Ethereum 2026: Moving Beyond Obsession with Mainstream Adoption—Vitalik Bets on Trustlessness
2026 is the year we decide that mainstream adoption at the expense of core values is not worth it. “Good enough” decentralization is not good enough. Users deserve something better than having to trust infrastructure providers to access a “trustless” network.

TechFlow Intro: Over the past decade, Ethereum has made carefully calculated compromises—trading trustlessness for convenience, sovereignty for user experience, and decentralization for mainstream adoption. But 2026 marks a turning point: the year Ethereum stops asking, “Is diluting ourselves for mainstream adoption worth it?” The answer is: no longer worth it. Stacy Muur details Vitalik’s vision: enabling full nodes to run easily again via ZK-EVM + block-level access lists; achieving verifiable RPCs via the Helios light client; enabling private payments with public UX via ORAM/PIR; moving beyond fragile seed phrases via social recovery; hosting unstoppable dapp UIs on IPFS; and achieving censorship-resistant block building via FOCIL. Re-centralization of the infrastructure layer must end.
Over the past decade, Ethereum has made carefully calculated compromises—trading trustlessness for convenience, sovereignty for user experience, and decentralization for mainstream adoption.
Every time you check your wallet balance, you’re trusting companies like Alchemy or Infura. Every time you use a dapp, your data leaks to servers you never chose.
But 2026 marks a turning point—the year Ethereum stops asking, “Is diluting ourselves for mainstream adoption worth it?” The answer is: no longer worth it.
Vision
- Full nodes easy to run again (ZK-EVM + block-level access lists)
- Verifiable RPC instead of blind trust (Helios light client)
- Private payments with public UX
- Wallets beyond fragile seed phrases (social recovery)
- Unstoppable dapp UIs (IPFS hosting)
- Censorship-resistant block building (FOCIL)
Problem: Infrastructure Re-Centralization
Even as the base layer remains decentralized, Ethereum’s infrastructure has grown increasingly centralized.
Nodes evolved from laptop-friendly to requiring >800 GB storage and 24-hour sync times. Dapps evolved from simple HTML pages into server-side monstrosities leaking your data everywhere. Wallets shifted from user-controlled RPCs to hardcoded providers tracking everything you do.
Most strikingly, today 80–90% of Ethereum blocks are produced by just two builders. This concentration places transaction inclusion under the control of a few entities who can censor anything they wish.
These aren’t bugs—they’re pragmatic choices made while scaling under proof-of-work constraints.
But the cost is real: trust assumptions quietly creep into the “trustless” system; single points of failure multiply; users lose genuine sovereignty. We decentralized the ledger—but re-centralized the access layer.
The 2026 Landscape
Full Nodes
Today’s reality: >800 GB storage, 24-hour sync, continuous uptime required—most users have given up.
Block-level access lists (BAL) fundamentally change this. Think of BAL as a directory per block, telling you in advance which state entries the block will touch. Your computer pre-fetches all required data in parallel before execution begins. Non-conflicting transactions run simultaneously on separate CPU cores. Analysis shows 60–80% of transactions have no overlap.
Combined with ZK proofs that verify blocks without re-executing all computations, sync time drops dramatically and storage becomes manageable. Running a node shifts from “infrastructure-company-only” back to “decent laptop territory.”
Helios: Verifiable RPC
Imagine this attack: You swap on Uniswap. Your malicious RPC shows you a fake price. You sign and accept fewer tokens than you should. The RPC executes a sandwich attack and pockets the profit. You never see it coming.
This hasn’t happened yet with major providers—but it’s technically possible. The problem? You’re trusting someone else to tell you the blockchain’s state.
Helios solves this in under 2 seconds. It’s a light client that tracks the validator “sync committee” (512 validators, ~27-hour cycle). If ≥2/3 sign a block header, it’s canonical. When checking your balance, Helios requests Merkle proofs from an untrusted RPC—and verifies them locally. The RPC can refuse to respond but cannot lie.
It runs anywhere: laptop, phone, browser extension. Use it as your MetaMask RPC—and every dapp instantly becomes trustless, with no other changes needed.
The tech exists today—open source and ready for integration.
ORAM/PIR: Private RPC Queries
Every RPC query leaks your behavior—who you’re watching, which protocols you’re using, when you’re using them.
ORAM (Oblivious RAM) uses tree structures to hide access patterns. The server sees you accessing data—but cannot tell which data. Signal Messenger uses this, cutting infrastructure costs 100× (from 500 servers down to 6).
