Congratulations to Quanta Magazine and Natalie Wolchover. #Pulitzer

(9/12) Whenever F2Pool's block timestamps reach the point where mining difficulty is supposed to decrease, they artificially set them to be one second earlier. F2Pool has been executing this attack over the past two years, and the evidence has been hiding in plain sight! ...

5/ Blockchains are not going to be open ledgers forever. Just like the internet moved from HTTP to HTTPS as the default, blockchains are going to move to more private transactions over time, and this is a good thing for consumer protection. We should encourage it, not hinder it.

פרופ' עמית דניאלי, חבר סגל במחלקה למדעי המחשב באוניברסיטה העברית נעצר במהלך ההפגנה שקטה אתמול ללא כל פרובוקציות מצד המפגינים. אתם מוזמנים לצפות בסרטון. בושה למדינת ישראל.

0/n Protecting cryptocurrency procrastinators in the quantum era, a 🧵 about a newly published preprint by Or Sattath and myself. arxiv.org/abs/2303.06754

0/n A 🧵 about Or Sattath's fabulous new interactive map of some of the charted parts of the world of quantum cryptography. sattath.github.io/qcrypto-graph/

🎙️This week @annarrose & Kobi Gurkan chat with Or Sattath from Ben-Gurion University of the Negev Computer Science dept. They cover quantum computing + quantum cryptography, what these are, breakthroughs in the field and the impact on existing PoW systems Check it out! zeroknowledge.fm/288-2/

tl;dr of the discussion in this ep about quantum mining: arxiv.org/abs/1804.08118 “On the insecurity of quantum Bitcoin mining” miners in the classical world mine by repeatedly hashing, with variations of the block header, until the hash is smaller than the “difficulty” 1/13

Aharon's family (his sister-in-law, niece and nephews), a dear friend and colleague, were kidnapped in the recent terror attack. Hamas, please, mercy on the children.

🎙️This week, @annarrose & Nico | ge⬡metry research dive back into Quantum Cryptography with Or Sattath. They cover the move from pre- to post-quantum environments and the challenges in designing techniques do so. They also cover Quantum Money and more. Have a listen! zeroknowledge.fm/297-2/

Bolton will present our work, "51% Attack via Difficulty Increase with a Small Quantum Miner", at noon CT (5:30 hours from when this tweet is posted). The eprint: arxiv.org/abs/2403.08023 . A tl;dr version was posted by Shai ❤️ Deshe 💜 Wybors𐤊i 💙 (大胡子) x.com/desheshai/stat…… .

"This gives a polynomial time quantum algorithm for solving LWE." Is this real?
