refactor(coordinator): standardize database path to follow blockchain-node pattern
- Change coordinator database from /opt/data/coordinator.db to ./data/coordinator.db - Update config.py to use relative path consistent with blockchain-node - Update deployment scripts to use /opt/coordinator-api/data/coordinator.db - Add data directory creation in init_db() for consistency - Update .env.example files to reflect new standard - Maintain backward compatibility for production deployment

# GPU Acceleration Research for ZK Circuits - Implementation Findings
|
||||
|
||||
## Executive Summary
|
||||
|
||||
Completed comprehensive research into GPU acceleration for ZK circuit compilation and proof generation in the AITBC platform. Established clear implementation path with identified challenges and solutions.
|
||||
|
||||
## Current Infrastructure Assessment
|
||||
|
||||
### Hardware Available
|
||||
- **GPU**: NVIDIA RTX 4060 Ti (16GB GDDR6)
|
||||
- **CUDA Capability**: 8.9 (Ada Lovelace architecture)
|
||||
- **Memory**: 16GB dedicated GPU memory
|
||||
- **Performance**: Capable of parallel processing for ZK operations
|
||||
|
||||
### Software Stack
|
||||
- **Circom**: Circuit compilation (working, ~0.15s for simple circuits)
|
||||
- **snarkjs**: Proof generation (no GPU support, CPU-only)
|
||||
- **Halo2**: Research library (0.1.0-beta.2, API compatibility challenges)
|
||||
- **Rust**: Available (1.93.1) for GPU-accelerated implementations
|
||||
|
||||
## GPU Acceleration Opportunities
|
||||
|
||||
### 1. Circuit Compilation Acceleration
|
||||
**Current State**: Circom compilation is fast for simple circuits (~0.15s)
|
||||
**GPU Opportunity**: Parallel constraint generation for large circuits
|
||||
**Implementation**: CUDA kernels for polynomial evaluation and constraint checking
|
||||
|
||||
### 2. Proof Generation Acceleration
|
||||
**Current State**: snarkjs proof generation is compute-intensive
|
||||
**GPU Opportunity**: FFT operations and multi-scalar multiplication
|
||||
**Implementation**: GPU-accelerated cryptographic primitives
|
||||
|
||||
### 3. Witness Generation Acceleration
|
||||
**Current State**: Node.js based witness calculation
|
||||
**GPU Opportunity**: Parallel computation for large witness vectors
|
||||
**Implementation**: CUDA-accelerated field operations
|
||||
|
||||
## Implementation Challenges Identified
|
||||
|
||||
### 1. snarkjs GPU Support
|
||||
- **Finding**: No built-in GPU acceleration in current snarkjs
|
||||
- **Impact**: Cannot directly GPU-accelerate existing proof workflow
|
||||
- **Solution**: Custom CUDA implementations or alternative proof systems
|
||||
|
||||
### 2. Halo2 API Compatibility
|
||||
- **Finding**: Halo2 0.1.0-beta.2 has API differences from documentation
|
||||
- **Impact**: Circuit implementation requires version-specific adaptations
|
||||
- **Solution**: Use Halo2 for research, focus on practical implementations
|
||||
|
||||
### 3. CUDA Development Complexity
|
||||
- **Finding**: Full CUDA implementation requires specialized knowledge
|
||||
- **Impact**: Significant development time for production-ready acceleration
|
||||
- **Solution**: Start with high-impact optimizations, build incrementally
|
||||
|
||||
## Recommended Implementation Strategy
|
||||
|
||||
