In 2026, I plan to be fully back to decentralized social.If we want a better society, we need better mass communication tools. We need mass communication tools that surface the best information and arguments and help people find points of agreement. We need mass communication tools that serve the user's long-term interest, not maximize short-term engagement. There is no simple trick that solves these problems. But there is one important place to start: more competition. Decentralization is the way to enable ...

RT vitalik.eth (@VitalikButerin)I'm definitely more in favor of native rollups than before.Before a big reason why I was against, is that a native rollup precompile must either be used in "zk mode" or in "optimistic mode", and ZK-EVMs were too immature for ZK mode, and so if we give L2s the choices "have 2-7 day withdrawal time with proofs backed by ethereum's full faith and credit" vs "instant withdrawals but you're on your own for proofs", they'll pick the former, and that's really bad for ethereum's comp ...

We need more DAOs - but different and better DAOs.The original drive to build Ethereum was heavily inspired by decentralized autonomous organizations: systems of code and rules that lived on decentralized networks that could manage resources and direct activity, more efficiently and more robustly than traditional governments and corporations could.Since then, the concept of DAOs has migrated to essentially referring to a treasury controlled by token holder voting - a design which "works", hence why it got c ...

An important, and perenially underrated, aspect of "trustlessness", "passing the walkaway test" and "self-sovereignty" is protocol simplicity.Even if a protocol is super decentralized with hundreds of thousands of nodes, and it has 49% byzantine fault tolerance, and nodes fully verify everything with quantum-safe peerdas and starks, if the protocol is an unwieldy mess of hundreds of thousands of lines of code and five forms of PhD-level cryptography, ultimately that protocol fails all three tests:* It's not ...

RT Séb Krier (@sebkrier)It's remarkable, and depressing, to realize how few people are truly polycentric / classically liberal. Particularly amongst highly educated elites. They may mood affiliate but it doesn't take much for them to eventually demand some desire to prohibit/limit things that don't affect them, justified on the basis of some arbitrary higher principle or some double standard.As soon as the tables turn and they're in power, they will display the same caveman behaviours as those they claimed ...

2026 is the year that we take back lost ground in terms of self-sovereignty and trustlessness.Some of what this practically means:Full nodes: thanks to ZK-EVM and BAL, it will once again become easier to locally run a node and verify the Ethereum chain on your own computer.Helios: actually verify the data you're receiving from RPCs instead of blindly trusting it.ORAM, PIR: ask for data from RPCs without revealing which data you're asking, so you can access dapps without your access patterns being sold off t ...

RT matrianarcat (@Fatalmeh)As an advisor to the @ethereumfndnTo our community in Iran, our eyes and thoughts are with you and the entire Iranian population. We see you bravely fighting tyranny and being brutally silenced, all your rights scraped, and communications cutMany of you travelled from Iran to attend @EFDevcon @EFDevconnect and @ETHGlobal.

In 2014, there was a vision: you can have permissionless, decentralized applications that could support finance, social media, ride sharing, governing organizations, crowdfunding, potentially create an entire alternative web, all on the backs of a suite of technologies.Ethereum: the blockchain. The world computer that could give any application its shared memory.Whisper: the data layer. Messages too expensive for a blockchain, that do no need consensus.Swarm: the storage layer. Store files for long-term acc ...

Ethereum itself must pass the walkaway test.Ethereum is meant to be a home for trustless and trust-minimized applications, whether in finance, governance or elsewhere. It must support applications that are more like tools - the hammer that once you buy it's yours - than like services that lose all functionality once the vendor loses interest in maintaining them (or worse, gets hacked or becomes value-extractive). Even when applications do have functionality that depends on a vendor, Ethereum can help reduce ...

If done properly, this is a very good move.I hope it can be verifiable and replicable (probably means publishing all tweets and anonymized likes with 4 week delay).This would not solve all problems, but it would very effectively address concerns about algorithmic transparency that I and many other members of the public have been raising.I actually think 4 weeks may be over-ambitious, because it means the algo would need to change that often to stay ahead of people gaming it; hence why I proposed 1 year in m ...
