Sui Foundation reported 40,614,180 transactions per second during an October 7 demonstration at Sui Basecamp in Singapore. The result was measured inside Sui tunnels, programmable offchain channels whose outcomes settle to Sui mainnet. It is not a measurement of 40 million separate transactions being written to the base layer every second.
The official announcement says the test exceeded its 20 million TPS target and the 6,086,766 TPS figure reported during a July 4 demonstration. Mysten Labs co-founder Adeniyi Abiodun led the event. The Foundation describes CertiK as the real-time verifier, while also saying a detailed report examining the evidence will follow in the coming days.
Crypto Briefing's report makes the same architectural distinction: activity occurs away from the main chain, and the final state is settled onchain. Its coverage corroborates the announcement's existence and context, but does not substitute for access to the underlying benchmark records.
For developers comparing throughput figures, the measured layer is the central question. Counting interactions within channels and counting individually executed base-layer transactions describe different workloads. A larger number alone does not establish that two systems were tested under equivalent conditions.
The announced result is therefore a demonstration milestone, rather than evidence of sustained application demand or a guarantee of production performance. The statement does not provide the full execution logs, test-duration breakdown or reproducible workload configuration needed to independently reconstruct the headline figure.
Those details are the next useful evidence to inspect. The forthcoming review should clarify what was counted, how throughput changed over the measurement window and how settlement related to the offchain activity. Until then, the 40.6 million figure should remain attributed to the demonstration, with its offchain scope kept alongside the number.
