The Sui Network has achieved a major blockchain performance milestone after reaching an estimated 6 million transactions per second (TPS) during the live “Sui Tunnels Experiment.” The large scale stress test pushed the network beyond its original performance targets by processing billions of transactions through off chain Lightning Tunnels before batching and settling them onchain. The achievement has sparked widespread discussion across the crypto industry, with supporters praising the network’s scalability while critics continue to debate whether offchain transactions should count toward blockchain throughput records.
Sui Tunnels Experiment Pushes Network to New Limits
The Sui Tunnels Experiment demonstrated an entirely new approach to handling massive transaction volumes. During the live event, participants generated approximately 2.3 billion transactions in just 20 minutes using Lightning Tunnels, an offchain batching system designed to maximize throughput before final settlement on the blockchain. According to Sui cofounder Adeniyi Abio, the experiment successfully exceeded every technical objective and established a new benchmark for blockchain scalability. The reported peak of 6 million TPS places the network ahead of previous public performance claims from competing blockchains, including Solana and the Internet Computer Protocol (ICP), during controlled stress testing environments.
Performance Claims Face Industry Debate
Despite the impressive numbers, the record has generated debate throughout the blockchain community. Critics argue that much of the transaction activity occurred offchain before settlement, making direct comparisons with fully on-chain TPS measurements difficult. Supporters counter that modern blockchain infrastructure increasingly relies on hybrid execution models that improve efficiency without sacrificing final settlement security. The experiment highlights how blockchain developers continue to explore innovative scaling technologies capable of supporting billions of future users while reducing congestion and maintaining lower transaction costs.
Ecosystem Growth Continues Beyond the Stress Test
Although the stress test reached extraordinary throughput, the network’s typical daily activity remains significantly lower, averaging roughly 45 TPS under normal operating conditions. Revenue also remains modest at around $1,000 per day despite the project’s estimated $7.4 billion valuation. Even so, the broader ecosystem continues to expand as decentralized finance activity gains momentum, with DeFi trading volumes surpassing $20 million. Developers continue building applications across the network, while investors closely watch whether growing adoption can translate into stronger onchain activity, higher protocol revenue, and long term ecosystem expansion.
