Fastest Blockchains by Settlement Finality

Comparing networks by time-to-finality reveals which protocols are truly capable of supporting near-instant institutional and retail financial transactions.

The top 3

  1. Solana (Leader): Following the Alpenglow upgrade, Solana leads the pack with deterministic finality reaching 100–150 milliseconds. Solana
  2. Avalanche / Sui / Aptos (Contenders): These high-throughput networks consistently achieve sub-second to low-second finality, challenging Solana's performance dominance.
  3. Ethereum (Security Baseline): While Layer 2 rollups provide fast 'soft' confirmations, the base layer requires roughly 12–13 minutes for finality, emphasizing security over raw speed. Ethereum
