TPS

Transactions Per Second — a measure of blockchain throughput. Bitcoin: ~7 TPS. Ethereum: ~15 TPS base layer, thousands via L2s. Solana: sustained 3,000-5,000 TPS with theoretical 65,000. TPS numbers should be read carefully — sustained TPS with real economic value differs from peak-theoretical or micro-transaction throughput. Comparison across chains often uses different metrics.
