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.

so wait, why don't we use the fermat prime field F_{2^16+1} for small circuits? obviously smooth and easy generator (!) => multiplications via log-table are easy, conversions fit in L2 cache => can special case the 0 element, so those are free => nonzero elems fit in 16bit

9/ Why does this matter? Data sovereignty is the antidote to the mediocre, centralized web we've been stuck with. Groundmist Library is an example of what the web *could* look like - your private and public data effortlessly linked, without loss of ownership or control.

8/ On the public side, for the information you choose to publish, 1 click makes it viewable by anyone (and any app interfacing with the AT Protocol). It can follow you anywhere you want to go and will never succumb to link rot. You can easily display it a million different ways.

7/ My recent experiment, Groundmist Library, bridges these worlds: My goal was something that's both a personal content archive and a public curated collection. When private, it's completely private - it lives on your devices, and *nobody* has access to your data other than YOU.

🧵 I've been experimenting with combining local-first software and the AT Protocol (atproto) to play with the design space of apps that live at both ends of the privacy spectrum - maximally private AND maximally public, without some of the downsides of the modern web.  Why? 👇

at a glance this is just a small, backwards-compatible protocol tweak. that's true, but the implications are pretty big. to date the amount of data you need to store to fully verify the next write to someone's repo grows with their repo's size. we're able to make it constant instead. but how? 1/10

OK, the fun has begun. Torrents at the Internet Archive absolutely work. It's the superior way to download massive items, of which there are many. However, to protect system resources, larger items don't always have torrents fully generated for them. But the current era kind of needs them.
