Sui Testnet Release Adds Protocol 137 Features for Validators
Version 1.80.1 expands validator controls, archival gRPC access and GraphQL capabilities while introducing execution changes for developers.
Sui testnet v1.80.1 introduces protocol version 137 with changes aimed at validators, infrastructure operators and developers across the network’s execution and application programming interfaces.
The Tuesday, Sept. 22, release makes Ristretto255 range-proof verification cheaper and increases the commitment-times-range-bit limit from 512 to 1,024. The higher limit allows larger batches to be processed in a single call. Protocol 137 also adds the allowances feature.
On devnet, the update moves object-funds withdrawal sufficiency checks into the Move virtual machine. The first settled-balance read for each (owner, type) pair costs 184 internal gas units.
The release also changes how LdConst gas charges are calculated. The charge now uses abstract value size instead of serialized byte length, slightly increasing costs for code that relies heavily on constants.
Validators can opt into a consensus-transaction-pool configuration that selects transactions from a gas-price-prioritized pool during block proposals. The change gives node operators an additional configuration option for how transactions enter proposed blocks.
For infrastructure operators, the Bigtable-backed archival gRPC service adds MovePackageService methods covering packages, datatypes, functions and package versions. GraphQL’s Subscription root for checkpoints, events and transactions is now included in the production schema, although operators must still enable subscriptions.
The release is tagged for Sui’s testnet and is not itself a mainnet upgrade. Sui also has a separate mainnet-v1.80.1 release dated Wednesday, Sept. 23, using protocol version 137.
