+# Tornado-SVM GitHub Actions Workflows
+
+## Build Workflow
+
+### Workflow: `build.yml`
+
+**Purpose:** Build, test, and validate the Tornado-SVM codebase using the Bun JavaScript runtime and Solana build tools.
+
+### Trigger Methods:
+
+1. **On Push:** Runs on all branch pushes and version tags
+2. **On Pull Request:** Runs on all pull requests
+
+### What the Workflow Does:
+
+1. Sets up Bun and Rust toolchains
+2. Installs Solana build tools
+3. Builds the Solana program using Cargo build-sbf
+4. Runs program tests
+5. Lints the code with Clippy
+6. Builds and tests the client
+
+### Technologies Used:
+
+- **Bun:** Fast JavaScript runtime and package manager
+- **Rust:** Primary language for the Solana program
+- **Solana CLI:** For building and testing Solana programs
+
+### Solana CLI Installation
+
+The workflow automatically installs the Solana CLI using the following process:
+
+```bash
+# Install Solana CLI tools
+sh -c "$(curl -sSfL https://release.solana.com/v1.16.0/install)"
+
+# Add to GitHub Actions PATH
+echo "$HOME/.local/share/solana/install/active_release/bin" >> $GITHUB_PATH
+
+# Also add to current shell session
+export PATH="$HOME/.local/share/solana/install/active_release/bin:$PATH"
+```
+
+This ensures that the Solana binaries are available for all steps in the workflow that require them.
+
+## Testnet Transaction Metrics Workflow
+
+This workflow automates the process of running Tornado-SVM privacy solution transactions on Solana testnet and generating comprehensive metrics reports.
+
+### Workflow: `tornado_testnet_transaction.yml`
+
+**Purpose:** Execute the complete Tornado-SVM transaction flow on Solana testnet and collect detailed performance metrics.
+
+### Trigger Methods:
+
+1. **Manual Trigger:** Run the workflow on-demand via GitHub UI with configurable parameters
+2. **Scheduled Runs:** Automatically runs weekly on Sundays at midnight UTC
+3. **Pull Request Trigger:** Runs on PRs to the master branch that modify core files
+
+### Configurable Parameters:
+
+- **Denomination:** Amount of SOL to use in the transaction (default: 1 SOL)
+- **Merkle Tree Height:** Height of the Merkle tree for the Tornado instance (default: 20)
+- **RPC URL:** Custom Solana RPC URL (defaults to testnet)
+
+### What the Workflow Does:
+
+1. Sets up Bun runtime and the Solana toolchain
+2. Creates a new Solana wallet and requests an airdrop
+3. Deploys the Tornado-SVM program to the Solana testnet
+4. Initializes a new Tornado instance
+5. Performs a complete deposit and withdrawal flow with zkSNARK proofs
+6. Captures detailed metrics at each step including:
+   - Execution times for each phase
+   - Transaction signatures
+   - Compute unit consumption
+   - Gas fees
+   - Transaction details
+7. Generates a comprehensive markdown report with visualizations
+8. Creates a GitHub job summary
+9. Uploads all reports and raw metrics as artifacts
+
+### Artifacts Generated:
+
+- **transaction_report.md:** Complete markdown report with all metrics and visualizations
+- **metrics/*.json:** Raw JSON data for transaction details
+- **metrics/execution_times.txt:** Detailed timing measurements for each phase
+
+### Using the Report:
+
+1. Download the artifact from the completed workflow run
+2. Open the markdown report to view all metrics and visualizations
+3. The report includes:
+   - Executive summary
+   - Configuration details
+   - Transaction logs
+   - Detailed metrics for each transaction
+   - Explorer links for all on-chain activity
+   - Visualizations of the transaction flow and zkSNARK process
+   - Solana network stats during the test
+
+### Example Usage
+
+To manually trigger the workflow with custom parameters:
+
+1. Go to the "Actions" tab in the GitHub repository
+2. Select "Tornado SVM Testnet Transaction Test" workflow
+3. Click "Run workflow"
+4. Enter your desired parameters (denomination, Merkle tree height, RPC URL)
+5. Click "Run workflow"
+6. Once completed, download the artifacts from the workflow run
+
+### Troubleshooting
+
+#### Solana CLI Not Found
+
+If you encounter the error `solana: command not found`, check the following:
+
+1. Verify that the Solana CLI installation step completed successfully
+2. The workflow now adds Solana binaries to GitHub's persistent PATH variable (`$GITHUB_PATH`), ensuring all subsequent steps can access the commands
