Base is doing things the right way: an L2 on top of Ethereum, that uses its centralized features to provide stronger UX features, while still being tied into Ethereum's decentralized base layer for security.

Base does not have custody over your funds, they cannot steal funds or stop you from withdrawing funds (this is part of the L2beat stage 1 definition).

You can see Base's status as an L2 on l2beat: https://t.co/bBrvnbxSgD

I feel like many people have been confused by recent cynicism and think that things like L2beat are a weird sort of nerd-sharia compliance authority. This is NOT what is going on. The security that L2s provide, that L2beat measures, reflects concrete properties that protect you as a user from being rugged.

Here is an explanation of how, if an L2 shuts down, users are automatically able to withdraw funds even without that L2's involvement:

https://t.co/r3EF8lhTEl

Here is an example of how L2s prevent the operator from censoring transactions, that happened on Soneium earlier this year:

https://t.co/Pi0InKekbZ

This is what we mean when we say that L2s are non-custodial, they are extensions of ethereum, not glorified servers that happen to submit hashes. There are concrete pathways implemented in smart contract logic on Ethereum L1, that have been successfully used in the wild, that ensure that the L2 users' funds are ultimately controlled by L1, they cannot be stolen or blocked by the L2 operator.

Defi is a central part of the value that Ethereum provides. Financial empowerment is a central part of what it means to have agency and freedom in our current world. Finance is far from the only thing that Ethereum is good for, but it is an important thing. This post discusses how the Ethereum Foundation is approaching defi.

Defi today makes the world's best savings, risk management and wealth-building opportunities permissionlessly available worldwide. We need to build on that.

Ethereum's early defi era was great because it dared to dream and innovate and come up with totally new paradigms (eg. AMMs). Defi tomorrow will bring back that spirit. Don't just "make a better stablecoin", dig a layer deeper, and think about the underlying problem (risk management, hedging one's future expenses), and come up with an even better solution.

But also, as the EF, we are not interested in supporting "onchain finance" or even "defi" indiscriminately. We have a specific vision of what we want to see out of defi: permissionless, open-source, private, security-first global finance that maximizes people's control over their own assets, minimizes centralized chokepoints and trusted third parties, and democratizes risk management and wealth building (the two key goals of finance according to modern portfolio theory) as well as payments. We want protocols that pass the walkaway test: that keep working even if the original team suddenly disappears without warning (or even: becomes hostile / compromised without warning).

Bringing this vision to reality will inevitably take a lot of work. Defi is a complex toolchain, including various onchain components, user-side offchain components (ie. wallet, local agent...), other offchain components, etc.

The things that we care about include areas like:

* Improving security of defi through "traditional" means, eg. audits, standards, wallet-side safeguards
* Improving security of defi through "new" means, eg. AI-assisted formal verification, user-side agents as safeguards
* Oracle security and decentralization (there's A LOT of skeletons in the closet here, we as an ecosystem really need to point a big eye of sauron at it for a while)
* Privacy. Both privacy-preserving payments, and privacy of more complex use cases (eg. what does it mean to have a maximally privacy-preserving CDP? there are clearly benefits in reducing liquidation-sniping risk, but it requires hard tech to get there)
* Open source, and improving the licensing / forkability situation in defi

Ethereum is a permissionless protocol, and nothing stops people from deploying insecure protocols, protocols that enshrine ultimately unneeded centralized trust in the name of convenience, or dopamine-maximizing gambleslop. However, we *are* interested in working with anyone aligned to make permissionless, open-source, intermediary-minimizing and security and user-agency-maximizing defi ecosystem as strong as possible, so that it can be not just individuals and institutions' first choice in Ethereum, but also a globally compelling way to manage funds for anyone who needs its properties.

[LeGenDDD @setscrew_nub]

[vitalik.eth @VitalikButerin]

Now that ZKEVMs are at alpha stage (production-quality performance, remaining work is safety) and PeerDAS is live on mainnet, it's time to talk more about what this combination means for Ethereum.

These are not minor improvements; they are shifting Ethereum into being a fundamentally new and more powerful kind of decentralized network.

To see why, let's look at the two major types of p2p network so far:

BitTorrent (2000): huge total bandwidth, highly decentralized, no consensus

Bitcoin (2009): highly decentralized, consensus, but low bandwidth - because it’s not “distributed” in the sense of work being split up, it’s *replicated*

Now, Ethereum with PeerDAS (2025) and ZK-EVMs (expect small portions of the network using it in 2026), we get: decentralized, consensus and high bandwidth

The trilemma has been solved - not on paper, but with live running code, of which one half (data availability sampling) is *on mainnet today*, and the other half (ZK-EVMs) is *production-quality on performance today* - safety is what remains.

