Sui’s testnet v1.74.1 release brings two key protocol updates that refine network behavior without affecting user interfaces.
The first change adds protocol version 128, which introduces explicit bounds for binary pools. Previously, these pools were only implicitly constrained, leading to potential ambiguity in pool sizing. By making the bounds explicit, the protocol now provides clearer limits for developers and validators.
The second update addresses a mis‑release in version 126. Protocol version 127 is reinstated to enable the always_advance_dkg_to_resolution flag. This flag ensures that the Distributed Key Generation (DKG) process moves to resolution automatically, improving the reliability of validator key management.
Both changes are internal and do not alter any user‑visible features. They are intended to enhance the robustness and predictability of the Sui testnet’s underlying protocol.
Developers can review the pull requests on GitHub for detailed code changes and can test the new protocol versions in their local environments. The release is available for download from the official Sui GitHub repository.
These updates underscore Sui’s ongoing commitment to refining its protocol layer while maintaining a stable developer experience.
