Solana has achieved a groundbreaking milestone by becoming the first major blockchain to process over 100,000 transactions per second on its mainnet during a weekend stress test. The network briefly peaked at 107,540 TPS on August 17, marking a significant achievement in blockchain scalability and reigniting discussions about the network’s production readiness.
The record-breaking performance was orchestrated by a Solana engineer known as Cavey, who conducted the experiment using a personal validator node dubbed “Cavey Cool.” The test involved flooding the network with lightweight transactions to push the system to its theoretical limits, demonstrating the blockchain’s underlying infrastructure capabilities.
The milestone was first reported by Mert Mumtaz, co-founder of Solana developer tooling firm Helius, who shared that a single Solana block recorded 43,016 successful transactions and 50 failed ones during the peak performance period. However, the majority of these transactions were “no-operation” or “noop” program calls rather than meaningful token transfers or complex smart contract interactions.

These noop transactions are essentially lightweight instructions that perform minimal computation but satisfy Solana’s requirement that every transaction must include at least one instruction. While they effectively stress-test network capacity, they don’t directly reflect everyday payment activity or the complex operations typically seen in decentralized finance applications.
Despite the artificial nature of the test, Mumtaz emphasized that developers could “deduce that you can also theoretically do about 80-100k tps in transfers, oracle updates, and similar operations.” This suggests that Solana’s infrastructure could potentially handle similar throughput levels for real-world use cases under optimal conditions.
The achievement stands in stark contrast to Solana’s typical daily throughput, which hovers around 1,050 to 3,700 TPS according to network monitoring tools like Solscan. Approximately two-thirds of these transactions consist of validator voting activities rather than user-initiated operations, highlighting the difference between theoretical capacity and practical usage.
Technical Achievement and Network Capacity
The 100K TPS milestone represents more than just a number—it demonstrates the potential of Solana’s unique architecture to handle massive transaction volumes. The network’s ability to process such high throughput, even in a controlled environment, showcases the effectiveness of its consensus mechanism and parallel processing capabilities.
Current real-world transaction patterns on Solana show a network heavily dominated by memecoin trading activity, with platforms like Pump.fun accounting for 62% of the total value locked on the network. This activity profile differs significantly from the noop transactions used in the stress test, but provides insights into actual network utilization.
The technical specifications of the test reveal important details about Solana’s infrastructure limits. Each noop transaction consumed only one compute unit, representing the minimal computational load possible on the network. This efficient resource utilization allowed the validator to process the maximum number of transactions within a single block.
Solana’s block structure and timing mechanisms played crucial roles in achieving this throughput. The network’s 400-millisecond block times and parallel transaction processing architecture enabled the rapid succession of transactions that resulted in the record-breaking TPS figure.
Solana’s Scaling Journey
This milestone comes as part of Solana’s broader scaling initiatives, which have consistently pushed the boundaries of blockchain performance. The network has maintained its position as one of the fastest public blockchains, though it continues to operate under a “beta” label that some community members believe should be removed following this achievement.
The Firedancer validator client, developed by Jump Crypto and written in C and C++, has already demonstrated even more impressive performance on testnets, achieving over 1.2 million TPS in controlled environments. However, this client has not yet been deployed on mainnet, leaving Solana’s current infrastructure as the benchmark for actual performance.
Upcoming network upgrades, including SIMD-0266 governance voting mechanisms and continued development of the Firedancer client, could potentially enable sustained high-throughput performance in production environments. These improvements represent the next phase of Solana’s evolution toward enterprise-grade blockchain infrastructure.
The stress test results contribute to ongoing debates about blockchain scalability trilemmas and whether networks can maintain high performance while preserving decentralization and security. Solana’s achievement suggests that significant throughput improvements are possible within existing architectural frameworks.
Market Implications and Future Outlook
The timing of this achievement coincides with renewed interest in Solana’s ecosystem, as the network’s DeFi total value locked has climbed to $10.7 billion, approaching its January all-time high. The SOL token has been trading around $187, reflecting growing confidence in the network’s technical capabilities and ecosystem development.
Network activity metrics show sustained engagement across various application categories, from decentralized exchanges to NFT marketplaces. The ability to handle extreme transaction volumes could attract enterprise applications and high-frequency trading platforms that require guaranteed throughput levels.
Developer interest in building on Solana has remained strong throughout 2025, with the network’s tooling ecosystem continuing to mature. The stress test results provide concrete evidence of the network’s scalability potential, which could influence project migration decisions and new development initiatives.

The 100K TPS achievement positions Solana as a leading contender in the blockchain scalability race, potentially impacting institutional adoption and competitive positioning against other high-performance networks. While the test conditions were artificial, the demonstrated capability could translate into real-world advantages as blockchain applications continue scaling toward mainstream adoption levels.
- TPS (Transactions Per Second)
- A measure of blockchain network throughput indicating how many transactions can be processed within one second. Higher TPS generally indicates better scalability and user experience.
- Noop Transactions
- No-operation program calls that perform minimal computation but satisfy network requirements for transaction structure. They are commonly used for stress testing network capacity without meaningful state changes.
- Validator
- Network participants responsible for validating transactions and maintaining blockchain consensus. Validators play crucial roles in network security and performance.
- Mainnet
- The primary blockchain network where real transactions occur and actual value is transferred. Distinguished from testnets which are used for development and experimentation.
- DeFi (Decentralized Finance)
- Financial services built on blockchain networks that operate without traditional intermediaries. DeFi applications include lending, trading, and yield farming protocols.
