323 sats \ 4 replies \ @endothermicdev 23h \ on: BOLT 11 - Is `n` mandatory or not? lightning
This piqued my curiosity so I hand decoded a bolt11 to check - it had s, p, d, x, c, r, and 9 tagged fields. I guess n is not typically included because you can calculate the public key from the message (bolt11) along with the signature. Omitting it saves space.
Of the tagged fields, only d or h should be included (a description or a hash of the description if it's too long to fit.) p and s are required for payment hash and payment secret, but n is optional. Those still have a mandatory length (even though they have a length field in the invoice) otherwise the reader wouldn't know what to do with them and shouldn't proceed. Keeping these fields with a data length parameter leaves some flexibility for future spec changes I suppose.
Is what this wants to say this: IF n exists, THEN parsing the public key correctly is so important that we MUST fail the payment if the length is wrong, since the public key will be used to verify the signature?
That's my interpretation as well.

Obsidian not being open source was one of the reasons I didn’t even start using it, haha
(But not necessarily a good reason, since I did use other closed-source software, like NVIDIA drivers.)

It's really just this line that's confusing, right? Because n isn't really mandatory.
A reader:
  • MUST fail the payment if any mandatory field (p, h, s, n) does not have the correct length (52, 52, 52, 53).
Because later it's more clear with:
A reader: ...
  • if a valid n field is provided:
  • MUST use the n field to validate the signature instead of performing public-key recovery.
  • If the signature is not compliant with the low-S standard rule<sup>low-S</sup>:
    • MUST fail the payment
If it confused you, I'm sure it's confused others. I think it's worthwhile to fix unclear wording in the spec.

I think he's got the OG standpoint wrong. I don't recall many people from early days ever talking about gold standards, not even the e-gold people. That narrative came later. It has to me (and most people around me) mostly been about not being censored and not being tricked; NgU isn't a must-have.

I might have disagreed before. I think I have come around to one page docs though - they’re easier to search and not that much harder to read. Though they need some decent structure

There's not a single mindset of course. This old thread gives some insight of what bitcoiners thought in 2011. There's some sound money / deflationary reasoning, but the majority isn't.

Can we see downzaps the same way we see zaps at some point? Something like this?
Seeing the amount of sats near the post/comment is not accurate anymore, I suggest showing only the total amount of sats+ccs, both upzapped and downzapped.
What would be the issue in showing downzaps? WOuld this make the outlawed tag irrelevant?
We, as stackers, could decide to hide posts by x unzaps same way we currently do with min amount of sats.
Newbies could have a preset amount of y by default, but in control to change it if desired.

I think the "safe" signup process is:
NOTE: Do not use their VPN service or your real IP at any time, also not during signup. Instead use mullvad (obscura perhaps even better). Now they cannot report your IP address.
  1. Open free account
  2. Do NOT give them a fallback email
  3. Once you have the free account, upgrade with bitcoin, pay through submarine swap

I think bitcoin self custody is pretty easy already. I think a better way to put the question is how to make secure self custody easier in a way that mitigates against catastrophic risk (i.e. a single point of failure leading to your entire stack being drained)
