graceful Degradation: Continues propagation even with Byzantine nodes
Why Gossip Protocol?
| Network Size | Broadcast O(n) | Gossip O(log n) | Improvement |
|---|---|---|---|
| 1,000 nodes | 1,000 msgs | ~10 hops | 100x |
| 10,000 nodes | 10,000 msgs | ~13 hops | 770x |
| 1,000,000 nodes | 1,000,000 msgs | ~20 hops | 50,000x |
| 10,000,000 nodes | 10,000,000 msgs | ~23 hops | 435,000x |
Convergence Proof:
Let R_i(n) = reputation of node n at peer i
Gossip update:
R_i(n) := 0.7 × R_i(n) + 0.3 × R_j(n) // Weighted average
After k gossip rounds:
R_i(n) → R*(n) // Converges to global consensus value
Byzantine threshold:
consensus_score ≥ 70% for producer selection
If reputation diverges → candidate list diverges → fork risk!
Gossip protocol ensures eventual consistency → no fork risk!
Intelligent Peer Filtering for Block Synchronization:
QNet implements a two-tier blacklist system to optimize sync performance and Byzantine safety:
pub enum BlacklistReason {
// Soft Blacklist (temporary, network issues)
SlowResponse, // 15s → 30s → 60s (escalates)
SyncTimeout, // 30s → 60s → 120s
ConnectionFailure, // 10s → 20s → 40s
// Hard Blacklist (permanent until reputation recovers)
InvalidBlocks, // Permanent (until consensus_score ≥ 70%)
MaliciousBehavior, // Permanent (until consensus_score ≥ 70%)
}Blacklist Behavior:
| Type | Trigger | Duration | Auto-Removal | Purpose |
|---|---|---|---|---|
| Soft | Network timeout/error | 15-120s (escalates) | Time expires | Avoid slow peers temporarily |
| Hard | Invalid blocks, attacks | Permanent | consensus_score ≥ 70% | Isolate malicious nodes |
Escalation Example:
SlowResponse #1 → 15s blacklist
SlowResponse #2 → 30s blacklist (within 5 minutes)
SlowResponse #3 → 60s blacklist (persistent issues)
Recovery: If no issues for 5 minutes → reset counter
Peer Prioritization Algorithm:
get_sync_peers_filtered(max: 20):
1. Filter: Exclude Light nodes (don't store full blocks)
2. Filter: Exclude blacklisted peers
3. Filter: Check consensus_score ≥ 70% (Byzantine-safe)
4. Sort by:
a. Node type: Super > Full
b. network_score (latency): Higher = Better
c. consensus_score (reliability): Higher = Better
5. Sample: Take top 20 peers
6. Return: Prioritized peer list
Benefits:
- ✅ Sync Speed: Top-20 fastest peers selected
- ✅ Byzantine Safety: Malicious peers excluded via consensus_score
- ✅ Resilience: Stuck sync avoided (multiple fallback peers)
- ✅ Scalability: O(n log n) sorting, O(1) blacklist lookup
- ✅ Auto-Recovery: Peers auto-removed from blacklist when reputation recovers
Performance Impact:
| Scenario | Without Blacklist | With Blacklist | Improvement |
|---|---|---|---|
| Sync Speed | 5 blocks/sec (stuck on offline peer) | 50 blocks/sec (top-20 peers) | 10x faster |
| Failed Syncs | 60% (repeated offline attempts) | 5% (blacklist filtered) | 12x reduction |
| Network Overhead | High (retry same peers) | Low (skip blacklisted) | 50% reduction |
Status: ✅ IMPLEMENTED - Private bundle submission with post-quantum signatures
QNet implements dual-layer MEV protection combining natural resistance (reputation-based consensus) with active protection (private bundles):
QNet's reputation-based consensus fundamentally changes MEV economics compared to staking-based systems:
| Aspect | Traditional Staking | QNet Reputation Model |
|---|---|---|
| Producer Incentive | Maximize staking returns | Maintain reputation score |
| MEV Risk | 🔴 High (direct financial benefit) | 🟢 Low (reputational damage) |
| Attack Cost | Lose stake (recoverable) | Lose reputation (permanent, time to rebuild) |
| Producer Window | Long (varies by protocol) | Short (30 blocks = 30 seconds) |
Built-in Resistance Mechanisms:
- No Locked Capital: Producers don't have staked capital to maximize via MEV
- Reputation at Risk: MEV manipulation → permanent reputation damage → consensus exclusion
- Short Production Windows: 30-block rotation limits MEV opportunity
