So now we all know the entire strategy of bitcoin functioning and how Bitcoins can be utilized for making all kinds of actual transactions. Bitcoins are exchangeable for fiat currency via cryptocurrency exchanges and can be utilized to make purchases from merchants and retailers that settle for them. Greg Sanders: Yeah, if I can bounce in. Mark Erhardt: So I’m questioning, one in every of the problems that seems to leap out after i hear you talking about this is, what if one facet keeps making updates but not concluding it? And we’ve at all times gone back and forth between those, as a result of we don’t know if we should do a less complicated version first and await later to do a much more complex version, or if we should just jump to the extra advanced model proper now. Because we’ve at all times been discussing the truth that saying, having the channel announcement point to a specific onchain output, was quite dangerous for privateness and that we could probably do higher. So, these are things that we’ve always been just hand-wavy about how we would try this sooner or later.

But I don’t suppose we’ll permit you to have any kind of multiplier, because one in all the opposite ideas was that you could also just announce some UTXOs that you just personal, with the proof that you just personal them, with a complete worth of, for example, 2 bitcoin, and then that might grant you the flexibility to announce as much as X occasions that in channels with out having to level to any particular onchain output. I didn’t think it was too dangerous, but the one key difference right here is that for the fee channels with penalties as presently designed, it’s necessitating that you retailer these secret nonces perpetually until channel shut. These charts are cardinal a part of the entire affair as with them traders are ready to foretell the movement close to accuracy. But, realizing that the markets by no means shut is a handy safeguard to have. If you have one other Lightning-like channel specification that you simply coded up or a customized channel kind, you too can embody that on this channel announcement and it will simply work. That’s why we’re not doing that right now, and that’s why most people will simply keep asserting the output that basically corresponds to the channel so that when it gets spent, people truly notice it and may take away it from that graph and know that they can not route through that channel anymore.
I feel we’re going to stick with a simple version, where you permit pointing to any kind of output to pay to your channel. PTLC fixes that by making sure that instead of utilizing the preimage of a SHA256 hash and its hash, we’re going to make use of elliptic curve points and their non-public keys. This may seem pointless provided that BIP32 already gives prolonged personal keys (xprvs) that may 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 guantee that the identical UTXO shouldn’t be reused for the announcement; and what occurs if that UTXO gets spent? So, will we need to be protecting 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 discussion somewhat leads into the updated channel announcement discussion and how gossip protocol would need to be upgraded with a purpose to assist transferring to P2TR outputs. So, we need to alter that, because we want to allow taproot, which means permitting also enter, particularly if we use MuSig2; we don’t need to reveal the inner keys.
And https://2819main.com proper now, it’s going to make use of the same cost hash with all these nodes, which signifies that if somebody owns two of the nodes in the trail, they’re learning info, and this is dangerous for privacy. Right now, whenever you ship a cost, this fee is going to undergo a number of nodes on the community. Bastien Teinturier: Sure. So proper now, after we announced the channel on the network, we explicitly introduced node IDs and the Bitcoin keys which can be contained in the multisig 2-of-2, and people verified that the output that we’re referencing is actually locked with the script hash of multisig 2-of-2 of these two keys, so you may solely use it with scripts that basically follow the format of Lightning channels with out taproot. Mike Schmidt: Murch or t-bast, some other feedback on taproot and MuSig2 channels? Mike Schmidt: Go forward, Murch. Mike Schmidt: Next section from the Summit discussed PTLCs and redundant overpayments. Bastien Teinturier: Okay, so PTLCs are a change that’s allowed by taproot and adaptor signatures.
