Bcash is a fork of Bitcoin with a few things taken out. Mark Erhardt: Yeah, I was also surprised on how much Andrew had to write about that, but yeah, it turns out that humans are not computers, and while computers are good at some things, they are not great at other things, and while humans are good at some things, they’re not very good at calculating hashes and doing elliptic curve math on paper. How can I manually (on paper) calculate a Bitcoin public key from a private key? The first one, at first I thought this was kind of a funny question, but I actually got a lot of interest on the Stack Exchange, which is, "How can I manually, on paper, calculate a Bitcoin public key from a private key? And then async payments and trampoline, this is a longer-term effort, because it requires a lot of things that we’re working on but are not complete yet, before we can actually really do async payments.

So, since we’re still a very small team, maybe at some point, I hope that we are way too many specification writers, and then we need to split into different working groups. So, this could sound like, I guess from a priority perspective, I don’t think it’s quite there. There has been much speculation about what has happened, as GLBSE founder James McCarthy (Nefario) maintained relative silence on the Bitcoin forums, and fears multiplied that government law enforcement agencies were behind the shutdown. The reason why Bitcoin increases its worth so rapidly is due to the fact that the trust in this currency and its whole system increased that much in the last time. And that’s consensus change, and people working on spec details aren’t going to spend a lot of time lobbying for consensus changes, because they’re understandable. Provided you had a previous crypto wallet that’s funded, or someone else is transferring to you, you can now send cryptocurrency to the given address. In short, the spender can prove to a court or the public what they paid for. Maybe you can kind of put it to rest why that wasn’t a main discussion item during the meeting an

Mike Schmidt: Greg, for folks that may not be completely sure of the timelines for LN-Symmetry, they may say, "Hey, you had Greg on talking about Lightning, but LN-Symmetry wasn’t even in the LN Summit notes". Mike Schmidt: Greg, did you have anything to add? It would also be messy for the customer to spend from this transaction while it remains unconfirmed, as the enterprise will have to pay for discover this child spend when attempting to replace the parent. If a user tries to create a transaction that breaks the rules of the bitcoin protocol, it will automatically be rejected by the rest of the Bitcoin network. In particular, Poinsot looked at schemes for multiparty protocols with more than two participants, for which the current CPFP carve out transaction relay policy doesn’t work, requiring them to use transaction replacement mechanisms that may be vulnerable to transaction pinning. Mike Schmidt: There were two other items from the notes that we didn’t cover that I wanted to give either of you an opportunity to co
on.

Greg or t-bast, is there anything that you think the audience would benefit from knowing about those discussions? So, everyone is okay with just having all discussions on the IRC channel and we’ll start that and we’ll see how it goes. For example, for implementing splicing, the splice implementers created their own Signal or Discord groups to do day-to-day discussions without polluting the main IRC channel. And we decided that we should just pollute the main IRC channel for everything, because it has been dead for a month, and there was just no activity on that IRC channel, which was really sad. Bastien Teinturier: Hmm, on the first one, it was just about using threshold signatures, and I think there are cryptographic details to iron out before it becomes a real possibility. The answer to the second question, according to Emin Gün Sirer, is also (of course) NO (I think) (but read the post yourself). " And Andrew Poelstra answered this, providing some background, some other hand-calculation verification techniques that he’s used previously, including Codex32, and he estimates that it would take, even using some tricks and some helper lookup tables, that it would take about 1,500 hours to do that, 36 weeks of a full-time job, even using some of those tricks that he outlined in his answer.
