The Ethereum Foundation (EF) has spawned a new for-profit startup, EthSystems, which will focus on bringing blockchain privacy technology to banks and other financial institutions. The company was founded by former members of the EF's Institutional Privacy Task Force, a group that had been researching and developing privacy-preserving solutions for institutional use cases.
What is EthSystems?
EthSystems is building a suite of privacy infrastructure tools that leverage the Ethereum blockchain to enable banks to transact with confidentiality. The startup's technology allows institutions to execute smart contracts and transfer assets while keeping transaction details private from the public ledger. This is achieved through a combination of zero-knowledge proofs (ZKPs), secure multi-party computation (sMPC), and other cryptographic techniques.
The company will offer its solutions as a white-label service, meaning banks can integrate EthSystems' privacy layer into their existing systems without overhauling their entire IT infrastructure. This approach is intended to lower the barrier to entry for traditional financial institutions that are wary of the transparency of public blockchains.
Background: The Institutional Privacy Task Force
The Institutional Privacy Task Force was established within the Ethereum Foundation in 2024, with the goal of exploring how privacy features could be built into the Ethereum protocol to meet the needs of regulated entities like banks. The task force worked on several proposals, including modifications to the Ethereum Virtual Machine (EVM) and the development of new precompiled contracts for privacy operations.
EthSystems is the commercialization of that work. The founders have stated that they believe the private sector is better suited to bring these technologies to market at scale, and that a for-profit entity can more effectively navigate the complex regulatory landscape of banking.
The Bigger Picture: Ethereum Foundation Restructuring
The launch of EthSystems comes amid one of the most significant organizational shakeups in the Ethereum Foundation's history. Over the past year, the EF has restructured its approach to protocol development, spinning out several independent entities to focus on specific areas. In addition to EthSystems, the foundation has created EthLabs, which concentrates on core protocol research and development, and Ethereum Institutional, which handles education and outreach to enterprise clients.
This decentralization of the EF's functions is seen by many in the Ethereum community as a positive step, potentially increasing agility and reducing the risk of a single point of failure. However, some have raised concerns about the potential for conflicts of interest, as the spinouts may compete for the same talent and resources.
Privacy Technology and Institutional Adoption
Privacy is a critical issue for banks exploring blockchain technology. While public ledgers offer transparency and immutability, they also expose transaction data that banks are legally obligated to keep confidential. Regulatory frameworks such as GDPR and Basel III impose strict rules on data sharing and disclosure.
Several other companies are also working on blockchain privacy for institutions, including Aztec, which focuses on private smart contracts, and Soda, which provides a privacy layer for Ethereum. EthSystems differentiates itself by targeting the banking sector specifically and by building on the core Ethereum protocol rather than on a separate layer.
The startup has already engaged with several European banks in pilot programs, according to sources familiar with the matter. The pilots involve using EthSystems technology for cross-border payments, trade finance, and digital asset custody, where privacy is essential to comply with know-your-customer (KYC) and anti-money laundering (AML) regulations.
Technical Architecture of EthSystems
EthSystems architecture consists of three main components: a privacy oracle, a confidentiality module, and an audit layer. The privacy oracle retrieves data from external sources and proves its validity without revealing the data itself. The confidentiality module handles encryption and decryption of transaction payloads, ensuring that only authorized parties can see the details. The audit layer gives regulators the ability to view transactions under certain conditions, such as when a court order is issued.
By design, the system ensures that no single entity can unilaterally access private data. Instead, access is controlled through a multi-signature scheme involving the bank, its counterparties, and a regulatory authority. This aligns with the principle of “privacy for the user, transparency for the regulator” that is often cited in central bank digital currency (CBDC) discussions.
Competitive Landscape
The market for blockchain privacy solutions for institutions is growing rapidly. Competitors include QANplatform, which offers quantum-resistant privacy, and Partisia Blockchain, which uses secure multi-party computation. However, EthSystems benefits from its close association with the Ethereum Foundation, which lends it credibility and access to the largest developer ecosystem in the blockchain space.
Additionally, the startup is positioning itself as a compliance-first solution. By embedding regulatory reporting and audit trails into its product from the beginning, EthSystems aims to win the trust of risk-averse banking executives who have been burned by the association of crypto with illicit activity.
Implications for the Ethereum Ecosystem
If EthSystems succeeds in onboarding major banks, it could drive significant demand for Ethereum blockspace. Each private transaction will still result in an on-chain proof verifying the validity of the off-chain data, meaning the bank will pay gas fees. This could create a new revenue stream for Ethereum validators and potentially increase the network’s overall usage.
Furthermore, the technology developed by EthSystems could eventually be incorporated into the base Ethereum protocol. The EF has a history of adopting innovations from its spinouts. For example, features like account abstraction and EIP-1559 were heavily inspired by projects that started outside the core team.
There are also synergies with Ethereum’s roadmap toward sharding and danksharding. Privacy solutions like those from EthSystems can benefit from higher throughput and lower fees, making them more practical for high-volume banking applications.
Recent News Around Ethereum and Privacy
The launch of EthSystems comes at a time when privacy is a hot topic in the crypto space. Just this week, Zcash announced a new node capable of processing 50,000 transactions per second, targeting Visa-scale privacy. Meanwhile, regulators in France ordered ISPs to block the prediction market Polymarket, citing gambling laws. These events highlight the increasing regulatory scrutiny on transparency and privacy.
On the ETF front, Bitcoin ETFs saw renewed inflows, though analysts described them as “peanuts” compared to recent outflows. Bitcoin price flatlined near $64,000 as oil prices hit a one-month high. Institutional interest in crypto remains strong, but price action is muted amid macroeconomic uncertainty.
In other news, Michael Saylor, Bitcoin’s biggest advocate, criticized a new plan to clean up the blockchain, calling it a “bad idea.” The debate over blockchain governance continues to rage, with some calling for more active management of the ledger to address environmental concerns and others advocating for the purity of immutability.
Key Takeaways for Banks
For banks considering Ethereum as a settlement layer, EthSystems offers a path to compliance. The startup’s technology allows institutions to participate in decentralized finance (DeFi) and tokenized asset markets without exposing sensitive client information. This could unlock trillions of dollars in assets that have been waiting on the sidelines due to privacy concerns.
Several major banks, including JPMorgan, HSBC, and Santander, have already experiment with privacy-blockchain solutions. EthSystems hopes to become the default provider by offering an open-source core with commercial support, similar to what Red Hat does for Linux.
It remains to be seen whether the for-profit spinout model will be successful. The Ethereum Foundation itself has been criticized for its slow pace of innovation and cumbersome governance. By spinning out EthSystems as a nimble startup, the foundation is betting that entrepreneurial energy will outperform committee-driven development.
