The Sonic chain (formerly Fantom) has demonstrated a record transaction finality of 720 milliseconds during its testnet phase.
The Sonic chain (formerly Fantom) has demonstrated a record transaction finality of 720 milliseconds during its testnet phase. Andre Cronje, the lead developer of Fantom Network and chief technology officer of Sonic Labs, announced that Sonic's finality is "true, not probabilistic," eliminating the need for multiple block confirmations typically required by other blockchains.
Cronje's statement highlights two key metrics: a 400-millisecond responsiveness, which he describes as "perfect for synchronous events," and the 720-millisecond finality. In the context of blockchain technology, finality refers to the point at which a transaction becomes irreversible after being added to the blockchain ledger.
While most blockchain networks require several additional blocks to ensure transaction irreversibility, Sonic claims to accomplish this in just over 700 milliseconds However, these impressive figures were achieved in a testnet environment, which can sometimes yield better performance than real-world conditions.
Currently, the Solana network holds the title for the fastest mainnet, with a transaction finality of 12.8 seconds. While Solana boasts 400-millisecond block production times, it typically requires 31 block confirmations to reach true finality. However, if Sonic can maintain similar speeds after its mainnet launch, it could potentially become the fastest blockchain network in terms of transaction finality.
The Fantom Foundation, which supports Sonic's development, has announced in June that $120 million in token allocation will be allocated to developers to migrate their projects from Fantom to Sonic. Furthermore, Cronje revealed that up to 90% of the network's generated transaction fees would be paid back to developers, creating a powerful incentive for building on the Sonic blockchain.