- Deterministic Selection: SHA3-512 entropy-based selection (finality window prevents individual manipulation)
- Byzantine Oversight: Macroblock consensus provides additional verification layer
- Entry Cost Barrier: 1DEV burn + QNC pool make Sybil MEV attacks expensive
Architecture: Flashbots-style private submission compatible with 1-second microblocks
User Transaction Flow:
┌─────────────────────────────────────────────────────────────┐
│ Standard TX Path (Public) │
│ User → Public Mempool → Block Producer → Microblock │
│ │
│ MEV-Protected Path (Private Bundles) │
│ User → Direct to Producer → Microblock (if conditions met) │
│ ↓ │
│ Fallback to Public Mempool (if rejected/timeout) │
└─────────────────────────────────────────────────────────────┘
Bundle Constraints (Production Tested ✅):
| Constraint | Value | Purpose |
|---|---|---|
| Max TXs per Bundle | 10 | Prevent block space monopolization |
| Reputation Gate | 80%+ | Proven trustworthy nodes only |
| Gas Premium | +20% | Economic incentive for inclusion |
| Max Lifetime | 60 seconds | 60 microblocks max (prevent stale bundles) |
| Rate Limiting | 10 bundles/min per user | Anti-spam protection |
| Block Allocation | 0-20% dynamic | 80-100% guaranteed for public TXs |
| Multi-Producer Submission | 3 producers | Redundancy and load distribution |
| Signature Verification | Dilithium3 | Post-quantum security |
Dynamic Allocation Algorithm:
Block Composition (per microblock):
├── Step 1: Calculate bundle demand
│ └── total_bundle_txs / max_txs_per_block
├── Step 2: Apply dynamic allocation (cap at 20%)
│ └── 0% (no demand) → 20% (high demand)
├── Step 3: Include bundles atomically
│ └── All TXs or none (atomic inclusion)
└── Step 4: Fill remaining with public TXs (80-100%)
└── Priority: highest gas_price first
Key Property: Public transaction throughput is ALWAYS protected (80% minimum allocation)!
Implementation: BTreeMap-based priority queue for anti-spam protection
pub struct SimpleMempool {
by_gas_price: BTreeMap<u64, VecDeque<String>>, // Priority queue
transactions: DashMap<String, TxStorage>, // Fast lookup
}Features:
- ✅ Gas-Price Ordering: Highest gas price processed first
- ✅ Anti-Spam Protection: Low-gas TXs cannot block high-value TXs
- ✅ FIFO within Same Price: Fair ordering for identical gas prices
- ✅ O(log n) Insertion: Efficient priority queue operations
- ✅ Min Gas Price: 100,000 nano QNC (0.0001 QNC base fee)
Example:
500,000 nano QNC → TX_1, TX_2 (processed first)
200,000 nano QNC → TX_3, TX_4
100,000 nano QNC → TX_5, TX_6 (processed last)
Byzantine Safety:
- ✅ Post-Quantum Signatures: All bundles verified with Dilithium3
- ✅ Reputation Gate: Only 80%+ reputation nodes can submit
- ✅ Multi-Producer Submission: 3 producers for redundancy
- ✅ Atomic Inclusion: All bundle TXs verified before inclusion
- ✅ Public TX Protection: 80-100% guaranteed allocation
Economic Incentives:
- ✅ Gas Premium: +20% payment for bundle inclusion
- ✅ Priority Queue: Bundles compete by total_gas_price
- ✅ Rate Limiting: Prevents spam from single users
- ✅ Auto-Fallback: Failed bundles → public mempool
Scalability:
- ✅ Light Nodes: NOT affected (don't produce blocks)
- ✅ Full Nodes: Can submit bundles if reputation ≥80%
- ✅ Super Nodes: Full MEV protection capabilities
- ✅ Lock-Free: DashMap for concurrent bundle operations
Production Test Suite (11/11 Passed) ✅:
- Bundle size validation (empty/oversized rejected)
- Reputation check (70% rejected, 80%+ accepted)
- Time window validation (max 60s enforced)
- Gas premium validation (+20% required)
- Rate limiting (10 bundles/min per user)
- Bundle priority queue (by total_gas_price)
- Dynamic allocation (0-20% based on demand)
- Bundle validity check (time window enforcement)
- Bundle cleanup (expired bundles removed)
- Config defaults (all values correct)
- Priority mempool integration (highest gas first)
Real-World Validation:
- ✅ Reputation gate: default 70% → rejected (no bypass!)
