Overview
- Sui said a live demo on Wednesday, October 7, 2026, recorded 40,614,180 transactions per second using programmable off‑chain “tunnels,” with CertiK verifying the figure in real time.
- The 40.6 million TPS number measures activity inside tunnels that batch interactions off chain and settle only when a tunnel is closed, so each interaction was not written individually to the base layer.
- Mysten Labs ran the test on the Summit Stage at Sui Basecamp in Singapore, opened more than 10,000 tunnels within seconds, and exceeded an internal 20 million TPS target and a July 4 record of about 6.1 million TPS.
- CertiK will examine proofs, execution logs and journals and publish an independent report in the coming days, and that audit will determine how the live figure maps to sustained, real‑world capacity.
- If the result proves reproducible, it could enable high‑frequency machine and AI agent commerce by cutting intermediate gas costs and moving most activity off chain with on‑chain verifiable settlement.
