Phase 7, Milestone 1: Security

Security audits and hardening for mainnet

Status: 🔄 In Progress Priority: Critical (Pre-Mainnet) Components: All crates

---

Overview

Conduct comprehensive security audits of all cryptographic code, consensus logic, and critical components. Establish bug bounty program and formal verification where applicable.

---

Tasks

Task 1.1: Cryptographic Code Audit

• External audit of synor-crypto
• Review Ed25519 implementation usage
• Review Dilithium3 integration
• Verify hybrid signature scheme
• Check key derivation functions
• Audit encryption implementations

Files to Audit:

• crates/synor-crypto/src/ed25519.rs
• crates/synor-crypto/src/dilithium.rs
• crates/synor-crypto/src/hybrid.rs
• crates/synor-crypto/src/encryption.rs
• crates/synor-crypto/src/kdf.rs

Validation Agents:

Agent	Purpose
code-reviewer	Initial code review
silent-failure-hunter	Check error handling
External Auditor	Professional security audit

Security Checklist:

• No timing side channels
• Constant-time comparisons
• Proper RNG seeding
• Key material zeroing
• No private key logging

Task 1.2: Consensus Logic Audit

• External audit of synor-consensus
• Review GHOSTDAG implementation
• Verify UTXO management
• Check difficulty adjustment
• Audit block validation
• Review transaction validation

Files to Audit:

• crates/synor-consensus/src/block_validator.rs
• crates/synor-consensus/src/transaction_validator.rs
• crates/synor-consensus/src/utxo.rs
• crates/synor-consensus/src/difficulty.rs
• crates/synor-dag/src/ghostdag.rs

Security Checklist:

• No double-spend possible
• Difficulty adjustment secure
• No block malleability
• Proper coinbase handling
• Fork resolution correct

Task 1.3: Formal Verification

• Define critical invariants
• Model key algorithms
• Verify GHOSTDAG properties
• Verify consensus rules
• Document proofs

Verification Targets:

Property	Method	Status
UTXO conservation	TLA+	Pending
No double-spend	Property testing	✅ Done
Difficulty convergence	Mathematical proof	Pending
DAG ordering determinism	Kani	Pending

Task 1.4: Bug Bounty Program

• Define scope and rules
• Set reward tiers
• Create submission process
• Establish response SLA
• Launch publicly

Reward Tiers:

Severity	Reward
Critical	$50,000 - $100,000
High	$10,000 - $50,000
Medium	$2,500 - $10,000
Low	$500 - $2,500

Scope:

• Cryptographic vulnerabilities
• Consensus bugs
• Network attacks
• Smart contract vulnerabilities
• Denial of service
