Cross-company action needs two trust planes:

Control plane: identity, mandates, policy, status, revocation and receipts.

Data plane: provenance, DPPs, BOMs, SBOMs, validation, freshness and system state.

Authority and evidence must work together.

.@VitalikButerin just made a bold declaration: ETHEREUM HAS SOLVED THE BLOCKCHAIN TRILEMMA

He credits a new combination of technical upgrades that are working together to push the network’s scaling limit – without sacrificing decentralization or security.

Today, we’re exploring where Ethereum is headed next. 👇

~~ Article by @JackInabinet ~~

🔍 Ethereum’s Scaling Future

All networks make tradeoffs between decentralization, security, and scalability.

While peer-to-peer file sharing platform BitTorrent is highly decentralized and very scalable, it has no single source of truth that forms network consensus, providing weak security guarantees.

Although Bitcoin achieves strong decentralization and security guarantees, the network has an extremely slow throughput of approximately 7 transactions per second.

And while the Solana network delivers Bitcoin-like security at much faster speeds, the network’s hefty hardware requirements restrict participation to commercial-quality node operators, limiting decentralization.

The blockchain trilemma constrained the development of a balanced blockchain that simultaneously optimizes for decentralization, security, and scalability in each of these examples.

Yet, Vitalik Buterin believes Ethereum can achieve where others have failed using zkEVMs and PeerDAS.

🔒 What are zkEVMs?

Zero-Knowledge Ethereum Virtual Machines (zkEVMs) are a type of scaling solution that executes Ethereum transactions offchain and proves their correctness back onchain using cryptographic zero-knowledge proofs.

Instead of individually submitting transactions to the Ethereum L1, zkEVMs bundle thousands of transactions together in a proof, which accounts for the results of transactions while circumventing the need for blockchain computation. This design increases scalability by using offchain execution, while preserving Ethereum-grade security via onchain proof verification.

Vitalik characterizes contemporary zkEVMs as “alpha stage,” claiming they enjoy production-quality performance, but require safety work. He expects their full benefits to emerge over the next 4 years, with the first opportunities to run zkEVM nodes occurring sometime in the new year.

📡 What is PeerDAS?

Peer-to-Peer Data Availability Sampling (PeerDAS) is Ethereum’s latest leap in data scaling. It was adopted to mainnet on December 3, 2025, and served as the headline improvement of Ethereum’s recent Fusaka upgrade.

Rollups need to publish transaction data to Ethereum so the network can independently verify state transitions, and PeerDAS dramatically reduces the cost of making this data available by allowing nodes to sample small pieces of data from peers, rather than downloading entire data blobs.

PeerDAS (live today on mainnet) allowed Ethereum to increase the dedicated “blob” storage space for data availability with no changes to the hardware requirements for nodes that want to validate the Ethereum L1.

🧭 Where to Next?

Over the next four years, Vitalik believes that Ethereum can become the first network to fully conquer the blockchain trilemma. Such a breakthrough is not anticipated to be the outcome of a single sudden achievement; rather it is expected to be the gradual result of sustained progress over time.

Ethereum has already expanded data availability through PeerDAS, and while developers expect initial zkEVM node experiments to begin this year, Buterin doesn’t anticipate zkEVMs will become a dominant method of block validation until later this decade.

Although execution risk remains, should Vitalik’s scaling vision materialize, Ethereum could very well redefine what’s possible for decentralized systems, offering a model where security, decentralization, and scalability reinforce one another instead of competing.

“Ethereum was not created to make finance efficient or apps convenient. It was created to set people free”

This was an important - and controversial - line from the Trustless Manifesto ( https://t.co/QAvZfiNxpe ), and it is worth revisiting it and better understanding what it means.

“efficient” and “convenient” have the connotation of improving the average case, in situations where it’s already pretty good. Efficiency is about telling the world's best engineers to put their souls into reducing latency from 473 ms to 368ms, or increasing yields from 4.5% APY to 5.3% APY. Convenience is about people making one click instead of three, and reducing signup times from 1 min to 20 sec.

These things can be good to do. But we must do them under the understanding that we will never be as good at this game as the Silicon Valley corporate players. And so the primary underlying game that Ethereum plays must be a different game. What is the game? Resilience.

Resilience is the game where it’s not about 4.5% APY vs 5.3% APY - rather, it’s about minimizing the chance that you get -100% APY.

Resilience is the game where if you become politically unpopular and get deplatformed, or if a the developers of your application go bankrupt or disappear, or if Cloudflare goes down, or if an internet cyberwar breaks out, your 2000ms latency continues to be 2000ms.

Resilience is the game where anyone, anywhere in the world will be able to access the network and be a first-class participant.

Resilience is sovereignty. Not sovereignty in the sense of lobbying to become a UN member state and shaking hands at Davos in two weeks, but sovereignty in the sense that people talk about "digital sovereignty" or "food sovereignty" - aggressively reducing your vulnerabilities to external dependencies that can be taken away from you on a whim. This is the sense in which the world computer can be sovereign, and in doing so make its users also sovereign.

This baseline is what enables interdependence as equals, and not as vassals of corporate overlords thousands of kilometers away.

This is the game that Ethereum is suited to win, and it delivers a type of value that, in our increasingly unstable world, a lot of people are going to need.

The fundamental DNA of web2 consumer tech is not suited to resilience. The fundamental DNA of _finance_ often spends considerable effort on resilience, but it is a very partial form of resilience, good at solving for some types of risks but not others.

Blockspace is abundant. Decentralized, permissionless and resilient blockspace is not. Ethereum must first and foremost be decentralized, permissionless and resilient block space - and then make that abundant.
