The basics

Soneium is a next-generation blockchain ecosystem designed to invoke emotion and empower creativity. It was founded by Sony Group Corporation, a global technology leader, and Startale, a Web3 innovator. Soneium stands as a versatile, general-purpose blockchain ready to serve diverse needs across all verticals and support users globally.

Soneium's L2 tech stack is based on the OP Stack technology from Optimism, as it plans to join the Superchain, a network of interconnected blockchains.

Soneium operates as a public Ethereum layer 2 solution that combines the security and decentralization of Ethereum with enhanced scalability and user-friendliness. It is integrated into the Superchain network, which uses Optimism's OP Stack technology to expand Ethereum's capacity. Soneium supports a wide range of applications, offering a comprehensive development environment with tools and resources tailored for both developers and users, all while aiming to make blockchain technology an integral part of everyday life.

Testnet​

Currently, Soneium is in its development phase and only offers a testnet. SettleMint supports the Soneium Minato testnet.

The Testnet is an instance of the blockchain used for testing and experimentation. The coins used in the Testnet have no real value, mitigating the risk of losing real funds. This allows developers and users to interact with the network, test applications, and experiment with features without financial risk.

You can consider the Testnet as a prototype environment, similar to a staging server in traditional software development.

Future Mainnet​

While Soneium does not have a mainnet at this time, it is anticipated that a mainnet will be launched in the future. The mainnet will be the primary public Soneium production blockchain where real-value transactions will occur. Each transaction on the future mainnet will likely require payment of a transaction fee, payable in the native coin SON.

Consensus mechanism​

Soneium employs an efficient consensus algorithm designed for high performance and security. While specific details about Soneium's consensus mechanism may not be publicly available, it likely shares some characteristics with other modern blockchain consensus protocols:

  1. High Throughput: The consensus mechanism is designed to process a large number of transactions quickly.
  2. Fast Finality: Transactions on the Soneium network are expected to be confirmed rapidly.
  3. Scalability: The system is built to handle increasing transaction volumes efficiently.
  4. Byzantine Fault Tolerance: The protocol aims to achieve consensus even if some nodes in the network act maliciously or fail.

The Soneium consensus algorithm is being developed to provide a robust foundation for decentralized applications, offering a balance of speed, security, and decentralization.
