Fun fact: Bitcoin can be as secure as today WITHOUT ANY MINERS! (And no, I'm not talking about forking to PoS. I said "as secure" lol.) In fact, as long as everyone agrees on the hash of the last tip, you don't even need the internet. With quantum computers, it is possible to completely remove the need for Bitcoin mining in the long term while compromising hardly anything! The existing chain remains as a source of initial truth, and everything else remains offline. Double spending is not prevented by a network of verifiers, but by the laws of physics!
Learn all about it from Tuesday's lectures about the quantum promise and threat to Bitcoin.
@or_sattath (my Ph.D co-advisor and the S in LSZ) presented the promise, while I explained the threat πΏ
The lectures are in English, link to the video in the original post.
@or_sattath (BGU) opened with the optimistic side: public quantum money and one-shot signatures (Amos et al., Best Paper at Crypto), enabling "prudent contracts" and a Bitcoin upgrade path that eventually retires mining.
@DesheShai followed with the migration plan. Front-running during the broadcast-to-confirmation window is the real near-term surface. In flight: BIP-360 (soft-fork ramp for new signatures), cryptographic canaries as on-chain tripwires, Lifted FawkesCoin (LFC) for recovering legacy and lost addresses, and BIP-361 (Jameson Lopp et al.) as the roadmap.

~20% of Bitcoin's supply could be stolen by a quantum computer tomorrow.
This week we hosted Prof. @or_sattath and Dr. @DesheShai in Tel Aviv to break down what's actually at risk, what's already in flight, and what blockchain looks like after a post-quantum migration.

"Where do you store the password to your password manager?"
@boazeb's answer: a paper vault. AES-256 encrypted, Shamir-split, unlocked by scanning two QR codes. All offline.
Watch Boaz walk through @papervault_xyz live in the latest edition of the Underground.
Bitcoin has survived every threat thrown at it. Quantum computing is different.
Web3 Devs Underground Monthly Meetup | Quantum Money Special
π¨ NEXT WEEK - Happening in person in Tel Aviv!
Featuring: Prof. Or Sattath (@or_sattath), one of the world's leading quantum cryptography researchers, and Dr. Shai Wyborski (@DesheShai), quantum cryptography expert and former Kaspa core contributor.
Both are co-developers of the Lifted FawkesCoin protocol, the first complete post-quantum migration solution for a live blockchain.
What's on the table: post-quantum signatures, decentralized migration, quantum money as a cryptographic primitive, Q-Day timelines, and the solutions already being built: SHRIMPs, StarkWare's QSB, Commit-Delay-Reveal.
