-## Project Overview
-
-Nym is a privacy platform that uses mixnet technology to protect against metadata surveillance. The platform consists of several key components:
-- Mixnet nodes (mixnodes) for packet mixing
-- Gateways (entry/exit points for the network)
-- Clients for interacting with the network
-- Network monitoring tools
-- Validators for network consensus
-- Various service providers and integrations

-
-## Architecture
-
-The Nym platform consists of various components organized as a monorepo:
-
-1. **Core Mixnet Infrastructure**:
-   - `nym-node`: Core binary supporting mixnode and gateway modes
-   - `common/nymsphinx`: Implementation of the Sphinx packet format
-   - `common/topology`: Network topology management
-   - `common/types`: Shared data types across components
-
-2. **Network Monitoring**:
-   - `nym-network-monitor`: Monitors the network's reliability and performance
-   - `nym-api`: API server for network stats and monitoring data
-   - Metrics tracking for nodes, routes, and overall network health
-
-3. **Client Implementations**:
-   - `clients/native`: Native Rust client implementation
-   - `clients/socks5`: SOCKS5 proxy client for standard applications
-   - `wasm`: WebAssembly client implementations (for browsers)
-   - `nym-connect`: Desktop and mobile clients
-
-4. **Blockchain & Smart Contracts**:
-   - `common/cosmwasm-smart-contracts`: Smart contract implementations
-   - `contracts`: CosmWasm contracts for the Nym network
-   - `common/ledger`: Blockchain integration
-
-5. **Utilities & Tools**:
-   - `tools`: Various CLI tools and utilities
-   - `sdk`: SDKs for different languages and platforms
-   - `documentation`: Documentation generation and management
-
-## Packet System
-
-Nym uses a modified Sphinx packet format for its mixnet:
-
-1. **Message Chunking**:
-   - Messages are divided into "sets" and "fragments"
-   - Each fragment fits in a single Sphinx packet
-   - The `common/nymsphinx/chunking` module handles message fragmentation
-
-2. **Routing**:
-   - Packets traverse through 3 layers of mixnodes
-   - Routing information is encrypted in layers (onion routing)
-   - The final gateway receives and processes the messages
-
-3. **Monitoring**:
-   - Monitoring system tracks packet delivery through the network
-   - Routes are analyzed for reliability statistics
-   - Node performance metrics are collected
-
-## Network Protocol
-
-Nym implements the Loopix mixnet design with several key privacy features:
-
-1. **Continuous-time Mixing**:
-   - Each mixnode delays messages independently with an exponential distribution
-   - This creates random reordering of packets, destroying timing correlations
-   - Offers better anonymity properties than batch mixing approaches
-
-2. **Cover Traffic**:
-   - Clients and nodes generate dummy "loop" packets that circulate through the network
-   - These packets are indistinguishable from real traffic
-   - Creates a baseline level of traffic that hides actual communication patterns
-   - Provides unobservability (hiding when and how much real traffic is being sent)
-
-3. **Stratified Network Architecture**:
-   - Traffic flows through Entry Gateway → 3 Mixnode Layers → Exit Gateway
-   - Path selection is independent per-message (unlike Tor)
-   - Each node connects only to adjacent layers
-
-4. **Anonymous Replies**:
-   - Single-Use Reply Blocks (SURBs) allow receiving messages without revealing identity
-   - Enables bidirectional communication while maintaining privacy
-
-## Network Monitoring Architecture
-
-The network monitoring system is a core component that measures mixnet reliability:
-
-1. The `nym-network-monitor` sends test packets through the network
-2. These packets follow predefined routes through multiple mixnodes
-3. Metrics are collected about:
-   - Successful and failed packet deliveries
-   - Node reliability (percentage of successful packet handling)
-   - Route reliability (which specific route combinations work best)
-4. Results are stored in the database and used by `nym-api` to:
-   - Present node performance statistics
-   - Determine network rewards
-   - Provide route selection guidance to clients
-
-In the current branch, metrics collection is being enhanced with a fanout approach to submit to multiple API endpoints.

-## Common Issues and Troubleshooting
-
-### Database Issues
-
-- When modifying database queries, you must update SQLx query caches:
-  ```bash
-  cargo sqlx prepare
-  ```
-- If you see SQLx errors about missing query files, this is likely the cause
-- For "database is locked" errors with SQLite, ensure only one process accesses the DB
-- For PostgreSQL connection issues, verify DATABASE_URL and that the server is running
-
-### API Connection Issues
-
-- Check the environment variables pointing to the APIs (NYM_API, NYXD)
-- Verify network connectivity and API health endpoints
-- For authentication issues, check node keys and credentials
-- Common endpoints to verify:
-  - API health: `$NYM_API/health`
-  - Chain status: `$NYXD/status`
-  - Contract info: `$NYXD/cosmwasm/wasm/v1/contract/$CONTRACT_ADDRESS`
-
-### Build Problems
-
-- Clean dependencies with `cargo clean` for a fresh build
-- Check for compatible Rust version (1.80+ recommended)
-- For smart contract builds, ensure wasm-opt is installed: `npm install -g wasm-opt`
-- For cross-compilation issues, check target-specific dependencies
-- WASM build issues: Ensure wasm32-unknown-unknown target is installed:
-  ```bash
-  rustup target add wasm32-unknown-unknown
-  ```
-- For "cannot find -lpq" errors, install PostgreSQL development files:
-  ```bash
-  # Ubuntu/Debian
-  sudo apt-get install libpq-dev
-  # macOS
-  brew install postgresql
-  ```
-
-### Environment Issues
-
-- Contract address mismatches: Ensure you're using the correct environment file
-- "Account sequence mismatch": The account nonce is out of sync, wait and retry
-- Token decimal issues: Sandbox uses different decimal places than mainnet
-- API version mismatches: Ensure your local API version matches the network
-- "Insufficient funds": Get test tokens from faucet (sandbox) or check balance
-- Gateway/mixnode bonding issues: Verify minimum stake requirements
-
-## Working with Routes and Monitoring
-
-1. Route monitoring metrics are stored in a `routes` table with:
-   - Layer node IDs (layer1, layer2, layer3, gw)
-   - Success flag (boolean)
-   - Timestamp
-
-2. To analyze routes:
-   - Check `NetworkAccount` and `AccountingRoute` in `nym-network-monitor/src/accounting.rs`
-   - View monitoring logic in `common/nymsphinx/chunking/monitoring.rs`
-   - Observe how routes are submitted to the database in the `submit_accounting_routes_to_db` function
-
-## Performance Optimization
-
-### Profiling and Benchmarking
-
-```bash
-# Run benchmarks
-cargo bench -p nym-node
-
-# Profile with perf (Linux)
-cargo build --release --features profiling
-perf record --call-graph=dwarf ./target/release/nym-node run --mode mixnode
-perf report
-
-# Generate flamegraph
-cargo install flamegraph
-cargo flamegraph --bin nym-node -- run --mode mixnode
-```
-
-### Common Performance Considerations
-
-- Use bounded channels for backpressure
-- Batch database operations where possible
-- Monitor memory usage with `RUST_LOG=nym_node::metrics=debug`
-- Use connection pooling for database connections
-- Consider using `jemalloc` for better memory allocation performance
