So now we all know the entire means of bitcoin functioning and how Bitcoins can be utilized for making all sorts of actual transactions. Bitcoins are exchangeable for fiat forex by way of cryptocurrency exchanges and can be used to make purchases from merchants and retailers that accept them. Greg Sanders: Yeah, if I can soar in. Mark Erhardt: So I’m wondering, certainly one of the problems that seems to jump out after i hear you talking about that is, youtu.be what if one side keeps making updates but not concluding it? And we’ve always gone again and forth between those, because we don’t know if we should do a easier version first and look forward to later to do a much more advanced model, or if we should just leap to the more advanced model proper now. Because we’ve always been discussing the truth that announcing, having the channel announcement level to a specific onchain output, was quite dangerous for privateness and that we might most likely do better. So, these are issues that we’ve at all times been just hand-wavy about how we would do this sooner or later.

But I don’t think we’ll mean you can have any sort of multiplier, as a result of one of the other ideas was that you would also just announce some UTXOs that you just personal, with the proof that you own them, with a total value of, for instance, 2 bitcoin, after which that may grant you the ability to announce as much as X times that in channels with out having to level to any specific onchain output. I didn’t assume it was too dangerous, however the one key distinction right here is that for the payment channels with penalties as currently designed, it’s necessitating that you retailer these secret nonces ceaselessly until channel close. These charts are cardinal a part of the entire affair as with them traders are in a position to foretell the motion close to accuracy. But, realizing that the markets never close is a handy safeguard to have. When you've got one other Lightning-like channel specification that you coded up or a customized channel type, you can also embrace that on this channel announcement and it'll just work. That’s why we’re not doing that proper now, and that’s why most people will just keep announcing the output that basically corresponds to the channel in order that when it will get spent, people really discover it and may take away it from that graph and know that they can not route through that channel
re.

I believe we’re going to keep on with a easy version, the place you allow pointing to any sort of output to pay for your channel. PTLC fixes that by ensuring that as a substitute of using the preimage of a SHA256 hash and its hash, we’re going to use elliptic curve points and their private keys. This may seem unnecessary given that BIP32 already provides extended private keys (xprvs) that can be shared between signing wallets. Maybe we will begin with t-bast. Can the channel stay open when the UTXO will get spent? And however, how do you make it possible for the identical UTXO will not be reused for the announcement; and what occurs if that UTXO will get spent? So, will we have to be maintaining observe of the UTXO truly not being moved while it's the stand-in to have announced the channel? Mike Schmidt: The taproot and MuSig2 channel dialogue considerably leads into the updated channel announcement discussion and the way gossip protocol would must be upgraded with a view to support shifting to P2TR outputs. So, we'd like to change that, because we want to permit taproot, which means allowing additionally input, particularly if we use MuSig2; we don’t wish to reveal the in
keys.

And proper now, it’s going to use the same fee hash with all these nodes, which signifies that if somebody owns two of the nodes in the path, they are studying info, and that is bad for privacy. Right now, everytime you send a payment, this fee is going to undergo a number of nodes on the network. Bastien Teinturier: Sure. So right now, once we introduced the channel on the network, we explicitly announced node IDs and the Bitcoin keys that are contained in the multisig 2-of-2, and people verified that the output that we are referencing is definitelyscriptd with the script hash of multisig 2-of-2 of those two keys, so you'll be able to soscriptse it with scripts that actually comply with the format of Lightning channels with out taproot. Mike Schmidt: Murch or t-bast, every other feedback on taproot and MuSig2 channels? Mike Schmidt: Go forward, 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.