PIR (Private Information Retrieval) lets you query a database without revealing what you’re looking for. You send an encrypted query; the server processes encrypted data; you decrypt the answer. Response size stays constant (~3 KB), regardless of database size.
Real implementations exist today:
- Oblivious Labs: private WBTC balance checker
- Private ENS resolution
- QuietRPC: private RPC explorer
The challenge is dynamic state: re-encoding 33 million elements takes 4–20 minutes. Solutions involve periodic snapshots with on-chain proofs. For most use cases (balance checks, voting eligibility), minutes of staleness are acceptable for privacy guarantees.
Social Recovery: Beyond Fragile Seed Phrases
Current wallets force impossible trade-offs:
- Lose your seed phrase → lose everything
- Seed phrase stolen → lose everything
- Cloud backup → sovereignty compromised by backdoors
Social recovery decentralizes trust. You hold a daily signing key plus “guardians” (friends, family, other devices). Recovery requires approval from 3 out of 5 guardians. A time lock (48–72 hours) prevents instant theft while allowing legitimate recovery.
Dropped your phone in a lake? Contact your guardians—they approve a new key, the time lock activates, and you regain access. If someone steals your key and tries this, you cancel during the time lock.
Security: An attacker must compromise ≥3/5 guardians simultaneously. You have days to respond. Each guardian holds only partial power. No tech company backdoors.
Wallets like Argent already support this. The 2026 goal: make it standard everywhere—with UX anyone can use.
Public UX for Private Payments
Privacy tools exist—but they’re painful: fragmented apps, poor UX, 3–5× higher gas costs, limited support. Almost nobody uses them.
2026 goal: Privacy = Public UX. Same wallet, same interface, comparable cost. Privacy becomes a checkbox—not a research project.
Technology: zkSNARKs (prove you have funds without revealing which ones), stealth addresses (one-time addresses per transaction), account abstraction integration.
FOCIL: Censorship-Resistant Privacy
If builders refuse to include private payments, those payments are worthless. With 80–90% of blocks coming from just two builders, censorship is trivial.
FOCIL (Fork Choice Imposed Inclusion List) makes censorship impossible:
Each slot, 16 validators are randomly selected to build an “inclusion list” (8 KB each) from the mempool. Block builders must include these transactions. Attesters vote only for blocks satisfying the inclusion list. Without votes, blocks cannot become canonical.
Why it works:
- Committee-based: Only one honest validator among 16 is needed
- Fork-choice enforced: Built into consensus—cannot be bypassed
- Same-slot: No latency
- Any position in block: Builders optimize MEV but cannot censor
For privacy: If one validator includes your private transaction, it must appear in the block. Builders cannot censor without financial loss.
IPFS-Hosted Dapps
When you visit Uniswap, you load the web app from their servers. If those servers go down, you’re locked out. If hacked—even for one second—malicious UI drains your wallet. Under load, they serve different UIs to different users.
IPFS solution: Host UIs via content addressing (identified by hash—not server). Anyone can host the content. Changing the UI changes its hash. ENS maps human-readable names to hashes.
Benefits: No single point of failure, impossible to hijack, censorship-resistant, verifiable.
Challenge: Updates mean new hashes. Solution: ENS records point to latest hashes, gradually decentralizing governance to DAOs.
Why This Matters
“In the world computer, there is no central overlord. No single point of failure. Only love.” — Vitalik
If Ethereum is just another platform requiring trusted intermediaries—why not use AWS?
The answer must be that Ethereum delivers something truly different: real ownership, genuine permissionlessness, practical censorship resistance, and authentic sovereignty.
But these matter only if they’re accessible. A system theoretically decentralized—but accessed through centralized bottlenecks—is just “decentralization theater.”
The stakes:
- Success: Ethereum becomes infrastructure for the open internet—users control their wealth/data, privacy is default
- Failure: Regulatory capture of the access layer, users abandon crypto for “honest” CBDCs, the cypherpunk dream dies
Conclusion
A pragmatic decade proved blockchains work. Now we prove they work—without sacrificing principles.
This won’t all ship in the next release. Building trustless systems with excellent UX takes time. Coordinating hundreds of developers takes even longer.
But the commitment is absolute. Every decision is evaluated against one criterion: Does it increase trustlessness and sovereignty?
2026 is when we decide mainstream adoption at the expense of core values is no longer worth it. “Good enough” decentralization isn’t good enough. Users deserve better than trusting infrastructure providers to access a “trustless” network.
The technical pieces are falling into place. Helios delivers verifiable RPC today. ORAM/PIR proves private queries work. Social recovery is live in production. FOCIL’s censorship resistance is specified. The path is clear.
Now let Ethereum build.
