Excited to present Uncle Maker tomorrow at ACM CCS 2024! The published version of the paper contains new results, such as an evaluation of the attack's impact on Ethereum's difficulty, and the profits F2Pool made. Check it out: dl.acm.org/doi/10.1145/35โ€ฆ

The Chief of Staff studied the polling data after the President's address. "Maybe she should smile more next time?" His aide nodded. "I'll tell the programmers." In a hidden room, keystrokes began crafting the smile that would ease the nation.

Can we design good transaction fee mechanisms (TFMs)? If so, what are the trade-offs? Together with Aviv Yaish, we show an impossibility for deterministic TFMs, and limitations for randomized TFMs. Paper: doi.org/10.48550/arXivโ€ฆ Read on for more details (1/10)

The lie in this statement cannot be overstated: It's not the occupation that led us to this moment. It's radical Islamic fundamentalism, very far from the true values of Islam. Hamas started blowing up buses in Israel right after an option for peace arose in the Oslo Accords.
