Agree, but do we really know that Satoshi's identity was strong against powerful attackers?
He could be known by some government without him knowing it.
He could also already be locked in a cage somewhere, or worse, without us knowing about it.

@npub1j8d…26k2 This looks amazing. But why do you have to select which two signers to sign with at 1:34 in the clip? On the next screen, the app seems to automatically identify which of the two devices you plugged in.

2023-10-25 12:14:03

- reply

It's cool! I think you should shift "supply" and "percent" columns down by one and put 0's on the top row. It'd make it more intuitive (for me at least).
But then you'd need another row at the bottom (epoch 34, year 2140) and put 0 for reward.

There is no such capability in amethyst, right? Of course you can copy the npub and create an account with it, but a Malkovich button gives you a very easy way to do it. Just to temporarily transcend into someone else's persona.

Just read the disclosure of a severe vulnerability in libbitcoin's `bx` tool that limits seed entropy to 32 bits.
https://milksad.info/disclosure.html
Got me wondering about security of various multi/threshold signature wallets.
Traditional OP_CHECKMULTISIG adds one bit of entropy for each extra signer, given that the individual pubkeys are disclosed. A 2of2 multisig would be 33 bits of entropy and also easily identifiable as vulnerable once a spending tx is published.
But using taproot and musig2, the individual pubkeys are not disclosed, so the number of bits is doubled for each extra sig. A 2of2 multisig would be 64 bits of entropy, and not easily identifiable as vulnerable.
Amirite? @npub1j5m…sd5c @npub1vad…nuu7
Haven't thought about musig2 this way before. It's a belts and suspenders type of thing in case entropy turns out to suck.

The danger isn't double spends, the danger is censorship. "All he can accomplish" is misleading.

2023-08-04 17:00:20

I agree that it doesn't change the security model, and Bitrefill doesn't say that. In practice, however, disabling opt-in RBF has worked pretty well so far. Since this seems to be changing, we're actively discussing how to approach it going forward.
We're having small transactions only and can thus afford to be screwed (we're not quite there yet), which serves as a signal for us to adapt to a new environment.

2023-07-20 00:13:43

Yeah, ditch all but the one about duress/decoy wallets. I think that's a really important topic that needs more thought.

2023-07-13 16:20:41

- reply

Yes, that's correct!
But I do think that various coinjoin protocols set different sighash flags. I guess @npub1klk…x3vt can answer that.

2023-07-13 13:58:49

- reply

Yes each input requires a different signature (even if they spend from the same address),
There are no signatures on the outputs. The full transaction, including its outputs, is covered by the signatures on the inputs. But you can somewhat modify (using sighash flags) what the signature covers (commits to) when you make the signature.

2023-07-13 11:25:41

- reply

The sighash flags are set in the signature itself. The user that signs an input sets eg SIGHASH_ALL when signing. This means that any changes among the outputs will render the signature invalid.

Sure enough, I downloaded bitcoin 0.8.6 and sure enough, I could double click to start it (though it fails due to missing legacy lib). It has mime type application/x-executable instead of application/x-sharedlib

This seems to be the issue: https://fostips.com/double-click-run-elf-ubuntu/
But seriously, why???

2023-05-13 10:44:35

Decided to try Bitcoin Core GUI. Kinda disappointed. This is what happens when I double-click bitcoin-qt:
https://nostr.build/i/96a26e619e706e481f197452c8bcbd372f6f1af9e210227370853cc04deefa6f.jpg
So in order to run the GUI you have to open a *terminal* and run
$ bla/bla/bla/bitcoin-24.0.1/bin/bitcoin-qt
Is there some good reason why double-clicking it doesn't work?

Could you hash rhe inputs one by one and xor the hashes? Same for outputs?

Sed gurus: Say I have this input in in.txt:
The quick brown fox
jumps over the lazy
dog
The quick brown fox
jumps https://example.com/1[Example1] over the lazy
dog
I want the output to look like this:
The quick brown fox
jumps over the lazy
dog
https://example.com/1
The quick brown fox
jumps https://example.com/1[Example1] over the lazy
dog
So I want all URLs inside paragraphs to be copied to right before the paragraph with two line-breaks after it. Any takers? Other tool are ok too, if they're available on a typical slimmed linux machine.
