What Is Soneium? The Basics Explained
Soneium is a Layer 2 blockchain built on Ethereum, designed to enhance scalability, reduce transaction costs, and make Web3 technologies more user-friendly. For beginners, let’s break this down:
- Layer 2 (L2) Blockchain: Ethereum, the second-largest blockchain by market cap, is known for its security and decentralization but struggles with high fees and slow transaction speeds. Layer 2 solutions like Soneium process transactions off the main Ethereum chain (Layer 1) to improve speed and affordability, while still leveraging Ethereum’s security. Learn more about Ethereum in this guide.
- Built on Optimism’s OP Stack: Soneium uses the OP Stack, a framework developed by Optimism, to create a scalable and interoperable blockchain. It’s part of Optimism’s Superchain ecosystem, which connects multiple L2 networks for seamless interaction. Create a token on Optimism here.
- Sony’s Vision: Soneium’s mission is to “connect blockchain technology (Web3) with everyday internet services (Web2),” making decentralized applications (dApps) accessible to a broader audience. Sony aims to integrate Soneium into its diverse businesses, including gaming, entertainment, finance, and electronics.
In simpler terms, Soneium is Sony’s attempt to bring the benefits of blockchain—such as transparency, security, and decentralization—into the products and services you already use, without the complexity typically associated with Web3.
The Story Behind Soneium: Sony’s Journey into Web3
Sony’s interest in blockchain isn’t entirely new. The company began exploring Web3 as early as 2018, focusing on managing intellectual property like music and video content. In 2021, Sony Music partnered with Theta Labs to enhance fan engagement through NFTs, and Sony also invested in blockchain companies like Animoca Brands to strengthen its presence in the metaverse and Web3 space. Read more about the future of the metaverse.
The real turning point came in 2023 when Sony invested in Startale Labs, a Singapore-based Web3 company that founded Astar Network, a multi-chain blockchain platform. This partnership laid the groundwork for Soneium. In August 2024, Sony Block Solutions Labs (a joint venture between Sony and Startale) announced Soneium, launching its Minato testnet to allow developers to experiment with the platform. By January 2025, Soneium’s mainnet went live, marking a significant milestone in Sony’s blockchain journey.
During its testnet phase, Soneium saw impressive engagement: over 14 million accounts were created, and the platform processed more than 47 million transactions in just four months. This early success highlights the potential for Soneium to become a major player in the blockchain space.
How Does Soneium Work? A Technical Overview for Beginners
If you’re new to blockchain, the technical details might seem overwhelming, but let’s simplify how Soneium operates:
- Layer 2 Scaling with Optimistic Rollups: Soneium uses optimistic rollup technology, a method that processes transactions off-chain (on Layer 2) and then submits them in batches to Ethereum’s mainnet (Layer 1). This reduces congestion on Ethereum, lowers gas fees, and speeds up transactions while maintaining security. Compare this to Proof of Work vs. Proof of Stake.
- OP Stack and Superchain Integration: The OP Stack is a modular framework that makes it easy to build scalable L2 blockchains. By joining Optimism’s Superchain ecosystem, Soneium ensures interoperability with other L2 networks, meaning assets and data can move seamlessly between Soneium, Ethereum, and other Optimism-based chains.
- EVM Compatibility: Soneium is compatible with the Ethereum Virtual Machine (EVM), which means developers can use existing Ethereum tools and smart contracts with minimal changes. This lowers the barrier for developers to build on Soneium. Learn about ERC-20 tokens.
- Minato Testnet and Mainnet: The Minato testnet, launched in August 2024, allowed developers to test dApps in a safe environment. The mainnet, launched in January 2025, opened Soneium to the public, enabling real-world applications and transactions. Create a token on Soneium’s testnet.
For users, this means Soneium offers fast, low-cost transactions—perfect for applications like gaming, NFTs, and DeFi—while still benefiting from Ethereum’s robust security.
