Ethereum is putting privacy back at the center of its roadmap.
This November, during the Devcon conference in Argentina, the Ethereum Foundation will announce Kohaku, a new wallet framework designed to allow users to transact without exposing unnecessary personal information or transaction details.
This project was introduced by Foundation Developers on October 9th. Nicolas ConsignyHe said Kohaku’s demo and software development kit (SDK) will be available for public testing at Devcon. This wallet is built as both a browser extension and a reference implementation for developers who want to integrate privacy primitives directly into their applications.
These tools are designed to allow users to complete transactions while revealing only the minimum amount of information necessary for each party involved.
He explained:
“Kohaku aims to enable each party to a transaction to know only what is directly necessary for that transaction and to absolutely minimize the risks required to execute the transaction.”
Kohaku is just one part of the Ethereum Foundation’s larger effort to make privacy a “first-class property” on the blockchain.
On October 8, the Foundation announced its new Privacy Cluster, a team of 47 engineers, researchers, and cryptographers dedicated to integrating privacy at every layer of the Ethereum stack.
According to the foundation, this effort is necessary for blockchain’s growth because “privacy is normal and necessary to ensure that this infrastructure remains easy to use, reliable, and consistent with human freedom.”
As a result, the new cluster will work closely with the Privacy and Scaling Explorations (PSE) initiative to improve protocol-level confidentiality for everything from private payments to decentralized identity solutions.
Ethereum is focused on privacy
The Privacy Cluster’s work covers several key areas that form the basis of Ethereum’s evolving privacy architecture.
On the research front, the PSE team is pioneering advanced cryptographic techniques such as zero-knowledge proofs, which can increase scalability and confidentiality without compromising security.
Insights from this research will be passed directly to the protocol layer, allowing developers to integrate these breakthroughs into Ethereum’s core infrastructure to ensure privacy features are built into the network design rather than being added as external patches.
Moving to the application layer, projects like semaphores, MACI, and stealth addresses demonstrate how privacy can power real-world use cases, from decentralized governance to everyday payments.
Privacy at scale is not just a technical challenge. It’s a regulatory thing.
To this end, the Foundation has established an Institutional Privacy Task Force to explore how privacy protection technologies can coexist with compliance requirements. The group plans to issue guidelines mapping privacy tools to real-world frameworks used by businesses, financial institutions, and auditors.
This approach reflects Vitalik Buterin’s long-held view that privacy should be a “human right built into protocol design” rather than an optional feature for advanced users.
The market seems to be validating the privacy thesis.
According to data cited by Crypto Rand, privacy-focused tokens have outperformed the broader cryptocurrency market by 65.3% over the past 30 days, reflecting growing interest in tools that provide transaction-level confidentiality.
Ethereum’s new focus on privacy signals a philosophical shift from reactive compliance to proactive design. As artificial intelligence expands data extraction and governments increase on-chain surveillance, Ethereum is betting that a privacy-preserving base layer will be essential for mainstream adoption.
If Kohaku and the privacy cluster are successful, “private by default” could become a protocol standard rather than just a slogan in Ethereum’s next iteration.
