The Sonic blockchain confirmed transactions in just 720 milliseconds during its testnet. Finality means that once the blockchain records a transaction, it becomes permanent and cannot be reversed. Sonic is positioning itself as the fastest Ethereum Virtual Machine (EVM) chain globally, with an impressive finality time of 720 milliseconds.
This claim comes from the creator of the Fantom Network and CTO of Sonic Labs, Andre Cronje. In a post shared on Sept. 8, Cronje stated:
400ms responsiveness, ideal for real-time events. 720ms finality — and it’s final, no waiting for 30 more blocks.
Once a transaction is completed, most blockchains need multiple additional blocks to ensure it can’t be undone. Sonic speeds this up, achieving transaction finality in just over 700 milliseconds. The blockchain widely recognizes Cronje as a key figure in DeFi. He’s the founder of Yearn Finance and the Keep3r Network.
Sonic chain’s testnet shows record transaction finality
Even though the Sonic chain is currently in a testnet, where performance can be better than in real-world conditions, its transaction speed is still remarkable. Specifically, Cronje believes that if the blockchain maintains this speed after its mainnet launch, it could become the fastest blockchain for transaction finality.
Solana’s mainnet is currently the fastest blockchain network, with transactions being finalized in just 12.8 seconds, according to Chainspect. Moreover, Solana produces faster blocks, taking just 400 milliseconds, and typically requires 31 block confirmations to achieve finality. In contrast, the blockchain testnet reaches this final stage in just 420 milliseconds.
Sonic could become a popular choice for blockchain developers. According to Cronje, a big reason for this is that the network returns 90% of the transaction fees directly to the developers. Additionally, the Fantom Foundation backed Sonic’s growth by allocating $120 million worth of Fantom tokens in June to encourage developers to move their projects from Fantom to Sonic.
On May 23, the foundation revealed the launch of the blockchain Foundation and the chain. Fantom’s Sonic Foundation will handle Sonic’s governance, manage the network’s funds, build partnerships, and grow the ecosystem of decentralized applications.
