Why this fork exists

c-kzg-4844 is the canonical KZG commitment library for EIP-4844 / Verkle. luxcpp/crypto consumes it via FetchContent for the kzg/ body (LP-137 sibling #103); lux/crypto Go layer wraps it via github.com/ethereum/c-kzg-4844/v2.

Owning the fork lets luxfi pin a specific commit per release branch and avoid breaking changes between upstream v2.x minor bumps.

Sync policy

• Track upstream v2.x releases only.
• Pull upstream tags into sync/<tag> branches. Audit the diff. Re-run KZG KATs in luxcpp/crypto/kzg. Merge to main only after KATs pass.
• Trusted setup updates require explicit luxfi-crypto-team review. Never auto-sync setup files.
