Optimism has outlined a 10-year plan to phase out ECDSA-based accounts in favor of post-quantum smart contract accounts on its network. This transition aims to prepare for the potential risks posed by future quantum computing advancements, ensuring secure key management through account abstraction.

The roadmap outlines practical steps to enhance privacy for Ethereum users with minimal consensus changes, focusing on on-chain payment privacy, anonymization of application activity, and secure RPC interactions. Key proposals include integrating privacy tools into wallets, adopting one address per application, and improving RPC privacy through advanced technologies like TEE and PIR. Ultimately, the goal is to create a landscape where private transactions are the default and user activities across applications remain unlinked.

The Ethereum Foundation's Privacy Stewards of Ethereum has released a comprehensive roadmap aimed at enhancing end-to-end privacy on the blockchain. Key focus areas include private writes, reads, and proving, with the goal of ensuring that private onchain actions are affordable and compliant.
