Hedera uses the Hashgraph consensus algorithm, which is based on a directed
acyclic graph (DAG). This algorithm provides several advantages:

`High Throughput`: The network can process thousands of transactions per second.
`Fairness`: Transactions are timestamped, ensuring fair ordering.
`Security`: It achieves asynchronous Byzantine Fault Tolerance (aBFT), the highest level of security for a consensus algorithm.

Sonic, originally launched as Fantom in June 2018 by the Fantom Foundation
and now rebranded, is a high-performance public blockchain network. It
leverages a unique consensus mechanism called Lachesis and supports its
native cryptocurrency, FTM. Sonic is designed to power decentralized
applications (dApps), smart contracts, and fast transactions, using the
Ethereum Virtual Machine (EVM) and Solidity for development.
</ul>
</div>
</div>

Sonic emphasizes rapid transaction processing, low costs, and scalability,
making it an attractive choice for both developers and enterprises. Unlike
traditional blockchain systems, Sonic’s Lachesis consensus delivers near-instant
finality and high throughput without sacrificing decentralization.

## Mainnet and testnet

SettleMint supports the **Sonic Mainnet** and the **Sonic Testnet**.

The Mainnet is the primary public Sonic network, where real-value transactions
take place. Each transaction incurs a fee, payable in FTM, the native
cryptocurrency. The Testnet, conversely, is a development environment for
testing and experimentation. Testnet FTM has no real-world value, allowing
developers to experiment freely without financial risk.

You can view the Testnet as a sandbox for prototyping and the Mainnet as the
live production network—akin to staging versus production environments in
software development.

## Consensus mechanism

Sonic utilizes the **Lachesis** consensus algorithm, an asynchronous Byzantine
Fault Tolerant (aBFT) protocol built on a directed acyclic graph (DAG)
structure. This approach offers several key benefits:

- `High Throughput`: Sonic can handle thousands of transactions per second.
- `Near-Instant Finality`: Transactions are confirmed in seconds, ensuring quick
settlement.
- `Security`: The aBFT design provides robust protection against malicious
actors.

In Lachesis, nodes process transactions independently and share updates
asynchronously through a gossip protocol. This allows the network to reach
consensus rapidly and efficiently, maintaining decentralization and resilience.
Validators stake FTM to participate, with penalties for misbehavior, ensuring
network integrity while keeping energy use minimal compared to Proof of Work
systems.

[official Sonic website](https://www.soniclabs.com/).

Soneium was launched in early 2025 by a team focused on advancing blockchain
interoperability and scalability. It introduces its native cryptocurrency, SON,
designed to power its ecosystem. Soneium operates as a layer 2 solution built
atop Ethereum, emphasizing high throughput, low-cost transactions, and seamless
cross-chain connectivity. It leverages advanced rollup technology to process
transactions off-chain, delivering faster speeds and reduced fees compared to
the Ethereum mainnet.

</ul>

</div>
</div>

# The basics

Soneium is fully compatible with the Ethereum Virtual Machine (EVM), allowing
developers to port their Ethereum-based dapps effortlessly. Beyond scalability,
Soneium prioritizes decentralization and user empowerment. The network is
secured by a distributed set of validators and governed through a decentralized
autonomous organization (DAO), ensuring no single party holds control over its
operations.

## Mainnet and testnet

SettleMint supports the **Soneium Mainnet** and the **Soneium Testnet**.

The Mainnet serves as Soneium’s primary public blockchain, where real-value
transactions occur, requiring the SON token for fees. The Testnet, on the other
hand, is a sandbox environment for developers to test and experiment without
financial risk, using valueless test tokens.

You can think of the Testnet as a sandbox for developers and the Mainnet as the
official production network. This setup is similar to the concept of production
versus staging servers in software development.

## Consensus mechanism

Soneium employs a hybrid consensus model combining **optimistic rollups** with a
**coordinator node**. Optimistic rollups assume transaction validity by default,
processing them off-chain for efficiency, while enabling challenges if fraud is
detected. The coordinator node batches transactions and submits them to the
network, though it remains untrusted—any validator can dispute invalid batches.

This design ensures Soneium is scalable, secure, and decentralized. However, it
may involve a withdrawal delay (typically seven days) and relies on a
centralized coordinator for transaction ordering, a trade-off for its
performance gains.
