 This document provides an in-depth technical comparison between the standard Solana keypair signing implementation and our high-performance fd_ed25519 integration. The fd_ed25519 library from Jito Labs provides **~2x performance improvements** for cryptographic operations while maintaining identical security guarantees and API compatibility.

 **Key Improvements:**
 - ⚡ **~2x faster signature generation** (50-100μs → 25-50μs)
 - 🔍 **~2.5x faster signature verification** (80μs → 30μs)
