So now we all know the entire process of bitcoin functioning and the way Bitcoins can be used for making all sorts of actual transactions. Bitcoins are exchangeable for fiat forex via cryptocurrency exchanges and can be utilized to make purchases from merchants and retailers that settle for them. Greg Sanders: Yeah, if I can jump in. Mark Erhardt: So I’m wondering, one of the problems that appears to leap out after i hear you speaking about that is, what if one aspect keeps making updates however not concluding it? And we’ve at all times gone again and forth between those, because we don’t know if we should always do a easier model first and watch for later to do a way more complex version, or if we must always just soar to the extra complicated version proper now. Because we’ve always been discussing the truth that saying, having the channel announcement level to a particular onchain output, was fairly bad for privacy and that we might probably do higher. So, those are issues that we’ve always been simply hand-wavy about how we'd do that in the future. Read More: Amid value drops and increased regulation, what’s the way forward for cryptocurrenc

But I don’t think we’ll allow you to have any form of multiplier, because considered one of the other concepts was that you possibly can also just announce some UTXOs that you personal, with the proof that you simply own them, with a total value of, for instance, 2 bitcoin, after which that may grant you the flexibility to announce up to X instances that in channels with out having to point to any particular onchain output. I didn’t assume it was too dangerous, however the one key distinction right here is that for the fee channels with penalties as presently designed, it’s necessitating that you just retailer these secret nonces ceaselessly until channel shut. These charts are cardinal part of the entire affair as with them traders are able to foretell the movement close to accuracy. But, realizing that the markets never close is a helpful safeguard to have. If you have one other Lightning-like channel specification that you just coded up or a custom channel sort, you too can include that in this channel announcement and it will just work. That’s why we’re not doing that right now, and that’s why most people will simply keep announcing the output that basically corresponds to the channel in order that when it will get spent, people really discover it and can remove it from that graph and know that they cannot route by that channel
re.

I think we’re going to stick to a easy version, where you permit pointing to any kind 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 points and their non-public keys. This may seem unnecessary on condition that BIP32 already supplies prolonged non-public keys (xprvs) that may be shared between signing wallets. Maybe we will start with t-bast. Can the channel stay open when the UTXO will get spent? And then again, how do you make sure that the same UTXO will not be reused for the announcement; and what happens if that UTXO will get spent? So, will we must be preserving monitor of the UTXO really not being moved whereas it's the stand-in to have introduced the channel? Mike Schmidt: The taproot and MuSig2 channel dialogue somewhat leads into the updated channel announcement discussion and how gossip protocol would should be upgraded as a way to help shifting to P2TR outputs. So, we want to change that, as a result of we'd like to allow taproot, which suggests allowing additionally input, especially if we use MuSig2; we don’t want to reveal the in
keys.

And proper now, it’s going to use the identical payment hash with all these nodes, which signifies that if someone owns two of the nodes in the trail, they're studying information, and this is unhealthy for privacy. Right now, https://youtu.be/lOpBbBQIqug everytime you send a payment, this cost is going to go through multiple nodes on the community. Bastien Teinturier: Sure. So right now, when we introduced the channel on the community, we explicitly introduced node IDs and the Bitcoin keys which might be inside 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 really observe the format of Lightning channels with out taproot. Mike Schmidt: Murch or t-bast, any 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.