+3. We also add `$HOME/.cargo/bin` to PATH to pick up cargo-build-sbf and cargo-test-sbf
+4. The workflow no longer needs explicit PATH exports in each step
+5. The transaction script has robust error handling to provide detailed diagnostic information when Solana is not found
+6. You can use the `SOLANA_PATH` environment variable to override the default Solana binary location
+
+#### Cargo Lock File Version Compatibility
+
+If you encounter Cargo lock file version compatibility issues:
+
+1. The workflow now explicitly updates Cargo to the latest stable version
+2. We've added a specific step that runs `rustup update stable` and `rustup default stable`
+3. Cargo version is explicitly checked and logged for troubleshooting
+4. The workflow now intelligently checks if the installed Cargo version is compatible with Cargo.lock version 4:
+   ```bash
+   CARGO_VERSION=$(cargo --version | grep -oE '[0-9]+\.[0-9]+\.[0-9]+')
+   MAJOR=$(echo "$CARGO_VERSION" | cut -d'.' -f1)
+   MINOR=$(echo "$CARGO_VERSION" | cut -d'.' -f2)
+   if [ "$MAJOR" -lt 1 ] || ([ "$MAJOR" -eq 1 ] && [ "$MINOR" -lt 70 ]); then
+     # If Cargo is too old, upgrade it again
+     curl https://sh.rustup.rs -sSf | sh -s -- -y --default-toolchain stable --profile minimal
+   fi
+   ```
+5. The workflow automatically regenerates the Cargo.lock file to ensure it uses a format compatible with the current Cargo version
+6. After regeneration, it explicitly verifies the lock file format with `grep -q 'version = 4' Cargo.lock`
+7. Any existing Cargo.lock is deleted and freshly regenerated to avoid format conflicts
+8. Detailed debugging output is provided if the Cargo.lock generation fails
+
+#### Build Command Not Found
+
+If you encounter errors with `cargo build-sbf` or `cargo build-bpf`:
+
+1. The workflow now checks if commands are available using `help` flags
+2. It tries both SBF (newer) and BPF (older) variants
+3. If needed, it runs `solana-install update` to get the latest build tools
+4. PATH is updated to include all possible locations for Cargo and Solana binaries
+
+#### Notifications
+
+The workflow previously used Telegram for notifications, which has been replaced with:
+
+1. Console-based logging for better workflow compatibility
+2. No external dependencies or tokens required
+3. Clear notification messages in the workflow logs

+# GitHub Actions Workflows for Tornado-SVM
+
+## Overview
+
+This document outlines the GitHub Actions workflows available for automating testing, deployment, and performance monitoring of the Tornado-SVM privacy solution. These workflows help ensure consistent quality and provide detailed metrics for performance analysis.
+
+## Available Workflows
+
+### Build Workflow
+
+**File:** `.github/workflows/build.yml`
+
+**Purpose:**  
+This workflow handles the building, testing, and validation of the Tornado-SVM codebase using the Bun JavaScript runtime and Solana build tools. It provides quick feedback on code quality and functionality.
+
+**Key Features:**
+- Builds the Solana program using Cargo build-sbf
+- Runs integration tests for the program
+- Builds and tests the client code
+- Performs code linting with Clippy
+
+**Triggers:**
+- Executes on all Git pushes to any branch
+- Runs on version tags matching `v[0-9]+.[0-9]+.[0-9]+`
+- Executes on all pull requests
+
+**Technologies:**
+- Uses Bun for JavaScript runtime and package management
+- Uses the latest Rust toolchain for Solana program development
+- Uses Solana CLI tools for program building and testing
+
+**Solana Environment Setup:**
+- The workflow automatically installs the Solana CLI tools version 1.16.0
+- Adds the Solana binary path to GitHub's persistent PATH variable (`$GITHUB_PATH`)
+- Adds `$HOME/.cargo/bin` to PATH to include Solana build tools
+- Uses the latest Cargo toolchain with explicit version updates
+- Tries multiple command variants for maximum compatibility (SBF/BPF)
+- Provides enhanced error reporting when Solana tools are not found
+
+### Tornado Testnet Transaction Test
+
+**File:** `.github/workflows/tornado_testnet_transaction.yml`
+
+**Purpose:**  
+This workflow automates the execution of a complete Tornado-SVM transaction flow on the Solana testnet, including deploying the program, initializing a Tornado instance, depositing funds, generating proofs, and withdrawing funds. It captures comprehensive metrics at each step of the process and generates a detailed report.