- ✅ Priority ordering: 500k → 200k → 100k gas_price
- ✅ Dynamic allocation: 0% (no demand) → 100% public TXs
- ✅ Bundle lifetime: 60s = 60 microblocks < 90s macroblock

## 8. Technical Innovations
### 8.1 Quantum-Resistant Signatures
**CRYSTALS-Dilithium implementation:**
```rust
pub struct QNetSignature {
pub algorithm: "CRYSTALS-Dilithium",
pub security_level: 128, // bit post-quantum security
pub signature: Vec<u8>, // 2420 bytes
pub public_key: Vec<u8>, // 1312 bytes
}
Signing process:
- Generate cryptographic hash of transaction (SHA3-256)
- Create Dilithium signature
- Verification using public key
- Add to block
Multi-level validation:
- Cryptographic: Verification of quantum-resistant signatures
- Consensus: Byzantine validation from multiple nodes
- Economic: Balance and fee verification
- Network: Validation from regional clusters
RocksDB with optimizations:
- Column families: Separation by data types
- Compression: Zstd for 40-60% size reduction
- Block cache: Acceleration of frequently requested data
- Archiving: Automatic compression of old blocks
Node-Specific Storage Requirements:
| Node Type | Storage | Data Stored |
|---|---|---|
| Light | 50-100 MB | Headers ONLY (no blocks, no transactions) |
| Full | ~50 GB | Sliding window (100K blocks) + snapshots |
| Super | 400+ GB | Full history with archival |
Pruning System (v2.19.7):
| Pruning Type | What is Removed | Trigger |
|---|---|---|
| Block Pruning | Old microblocks/macroblocks | Sliding window (100K blocks) |
| Transaction Pruning | Old TX data from 3 CFs | After block pruning |
| Microblock Pruning | Microblocks after macroblock | After finalization |
| Snapshot Cleanup | Old state snapshots | Keep last 5 only |
Storage Savings:
- Without pruning: 2+ TB/year (transactions grow forever)
- With pruning: ~260 GB (sliding window)
- Savings: ~87%
Snapshot System:
- Full snapshots: Every 12 hours
- Incremental snapshots: Every 1 hour
- Compression: Zstd-15 (~70% reduction)
- Integrity: SHA3-256 verification
- Auto-cleanup: Last 5 snapshots only
QNet implements cutting-edge performance optimization techniques to achieve maximum throughput and minimal latency:
Efficient block distribution mechanism:
Block → Chunks (1KB each) → Reed-Solomon Encoding → Fanout Distribution
Key features:
- Chunked Transmission: Blocks split into 1KB chunks for efficient network usage
- Reed-Solomon Erasure Coding: 1.5x redundancy factor for packet loss recovery
- Fanout-3 Protocol: Each node forwards to 3 peers, creating exponential propagation
- Kademlia DHT Routing: XOR distance-based peer selection for optimal routing
- Bandwidth Reduction: 85% savings compared to full broadcast
Technical implementation:
pub struct Shred ProtocolChunk {
block_hash: [u8; 32],
chunk_index: u32,
total_chunks: u32,
data: Vec<u8>, // 1KB max
parity: bool, // true for Reed-Solomon parity chunks
}Performance metrics:
- Maximum block size: 43.5MB (170 × 256KB chunks) - supports 100K+ TPS (v2.63)
- Block creation limit: 40MB (defense against network deadlock)
- Propagation time: O(log₃(N)) where N = network size
- Packet loss tolerance: Up to 33% with full recovery
Chunk Retransmit Mechanism (v2.21.3):
When chunks are lost during propagation, the retransmit mechanism enables efficient recovery without downloading entire blocks:
1. Node detects missing chunks after 3-second timeout
2. Sends RequestMissingChunks to 3-10 peers (adaptive based on network size)
3. Peers respond with cached chunks from last 100 blocks
4. Node reconstructs block with recovered chunks + Reed-Solomon
| Network Size | Peers Queried | Success Rate* |
|---|---|---|
| 5-100 nodes | 3-5 | 87-97% |
| 100-10K nodes | 5-7 | 97-99% |
| 10K-100K nodes | 7-8 | 99%+ |
*Assuming 50% cache hit rate
Bandwidth savings:
- Request 2 missing chunks: 2KB vs 12KB full block = 83% savings
- Request 5 missing chunks: 5KB vs 12KB full block = 58% savings
QUIC Rate Limiting (v2.21.4):
Without rate limiting, burst of 72+ concurrent QUIC streams causes receiver overload and ~40% packet loss. Solution: Semaphore-based adaptive rate limiting.
