Recently, something came to light that many in the community probably overlooked: Vitalik is proposing a pretty serious reconfiguration of how we should think about Ethereum. It’s not a light narrative shift, but a reformulation of values that has very concrete technical implications.

The central question is brutal: what happens if tomorrow the main Ethereum developers disappear? Or if a government simply orders the censorship of certain transactions? Vitalik suggests that Ethereum should see itself as part of the “refuge technology” ecosystem — open-source tools that allow people to live, work, and accumulate wealth without relying on centralized intermediaries. It’s not just philosophy: it’s an extremely strict engineering standard.

Now, here’s where things get technical. The specific problem Ethereum faces is that block construction has become increasingly specialized. Builders have concentrated more power, transaction ordering rights are less distributed, and that means any major builder could theoretically reject certain transactions. It’s no longer a theoretical risk: it’s a real vulnerability.

That’s why FOCIL comes in. The proposal is actually quite elegant. Instead of removing builders, FOCIL introduces an Inclusion List mechanism that makes the inclusion of valid transactions no longer entirely dependent on the will of a single person. A committee of validators forms a list of transactions that must be included, and proposers have to respect that. Builders can still optimize the ordering and profit from MEV, but they lose the power to censor. FOCIL is confirmed to be included in the next major upgrade after Dencun, probably in the second half of 2026.

But FOCIL only solves part of the problem. Before a transaction reaches the block, has it already been exposed to the entire market? That’s where sandwich attacks and front-running come in. That’s why the community is working on cryptographic memory — basically, encrypting the content of the transaction until it’s included in a block. This way, searchers can’t see what you’re doing and can’t exploit you before your transaction goes through.

Together, FOCIL plus cryptographic memory plus ePBS form what some call the “censorship resistance trinity.” It’s not just another technical upgrade: it’s Ethereum returning to put censorship resistance at the core of the protocol’s design.

What many don’t understand is that decentralization is not a default state. It’s something that must be earned with code. Only when your transaction is truly intercepted or censored do most people realize that decentralization was never just a slogan, but a necessity. And that’s what makes blockchain unique: in a world where governments and corporations can shut down digital services at any moment, a network that keeps functioning even if all developers disappear tomorrow is something entirely different. That’s refuge technology.