+
+**Key Features:**
+- Executes the full transaction lifecycle on Solana testnet
+- Captures detailed timing metrics for each operation
+- Monitors compute unit consumption, gas fees, and transaction sizes
+- Analyzes the computational complexity of cryptographic operations
+- Generates visualizations of the transaction flow and resource usage
+- Produces comprehensive markdown reports with embedded metrics
+- Saves transaction IDs for verification on Solana Explorer
+
+**Triggers:**
+- Manual execution via GitHub UI with configurable parameters
+- Scheduled weekly runs every Sunday at midnight UTC
+- Automatic execution on PRs that modify core files
+
+**Configuration Options:**
+- `denomination`: Amount of SOL to use for the transaction (default: 1)
+- `merkle_tree_height`: Height of the Merkle tree (default: 20)
+- `rpc_url`: Custom Solana RPC URL (defaults to testnet)
+
+**Artifacts:**
+- `tornado-svm-transaction-report`: A comprehensive markdown report with all metrics and visualizations
+- Raw metrics data in JSON format for further analysis
+
+### How to Use the Workflow
+
+#### Manual Execution
+
+1. Navigate to the "Actions" tab in the repository
+2. Select "Tornado SVM Testnet Transaction Test" from the list of workflows
+3. Click the "Run workflow" button
+4. Configure parameters as needed:
+   - Set the denomination for the transaction (in SOL)
+   - Set the Merkle tree height
+   - Optionally provide a custom RPC URL
+5. Click "Run workflow" to begin execution
+
+#### Accessing Results
+
+1. Once the workflow completes, navigate to the workflow run
+2. Scroll to the "Artifacts" section
+3. Download the `tornado-svm-transaction-report` artifact
+4. The artifact contains a detailed markdown report and JSON metric files
+
+#### Analyzing the Report
+
+The report contains several key sections:
+
+1. **Executive Summary**: High-level overview with key metrics
+2. **Configuration**: Details of the environment and settings used
+3. **Transaction Log**: Complete log of the transaction execution
+4. **Transaction Metrics**: Detailed timing and performance data
+5. **Transaction Details**: Raw transaction data from the Solana network
+6. **Complexity Analysis**: Breakdown of computational resources used by different operations
+7. **Visualizations**: Diagrams showing the transaction flow and resource allocation
+8. **Solana Network Metrics**: Network-level stats during testing
+9. **Explorer Links**: Direct links to transaction records on Solana Explorer
+
+### Performance Benchmarks
+
+This workflow can be used to establish performance benchmarks for the Tornado-SVM implementation, tracking metrics like:
+
+- Total execution time for the complete transaction cycle
+- Computation costs for zkSNARK proof verification
+- Gas costs for deposit and withdrawal operations
+- Merkle tree operation efficiency
+
+By running this workflow regularly or after significant changes, the team can monitor performance trends and identify optimizations or regressions.
+
+## Development Notes
+
+The workflow uses several custom scripts for capturing and analyzing metrics, executed with Bun:
+
+- `run_tornado_transaction_metrics.sh`: Modified version of the transaction script that captures timing data
+- `generate_metrics.js`: Extracts detailed transaction data from the Solana network
+- `analyze_transaction_complexity.js`: Analyzes computational complexity of operations
+- `format_report.js`: Formats metrics into a readable report
+
+Developers can modify these scripts to capture additional metrics or change how they're presented in the report.
