Solana Sets Record With 107,664 Transactions Per Second in Single Block

Solana recorded 107,540 transactions per second on mainnet during a stress test using mostly no-operation program calls, marking the first claimed instance of a major blockchain surpassing 100,000 TPS. Helius co-founder Mert Mumtaz credited the milestone to developer “dr cavey phd” for executing the high-load test, which occurred within block 360650523 containing 43,016 successful and 50 failed transactions. While the test affirmed Solana’s theoretical capacity for up to 100,000 TPS, current real-world use averages around 900–1,050 TPS for user transactions, with most network activity driven by memecoin trading. The event coincides with validator preparations to vote on the SIMD-0326 “Alpenglow” protocol upgrade, which would replace TowerBFT with a new voting protocol targeting 100–150 millisecond finality and eliminate on-chain vote transactions. SOL trades near $180, down 38% from its all-time high, as open interest in derivatives nears $12 billion and the SEC extends review for Solana ETF proposals.
