Abstract: We study methods to enhance privacy in blockchain transactions from an economic angle. We consider mechanisms for privacy-aware users whose utility depends not only on the outcome of the mechanism but also negatively on the exposure of their economic preferences. Specifically, we study two auction-theoretic settings with privacy-aware users. First, we analyze an order flow auction, where a user auctions off to specialized agents, called searchers, the right to execute her transaction while maintaining a degree of privacy. We examine how the degree of privacy affects the revenue of the auction and, broadly, the net utility of the privacy-aware user. In this new setting, we describe the optimal auction, which is a sealed-bid auction. Subsequently, we analyze a variant of a Dutch auction in which the user gradually decreases the price and the degree of privacy until the transaction is sold. We compare the revenue of this auction to that of the optimal one as a function of the number of communication rounds. Then, we introduce a two-sided market - a privacy marketplace - with multiple users selling their transactions under their privacy preferences to multiple searchers. We propose a posted-price mechanism for the two-sided market that guarantees constant approximation of the optimal social welfare while maintaining incentive compatibility (from both sides of the market) and budget balance. This work builds on the emerging line of research that attempts to improve the performance of economic mechanisms by appending cryptographic primitives to them.

@ben@a11y.infoModerators of tech(-adjacent) Discord servers: are y’all getting hit with spam of people advertising their services for AI or blockchain projects?
I ask because a few servers I mod have had a very noticeable uptick of such drive-by self-promo. It’s specifically webdev servers, and none of those servers have advertised themselves as spaces for AI or blockchain interests…

@pre@boing.worldDay two introduced again by Mad bitcoins .
Then the history of art on bitcoin includes satoshi and his original logo, ASCII art in the Blockchain, Cassius coins with scratch off keys, these pictured images of fake satoshi and 200 logos.
Exploded from there, trading cards, the rare Pepe's.
What makes it bitcoin art?
Symbology. The logo. Religious symbology. Is it a cult?
Memes. Memes catch and go in a fashion which is unpredictable and fits the whole history to a timeline.
Art builds culture and heros proliferate bitcoin culture for all.
Art traditionally goes up in value but none of it seems to outpace bitcoin itself.
Some is for sale in the gallery but it'll unlikely be a better but then 30 percent discount bitcoin today 😆

@thomasafine@social.linux.pizzaFirefox is jumping the shark with this AI thing. A web browser helps you browse the web. it doesn't steal and summarize web content in order to prevent you from visiting web sites.
I think it's barely less disgusting than the blockchain web nonsense. But I acknowledge that it is possible that it is actually even more disgusting.