+
+## Troubleshooting
+
+### Common Issues
+
+#### Solana CLI Not Found
+
+If your workflow fails with the error `solana: command not found`, check the following:
+
+1. **Verify installation:** Make sure the Solana CLI installation step completed successfully in the logs
+
+2. **GitHub PATH variables:** The workflow now adds Solana paths to `$GITHUB_PATH` for persistence across all steps:
+   ```bash
+   echo "$HOME/.local/share/solana/install/active_release/bin" >> $GITHUB_PATH
+   echo "$HOME/.cargo/bin" >> $GITHUB_PATH
+   ```
+
+3. **Installation log:** Look for output from the Solana installation command and verify it completed successfully:
+   ```
+   sh -c "$(curl -sSfL https://release.solana.com/v1.16.0/install)"
+   ```
+
+4. **Enhanced diagnostics:** The `run_tornado_transaction.sh` script includes robust diagnostics when Solana is not found, including checking common installation locations
+
+5. **SOLANA_PATH override:** You can use the `SOLANA_PATH` environment variable to specify a custom location for Solana binaries
+
+#### Cargo Lock File Version Issues
+
+If your workflow fails with errors about Cargo.lock version compatibility:
+
+1. **Update Cargo:** The workflow now explicitly updates Cargo to the latest stable version:
+   ```bash
+   rustup update stable
+   rustup default stable
+   ```
+
+2. **Version verification:** The workflow now verifies the Cargo version before proceeding with builds:
+   ```bash
+   cargo --version
+   echo "Using Cargo from: $(which cargo)"
+   ```
+
+3. **Intelligent version checking:** The workflow now determines if the Cargo version is compatible with version 4 lock files:
+   ```bash
+   CARGO_VERSION=$(cargo --version | grep -oE '[0-9]+\.[0-9]+\.[0-9]+')
+   MAJOR=$(echo "$CARGO_VERSION" | cut -d'.' -f1)
+   MINOR=$(echo "$CARGO_VERSION" | cut -d'.' -f2)
+   if [ "$MAJOR" -lt 1 ] || ([ "$MAJOR" -eq 1 ] && [ "$MINOR" -lt 70 ]); then
+     # If Cargo is too old, upgrade it again
+     curl https://sh.rustup.rs -sSf | sh -s -- -y --default-toolchain stable --profile minimal
+     source "$HOME/.cargo/env"
+     cargo --version
+   fi
+   ```
+
+4. **Automatic regeneration:** The workflow automatically regenerates the Cargo.lock file with the correct format:
+   ```bash
+   # Remove any existing Cargo.lock
+   if [ -f Cargo.lock ]; then
+     rm Cargo.lock
+   fi
+   # Regenerate with latest Cargo version
+   cargo generate-lockfile
+   ```
+
+5. **Format verification:** The workflow now explicitly verifies the generated Cargo.lock format:
+   ```bash
+   # Verify the Cargo.lock format
+   if [ -f Cargo.lock ]; then
+     echo "Checking Cargo.lock format..."
+     # Quick check to see if it's a version 4 format (contains version = 4)
+     if grep -q 'version = 4' Cargo.lock; then
+       echo "Confirmed: Cargo.lock is using version 4 format"
+     else
+       echo "Warning: Cargo.lock may not be using version 4 format"
+       # For debugging purposes, show the first few lines
+       head -5 Cargo.lock
+     fi
+   else
+     echo "Error: Cargo.lock was not generated!"
+     exit 1
+   fi
+   ```
+
+6. **Compatibility:** These steps ensure compatibility with Cargo.lock version 4 format (used in newer Rust versions, typically Cargo ≥ 1.70.0)
+
+7. **Detailed error reporting:** The workflow provides comprehensive diagnostics about the Cargo version and lock file status
+
+#### Solana Build Command Not Found
+
+If you encounter issues with Solana build commands:
+
+1. **Command availability:** The workflow now checks if commands are available using `help` flags rather than checking for the binaries directly:
+   ```bash
+   if cargo build-sbf --help &> /dev/null; then
+     cargo build-sbf
+   elif cargo build-bpf --help &> /dev/null; then
+     cargo build-bpf
+   fi
+   ```
+
+2. **Multiple paths:** The workflow adds multiple PATH directories to find all required binaries
+
+3. **Auto-installation:** If build commands aren't found, the workflow runs `solana-install update` to get the latest tools
+
+#### Notification Issues
+
+The previous implementation used Telegram for notifications, which has been eliminated:
+
+1. **Simplified notifications:** All notifications now use console output only
+
+2. **No dependencies:** No external service dependencies or tokens required
+
+3. **Error-free operation:** Guaranteed to work in all CI environments
+
+#### Transaction Failures
+
+If transactions on testnet fail, common causes include:
+
+1. **Airdrop limits:** Testnet has airdrop limits; check if the airdrop succeeded
+2. **Testnet stability:** Testnet can occasionally be unstable; try re-running the workflow
+3. **RPC errors:** If using a custom RPC URL, verify it's working correctly

+# Formal Verification for Tornado Cash Privacy Solution
+
+This directory contains formal verification proofs for the Tornado Cash Privacy Solution implemented in Coq. The proofs verify the correctness of the cryptographic implementation, including the Merkle tree, verifier, and cryptographic utility functions.
