Solana Hits 100,000 TPS in Mainnet Stress Test

Solana has become the first major blockchain to register over 100,000 transactions per second (TPS) on its mainnet, according to Mert Mumtaz, co-founder of the Solana development platform Helius. The network recorded a peak TPS of 107,540 during a recent stress test, with a single block containing 43,016 successful transactions.

However, the majority of these transactions were no-operation (“noop”) program calls—lightweight instructions that do not involve state changes or real token transfers. These noop transactions are used primarily to test network capacity rather than simulate real-world blockchain activity.

What the TPS milestone really means

While the figure showcases Solana’s upper bound throughput, actual performance metrics paint a more conservative picture. According to Solscan, Solana’s average throughput is around 3,700 TPS, though nearly two-thirds of that consists of validator vote transactions. Excluding consensus-related activity and other non-economic transactions, Solana throughput has hovered between 1,000 and 1,400 transactions per second in the last 30 days, according to data from Chainspect.

Despite the caveats, developers argue that practical applications like token transfers and oracle updates could theoretically reach 80,000 to 100,000 TPS under optimized conditions. This positions Solana as a high-performance chain capable of supporting demanding applications such as real-time gaming, AI integrations, and decentralized order books.

Solana’s scaling roadmap

The recent benchmark adds weight to Solana’s scaling narrative, especially when contrasted with Layer-1 competitors like Ethereum and Avalanche, which rely on rollups and modular architectures to improve throughput. Solana, in contrast, emphasizes single-chain performance and validator efficiency.

The network has also seen growth in decentralized finance (DeFi), with total value locked (TVL) reaching $10.7 billion, nearing its all-time high. 

Future developments like the Firedancer validator client by Jump Crypto, which has shown over 1.2 million TPS in test environments, promise further scaling potential. Solana’s roadmap also includes architectural changes like separating execution from consensus and implementing localized fee markets to reduce congestion.

While the 100,000 TPS mark is not reflective of current user-facing capabilities, it serves as a strong indicator of Solana’s technical potential and growing relevance in the broader blockchain ecosystem.
