Ethereum's Strawmap Prioritizes Privacy, Post-Quantum Safety, and Native Rollups

Ethereum’s updated “Strawmap” reorders the project’s priorities, putting privacy and post‑quantum safety higher on the list as cryptography and AI reshape long‑term development, co‑founder Vitalik Buterin said in an Aug. 10 post on X. Buterin overlaid the network’s 2023 roadmap with the current Strawmap to show what’s moved up, what’s been pushed back, and what’s newly appeared. While there’s still substantial overlap between the two plans, several notable shifts stand out: - Up‑prioritized: quantum safety and related work to future‑proof signatures and verification. - New additions (absent from the 2023 roadmap): native privacy, post‑quantum scaling, simpler specifications to enable formal verification, markets for blob and gas capacity, native rollups, and broader exploration of EVM replacements or modifications. - Deprioritized or changed: verifiable delay functions (VDFs) and some EVM improvement proposals. - Technical design changes: Verkle trees gave way to a unified binary tree and later a PBT design; the old state‑expiry idea broadened into a proposal for new state types. What’s new — and why it matters Native privacy Privacy is one of the clearest new priorities. Buterin lists several mechanisms now under active exploration: keyed nonces, recent‑root proofs, parts of FOCIL, “lean privacy pools,” and wormholes. - Keyed nonces would make it harder for observers to link a user’s transactions. - Recent‑root techniques aim to let private apps verify recent blockchain state without revealing a full history. - FOCIL (a block‑builder inclusion primitive) is intended to make transaction inclusion more resistant to censorship by builders. These additions build on Buterin’s three‑step privacy plan unveiled in May, which combines account abstraction, FOCIL, keyed nonces, and wallet/access‑layer changes to cut down metadata leaks and strengthen censorship resistance. Post‑quantum scaling Quantum resistance has moved toward the front of the roadmap. Ethereum’s current signature and crypto suites could be threatened by future quantum computers, and replacing them without exploding signature sizes or verification costs is a nontrivial scaling problem. Potential approaches under consideration include LeanSPHINCS signatures, signature aggregation, and “zkzk frames.” Researchers have also demonstrated account‑level post‑quantum protection at an estimated cost of about $0.07 per account, suggesting wallet‑level mitigation could begin before any protocol‑wide upgrade. Native rollups and specialized scaling Native rollups — verification primitives integrated into the Ethereum base protocol rather than being purely layer‑2 systems — are now on the table. Today rollups run off‑chain and post proofs or data to Ethereum; a native rollup model would let the base layer standardize part of that verification, lowering custom infrastructure needs for each rollup. The concept could simplify rollup maintenance but raises open questions about which functions should be native, how multiple VMs would be supported, and whether protocol‑level verification itself could add complexity. Buterin also signals a strategic shift away from one‑size‑fits‑all scaling: instead of forcing all activity through a single general mechanism, developers may build highly scalable but narrower systems optimized for common high‑volume tasks like token transfers, DEX trades, and privacy applications. Blob and gas futures Strawmap introduces the idea of markets for future blob and gas capacity. Such mechanisms could let users or L2s lock in access to data or execution capacity ahead of time, reducing cost uncertainty during demand spikes. Formal verification, STARKs and AI Ethereum’s updated roadmap places extra emphasis on simplifying protocol specifications to make large‑scale formal verification practical. Formal verification produces mathematical proofs that software adheres to its intended rules — a historically difficult task for complex, multi‑client blockchains. Buterin argues that AI advances are making large‑scale verification more achievable. Recursive STARKs (where one proof verifies another) are a central piece of that vision: the same proof technology could potentially verify work across execution, consensus, and data layers, but doing so would heighten the importance of formal verification and independent auditing. EVM and instruction‑set possibilities Longer term, the roadmap contemplates exposing a different low‑level instruction set beneath the EVM to support zkzk frames — options include leanISA or even RISC‑V. One model would keep the EVM as an intermediate representation for existing apps while a simpler underlying instruction set serves as the execution substrate. Buterin stresses this area is very early stage and not yet part of a finalized plan. What this means for users and markets Buterin frames the Strawmap as a coordination document covering proposed upgrades through 2029, not a fixed schedule. Each major idea — native rollups, post‑quantum signatures, alternative instruction sets — still requires research, testing, client implementation, and governance before any activation. The post announced no imminent software release or hard fork. The market reaction was muted: ETH traded near $1,875 at the time of Buterin’s post, down roughly 2.6% over 24 hours amid broader crypto weakness. Bottom line Scaling remains central to Ethereum’s roadmap, but the balance is shifting. Privacy, quantum resistance, and verifiable protocol design now carry more weight in shaping how the network could evolve through the end of the decade. The Strawmap lays out many possible directions — each technically plausible but still subject to months or years of research and community agreement.
