Mysten Labs released Sui testnet v1.80.1 with Protocol 137 updates

2 min

Mysten Labs released Sui testnet v1.80.1 built on protocol version 137. The build updates protocol logic, GraphQL, JSON-RPC, and archival services, and is limited to testnet. It does not represent a Sui mainnet upgrade.

What’s in protocol version 137

Cryptography and performance: Ristretto255 range-proof verification costs less and supports larger batch verification.
Data access and subscriptions: The GraphQL subscription root is now in the production schema for operators that enable it.
Archival services: The Bigtable-backed gRPC archival service adds broader package-query support.
Execution and fees: Adjustments to execution logic and gas accounting under protocol 137.

These changes target developers and operators who maintain wallets, indexers, trading systems, and applications that rely on consistent data and RPC behavior.

Scope and implications

Deployment status: v1.80.1 is testnet-only. Observed performance and behavior do not apply to mainnet.
Purpose: Testnet releases allow operators and developers to validate compatibility and catch regressions before promotion to production.
Ecosystem impact: Teams will focus on compatibility across GraphQL, JSON-RPC, and execution changes to ensure tools continue functioning when traffic and state scale up.
Next step: The key outcome is which protocol 137 changes reach mainnet and how smoothly the ecosystem absorbs them.

Sui’s rapid release cadence increases the value of testnet staging for preventing production incidents while iterating on data services, cryptographic verification, and execution behavior.