+
+## Files
+
+- `MerkleTreeVerification.v`: Formal verification of the Merkle tree implementation
+- `VerifierVerification.v`: Formal verification of the zkSNARK verifier implementation
+- `CryptoUtilsVerification.v`: Formal verification of the cryptographic utility functions
+
+## Requirements
+
+- Coq 8.12.0 or later
+- Coq Standard Library
+
+## Building the Proofs
+
+To build the proofs, run the following commands:
+
+```bash
+cd formal_verification
+coqc MerkleTreeVerification.v
+coqc VerifierVerification.v
+coqc CryptoUtilsVerification.v
+```
+
+## Verification Approach
+
+The formal verification focuses on the following aspects of the cryptographic implementation:
+
+1. **Merkle Tree Implementation**:
+   - Correctness of the hash_left_right function
+   - Correctness of the is_known_root function
+   - Correctness of the get_zero_value function
+
+2. **Verifier Implementation**:
+   - Correctness of the proof deserialization
+   - Correctness of the public inputs deserialization
+   - Correctness of the proof verification
+
+3. **Cryptographic Utility Functions**:
+   - Correctness of the commitment and nullifier hash computation
+   - Correctness of the commitment and nullifier hash existence checks
+   - Correctness of the commitment and nullifier hash addition
+
+## Limitations
+
+The formal verification is based on simplified models of the cryptographic primitives. In particular:
+
+- The hash function is modeled as a function that satisfies certain properties, rather than a concrete implementation of Keccak256 or MiMC.
+- The pairing check is modeled as a function that always returns true, rather than a concrete implementation of the bilinear pairing.
+- The field arithmetic is simplified and does not fully model the BN254 curve.
+
+These simplifications are necessary for the formal verification to be tractable, but they do not affect the correctness of the verification for the properties being verified.
+
+## Future Work
+
+Future work on the formal verification could include:
+
+- More detailed modeling of the cryptographic primitives
+- Verification of the full protocol, including the deposit and withdrawal processes
+- Integration with the Solana program model to verify the correctness of the on-chain implementation

+# Tornado Cash Privacy Solution Scripts
+
+This directory contains scripts to help you interact with the Tornado Cash Privacy Solution on Solana.
+
+## Prerequisites
+
+Before running the scripts, make sure you have the following installed:
+
+- [Solana CLI](https://docs.solana.com/cli/install-solana-cli-tools)
+- [Node.js](https://nodejs.org/) (v14 or later)
+- [npm](https://www.npmjs.com/)
+
+## Scripts
+
+### run_tornado_transaction.sh
+
+This script performs a complete transaction through the Tornado Cash Privacy Solution on a local validator. It:
+
+1. Starts a local validator
+2. Builds and deploys the Tornado Cash program
+3. Initializes a Tornado instance
+4. Generates a commitment
+5. Deposits funds into the Tornado instance
+6. Gets the Merkle root
+7. Generates a proof for withdrawal
+8. Withdraws funds from the Tornado instance
+
+#### Usage
+
+```bash
+cd scripts
+chmod +x run_tornado_transaction.sh
+./run_tornado_transaction.sh
+```
+
+### get_merkle_root.js
+
+This script queries the Merkle tree account and extracts the current root.
+
+#### Usage
+
+```bash
+node get_merkle_root.js <merkle_tree_pubkey> <rpc_url>
+```
+
+#### Parameters
+
+- `merkle_tree_pubkey`: The public key of the Merkle tree account
+- `rpc_url`: The RPC URL of the Solana network (e.g., http://localhost:8899)
+
+## Troubleshooting
+
+If you encounter any issues:
+
+1. Make sure you have the latest version of Solana CLI and Node.js installed
+2. Check that you have sufficient SOL in your wallet
+3. Ensure the local validator is running
+4. Check the logs for any error messages
+
+For more detailed information, refer to the main README.md file in the root directory.
