Sony Group's joint project with Singapore's Startale Labs will launch a new layer 2 network

Sony Block Solutions Labs, a joint project between Sony Group and Singapore-based Startale Labs, said on Friday that it will launch a new two-layer network called Soneium on the Ethereum blockchain.
Soneium, which is expected to go live on the testnet in the next few days, will leverage Optimism Rollup technology, which allows users to transact on the Ethereum network at a lower cost. It will be built using the Optimism blockchain ecosystem's OP Stack, a customizable toolkit that allows developers to create their own networks using Optimism's technology and connect to other networks in the ecosystem via a "hyperchain".