This was a 10-year journey (see the first commit of my original post on DAS here: https://t.co/Fa0jKFgObW , and ZK-EVM attempts started in ~2020), but it's finally here.

Over the next ~4 years, expect to see the full extent of this vision roll out:

* In 2026, large non-ZKEVM-dependent gas limit increases due to BALs and ePBS, and we'll see the first opportunities to run a ZKEVM node
* In 2026-28, gas repricings, changes to state structure, exec payload going into blobs, and other adjustments to make higher gas limits safe
* In 2027-30, large further gas limit increases, as ZKEVM becomes the primary way to validate blocks on the network

A third piece of this is distributed block building.

A long-term ideal holy grail is to get to a future where the full block is *never* constituted in one single place. This will not be necessary for a long time, but IMO it is worth striving for us at least have the capability to do that.

Even before that point, we want the meaningful authority in block building to be as distributed as possible. This can be done either in-protocol (eg. maybe we figure out how to expand FOCIL to make it a primary channel for txs), or out-of-protocol with distributed builder marketplaces. This reduces risk of centralized interference with real-time transaction inclusion, AND it creates a better environment for geographical fairness.

Onward.

[vitalik.eth @VitalikButerin]

Over the past year, many people I talk to have expressed worry about two topics:

* Various aspects of the way the world is going: government control and surveillance, wars, corporate power and surveillance, tech enshittification / corposlop, social media becoming a memetic warzone, AI and how it interplays with all of the above...
* The brute reality that Ethereum seems to be absent from meaningfully improving the lives of people subject to these things, even on the dimensions we deeply care about (eg. freedom, privacy, security of digital life, community self-organization)

It is easy to bond over the first, to commiserate over the fact that beauty and good in the world seems to be receding and darkness advancing, and uncaring powerful people in high places are making this happen. But ultimately, it is easy to acknowledge problems, the hard thing is actually shining a light forward, coming up with a concrete plan that makes the situation better.

The second has been weighing heavily on my mind, and on the minds of many of our brightest and most idealistic Ethereans. I personally never felt any upset or fear when political memecoins went on Solana, or various zero-sum gambling applications go on whatever 250 millisecond block chain strikes their fancy. But it *does* weigh on me that, through all of the various low-grade online memetic wars, international overreaches of corporate and government power, and other issues of the last few years, Ethereum has been playing a very limited role in making people's lives better. What *are* the liberating technologies? Starlink is the most obvious one. Locally-running open-weights LLMs are another. Signal is a third. Community Notes is a fourth, tackling the problem from a different angle.

One response is to say "stop dreaming big, we need to hunker down and accept that finance is our lane and laser-focus on that". But this is ultimately hollow. Financial freedom and security is critical. But it seems obvious that, while adding a perfectly free and open and sovereign and debasement-proof financial system would fix some things, but it would leave the bulk of our deep worries about the world unaddressed. It's okay for individuals to laser-focus on finance, but we need to be part of some greater whole that has things to say about the other problems too.

At the same time, Ethereum cannot fix the world. Ethereum is the "wrong-shaped tool" for that: beyond a certain point, "fixing the world" implies a form of power projection that is more like a centralized political entity than like a decentralized technology community.

So what can we do? I think that we in Ethereum should conceptualize ourselves as being part of an ecosystem building "sanctuary technologies": free open-source technologies that let people live, work, talk to each other, manage risk and build wealth, and collaborate on shared goals, in a way that optimizes for robustness to outside pressures.

The goal is not to remake the world in Ethereum's image, where all finance is disintermediated, all governance happens through DAOs, and everyone gets a blockchain-based UBI delivered straight to their social-recovery wallet. The goal is the opposite: it's de-totalization. It's to reduce the stakes of the war in heaven by preventing the winner from having total victory (ie. total control over other human beings), and preventing the loser from suffering total defeat. To create digital islands of stability in a chaotic era. To enable interdependence that cannot be weaponized.

Ethereum's role is to create "digital space" where different entities can cooperate and interact. Communications channels enable interaction, but communication channels are not "space": they do not let you create single unique objects that canonically represent some social arrangement that changes over time. Money is one important example. Multisigs that can change their members, showing persistence exceeding that of any one person or one public key, are another. Various market and governance structures are a third. There are more.

