PROOFNEST

⚠️ DEPRECATED: This is proofnest v1.x (legacy). Please upgrade to v2.0.0+

pip install proofnest>=2.0.0

What's new in v2.0:

• Go blockchain backend (10x faster, production-grade)
• STRICT_CRYPTO mode (no silent fallbacks)
• HYBRID signatures (ML-DSA + Ed25519)
• AI inference receipts
• GPT-5.2 security audit fixes

Migration guide: https://proofnest.io/migration

Proof, not promises.

Quantum-proof Layer 1 blockchain with AI work verification. Every transaction cryptographically signed with post-quantum Dilithium3. Genesis anchored to Bitcoin via OpenTimestamps.

v1.5.0 - Full Blockchain Implementation

This release includes the complete PROOFNEST blockchain node (14,800+ lines) with:

• 257 comprehensive tests - Full coverage including security tests
• Dilithium3 signatures - NIST PQC Level 3 quantum-proof
• SHAKE256 hashing - Domain-separated, collision-resistant
• TLS 1.3 P2P - Encrypted peer communication with TOFU pinning
• LMD-GHOST fork choice - Proper fork handling
• AI Work Validator - TF-IDF + entropy verification with slashing
• Staking system - 50 PROOF minimum, 21-day unbonding
• EIP-1559 gas model - Base fee burning mechanism

Genesis Allocations

Quick Start

Run a Node

from proofnest.node import P2PNode

# Genesis node (creates new chain)
node = P2PNode(
    name="genesis-node",
    host="127.0.0.1",
    port=9001,
    is_genesis=True
)
node.start()

# Validator node (joins existing chain)
validator = P2PNode(
    name="validator-1",
    host="127.0.0.1",
    port=9002,
    peers=["127.0.0.1:9001"]
)
validator.start()

Multi-Node Testnet

# Set data directory per node
export HONEST_CHAIN_DIR=/path/to/node1/data

# Optional: Disable TLS for testing
export PROOFNEST_NO_TLS=1

# Run testnet launcher
python run_testnet.py

AI Work Submission

from proofnest.node import AIWorkValidator

validator = AIWorkValidator()

# Submit AI work for verification
result = validator.verify_work(
    input_data="Analyze quarterly financial report",
    output_data="Revenue increased 15% YoY...",
    task_type="analysis",
    compute_time=45.2,
    stake=1000  # PROOF tokens at stake
)

# Slashing for poor quality work
if result["quality_score"] < 0.5:
    slash_amount = result["slash_amount"]  # Up to 10% of stake

Decision Logging (SDK)

from proofnest import ProofNest, RiskLevel

pn = ProofNest(agent_id="my-agent")
print(pn.did)  # did:pn:a1b2c3...

pn.decide(
    action="Approved transaction",
    reasoning="All checks passed",
    risk_level=RiskLevel.HIGH  # Auto-anchored to Bitcoin
)

assert pn.verify()

Security

Quantum-Proof Cryptography

• Dilithium3 - NIST ML-DSA-65, Level 3 security
• 1952-byte public keys - Larger but quantum-safe
• SHAKE256 - Extensible output function

Anti-Replay Protection

# Every transaction includes:
{
    "nonce": 42,           # Sequential per-sender
    "chain_id": "proofnest-mainnet",
    "expires_at": 1735900000  # 1 hour default
}

Fork Handling

• LMD-GHOST fork choice rule
• Automatic chain reorganization
• Persistent storage survives restarts

Testing

# Run all 257 tests
python -m pytest tests/ -v

# Security tests only
python -m pytest tests/ -k "security" -v

# With coverage
python -m pytest tests/ --cov=proofnest --cov-report=html

Components

Configuration

Environment Variables

Staking Parameters
