Mysten Labs Publishes Sui Testnet v1.80.1 with Protocol 137 Features

Mysten Labs has made the Sui testnet v1.80.1 available, showcasing the upcoming protocol version 137. The release touches multiple layers of the stack, including Move execution, RPC interfaces and archival infrastructure, and is intended for developers and node operators to evaluate before any mainnet rollout.

Key Protocol 137 Enhancements

• Ristretto255 range‑proof verification is now cheaper and supports larger batch sizes.
• The GraphQL subscription root is added to the production schema for operators that enable it.
• Archival services gain broader package‑query support via a Bigtable‑backed gRPC service.
• Adjustments to execution and gas‑accounting behavior under the new protocol version.

Impact on Ecosystem Participants

While the changes are not directly visible to most SUI holders, they affect wallets, indexers, trading platforms and applications that rely on accurate network data. Updates to GraphQL, JSON‑RPC and execution logic may require tooling adjustments to maintain compatibility.

Testnet Status and Next Steps

v1.80.1 is a testnet build and should not be considered a live mainnet upgrade. Its purpose is to allow operators to identify compatibility issues before the changes are potentially promoted to mainnet. The broader question remains which of these protocol 137 features will graduate to mainnet and how smoothly the ecosystem will adopt them.
