The emergence of Sonic and what it means for DeFi: Report

Fantom’s evolution into Sonic represents a significant upgrade to address scalability and performance limitations. Initially built on a DAG design, Fantom utilized the Ethereum Virtual Machine (EVM) and Ethereum-derived account storage. This led to challenges including bloated storage and slow transaction execution. To overcome these hurdles, the Fantom team developed Sonic, a completely independent blockchain network.

Sonic’s core innovation lies in its proprietary SonicVM execution engine. SonicVM dynamically translates EVM bytecode into a faster internal format, optimizing heavy computations and pre-analyzing contract code for enhanced efficiency. Crucially, SonicVM maintains full EVM compatibility, ensuring seamless operation of existing Fantom smart contracts.

Addressing Fantom’s storage bottlenecks, Sonic introduces SonicDB, a novel database design that separates the blockchain state into two databases: LiveDB for rapid access to the current state, and ArchiveDB for historical data storage. This separation dramatically reduces storage requirements for consensus nodes (up to 90%), minimizing hardware needs and synchronization times.

The Sonic mainnet utilizes a new native token, S, offering a 1:1 exchange for existing FTM tokens. Initially non-inflationary for six months post-launch (December 2024), a subsequent 6% minting rewards early adopters. A Gas Fee Monetization (FeeM) mechanism further incentivizes developers, routing up to 90% of transaction fees from participating applications to developers, with the remainder allocated to validators.

Andre Cronje, a key figure behind Fantom and Yearn.finance, is leading DeFi development on Sonic. His project, Flying Tulip, integrates trading, liquidity pools, and lending functionalities, employing a dynamic bonding curve similar to Curve v2. This design dynamically adjusts its curvature based on oracle-observed prices, concentrating liquidity around the current price for enhanced capital efficiency. Flying Tulip introduces faster equilibrium curve updates and narrower ranges, along with a novel dynamic loan-to-value model. The transition to Sonic signifies a substantial upgrade for Fantom, aiming to establish a more efficient and scalable platform for decentralized finance.
