Vitalik Releases Ethereum Privacy Roadmap, Is Ethereum Set to Take Off? Positive Outlook for the Privacy Sector

Core Content of Ethereum Privacy Upgrade Plan:

1. Payment Privacy: Integrate tools like Railgun and Privacy Pools into existing wallets, default support for 'shielded balance' sending functionality, simplifying user privacy transaction operations.

2. In-App Anonymity: Promote 'independent address per application' model, sever public associations of cross-application behavior, requiring users to accept increased operational complexity.

3. RPC Privacy Protection: Short-term use of TEE technology to protect RPC node data, long-term shift to cryptographic privacy retrieval (PIR) technology, and support for multi-node connections and mixing networks to reduce metadata leakage.

4. Protocol Optimization:

- Implement FOCIL and EIP-7701 to eliminate reliance of privacy protocols on relay nodes;

- Develop transaction proof aggregation protocol to reduce gas costs for privacy transactions;

- Default enable 'self-transfer privacy' feature to support multi-address systems.

5. Key Management: Develop privacy-protecting key vault wallets, supporting one-click key updates across L1/L2 without exposing asset associations.

Targeted Outcomes:

- Default privacy for most transfers;

- Public behavior within single applications, anonymous association of cross-application behavior;

- Defense against privacy attacks from on-chain observers and RPC nodes.