I think now is the time to double down, with greater clarity. Do not try to be Apple or Google, seeing crypto as a tech sector that enables efficiency or shininess. Instead, build our part of the sanctuary tech ecosystem - the "shared digital space with no owner" that enables both open finance and much more. More actively build toward a full-stack ecosystem: both upward to the wallet and application layer (incl AI as interface) and downward to the OS, hardware, even physical/bio security levels.

Ultimately, tech is worthless without users. But look for users, both individual and institutional, for whom sanctuary tech is exactly the thing they need. Optimize payments, defi, decentralized social, and other applications precisely for those users, and those goals, which centralized tech will not serve. We have many allies, including many outside of "crypto". It's time we work together with an open mind and move forward.

[vitalik.eth @VitalikButerin]

Finally, the block building pipeline.

In Glamsterdam, Ethereum is getting ePBS, which lets proposers outsource to a free permissionless market of block builders.

This ensures that block builder centralization does not creep into staking centralization, but it leaves the question: what do we do about block builder centralization? And what are the _other_ problems in the block building pipeline that need to be addressed, and how? This has both in-protocol and extra-protocol components.

## FOCIL

FOCIL is the first step into in-protocol multi-participant block building. FOCIL lets 16 randomly-selected attesters each choose a few transactions, which *must* be included somewhere in the block (the block gets rejected otherwise). This means that even if 100% of block building is taken over by one hostile actor, they cannot prevent transactions from being included, because the FOCILers will push them in.

## "Big FOCIL"

This is more speculative, but has been discussed as a possible next step. The idea is to make the FOCILs bigger, so they can include all of the transactions in the block.

We avoid duplication by having the i'th FOCIL'er by default only include (i) txs whose sender address's first hex char is i, and (ii) txs that were around but not included in the previous slot. So at the cost of one slot delay, only censored txs risk duplication.

Taking this to its logical conclusion, the builder's role could become reduced to ONLY including "MEV-relevant" transactions (eg. DEX arbitrage), and computing the state transition.

## Encrypted mempools

Encrypted mempools are one solution being explored to solve "toxic MEV": attacks such as sandwiching and frontrunning, which are exploitative against users. If a transaction is encrypted until it's included, no one gets the opportunity to "wrap" it in a hostile way.

The technical challenge is: how to guarantee validity in a mempool-friendly and inclusion-friendly way that is efficient, and what technique to use to guarantee that the transaction will actually get decrypted once the block is made (and not before).

## The transaction ingress layer

One thing often ignored in discussions of MEV, privacy, and other issues is the network layer: what happens in between a user sending out a transaction, and that transaction making it into a block? There are many risks if a hostile actor sees a tx "in the clear" inflight:

* If it's a defi trade or otherwise MEV-relevant, they can sandwich it
* In many applications, they can prepend some other action which invalidates it, not stealing money, but "griefing" you, causing you to waste time and gas fees
* If you are sending a sensitive tx through a privacy protocol, even if it's all private onchain, if you send it through an RPC, the RPC can see what you did, if you send it through the public mempool, any analytics agency that runs many nodes will see what you did

There has recently been increasing work on network-layer anonymization for transactions: exploring using Tor for routing transactions, ideas around building a custom ethereum-focused mixnet, non-mixnet designs that are more latency-minimized (but bandwidth-heavier, which is ok for transactions as they are tiny) like Flashnet, etc. This is an open design space, I expect the kohaku initiative @ncsgy will be interested in integrating pluggable support for such protocols, like it is for onchain privacy protocols.

There is also room for doing (benign, pro-user) things to transactions before including them onchain; this is very relevant for defi. Basically, we want ideal order-matching, as a passive feature of the network layer without dependence on servers. Of course enabling good uses of this without enabling sandwiching involves cryptography or other security, some important challenges there.

## Long-term distributed block building

There is a dream, that we can make Ethereum truly like BitTorrent: able to process far more transactions than any single server needs to ever coalesce locally. The challenge with this vision is that Ethereum has (and indeed a core value proposition is) synchronous shared state, so any tx could in principle depend on any other tx. This centralizes block building.

"Big FOCIL" handles this partially, and it could be done extra-protocol too, but you still need one central actor to put everything in order and execute it.

We could come up with designs that address this. One idea is to do the same thing that we want to do for state: acknowledge that >95% of Ethereum's activity doesn't really _need_ full globalness, though the 5% that does is often high-value, and create new categories of txs that are less global, and so friendly to fully distributed building, and make them much cheaper, while leaving the current tx types in place but (relatively) more expensive.

This is also an open and exciting long-term future design space.
