Vitalik Buterin Unveils Plan to Elevate Privacy on Ethereum

• Ethereum Plans to Make Privacy Default with Protected Balance
• Vitalik suggests unique address for each decentralized app
• Privacy with PIR and mixnets reduces data exposure in RPC

Vitalik Buterin, one of the founders of Ethereum, shared recently issued a detailed proposal to improve the privacy of the network’s users. Published on its blog on April 10, the document suggests a lightweight and practical approach, without the need for structural changes to the Ethereum protocol consensus.

The central idea involves incorporating privacy features directly into digital wallets, with tools such as Privacy Pools and solutions already used by projects such as Railway Private DeFi Wallet. Buterin advocates that users should be able to activate a “protected balance” by default, with the possibility of sending values ​​directly from this balance, without needing to install a specific wallet for this purpose.

De agreement According to the developer, the goal is to make private transactions more common, making this the default option whenever possible. He also proposed using different addresses for each decentralized application (DApp), which would reduce traceability between different activities carried out by the same user. Although he acknowledges the loss of convenience, he considers this a practical solution to preserve privacy in decentralized environments.

Another point addressed in the plan is the need for transactions sent to the wallet itself to also remain confidential, strengthening individual protection. It also suggests integrating privacy layers using security modules such as TEE (Trusted Execution Environment) in communications via RPC (Remote Procedure Call). According to Buterin, this solution is temporary until technologies such as PIR (Private Information Retrieval) become more efficient.

The proposal also recommends that wallets connect to multiple RPC nodes, preferably through mixnets, with separate servers for each DApp. This reduces data exposure when transferring information between the user and the blockchain.

Finally, Buterin suggests technical advances in privacy-focused protocols such as Railway and Tornado Cash, as well as enabling the use of shared proofs in transactions and the development of wallets that keep data protected even in complex interactions. The goal, he says, is to create a secure environment even in the face of potentially malicious RPC node operators.
