According to Cointelegraph, the Sonic chain has achieved a transaction finality of 720 milliseconds (ms) during its testnet phase, marking a significant milestone in blockchain development. In blockchain, finality is the assurance that a transaction is irreversible once it is added to a block on the blockchain ledger. Sonic claims to be the world’s fastest Ethereum Virtual Machine (EVM) chain, with a 'true' 720-ms finality, according to Andre Cronje, the creator of the Fantom Network and the chief technology officer of Sonic Labs.
Cronje highlighted the achievement in a Sept. 8 X post, stating, '400ms responsiveness (perfect for synchronous events). 720ms finality (true, not probabilistic - no
