Solana's real-world transaction processing power has surpassed 2,500 transactions per second (TPS), outperforming most other blockchain networks. This achievement is significant because it showcases Solana's ability to handle high volumes of user-initiated transactions.
The network's architecture, which combines Proof-of-History (PoH) with Tower BFT consensus, allows for parallel processing of transactions, resulting in sustained levels around 3,000 TPS. Historical peaks have exceeded 4,500 TPS during busy days, while total TPS can frequently spike above 6,000.
Transaction costs remain low, typically below $0.01 per transaction. In contrast, Ethereum's base layer processes only 15-30 TPS, relying on Layer-2 rollups to scale beyond that. Solana's validator consolidation trend is a risk factor worth monitoring, as the network relies on a shrinking pool of node operators.
