A federal judge on Monday
struck down Donald Trump’s executive order blocking wind energy projects,
saying the effort to halt virtually all leasing of wind farms on federal lands and waters was
“arbitrary and capricious” and violates U.S. law.
Judge Patti Saris of the U.S. District Court for the District of Massachusetts
vacated Trump’s Jan. 20 executive order blocking wind energy projects and declared it unlawful.
Saris ruled in favor of a coalition of…
Very happy to see Trump’s illegal block on wind farm development thrown out by a judge, along with the Orwellian justification given for it—a classic inversion of the truth. Every accusation is a confession, etc. (“The government argued that the states’ claims amount to nothing more than a policy disagreement over preferences for wind versus fossil fuel energy development that is outside the federal court’s jurisdiction.”)

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.
