**Ethereum Co-founder Vitalik Buterin Unveils Layer-1 Privacy Roadmap**
Ethereum co-founder Vitalik Buterin has proposed a simplified roadmap to enhance privacy on the Ethereum blockchain’s Layer-1 network. In an April 11 blog post, Buterin introduced a strategy aimed at improving user confidentiality without major changes to the network’s core infrastructure.
The proposal focuses on four key areas: making on-chain payments private, partially obscuring user activities in decentralized applications, concealing read-access data, and anonymizing network communications. Buterin emphasized that these upgrades could make private transactions the norm, although individual decentralized application (dApp) activities might still be visible. This approach would help protect users from observers and infrastructure-level threats, such as compromised RPC nodes.
Key elements of Buterin’s proposal include integrating privacy tools like Railgun directly into Ethereum wallets, allowing users to manage shielded balances without third-party apps. He suggested a “send from shielded balance” option as a default feature to enhance user experience. Additionally, he recommended using separate addresses for each dApp to limit traceability, despite potential user experience trade-offs.
Buterin also outlined technical improvements, such as implementing TEE-based RPC privacy as a short-term solution and transitioning to private information retrieval (PIR) in the future. Other recommendations include connecting each dApp to separate RPC nodes, advancing proof aggregation protocols, and supporting privacy-enhanced keystore wallets.
