So now we know the whole means of bitcoin functioning and the way Bitcoins can be used for making all sorts of actual transactions. Bitcoins are exchangeable for fiat foreign money through cryptocurrency exchanges and can be utilized to make purchases from merchants and retailers that accept them. Greg Sanders: Yeah, if I can jump in. Mark Erhardt: So I’m questioning, one of the issues that appears to leap check out here once i hear you talking about this is, what if one aspect retains making updates however not concluding it? And we’ve all the time gone again and forth between those, as a result of we don’t know if we must always do a less complicated model first and wait for later to do a much more complex model, or if we must always simply jump to the extra complex version proper now. Because we’ve all the time been discussing the fact that saying, having the channel announcement level to a particular onchain output, was fairly dangerous for privateness and that we may most likely do better. So, these are things that we’ve at all times been simply hand-wavy about how we might try this sooner or later.

But I don’t assume we’ll let you have any type of multiplier, because certainly one of the opposite concepts was that you may additionally just announce some UTXOs that you simply personal, with the proof that you own them, with a total value of, for example, 2 bitcoin, and then that would grant you the power to announce as much as X occasions that in channels without having to point to any particular onchain output. I didn’t suppose it was too bad, however the one key distinction right here is that for the cost channels with penalties as at present designed, it’s necessitating that you store these secret nonces ceaselessly till channel close. These charts are cardinal part of the entire affair as with them traders are able to foretell the motion close to accuracy. But, understanding that the markets by no means shut is a useful safeguard to have. If you have another Lightning-like channel specification that you simply coded up or a custom channel kind, you can also include that on this channel announcement and it'll simply work. That’s why we’re not doing that proper now, and that’s why most people will just keep announcing the output that actually corresponds to the channel so that when it gets spent, folks actually discover it and might remove it from that graph and know that they can't route through that channel anymore.

I feel we’re going to keep on with a easy model, the place you permit pointing to any sort of output to pay for your channel. PTLC fixes that by making sure 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 private keys. This may seem unnecessary on condition that BIP32 already provides extended non-public keys (xprvs) that may be shared between signing wallets. Maybe we are able to begin with t-bast. Can the channel keep open when the UTXO gets spent? And however, how do you make it possible for the identical UTXO shouldn't be reused for the announcement; and what occurs if that UTXO will get spent? So, will we should be protecting monitor of the UTXO really not being moved whereas 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 how gossip protocol would should be upgraded as a way to assist moving to P2TR outputs. So, we want to change that, as a result of we'd like to permit taproot, which means permitting also enter, particularly if we use MuSig2; we don’t wish to reveal the interior keys.

And proper now, it’s going to make use of the identical payment hash with all these nodes, which means that if someone owns two of the nodes in the path, they are learning data, and this is dangerous for privateness. Right now, whenever you ship a payment, this payment goes to go through multiple nodes on the community. Bastien Teinturier: Sure. So right now, after 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 are referencing is definitely locked with the script hash of multisig 2-of-2 of these two keys, so you'll be able to solely use it with scripts that actually observe the format of Lightning channels without taproot. Mike Schmidt: Murch or t-bast, some other comments on taproot and MuSig2 channels? Mike Schmidt: Go ahead, Murch. Mike Schmidt: Next part from the Summit discussed PTLCs and redundant overpayments. Bastien Teinturier: Okay, so PTLCs are a change that's allowed by taproot and adaptor signatures.
