A funny idea for a "vampire Uber" app: both drivers and passengers use Uber with zkTLS, and submit their matches to vampire Uber. On vampire Uber, we remove Uber's cut of the profit, so the driver is paid more and the passenger pays less

This is the right response to the Mississippi law from Bluesky.

"Age verification" laws are nothing more than a massive expansion of government surveillance and censorship. They make kids less safe, not more safe.

Get a VPN and call your lawmakers. Time to fight.

Bluesky Goes Dark in Mississippi Over Age Verification Law
Bluesky has chosen to block access in the state rather than risk potential fines of up to $10,000 per violation.

I'm increasingly convinced that interactive zk is the correct tool for digital ID systems, more than zk-SNARKs

Is it worse to show a physical ID at the liquor store, or to tap your Google Wallet and create a zk proof of age (and a digital trace of this interaction)?

Zcashers support trans rights.

"And so, if you can’t do these things [such as getting trans people hormones even though it may be illegal where they are] —that might be disapproved by authority, but are actually perfectly ethical and the right thing to do— because you fear the consequences? Then that leads to a worse society."

I'm co-organising a Community Privacy Residency in Taipei next Feb: focused on researching, co-designing, and prototyping applications for community privacy 💗

We invite community builders, designers, researchers, and advocates for digital safety and privacy to join us.

Arke: Scalable and Byzantine Fault Tolerant Privacy-Preserving Contact Discovery
(Nicolas Mohnblatt, Alberto Sonnino, Kobi Gurkan, Philipp Jovanovic) ia.cr/2023/1218
Abstract. Contact discovery is a crucial component of social applications, facilitating interactions between registered contacts. This work introduces Arke, a novel approach to contact discovery that addresses the limitations of existing solutions in terms of privacy, scalability, and reliance on trusted third parties. Arke ensures the unlinkability of user interactions, mitigates enumeration attacks, and operates without single points of failure or trust. Notably, Arke is the first contact discovery system whose performance is independent of the total number of users and the first that can operate in a Byzantine setting. It achieves its privacy goals through an unlinkable handshake mechanism built on top of an identity-based non-interactive key exchange. By leveraging a custom distributed architecture, Arke forgoes the expense of consensus to achieve scalability while maintaining consistency in a Byzantine fault tolerant environment. Performance evaluations demonstrate that Arke can support enough throughput to operate at a planetary scale while maintaining sub-second latencies in a large geo-distributed setting.
