Sui sets a new record of 40.6 million TPS in AI-driven offline testing
Sui, the Layer-1 blockchain developed by Mysten Labs, achieved 40.6 million transactions per second (TPS) in real-time testing of its Programmable Offchain Tunnels. This achievement marks a major leap forward in its performance, far exceeding the historical benchmark of approximately 6.1 million TPS set in similar stress tests in July this year.
Real-time demonstration of breaking the blockchain speed bottleneck
The stress test was conducted during the Sui Basecamp event held in Singapore on Wednesday. The Sui engineering team aims to simulate high-frequency trading environments, especially trading scenarios involving autonomous artificial intelligence (AI) agents. In this real-time demonstration, the peak processing rate of off-chain transactions reached 40,614,180 times per second.
According to Sui officials, more than 10,000 programmable offline tunnels were running on the main network during the event. These channels support a variety of activities including payments, games and chat applications. These tunnels are specifically designed to support loads that are too high for direct processing on the chain due to data volume and speed requirements.
Adeniyi Abiodun, co-founder and chief product officer of Sui, elaborated on the vision: "Sui is built for an era when millions of AI agents are trading every day."
Deep understanding of programmable down-chain tunnels
Sui's programmable off-chain tunnels are special channels that allow users or software agents to perform large numbers of fast transactions. Instead of recording every event on the chain, these tunnels package activities and settle the final state onto the blockchain only when the tunnel closes. This approach significantly improves throughput by reducing on-chain congestion and reducing network costs.
The goal of this test is to simulate real-world application scenarios in which hundreds of thousands of autonomous or semi-autonomous AI agents may be trading simultaneously. This is an increasing focus of many blockchain platforms seeking to meet the needs of future artificial intelligence applications.
Noun explanation: Sui programmable off-chain tunnel
This is an extension technology located on the Sui blockchain that allows high-speed batch processing of transactions outside the main chain, thereby improving throughput and efficiency, and settling only necessary data on the chain.
Audit and Industry Oversight
Well-known blockchain security company CertiK served as an external observer for this demonstration. The company, known for its independent audit, is currently reviewing technical data collected during testing and plans to release a verification report in the next few days.
CertiK's participation as an independent auditor of multiple blockchain projects aims to ensure the integrity and accuracy of Sui's results presented at this high-profile benchmark event.
Background and Future Outlook
Mysten Labs, the main developer of Sui, positioned the platform as a solution to the scalability challenges that hinder widespread adoption of blockchain, especially in areas that require fast and high-volume transaction processing. By focusing on high-throughput infrastructure, Sui aims to attract industries such as artificial intelligence, games and payments that have extremely high requirements for transaction frequency.
Industry observers are closely watching whether Sui's off-chain expansion strategy can maintain similar performance under broader decentralization conditions and ultimately translate into practical advantages for end users and developers.
