TON Takes Block Finality Lead with 0.6 Second Confirmation Time
The Open Network (TON) has taken the lead in block finality among Layer-1 chains, according to Telegram founder Pavel Durov. In a post on his Telegram channel, Durov shared data from an April 2026 study that ranked TON's performance against top 30 Layer-1 networks.
The study showed that TON finalized blocks in roughly 0.6 seconds, the fastest time among Layer-1 chains. Avalanche (AVAX) followed closely at about one second, with BNB Chain (BNB) at 1.125 seconds.
Sui (SUI), Hedera (HBAR), XRP Ledger (XRP), and Stellar (XLM) trailed behind, with block finalization times ranging from two to five seconds. Solana (SOL) required roughly 32 slots to reach finalized commitment, while Ethereum (ETH) needed two epochs, or about 12.8 minutes.
BTC was at the bottom of the list, requiring a six-confirmation convention that took about an hour, and Cardano (ADA) was slightly better off with its Ouroboros design taking roughly one day.
