●●SolidBig BrainSolve My ProblemShip It

Beats zstd by 12% on Ethereum JSON by decoding hex and delta-encoding fields first.

Strengths
  • Live mainnet benchmarks verify lossless compression gains on real blocks, not synthetic data.
  • Composable primitives like hex decoding and delta encoding target Ethereum-specific verbosity.
  • Python demo fetches live data without API keys, enabling immediate independent reproducibility.
Weaknesses
  • Python demo only; no production-ready Rust or Go library for high-throughput node integration.
  • Requires pipeline changes to insert transform layer, unlike drop-in compression upgrades.
