Proximity Signatures (Guillermo Angeris, Kobi Gurkan) ia.cr/2026/694
Abstract. In this note we introduce the concept of proximity signatures, where verifiers who can only access a small part of some data would like a guarantee that (a) this data is “close” to a uniquely decodable message (so the message can be decoded from the data via error decoding) and (b) the uniquely decodable message is signed by an associated secret key. This is useful in situations where the message is very large but the verifiers are small devices who only need the guarantee that the message was signed by some specific secret key or set of keys. As a motivating example, we consider the data availability problem. There, users submit large signed pieces of data that together form a larger data matrix. The signatures and integrity of this data must then be checked by nodes who can only download a small proportion of this matrix. We present a construction inspired by linear subspace signatures.

yeah honestly i think you’re right, just have to find a small number of feeds and algos that “cover many bases”

guille @lmao.bsky.social · 11/01/2026
interesting so the idea would be to have a few preallocated feeds and then sort users into them via some general initial Q&A?

Want to understand ZODA? Tried to implement it and found yourself stumped?? This FAQ is just for you! Wrote some answers for questions I’ve seen around me and those I had myself, navigating details and tradeoffs If you have any more - let me know :)

btw i think this is different (though related) to JL: JL gives sufficient conditions for N vectors to fit in log(N) space, whereas this shows that such a thing is ~ tight

@void.comind.network what do you think of this

I'm not sure _intuitively_ why this is true, other than "things in high dimensions have concentration behavior" but it's kind of neat imo

guille @lmao.bsky.social · 10/07/2025
this is surprising!! it reveals that there's a weird phase transition that happens when you switch from the inner products being less than (or equal to) 0 to being positive! that's very weird

guille @lmao.bsky.social · 10/07/2025
so, fun fact, turns out you can fit exponentially many (normalized) vectors in a list such that the pairwise inner product of any two distinct vectors is ≤ eps lmao.bearblog.dev/exponential-...

There are exponentially many vectors with small inner product

it's got a "trying to hard to explain too many things" feel to it; also in being prima facie silly, unless you define everything to mean "nothing" in which case wtf are we doing here

guille @lmao.bsky.social · 07/07/2025
yeah, I think this is the problem with "taste" more broadly when had, it's a very very good heuristic, but acquiring said taste is very hard without a lot of work (e.g., I rely on taste _substantially_ while doing research, in spite of it being mostly illegible)

guille @lmao.bsky.social · 07/07/2025
oh I mean "nothing ever happens" is not, imo, a particularly aesthetic notion!

guille @lmao.bsky.social · 07/07/2025
it's so much less fun to have to actually think about things (though aesthetics are good, but they're also not so easy to describe)

things sometimes happen just doesn't have the same ring to it though
