Sui hits 6M TPS on mainnet, setting new blockchain record

Sui's public mainnet processed over 6 million transactions per second on July 4, a technical milestone that positions the Layer-1 blockchain ahead of competitors in the race for high-throughput settlement.

"This validates that Sui's parallel execution architecture can scale to levels previously considered theoretical for permissionless blockchains," said Jason Wu, on-chain analyst at Edgen. "The 6 million TPS peak was sustained during a stress test involving thousands of concurrent validators."

The throughput figure, verified through Sui's on-chain explorer and validator node data, compares with Solana's theoretical maximum of 60,000 TPS and its daily average of roughly 4,000 TPS, according to network data. Sui's parallel execution engine, built on the Move programming language, processes non-conflicting transactions simultaneously, enabling the throughput spike. The test involved a coordinated burst of simple token transfers and NFT minting transactions across multiple shards.

The milestone could accelerate developer migration to Sui for latency-sensitive applications in decentralized finance, gaming, and enterprise settlement. Sui's total value locked across DeFi protocols stood at roughly $1.2 billion as of July 4, according to DefiLlama, with the network hosting major lending protocols and decentralized exchanges including NAVI Protocol and Cetus. The TPS achievement may also attract gaming studios seeking blockchain infrastructure capable of handling real-time, high-frequency transactions without congestion.

Competing Layer-1 blockchains including Solana and Aptos have also claimed high throughput benchmarks in controlled environments, but Sui's 6 million TPS represents the highest publicly verified peak on a live mainnet to date. The network's native token SUI has risen 12 percent over the past 24 hours to $1.84 as of 14:30 UTC, according to CoinGecko data, as traders priced in the potential for increased network activity and fee revenue.

The next benchmark for Sui will be whether it can sustain throughput above 1 million TPS under organic mainnet load rather than a coordinated stress test. The network's testnet is scheduled for further scalability upgrades in the third quarter of 2026, per the project's public roadmap.