// Adaptive limit based on network size and per-peer capacity
let max_concurrent = min(network_limit, peer_count * 5);| Network Size | Network Limit | Per-Peer (×5) | Effective |
|---|---|---|---|
| 5 nodes | 20 | 25 | 20 |
| 50 nodes | 50 | 250 | 50 |
| 500 nodes | 100 | 2500 | 100 |
| 5000 nodes | 200 | 25000 | 200 |
Benefits:
- ✅ Chunks remain independent (Reed-Solomon compatible)
- ✅ No head-of-line blocking
- ✅ QUIC flow control works correctly
- ✅ Scales to 100K+ nodes
Cryptographic clock for precise time synchronization:
QNet's Quantum Verifiable Time Sequence provides a verifiable, sequential record of events using cryptographic hashing:
Algorithm:
// Hybrid implementation for optimal performance/security
for i in 0..HASHES_PER_TICK {
if i % 4 == 0 {
// Every 4th hash: SHA3-512 for sequential ordering (limits parallelization)
VTS_n = SHA3_512(VTS_{n-1} || counter)
} else {
// Other hashes: Blake3 for speed (3x faster)
VTS_n = Blake3(VTS_{n-1} || counter)
}
}Technical specifications:
- Hash Rate: 500K hashes per second (5,000 per tick × 100 ticks/sec)
- Algorithm: Hybrid SHA3-512/Blake3 (25%/75% ratio for sequential ordering)
- Sequential Property: SHA3-512 every 4th hash creates bottleneck (NOT formal VDF)
- Tick Duration: 10 milliseconds (5,000 hashes per tick)
- Ticks Per Slot: 100 ticks = 1 second = 1 microblock slot
- Drift Detection: Maximum 5% allowed drift before correction
- Verification: Each node can independently verify VTS sequence
- Memory: Fixed-size arrays (64 bytes), zero Vec allocations in hot path
Benefits:
- Time Synchronization: Network-wide consensus on event ordering
- Sequential Ordering: Proof that computation occurred in sequence (NOT formal VDF delay proof)
- No Clock Dependency: Cryptographic proof instead of system clocks
- Byzantine Resistance: 67%+ coalition required to manipulate (finality window protection)
- Limitation: Biasable by controlling entropy source (past block hashes)
Implementation:
pub struct VTSEntry {
num_hashes: u64, // Sequential counter
hash: Vec<u8>, // SHA3-512 output (64 bytes)
data: Option<Vec<u8>>, // Optional transaction/event data
timestamp: u64, // Unix timestamp in microseconds
}
// Optimized generation loop
let mut hash_bytes = [0u8; 64];
for i in 0..HASHES_PER_TICK {
let mut hasher = Sha3_512::new();
hasher.update(&hash_bytes);
hasher.update(&counter.to_le_bytes());
hash_bytes.copy_from_slice(&hasher.finalize());
}Deterministic Producer Selection with Finality Window:
QNet uses SHA3-512 deterministic selection with a 10-block Finality Window:
- Quantum-Resistant: SHA3-512 hashing with Dilithium-signed blocks
- Deterministic: All synchronized nodes compute identical results from finalized entropy
- Race-Free: Finality Window eliminates race conditions at rotation boundaries
- Byzantine-Safe: Uses blocks confirmed by 2/3 consensus as entropy source
- Simplicity: No per-node VRF keys required, easier verification
- Fairness: 7/10 - Biasable by 67%+ Byzantine coalition (economically expensive)
Algorithm:
// Finality Window: Get entropy from finalized block (10+ blocks old)
async fn get_finalized_entropy(
current_height: u64,
storage: &Storage
) -> [u8; 32] {
const FINALITY_WINDOW: u64 = 10;
if current_height <= FINALITY_WINDOW {
// Early blocks: Use Genesis + height for variation
let genesis_data = storage.load_microblock(0)?;
let mut hasher = Sha3_256::new();
hasher.update(&genesis_data);
hasher.update(¤t_height.to_le_bytes());
return hasher.finalize().into();
} else {
// Normal: Use block 10 blocks behind current
let entropy_height = current_height - FINALITY_WINDOW;
let entropy_block = storage.load_microblock(entropy_height)?;
// UNIFIED v2.36: SHA3-512 everywhere for maximum quantum security
return Sha3_512::digest(&entropy_block).into();
}
}
// Deterministic Producer Selection (all nodes compute same result)
