Sui Processes Over 6 Million Transactions Per Second in AI Agent Livestream Experiment

On July 4, 2026, Sui achieved a network throughput of 6,086,766 transactions per second during a public livestream experiment, surpassing its previous benchmark of 297,000 TPS by over 20 times. The demonstration involved AI agents competing in games, payments, and chat using an explorer that allowed participants to log in via Gmail through Sui’s zkLogin feature. All transactions were processed offchain through programmable tunnels, which settle to the Sui mainnet upon closure, ensuring gasless interactions for users. Participants received test tokens (MTPS) and could engage in activities like blackjack, Quantum Poker, and shared canvas drawing without prior SUI holdings or gas fees.

Kostas Chalkias, Chief Cryptographer and Co-Founder at Mysten Labs, highlighted the broader implications of the experiment, stating that programmable tunnels enable agent-to-agent commerce, competitive gaming, and prediction markets at massive scale without direct onchain interaction. He suggested potential real-world applications, such as offline payments during emergencies, where funds could be locked offchain and accessed once connectivity is restored. The experiment underscored the versatility of programmable tunnels beyond traditional payments, positioning them as a potential fifth major product-market fit in crypto alongside stablecoins, DeFi, payments, and prediction markets.

Mysten Labs and the Sui hacker team plan to expand the technology’s capabilities, including confidential transfers via Nautilus, multi-party tunnels, and agent-to-agent prediction markets. The livestream, which documented the event, is available for review, showcasing Sui’s infrastructure supporting high-performance blockchain applications. The company emphasized the importance of broad participation for decentralization and network success, with initiatives like Sui Education Grants aimed at onboarding new developers.

Sui’s recent milestones include a $450 million PIPE deal bringing institutional capital and expanding SUI trading access, as well as integration with over 15 million Phantom wallet users globally. The network’s advancements, such as the kiosk primitive used in *The Walking Dead Lands* and new Web3 gaming titles, reflect its growing ecosystem and adoption in high-performance blockchain applications.
