Bitcoin Hopes and Desires > 자유게시판

So now we all know the whole technique of bitcoin functioning and how Bitcoins can be used for making all sorts of actual transactions. Bitcoins are exchangeable for fiat forex via cryptocurrency exchanges and can be utilized to make purchases from merchants and retailers that settle for them. Greg Sanders: Yeah, if I can leap in. Mark Erhardt: So I’m questioning, one among the issues that seems to jump out after i hear you speaking about that is, what if one aspect retains making updates however not concluding it? And we’ve always gone back and forth between those, because we don’t know if we must always do a less complicated version first and watch for later to do a way more advanced model, or if we should simply bounce to the more advanced version proper now. Because we’ve at all times been discussing the fact that asserting, having the channel announcement level to a specific onchain output, was fairly dangerous for privacy and that we may in all probability do better. So, these are issues that we’ve at all times been simply hand-wavy about how we'd try this sooner or later. Read More: Amid value drops and elevated regulation, what’s the future of cryptocurrency?

But I don’t assume we’ll permit you to have any type of multiplier, because one of the opposite ideas was that you possibly can additionally simply announce some UTXOs that you simply own, with the proof that you simply personal them, with a total value of, for example, 2 bitcoin, and then that may grant you the ability to announce as much as X times that in channels without having to point to any particular onchain output. I didn’t think it was too dangerous, but the one key difference here is that for the fee channels with penalties as currently designed, it’s necessitating that you simply store these secret nonces eternally until channel shut. These charts are cardinal a part of the entire affair as with them traders are in a position to foretell the movement close to accuracy. But, realizing that the markets never close is a useful safeguard to have. If you have one other Lightning-like channel specification that you simply coded up or a custom channel sort, you may also embody that in this channel announcement and it will simply work. That’s why we’re not doing that proper now, and that’s why most individuals will just keep asserting the output that basically corresponds to the channel so that when it gets spent, folks truly discover it and can remove it from that graph and know that they cannot route by that channel anymore.

I think we’re going to stick with a simple model, where you enable pointing to any sort of output to pay for youtu.be your channel. PTLC fixes that by ensuring that as an alternative of utilizing the preimage of a SHA256 hash and its hash, we’re going to make use of elliptic curve factors and their non-public keys. This could seem pointless on condition that BIP32 already offers prolonged personal keys (xprvs) that may be shared between signing wallets. Maybe we will start with t-bast. Can the channel keep open when the UTXO will get spent? And then again, how do you make it possible for the identical UTXO shouldn't be reused for the announcement; and what occurs if that UTXO gets spent? So, will we have to be protecting observe of the UTXO actually not being moved while it's the stand-in to have announced the channel? Mike Schmidt: The taproot and MuSig2 channel discussion considerably leads into the up to date channel announcement dialogue and the way gossip protocol would have to be upgraded so as to assist shifting to P2TR outputs. So, we need to alter that, because we want to permit taproot, which suggests permitting additionally enter, particularly if we use MuSig2; we don’t want to reveal the inner keys.

And proper now, it’s going to use the identical payment hash with all these nodes, which signifies that if somebody owns two of the nodes in the trail, they're studying information, and that is bad for privateness. Right now, whenever you ship a payment, this payment is going to go through a number of nodes on the community. Bastien Teinturier: Sure. So right now, once we announced the channel on the community, we explicitly introduced node IDs and the Bitcoin keys that are contained in the multisig 2-of-2, and people verified that the output that we're referencing is definitely locked with the script hash of multisig 2-of-2 of those two keys, so you possibly can solely use it with scripts that actually follow the format of Lightning channels with out taproot. Mike Schmidt: Murch or t-bast, any other feedback on taproot and MuSig2 channels? Mike Schmidt: Go ahead, Murch. Mike Schmidt: Next section from the Summit mentioned PTLCs and redundant overpayments. Bastien Teinturier: Okay, so PTLCs are a change that's allowed by taproot and adaptor signatures.
