Won wallet lmao Seoul at Bitcoin Conf!
Supports legacy addresses hardware the only a
Quantum resistant!
Legacy addresses (1…) are not quantum proof, are they?
Yeah it's p2pkh. Quantum resistant until you spend from that address. So as long as you never reuse an address you are safe.
All this quantum resistance stuff is noise, honestly. Just move your corn to a p2pkh or p2sh address and focus on more important shit. When we activate CTV we can build mass migration tools. Maybe people will finally shut up about empty mempools for a little while. 😅
Oops, use p2wsh and p2wpkh to cram more transactions into the blocks. Those are quantum resistant segwit addresses.
Noob question: wouldn't any address that hashes the public key be quantum resistant like Segwit/Bech32 addresses?
yup, basically every address type except taproot
I think there is like a super legacy address type that doesn't hash the pubkey. This is where satoshi's mining rewards live. If those coins start getting spent we'll know something is up. But as for protecting your own wealth all you gotta do is avoid taproot and use wallet software that follows best practices and doesn't reuse addresses. EZPZ
Interesting. I didn't realize that about taproot addresses as Ive never really studied them mostly because ive never used a wallet that generates them lol
Yeah the thinking was quantum computing is probably bullshit so why not expose the pubkey. It lets you do all kinds of cool key tweaking crypto tricks. But then they also did x only pubkeys and handicapped key tweaking. lol oops
Well fuck around and find out I guess!
Yeah we'll probably remove x-only pubkeys in a future soft fork.
Tangential question but are you aware of a graphical visualizer that shows the identification of a public key on the curve being generated? That would be neat to watch if it started slowly the. Ramped up fast so you could show someone visually why it infeasible to brute force reverse it.
Not off the top of my head. I've seen something like this before and the more technically accurate it is the less sense it makes.
I think part of ECDSA has you modulo the point over a reduced range so in practice it jumps all over the place and doesn't display a smoothe curve. It looks like a bunch of dots randomly appearing on a Cartesian plane.
except taproot ? sounds weird as p2tr is even more recent. source ? thanks
Ah, they make a good point. If you spend a 'quantum resistant' UTXO from an older address type the pubkey is visible to the world while that transaction is waiting to get mined. So you better set a high enough fee rate to get it mined before some quantum computer cracks it.
In practice, this time window will be short under normal circumstances and most users will be spending small amounts, probably not worth the cost to crack the privkey.
