Today, Applied Blockchain’s Silent Data — a new Ethereum Layer 2 network — became the first privacy-focused chain to join the Superchain, the Optimism-backed ecosystem of L2s, the company said Sept. 3. The move positions Silent Data as the OP Stack’s first privacy rollup inside a growing cross-chain environment.
Built on the OP Stack, Silent Data combines what Applied Blockchain calls “programmable privacy” with scalability and regulatory alignment. The stack is designed to let organizations run blockchain applications without exposing sensitive data, enabling on-chain workflows for industries that require confidentiality.
The Superchain already includes more than 30 Layer 2 networks — from Coinbase’s Base and Optimism Mainnet to Kraken’s Ink and Uniswap’s Unichain — and Silent Data brings a new privacy-focused option that uses a privacy wrapper to execute sensitive workloads while retaining composability and auditability.
Applied Blockchain launched a library of privacy-enabled applications and says the technology is being trialed across multiple sectors. Named partners and pilot users include Tokeny and Archax for real-world asset tokenization, Shell for energy trading, and CRYOPDP (a DHL Health Logistics unit) for healthcare and supply chain use cases.
Why this matters: a privacy-first L2 that integrates with the OP Stack could lower barriers for enterprise adoption by offering familiar tooling with added confidentiality. That said, there are trade-offs — privacy layers may attract regulatory scrutiny, complicate audits, and introduce integration challenges for DeFi composability and developer tooling.