async fn select_microblock_producer(
current_height: u64,
candidates: &[(String, f64)],
storage: &Storage,
) -> String {
// Step 1: Get finalized entropy (all nodes have this block)
let entropy = get_finalized_entropy(current_height, storage).await;
// Step 2: Combine with round and candidates for selection
let mut selector = Sha3_512::new();
selector.update(b"QNet_Quantum_Producer_Selection_v3");
selector.update(&entropy);
selector.update(&(current_height / 30).to_le_bytes());
for (id, rep) in candidates {
selector.update(id.as_bytes());
selector.update(&rep.to_le_bytes());
}
// Step 3: Deterministic selection
let hash = selector.finalize();
let index = u64::from_le_bytes(hash[0..8].try_into()?) % candidates.len();
return candidates[index].0.clone();
}Producer Selection Process:
1. Finality Window Enforcement:
- FINALITY_WINDOW = 10 blocks
- Finalized height = current_height - 10
- All synchronized nodes have blocks up to finalized_height
- Lagging nodes (>10 blocks behind) cannot participate
2. Entropy Extraction (Deterministic):
For blocks 1-10 (Genesis phase):
- entropy = SHA3_256(Genesis block + current_height)
- All nodes have Genesis, height adds variation
For blocks 11+ (Normal phase):
- entropy = SHA3_256(microblock[finalized_height])
- Uses block that all synchronized nodes possess
- Block is Dilithium-signed (quantum-resistant)
3. Candidate Selection Input:
- Combine entropy + round + candidates via SHA3-512
- input = SHA3_512("QNet_..." || entropy || round || candidates)
- Deterministic: same inputs → same output
4. Producer Selection:
- Convert hash to index: hash[0..8] % candidates.len()
- Select producer = candidates[index]
- All nodes compute identical result
5. Byzantine Safety Verification:
- Entropy block verified by Dilithium signatures
- 2/3 consensus confirms block validity
- Race conditions impossible (entropy finalized 10 blocks ago)
Technical specifications:
- Cryptography: SHA3-512 deterministic hashing + Dilithium-signed entropy blocks
- Quantum Resistance: Full post-quantum security (NIST approved SHA3-512 + Dilithium)
- Finality Window: 10 blocks (10 seconds lag tolerance)
- Selection Time: <1ms (single SHA3-512 hash computation)
- Entropy Sources: Finalized block hash + round number + candidate list
- Deterministic: All synchronized nodes compute identical result
- Race-Free: No race conditions at rotation boundaries (blocks 31, 61, 91)
- Synchronization: Nodes must be within 10 blocks to participate
Benefits:
- Quantum-Resistant: SHA3-512 + Dilithium-signed blocks = full PQC
- Deterministic: 100% consensus on producer selection (no race conditions)
- No Race Conditions: Finality Window eliminates boundary issues
- Byzantine Safety: Entropy from 2/3-confirmed blocks (biasable by 67%+ coalition)
- Simple: Deterministic SHA3-512, no VRF keys or threshold calculations
- No Coordination: Each node independently computes same result
- Scalable: O(1) computation, works from 5 to millions of nodes
- Limitation: Not true VRF randomness, weaker than private-key VRF schemes
Implementation:
pub struct FinalityWindowSelection {
selected_producer: String, // Selected node ID

Technical capabilities:
- Max Parallel Transactions: 10,000 simultaneous executions
- Dependency Graph: Automatic conflict detection using read/write sets
- Shard Integration: Works seamlessly with 10,000-shard architecture
- Cross-Shard Support: Handles cross-shard transactions with 2-phase commit
Performance characteristics:
Sequential execution: 1,000 TPS
Parallel execution: 424,411 TPS (424x speedup)
Transaction types supported:
- Token transfers (intra-shard and cross-shard)
- Node activation
- Smart contract deployment
- Smart contract calls
Dynamic consensus timeouts based on network conditions:
Adaptive BFT implements adaptive timeout mechanisms to optimize consensus under varying network conditions:
