Silent Data developed by Applied Blockchain becomes first privacy-focused layer 2 to Join Ethereum’s Superchain. The project is one of over 30 layer-2 networks working to scale Ethereum.

Silent Data, a new Ethereum layer-2 network developed by London-based firm Applied Blockchain, has become the first privacy-focused chain built on the OP Stack to join Ethereum’s Superchain. The Superchain is an ecosystem of more than 30 OP Stack-based layer-2s, including networks such as Coinbase’s Base, OP Mainnet, Kraken’s Ink, Sony’s Soneium, Uniswap’s Unichain, and World Chain, all aimed at scaling Ethereum while remaining interoperable. Silent Data’s addition makes privacy-preserving computation a first-class feature within this ecosystem, differentiating it from other Superchain members that primarily focus on throughput and user scale rather than confidential data processing. Silent Data is designed to let organizations run blockchain applications without exposing sensitive information, using a “privacy wrapper” that sits over standard EVM logic so developers can write privacy rules directly in Solidity. It leverages Trusted Execution Environments (TEEs) to provide fully programmable, Turing-complete privacy, enabling use cases such as private stablecoin payments, tokenized real‑world assets, supply chain workflows, and healthcare data sharing while retaining auditability and compliance controls. The network is already being tested or explored by firms including Tokeny, Archax, Shell, and CRYOPDP (DHL Health Logistics), positioning it as an infrastructure layer targeted at regulated and data‑sensitive users who want to tap into Ethereum and the Superchain without making commercially or legally sensitive data public.
