I built a social app for people who hate video calls. [mini meet dot cc] No schedule. 1 minute calls only. With "auto" mode. If you and your mutual are both online and haven't talked in a while. It creates a mini meet for you automatically. This is social for anti-social ppl.

New paper with @_patrickogrady and @commonwarexyz: The Carnot Bound. In leader-based consensus, the leader has to get each block out to every other processor. Erasure coding helps: instead of sending a full copy to everyone, the leader sends each processor a small fragment, from which the full block can be reconstructed once enough fragments are collected. The efficiency of this encoding is captured by the data expansion rate — the ratio of total data sent to payload size. This is a key parameter for throughput: the closer it is to 1, the closer maximum throughput gets to the raw network bandwidth. We prove that protocols with 2-round finality (one round of voting) can't achieve a data expansion rate below 2.5, which is a bound matched by existing protocols. We then show that an extra round of voting breaks the barrier, allowing rates arbitrarily close to 1. Links to paper and blog below...

Many of you have waited for a SHA2 hash that is also a valid signature. Finally, the wait is over:

The future belongs to ppl open to learning, building open tools, open services and open platforms. Open = Transparently enforced rules for permission-less participation. ... everything else is on a downward spiral.

Quick announcement: After long and heavy suffering :) the S-two white paper is finally out: eprint.iacr.org/2026/532 Although nothing new in regard to the basic principles (a circle STARK, etc.) the white paper yet contains several details of broader interest: - A formal description of the flat AIR circuit model (used by several contemporary zkVMs) - A thorough soundness analysis of multi-table proofs: If one does not use "lifted" FRI, taming the soundness error turns out to be more sophisticated as expected. We introduce the notion of "cross-domain correlated agreement", and show that multi-table FRI satisfies this property. - A discussion of adjusted conjectures, which takes into account the recent boost of proximity gaps counter examples. We believe that it is plausible to hope for acceptable list- and line-decodability properties up to the information-theoretic barrier, the Elias bound. Thanks for all the help from the StarkWare team, and in particular to Dmitry Krachun for the many helpful discussions around his counter example.

"we built crypto for agents" is the new "we built crypto for institutions" the reality is simple, crypto has use cases for everyone agents, institutions, consumers, unbanked, cypherpunks, traders, everyone

"Build me a deterministic hypervisor from scratch, make no mistakes"

It's not quite that simple and I'm not sure if it'll really go anywhere (at least I've learned a lot!), but turns out you can get kinda far in a couple months (with otherwise no prior knowledge on hypervisors): github.com/dergoegge/bedr…

there was an interesting part of this conversation where c-node (correctly) stated that your first amendment right to publish code does not additionally give you the right to run a business using said code there seems to be pretty clear agreement among lawyers i've chatted with that centralized privacy applications can not operate as businesses even if they don't custody funds centralized meaning the dev team // business running relayers, coordinators, sequencers, and more this isn't very surprising, but even if you're not taking fees, you still have to be somewhat careful basically anything that is run by a centralized operators // entity either is not making any money or is running some relatively serious risks

@Averiii congratulations! ♥️

I realize I’m outing myself rather abruptly here but making plans for EthCC and realizing one the groups I really want to connect with is moms in crypto! Any recommendations? I want to organize a brunch!! 🌴🤰🏻I need advice from the real ones!!

The idea that ZK'ing means that running nodes doesn't matter is itself misleading imo (and I was misled by this for a long time) You need to be able to not just verify the correctness of headers, but be able to read the chain, in a privacy-preserving and censorship-resistant way. RPCs do not provide this, even Helios and Colibri do not provide this. Ethereum's destiny is to be a network where the amount of data and transactions processed is far greater than the amount that needs to be handled by any one single node, but making this truly permissionless and chokepoint-free requires more work than ZK-proving alone.
