So now we know the whole means of bitcoin functioning and the way Bitcoins can be utilized for making all sorts of actual transactions. Bitcoins are exchangeable for fiat forex through cryptocurrency exchanges and can be used to make purchases from merchants and retailers that accept them. Greg Sanders: Yeah, if I can leap in. Mark Erhardt: So I’m wondering, one in all the problems that appears to jump out when i hear you talking about this is, what if one facet keeps making updates however not concluding it? And we’ve all the time gone back and forth between these, as a result of we don’t know if we should do a simpler model first and anticipate later to do a way more advanced model, or if we must always just jump to the extra complex model proper now. Because we’ve always been discussing the truth that asserting, having click the following webpage channel announcement level to a specific onchain output, was fairly unhealthy for privacy and that we may probably do better. So, these are issues that we’ve at all times been simply hand-wavy about how we'd try this in the future.

But I don’t think we’ll permit you to have any kind of multiplier, as a result of one of the other concepts was that you possibly can also just announce some UTXOs that you simply personal, with the proof that you just personal them, with a complete value of, for example, 2 bitcoin, after which that would 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 assume it was too unhealthy, however the one key distinction here is that for the cost channels with penalties as at present designed, it’s necessitating that you just retailer these secret nonces ceaselessly until channel close. These charts are cardinal part of the entire affair as with them traders are able to predict the motion close to accuracy. But, understanding that the markets by no means shut is a helpful safeguard to have. When you've got another Lightning-like channel specification that you coded up or a custom channel type, you too can include that in this channel announcement and it'll just work. That’s why we’re not doing that proper now, and that’s why most individuals will simply keep saying the output that really corresponds to the channel in order that when it will get spent, individuals truly notice it and might remove it from that graph and know that they can't route via that channel
re.
I think we’re going to follow a simple version, where you permit pointing to any type of output to pay to 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 use elliptic curve points and their personal keys. This could seem unnecessary given that BIP32 already supplies prolonged non-public keys (xprvs) that may be shared between signing wallets. Maybe we will begin with t-bast. Can the channel keep open when the UTXO will get spent? And alternatively, how do you be sure that the same UTXO just isn't reused for the announcement; and what happens if that UTXO gets spent? So, will we must be maintaining track of the UTXO actually not being moved while it is the stand-in to have introduced the channel? Mike Schmidt: The taproot and MuSig2 channel dialogue considerably leads into the updated channel announcement discussion and how gossip protocol would have to be upgraded to be able to assist transferring to P2TR outputs. So, we want to change that, as a result of we'd like to permit taproot, which implies allowing additionally enter, especially if we use MuSig2; we don’t need to reveal the
keys.
And right now, it’s going to use the same payment hash with all these nodes, which means that if somebody owns two of the nodes in the path, they are learning info, and that is unhealthy for privateness. Right now, everytime you ship a fee, this fee goes to go through a number of nodes on the network. Bastien Teinturier: Sure. So right now, when we introduced the channel on the community, we explicitly introduced node IDs and the Bitcoin keys that are contained in the multisig 2-of-2, and folks verified that the output that we are referencing is definitelyscriptd with the script hash of multisig 2-of-2 of these two keys, so you possibly can soscriptse it with scripts that basically 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 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.
