Sui Blockchain Hits 40.6M TPS in AI Agent Stress Test
Sui's offchain tunnels logged 40.6 million transactions per second during a live test simulating heavy AI agent traffic.
If you've ever wondered how fast a blockchain can actually move when things get serious, Sui just gave us a pretty jaw-dropping answer. The layer-1 blockchain recently clocked 40.6 million transactions per second (TPS) using its programmable offchain tunnels — and this wasn't a lab simulation cooked up in ideal conditions. It happened during a live stress test built to mimic the kind of chaotic, high-frequency activity you'd expect from AI agents firing messages at each other constantly.
So what exactly are these "tunnels" Sui is talking about? Think of offchain tunnels as express lanes that let data and transactions move outside the main blockchain highway, avoiding congestion while still staying connected to the network's security. By making them programmable, Sui gives developers the ability to customize how those lanes behave — which is a big deal if you're building apps that need to process enormous volumes of tiny transactions quickly, like AI systems that communicate in rapid bursts.

The 40.6 million TPS figure is staggering when you put it in context. For comparison, traditional payment networks like Visa typically handle tens of thousands of transactions per second at peak. Hitting eight digits puts Sui in a completely different conversation — though it's worth noting that offchain throughput and fully settled onchain transactions are different beasts, and the crypto industry has a long history of benchmark numbers that look better on paper than in real-world conditions.
Still, the timing of this test is telling. AI agents — autonomous software programs that execute tasks and interact with each other without human hand-holding — are becoming a serious topic in both the tech and crypto worlds. A blockchain that can genuinely support the transaction volume these agents might generate would have a real competitive edge as that market matures. Sui is clearly positioning itself as the infrastructure layer for that future.
Whether this benchmark translates into actual developer adoption and real-world use cases remains to be seen, but it's a compelling opening argument. Continue reading at Cointelegraph.
