Quantum is one of the most compelling pieces of FUD in Bitcoin, we must understand how to address it.
Following on Main Stage at nostr:npub1dwah6u025f2yy9dgwlsndntlfy85vf0t2eze5rdg2mxg99k4mucqxz7c52 Istanbul: Hunter Beast on “Bitcoin’s Quantum Question”.
Discussion
US government is working actively to harden their cryptography to prepare for Post Quantum Standards.
Focus on sunsetting elliptic curve cryptography and RSA with a 2030-2035 horizon.
Physical qubit scale differently according to the technology used. For ions, for example, they double in around 5 years.
Let’s talk about software: Schor’s algorithm, developed in 1994 is able to efficiently factor large integers into their primes, effectively breaking today cryptography.
This is not feasible with classical computing, but a Quantum computer would allow this algorithm to work.
6,653,188 BTC are considered at risk of quantum attack.
The latest version of BIP360 is proposing P2TSH, Pay To Taproot Script Hash, and to move to SegWit v2, to address quantum issues.
