So now we know the entire means of bitcoin functioning and the way Bitcoins can be used for making all types of actual transactions. Bitcoins are exchangeable for fiat forex via cryptocurrency exchanges and can be utilized to make purchases from merchants and retailers that accept them. Greg Sanders: Yeah, if I can leap in. Mark Erhardt: So I’m questioning, one in every of the problems that appears to leap out when i hear you speaking about this is, what if one aspect keeps making updates however not concluding it? And we’ve at all times gone back and forth between those, because we don’t know if we should always do a easier version first and anticipate later to do a much more complex version, or if we should always simply jump to the more complicated version proper now. Because we’ve always been discussing the fact that saying, having the channel announcement level to a particular onchain output, was fairly unhealthy for privateness and that we may probably do better. So, those are issues that we’ve all the time been just hand-wavy about how we might try this in the future.

But I don’t assume we’ll assist you to have any kind of multiplier, because one in all the other ideas was that you can additionally simply announce some UTXOs that you personal, with the proof that you simply own them, with a complete worth of, for example, 2 bitcoin, after which that would grant you the flexibility to announce as much as X instances that in channels with out having to level to any specific onchain output. I didn’t think it was too unhealthy, but the one key distinction right here is that for the payment channels with penalties as at the moment designed, it’s necessitating that you just retailer these secret nonces endlessly till channel shut. These charts are cardinal a part of the entire affair as with them traders are able to predict the movement close to accuracy. But, knowing that the markets by no means close is a useful safeguard to have. When you have another Lightning-like channel specification that you simply coded up or a customized channel kind, it's also possible to include that in 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 just keep saying the output that really corresponds to the channel in order that when it gets spent, people truly notice it and may take away it from that graph and know that they cannot route through that channel
more.
I feel we’re going to stick with a simple version, where you permit pointing to any sort of output to pay in your channel. PTLC fixes that by ensuring that instead of using the preimage of a SHA256 hash and its hash, we’re going to use elliptic curve factors and their non-public keys. This may seem pointless provided that BIP32 already provides prolonged personal keys (xprvs) that can be shared between signing wallets. Maybe we are able to begin with t-bast. Can the channel stay open when the UTXO gets spent? And alternatively, how do you make sure that the same UTXO is not 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 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 https://youtu.be/xxdm7aeP-9g the way gossip protocol would must be upgraded to be able to help transferring to P2TR outputs. So, we want to change that, as a result of we'd like to permit taproot, which means allowing also input, particularly if we use MuSig2; we don’t wish to reveal the in
or keys.
And right now, it’s going to use the same payment hash with all these nodes, which signifies that if someone owns two of the nodes in the path, they are studying data, and this is dangerous for privacy. Right now, whenever you send a cost, this fee is going to go through multiple nodes on the community. Bastien Teinturier: Sure. So right now, once we introduced 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 folks verified that the output that we're 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 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 part from the Summit discussed PTLCs and redundant overpayments. Bastien Teinturier: Okay, so PTLCs are a change that is allowed by taproot and adaptor signatures.
