During June 2025, Kyungun Lee upgraded the cryptographic stack for the kaiachain/kaia repository, focusing on enhancing build reliability and future-proofing the project. Lee implemented the KZG 4844 upgrade to version 1.1.0 in Go, refactoring API signatures to accept pointers to Blob types for improved memory management and compatibility. He also synchronized dependency versions in go.sum, aligning gnark-crypto and go-internal libraries to ensure reproducible builds across development and CI environments. This work strengthened the project’s security posture, reduced the risk of runtime issues, and positioned Kaia to support upcoming zk-SNARK features through robust cryptography and package management.
