Highlight of Community Posts About Fantom Sonic

After announcing Fantom Sonic and releasing its testnet environment, we were thrilled to watch the community engage with the brand-new network capable of handling beyond 2,000 transactions per second with a one-second finality.

We compiled some of the best posts on X from the Fantom community about Sonic below.


Rumor has it that Fantom will hand out participation trophies to wallets that can’t keep up with Sonic.


For innovation to be groundbreaking, it needs to make everything before it feel antiquated.


We definitely like this take more than the original. (Sorry, Vitalik.)


If Crypto_Dan believes in Sonic enough to forget his physics lessons, so do we.


In the true spirit of decentralization, Fantom is international. (Grazie mille!)


In case you missed it, interacting with Sonic just got easier than ever.


A thread for the ages!


Did someone say monumental shift!?


No words needed. The launch of Sonic will be nothing short of thrilling.


You heard it here first, everyone! Faster than any has ever been.

Frequently asked questions

Expandable Text Box
What is Fantom Sonic, and what does it encapsulate?
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.

The launch of Sonic comprises three main components that scale Fantom to new heights:

● A new virtual machine, the Fantom Virtual Machine (FVM), which increases our transaction throughput significantly while maintaining ultra-short finality.
● A new database storage, Carmen, which reduces storage requirements by up to 90%, providing greater cost efficiency for validators and accelerating the Foundation’s ability to deploy archive nodes from weeks to approximately 36 hours.
● An optimized Lachesis consensus mechanism, which brings a vastly improved transaction pool.

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 open testnet is interactive, allowing any user to experience Sonic directly.
What about the FVM?
The FVM (Fantom Virtual Machine) is just one component of Sonic and a substantial improvement over the previous Ethereum Virtual Machine implementation.

Most importantly, this new virtual machine allows Fantom validators to execute smart contracts more efficiently.
Does the FVM still run Solidity smart contracts?
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.
What is Fantom 2.0?
Fantom 2.0 is Fantom Sonic. It is the name that has been used leading up to the announcement of Sonic.
Will it replace Fantom Opera?
Yes. Fantom Opera is the name of the technology stack that Sonic will replace.
What is the difference between the closed and open testnet?
The Fantom Sonic testnet environment consists of two separate testnets to demonstrate the upgrade before its mainnet release.

The closed testnet is viewable only and aims to showcase the maximum theoretical limits of Sonic, whereas the open testnet is interactive, allowing any user to experience Sonic directly.
Will there be a hard fork?
No. This means that existing smart contracts, services, and tools on Fantom Opera should be fully compatible with mainnet Fantom Sonic.

However, there may be even more significant performance gains with further testing that may require a hard fork in the future, but the current plan is not to hard fork Fantom Opera.
Will the community be able to run nodes for the Sonic testnet?
The team is planning on releasing binaries/executables that will enable others to run nodes in the future.
When does the Sonic mainnet release?
The exact timing is to be determined, but we anticipate deploying the mainnet in spring 2024.
When is the Sonic testnet opening to the public?
On Tuesday, October 24, 2023.
