The development of scalability solutions on Ethereum has taken various forms, ranging from layer 2 blockchains to sidechains with different levels of decentralization. Large corporations have begun exploring the potential of blockchain technology, seeking to integrate their applications and services within a more efficient and accessible framework.

Soneium is Sony’s initiative, a layer 2 blockchain that is part of Optimism’s Superchain, designed to facilitate Web3 adoption. Unlike other corporate blockchain projects, Soneium has been designed from the outset with a technical approach that ensures a high level of interoperability and scalability at all times.

What is Soneium?

Soneium is a layer 2 blockchain developed by Sony, designed to integrate Web3 technologies into everyday applications. Its purpose is to provide an optimized infrastructure for creators and developers working in sectors such as gaming, entertainment, finance, and music. The platform was conceived to minimize the gap between Web2 and Web3 through accessible tools that facilitate the adoption of smart contracts, NFTs, and other decentralized solutions, avoiding common technical challenges.

Unlike other large corporations’ initiatives in the blockchain industry, Soneium is a comprehensive effort to establish a scalable infrastructure within the Ethereum ecosystem. Its integration with Optimistic Rollups and inclusion in Optimism’s Superchain align with its focus on efficiency and ecosystem compatibility. Additionally, Sony has established various strategic partnerships with firms such as Astar Network, Chainlink, Alchemy, and Circle to ensure that Soneium has a solid technical foundation from the start.

How Does Soneium Work?

Soneium operates as a scaling solution on Ethereum using Optimistic Rollup technology, allowing it to process transactions more efficiently by bundling them before submitting them to the main network. This model reduces congestion and gas fees without compromising network security, as transactions can be verified and challenged on Ethereum if malicious activity is detected.

The protocol is based on Optimism’s OP Stack, a modular set of tools that simplifies the creation of layer 2 networks and enables interoperability with other similar solutions. This means that Soneium not only benefits from improvements implemented within the Optimism ecosystem but also contributes to the expansion of the Superchain, a structure designed to connect multiple OP Stack-based blockchains.

Architecture and Design

Data Availability Layer: Ensures that all transaction information is published on Ethereum to maintain transparency and prevent censorship.
Sequencing Layer: Responsible for ordering transactions and batching them before submitting them to the main network, although this process is currently centralized.
Derivation Layer: Executes transactions on layer 2 to maintain consistency with Ethereum.
Execution Layer: Directly processes transactions and updates the state of the network.
Fraud Proof Layer: Finally, the fraud proof layer allows users to submit claims if they detect manipulation attempts in validated transactions.

The combination of these elements enables Soneium to function as an efficient and scalable network without compromising Ethereum’s decentralization. Additionally, by being part of Optimism’s Superchain, the network inherits interoperability mechanisms that facilitate communication with other OP Stack-based scaling solutions.

Fee System

Soneium adopts Ethereum’s fee model, meaning transaction costs are determined by activity on the main network. As part of its cost structure, transactions on the network include a layer one (L1) fee, which covers the cost of publishing data on Ethereum, and a layer two (L2) fee, which covers execution within Soneium. The L1 fee fluctuates based on network congestion, allowing users to optimize their costs by sending transactions during periods of lower activity.

Minato

To promote development within its ecosystem, Sony has launched the Minato testnet, a testing environment where developers can experiment with the network before the mainnet deployment. Minato allows users to connect their wallets and test applications without incurring real costs, offering tools such as a block explorer developed in collaboration with Blockscout. This explorer provides metrics on network activity, transactions, verified contracts, and gas costs, facilitating project monitoring and optimization during experimental phases.

Soneium Spark

Sony has launched the Soneium Spark program, an initiative designed to drive application development within its ecosystem. This program offers funding of up to $100,000 for teams presenting innovative projects based on Soneium’s blockchain. Selected participants gain access to specialized mentorship, advanced technical infrastructure, and connections with strategic partners who can accelerate the adoption of their products in the market.

Conclusion

Soneium is Sony’s strategic move to integrate into the blockchain ecosystem with a scaling solution focused on creators and developers. Its adoption of Optimistic Rollups and integration into Optimism’s Superchain provide a solid technical foundation, while its partnerships with established industry firms enhance its interoperability and expansion potential.

Sony is focused on building an attractive ecosystem for developers, offering tools, funding, and technical support to facilitate decentralized application development. Although it has not yet been defined whether it will have its own token, its integration with Ethereum allows it to operate without requiring a native asset at this initial stage.

With a structure designed to optimize costs and improve user experience without compromising security, Soneium has the potential to establish itself as a viable alternative within the layer 2 solutions ecosystem on Ethereum. Its evolution will depend on adoption by developers and projects looking to leverage its capabilities, as well as future updates that expand its functionalities and integration with other networks
