TechFlow reports that the Fantom Foundation has launched the Fantom Sonic testnet, featuring a new virtual machine FVM, an improved database storage system Carmen, and an optimized Lachesis consensus mechanism. The upgrade requires no hard fork, and existing smart contracts, services, and tools on Fantom Opera are fully compatible with Fantom Sonic, which is expected to achieve over 2,000 TPS.
Users and developers are now allowed to access the Fantom Sonic testnet environment, which consists of two separate testnets. The closed testnet aims to demonstrate its maximum theoretical limits, while the open testnet is interactive and allows any user to directly experience the network. The mainnet launch is planned for spring 2024.
