During a live demonstration at the Sui Basecamp conference in Singapore on October 7, 2026, the Sui network processed a record 40,614,180 transactions per second using its programmable off-chain "tunnels" architecture. Independent auditor CertiK verified the performance in real time. Mysten Labs co-founder Adeniyi Abiodun positioned the test as critical infrastructure for an upcoming economy of autonomous AI agents.
Record-breaking transaction throughput
- ▪During a live demonstration on October 7, 2026, the Sui blockchain network processed 40,614,180 transactions per second, surpassing its target of 20 million transactions per second
- ▪The October 7, 2026 throughput of 40,614,180 transactions per second is more than six times Sui's previous record of 6,086,766 transactions per second set on July 4, 2026
CertiK's verification
- ▪As independent auditor, CertiK verified Sui's 40,614,180 transactions per second figure in real time on October 7, 2026, by examining proofs, execution logs, journals, and supporting evidence, and plans to publish a performance report
- ▪During the October 7, 2026 test at the Sui Basecamp conference in Singapore, CertiK monitored Sui's effective transactions per second, which counts activity that happens off the main blockchain
Sui tunnel technology and deployment
- ▪Sui tunnels are programmable off-chain state channels that allow parties to exchange transactions off-chain and settle the final state on the Sui mainnet when closed
- ▪During the October 7, 2026 demonstration at the Sui Basecamp conference in Singapore, more than 10,000 Sui tunnels were opened on the Sui mainnet within seconds of each other across categories including chat, games, and payments
Infrastructure for autonomous AI agents
- ▪Sui is positioning its high-throughput tunnel architecture as the trust and transaction infrastructure for autonomous AI agents and machine-speed commerce
- ▪Adeniyi Abiodun stated that while human markets do not require millions of transactions per second, autonomous AI agents transacting daily will require high-speed infrastructure such as Sui's tunnel architecture
Debatable claims
- ▪Sui's off-chain tunnel transactions represent a legitimate measure of blockchain throughput
- ▪Live third-party auditing is sufficient to validate blockchain performance claims
- ▪High-throughput blockchain demonstrations are primarily marketing exercises rather than technical milestones
- ▪Sui's tunnel architecture compromises blockchain security for the sake of speed
