-- **Inter-AS connectivity**: Latency and reachability between regions -- **Bandwidth utilization**: Traffic patterns and congestion -- **Partition detection**: Network splits and healing -- **BGP convergence**: Routing table updates and stability - -### Blockchain Metrics - -Monitor blockchain-specific metrics: - -- **Block propagation**: Time for blocks to reach all regions -- **Transaction latency**: End-to-end transaction confirmation time -- **Fork resolution**: Consensus behavior during network partitions -- **Mining distribution**: Hash rate distribution across regions - -## Testing Scenarios - -### 1. Geographic Distribution Testing - -**Objective**: Validate blockchain performance across global regions - -**Test Steps**: -1. Deploy full testnet -2. Generate transactions from each region -3. Monitor block propagation times -4. Measure transaction confirmation latency - -**Expected Results**: -- Blocks propagate within 30-60 seconds globally -- Transaction finality varies by region (10s NA, 60s satellite) -- No consensus failures during normal operation - -### 2. Network Partition Testing - -**Objective**: Test consensus resilience during network splits - -**Test Steps**: -1. Start testnet in normal operation -2. Simulate partition isolating one region -3. Monitor consensus behavior -4. Heal partition and observe recovery - -**Expected Results**: -- Consensus continues in majority partition -- Minority partition stops producing blocks -- Recovery occurs within 5-10 minutes after healing - -### 3. Performance Under Constraint Testing - -**Objective**: Validate operation under bandwidth/latency constraints - -**Test Steps**: -1. Deploy testnet with realistic constraints -2. Generate high transaction load -3. Monitor system performance -4. Identify bottlenecks and limitations - -**Expected Results**: -- Graceful degradation under load -- Mobile/satellite nodes maintain connectivity -- Transaction throughput scales with network capacity - -### 4.

Layer-specific settings (gas limits, difficulty, retention periods) +- **Layer configs** - Each layer has its own configuration struct with sensible defaults +- **Test configurations** - Special configurations for testing (e.g., difficulty=0 for fast mining) ## Development Guidelines ### Code Quality Standards -The project maintains a **zero dead code policy**: - -- All code must be actively used (no `#[allow(dead_code)]`) -- Zero compiler warnings allowed -- Comprehensive test coverage (100+ tests) -- Strict Clippy compliance - -### Testing Architecture - **Current Status** -- **Unit Tests**: Located alongside source files (`*_tests.rs`) -

-### Configuration Management -Configuration files are in `/config`: -- `modular.toml` - Modular architecture settings -- `diamond_io.toml` - Diamond IO configuration -- `polytorus.toml` - General blockchain settings -- `docker-node.toml` - Docker deployment configuration - -### Dependencies & Build Requirements - -**Essential Dependencies:** -- **Rust**: 1.82+ (not 1.87 - that was incorrect) -- **OpenFHE**: MachinaIO fork with `exp/reimpl_trapdoor` branch (must be at `/usr/local`) -- **System Libraries**: `cmake`, `libgmp-dev`, `libntl-dev`, `libboost-all-dev` - -**OpenFHE Installation:** -```bash -# Automated installation -sudo ./scripts/install_openfhe.sh - -# Set required environment variables -export OPENFHE_ROOT=/usr/local -export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH -export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH -``` -

WalletError enum for various wallet operations. - Developed HD wallet structure with mnemonic generation and key derivation methods. - Introduced KeyPair management for Ed25519 and secp256k1 cryptographic schemes. - Implemented Signature struct with verification utilities for Ed25519 and secp256k1 signatures. - Created Wallet and WalletManager for managing multiple wallets and signing operations. - Added unit tests for all major functionalities to ensure correctness and reliability. --- Cargo.lock | 383 +++++++++++++++++- Cargo.toml | 4 +- crates/wallet/Cargo.toml | 72 ++++
