6 sats \ 1 reply \ @OT 5h \ on: MARA Slipstream now available as a permissionless public good bitcoin

Hmmm, I just checked the other day and saw some KYC/client code BS.

If they've done this to help CC users get their low entropy TX through then hats off to them.

Fair enough, but for Bitcoin to work we need to be able to use software generated wallets. Otherwise it becomes obscure and niche rather than the ideal hard money for everyone.

126 sats \ 1 reply \ @OT 2 Aug \ parent \ on: Can we have a serious talk about the LARP in Bitcoin bitcoin

In this particular situation users have already set up a flawed wallet. Coinkite can fix the vulnerability but as soon as they disclose to the pubic it wouldn't take long for an attacker to find the exploit and steal the slow mover coins.

I think it's a great idea particularily for when quantum resistant addresses become available.

It adds some complexity to ones cold storage setup, but once set up you'd probably only need to deal with it once a year.

I might add one thing. If this is for an emergency, broadcasting the TX fees needs to be set high as we have no idea what fees will be at any given time in the future.

People still set up wallets with low entropy. As soon as its public, thieves would go looking for the exploit and find it fast.

If this CC exploit was found and disclosed to Coinkite the outcome would have still been lost coins. Maybe not as many.

He's kinda right. Coldcard was marketed as being the most cypher punk Bitcoin maximalist hardware wallet. It was shilled by many influencers like Odel, Marty, BTCsessions etc.

Say a similar vulnerability was found in a Ledger there'd probably be 10x the amount of Bitcoin stolen.

100% it has. I was thinking about this yesterday, if I'd have lost everything or if Bitcoin went to zero. With the knowledge I've learned I'm pretty confident I can make a comeback.

Sell everything!!!

But she says that every bear market. Could be a bottom signal!

105 sats \ 1 reply \ @OT 31 Jul \ parent \ on: Coldcard Mk2, Mk3, Mk4, Mk5, and Q Firmware Security Vulnerability security bitcoin bitdevs

My better half has been convincing me to sell all day...

I think you're right though. If the only way to secure bitcoin is to roll your own entropy the number of bitcoiners diminishes.

Still it was a vulnerability, not a quantum hack.
