Fantom Sonic offers unprecedented scalability and storage to developers, and a swift, streamlined experience for users.
With a new virtual machine, improved storage, and optimized consensus, Fantom Sonic offers unprecedented scalability and affordable storage to developers, and a swift, streamlined experience for users.
Sonic is the newest iteration of Fantom that uses innovative blockchain technology to scale the network to unprecedented heights.

The Fantom Virtual Machine (FVM) offers superior execution performance compared to the EVM by processing over 65x more transactions per second.
The FVM converts EVM bytecode seamlessly into a new virtual machine format and supports super instructions, optimized bundles of commonly occurring instruction patterns, to reduce execution time.
Sonic continues to use the Lachesis consensus mechanism, but it has vastly improved the transaction pool for collecting transactions of users.
The Carmen database storage uses flat storage as opposed to tree-like structures to simplify data retrieval and offer reductions in storage requirements, e.g. reducing archive node size from above 11 TB to below 1 TB.
Carmen supports live pruning, which allows validators to discard historical data that is no longer needed while remaining online to prevent operational disruptions.
Fantom Sonic is the name that covers the new Fantom technology stack. Essentially, it is the next iteration of the Fantom network, with no hard fork required for the upgrade. Existing smart contracts, services, and tools on Fantom Opera should be fully compatible with mainnet Fantom Sonic.
Fantom Sonic is in its testnet stage at the moment and will roll out as a mainnet to replace Fantom Opera in spring 2024. Currently, Sonic offers two different testnets: the closed testnet aims to showcase the maximum theoretical limits of Sonic, whereas the builders testnet is interactive, allowing any user and developer to experience Sonic directly or deploy dApps.
The FVM (Fantom Virtual Machine) is just one component of Sonic and a substantial improvement over the previous Ethereum Virtual Machine implementation.
Yes. The FVM is fully compatible with the EVM and its programming languages (Solidity, Vyper, etc.), so smart contracts do not need to be changed.
Fantom 2.0 is Fantom Sonic. It is the name that has been used leading up to the announcement of Sonic.
Yes. Fantom Opera is the name of the technology stack that Sonic will replace.
The Fantom Sonic testnet environment consists of two separate testnets to demonstrate the upgrade before its mainnet release.
No. This means that existing smart contracts, services, and tools on Fantom Opera should be fully compatible with mainnet Fantom Sonic.
The team is planning on releasing binaries/executables that will enable others to run nodes in the future.
The exact timing is to be determined, but we anticipate deploying the mainnet in spring 2024.
