London, UK, September 2025 – Silent Data, a new Ethereum Layer 2 from Applied Blockchain, gives organizations a new way to run blockchain applications without exposing sensitive information. As the first privacy blockchain technology developed using the OP Stack, Silent Data brings programmable privacy to the Superchain ecosystem, unlocking blockchain’s benefits for regulated and data-sensitive users.

“Leveraging the OP Stack allows us to integrate into a robust and widely adopted Layer 2 ecosystem,” says Adi Ben-Ari, CEO and Founder of Applied Blockchain, the company behind Silent Data. “We’re excited to align with the Superchain’s mission and explore how Silent Data can support new privacy-first use cases alongside the Optimism Foundation.”

Silent Data joins a growing ecosystem of over 30 Layer 2 networks working to scale Ethereum – including major players like Base by Coinbase, OP Mainnet, Uniswap’s Unichain, Kraken’s Ink, Sony’s Soneium, and World Chain – and is the first to provide a powerful privacy wrapper tailored for real-world adoption. Its architecture aligns with the Superchain vision – championed by the Optimism Collective – of unifying the Ethereum experience across chains. By enabling sensitive workloads to run on-chain while preserving transparency and composability, Silent Data opens up the Superchain to new categories of applications.

"Privacy-preserving blockchain technologies will drive real-world adoption, particularly for organizations that operate in highly regulated industries with stringent data protection laws,” said Alim Khamisa, DeFi Partnerships at Optimism Foundation. “Onchain privacy mechanisms often serve dual purposes – safeguarding sensitive user data while giving enterprises the transaction confidentiality necessary for proprietary commercial activities. Silent Data introduces a powerful new privacy mechanism as an OP Stack chain. It's an exciting contribution that unlocks new enterprise use cases on the Superchain."

Silent Data stack can also be adopted by existing Superchain L2’s, and those seeking to deploy their own L2. Silent Data launched with an accompanying library of ready-made, privacy-enabled blueprint applications, and is being explored by a number of organizations including Tokeny, an Apex group company, and Archax in real world asset (RWA) tokenization, Shell in energy trading, and CRYOPDP, part of DHL Health Logistics.

Many businesses seek the benefits of blockchain – transparency, automation, and tokenization – but are blocked by privacy and compliance concerns. To overcome this, some turn to private blockchains to avoid exposing sensitive data like identities or transaction values. But this often leads to isolated systems that expose single point failures, higher attack surfaces, and potential censorship from a centralized operator.

Silent Data breaks that trade-off by combining the interoperability and verifiability of public chains with the control, confidentiality, and performance of private infrastructure. Sensitive data remains hardware-protected at all times: the Silent Data L2 blockchain runs within a Trusted Execution Environment (TEE), such that commercially sensitive data is never visible to the operator. Access is strictly governed by standard Solidity (EVM) smart contracts, allowing only authorised parties to view specific data, under specific conditions.
