Finalized plans now live here: https://privreads.ethereum.foundation/roadmap

Q1 Recap

Goals:

• Unlocking privacy of reads for all Ethereum blockchain data in different contexts of consumptions (wallets, frontends, dApps) by building and productionizing scalable obliviousness primitives particularly PIR
• Unlocking network-level privacy for all Ethereum RPC traffic from wallets by adapting Arti in embedded browser [extension] contexts serving frontends and browser wallets particularly; and creating an access-layer abstraction such that a diverse set of anonymization routing solutions (eg 0 1 2 3 4 5 ) can be plugged into
• Driving integrations and adoption of PIR systems and anonymized routing we built at the edges and the infra
• Incubating, coordinating and supporting builders of Ethereum-native, local-first, privacy-defaulted, and bot-resistant applications
• Communicating privacy to the public: making it easier to understand R&D and use the solutions we and others build through visual and written content
• Accelerate privacy with microgrants and PAPs and external collaborations

1Q 26

• Build:

  • 2-4 PIR schemes tailored for Ethereum state and history tailored optimized for different usage profiles and contexts (wallets, frontends, tax software, dApps)
  • EIP7864-enabled (UBT) provably L1-equivalent EL node
  • Arti Tor client embedded in-browser

• Coordinate more integrations of anonymized routing of RPC calls in wallets and SDKs thereof

• Communicate: implement privacy adoption dashboard showcasing affordances and adoption of anonymized routing in wallets[sdk] and RPC providers. Kick start a privacy spotlight series

• Accelerate with (a) micro-grants: lean, incremental tasks (b) external collabs by providing problem definitions and technical advice

• Continue supporting EcoDev on privacy as they interface with ecosystem projects

• Deliverables in Q1:

  • [x] 2-4 implementations of PIR schemes for L1 data
    • Plinko, RMS24, VIA, (new) LeanPIR
  • [ ] Fully sync’d provably MPT-equivalent UBT EL node
    • Geth: blocked by inefficient binary-mpt conversion, improving
    • Ethrex: kicked off late Q1
    • Assigned member (takamichi) left EF, replacing in Q2
  • [x] Arti Tor client embedded in browser.
    • Ready for integrations
  • [x] Spotlight series 1x
    • Communication was re-oriented towards technical comms [1] [2] and docs

  Stretch:

  • [ ] Arti integrated in Kohaku and a wallet SDK which allows other wallets that depend on the SDK to plug into it more easily
    • Rolled into Q2, adapting Arti for the browser took all of Q1
  • [ ] A PIR integration in Kohaku and/or Helios
    • The sharded approach meant pushing integrations till later, Q3, to flesh out sharded harness first. Add-hoc demo of LeanPIR particularly may be done in Q2.

2Q 26

• [x] Finalize April 2026
