Vitalik Buterin Unveils Customized Ethereum Layer-1 Privacy Roadmap
Ethereum co-founder Vitalik Buterin has proposed a detailed plan to improve user privacy on the blockchain without changing its core structure. The roadmap was shared on April 11 through the Ethereum Magicians forum. This comes as one of the latest direct propositions from the Ethereum innovator to enhance the overall functionality of the chain.
Vitalik Buterin’s Roadmap for Ethereum Privacy
As detailed on the Ethereum Magicians forum, Vitalik Buterin disclosed that the roadmap is intended to make everyday Ethereum ETH $1 562 24h volatility: 2.4% Market cap: $188.58 B Vol. 24h: $20.15 B use more private. In the update, he said privacy on the network remains weak and needs urgent attention.
My own current privacy roadmap (much lighter on L1 changes, but also more limited in its consequences): https://t.co/gBtRAC4Ou7
Highly encourage people to read both! https://t.co/vNw0ubNpEd

He mentioned that the plan will focus on four major areas. They include private onchain payments, limited anonymity within decentralized applications, private data reads, and network-level protections.
Currently, Ethereum’s public design allows anyone to trace the activity of a known address. As he pointed out, a single wallet can reveal a user’s full transaction history, the application they use, and who they interact with. Buterin stressed that while this openness supports trust and security, it exposes too much personal data.
However, the Ethereum co-founder recommends that wallets like MetaMask and Rabby adopt built-in privacy tools such as Railgun and Privacy Pools to fix this. According to him, these can give users a default shielded balance and private transfer options.
Similarly, a key part of the roadmap is using different addresses for each app rather than relying on a single one across all activities. Vitalik Buterin admits this comes with some discomfort but is the most effective way to unlink user actions across various platforms.
He added that transferring Ethereum and other tokens between a user’s wallets should also be private by default, which supports the one-address-per-app design.
Still, Buterin’s roadmap is structured to avoid making changes to Ethereum’s underlying protocol. Instead, he wants wallets and developers to adopt these features as part of the normal user experience.
Calls for Immediate Action on Ethereum Privacy
As outlined in the plan, Buterin also discussed ways users can protect their data from exposure on the network. He suggested that wallets rotate between multiple RPC nodes and route requests through mixnets, privacy tools that obscure sender and recipient metadata, much like a VPN.
He suggested starting with Trusted Execution Environments (TEEs) for short-term cryptographic privacy. Afterward, there may be a shift to a Private Information Retrieval (PIR) for stronger protection.
To reduce user costs, Buterin wants to apply proof aggregation, a method where several transactions share a single onchain proof. This helps maintain privacy without becoming too expensive for regular users.
He further encouraged the adoption of new standards like FOCIL (Fork-Choice Enforced Inclusion Lists) and EIP-7701. These innovations enable privacy protocols to operate without relying on centralized relays.
Vitalik Buterin urged developers and wallet creators to act now instead of waiting for major protocol changes. Ethereum’s next upgrade, Pectra, will launch on May 7 and introduce native account abstraction.
As noted earlier by Coinspeaker, the Pectra upgrade recently reached finality on the Holesky testnet after overcoming earlier disruptions. Still, the Ethereum co-founder emphasized that the privacy roadmap does not rely on it.