Timeout schedule:
- Block #1: 20 seconds (network bootstrap phase)
- Blocks #2-10: 10 seconds (network stabilization)
- Blocks #11+: 7 seconds (normal operation)
Adaptive features:
- Exponential Backoff: 1.5x multiplier for retries
- Network Awareness: Adjusts based on peer latency and packet loss
- Failover Protection: Prevents false positives during synchronization
- Byzantine Tolerance: Maintains 3f+1 safety under all conditions
Benefits:
- Prevents premature failovers during network startup
- Adapts to network congestion automatically
- Maintains consensus safety while maximizing liveness
- Reduces unnecessary producer rotations
Speculative transaction processing for reduced latency:
Future block producers pre-execute transactions before their turn:
Technical specifications:
- Lookahead: 3 blocks ahead
- Cache Size: 10,000 pre-executed transactions
- Pre-execution Batch: Up to 1,000 transactions per batch
- Timeout: 500ms per pre-execution batch
- Cache Cleanup: Automatic removal of stale entries
Process:
- Node predicts it will be producer in 3 blocks
- Pre-executes transactions from mempool
- Caches results (state changes, gas used)
- When turn arrives, uses cached results
- Validates cache is still valid (no conflicts)
Performance impact:
- Cache Hit Rate: 70-90% typical
- Latency Reduction: 40-60% for cached transactions
- Throughput Increase: 15-25% overall
Metrics tracked:
pub struct PreExecutionMetrics {
cache_hits: u64,
cache_misses: u64,
pre_executed: u64,
cache_invalidations: u64,
avg_speedup: f64,
}Commit-Reveal Byzantine Fault Tolerance - QNet's unique consensus:
Features:
- Protection from "nothing at stake" attacks
- Prevention of voting manipulation
- Finalization through information disclosure
- Resistance to 33% malicious nodes
- Block-based phase synchronization (v2.40): All nodes in same phase at same height
90-Block Epoch Structure:
| Blocks | Phase | Duration | Purpose |
|---|---|---|---|
| 1-60 | Production | 60s | Microblock creation only |
| 61-72 | Commit | 12s | Validators submit encrypted votes |
| 73-84 | Reveal | 12s | Validators reveal votes |
| 85-90 | Finalize | 6s | Leader creates MacroBlock |
Phase Determination:
// DETERMINISTIC: All nodes compute IDENTICAL phase from height
fn get_phase_for_block(height: u64) -> ConsensusPhase {
match height % 90 {
0 => Finalize, // Block 90, 180, 270...
1..=60 => Production, // Microblocks only
61..=72 => Commit, // Submit commits
73..=84 => Reveal, // Submit reveals
85..=89 => Finalize, // Create MacroBlock
}
}Grace Periods (Network Tolerance):
- Commits accepted: blocks 61-78 (includes early Reveal grace)
- Reveals accepted: blocks 69-90 (includes late Commit and Finalize grace)
Commit Message:
commit = {
round_id: u64,
validator_id: String,
commit_hash: SHA3_256(vote + nonce),
timestamp: u64,
signature: CRYSTALS_Dilithium_signature
}Reveal Message:
reveal = {
round_id: u64,
validator_id: String,
vote: String, // Real vote
nonce: Vec<u8>, // Random number
timestamp: u64,
signature: CRYSTALS_Dilithium_signature
}Finalization:
- Verification: SHA3_256(vote + nonce) == commit_hash
- Count votes from valid reveals
- Consensus at 2f+1 agreeing votes
Previous behavior: Nodes that committed but didn't reveal were jailed (1h+) Current behavior: Only -1% reputation penalty (no jail)
Rationale:
- Timing issues may be caused by network latency, not malicious intent
- Cannot cryptographically prove if miss was intentional
- Prevents cascade jailing that kills the network
Cryptographically deterministic selection:
- Genesis phase: All 5 Genesis nodes participate
- Normal phase: Sampling up to 1000 best validators
- Selection criteria:
- Reputation 70+ points (consensus_threshold = 70.0)
- Node type: Super or Full
- Active network connectivity
- Blockchain synchronization
