So now we all know the whole process of bitcoin functioning and how Bitcoins can be utilized for making all kinds of actual transactions. Bitcoins are exchangeable for fiat forex by way of cryptocurrency exchanges and can be used to make purchases from merchants and retailers that settle for them. Greg Sanders: Yeah, if I can leap in. Mark Erhardt: So I’m wondering, one in every of the problems that appears to jump out when i hear you talking about that is, what if one aspect keeps making updates however not concluding it? And we’ve always gone again and forth between these, because we don’t know if we should do a simpler model first and await later to do a much more complicated version, or if we should always simply leap to the extra advanced version proper now. Because we’ve at all times been discussing the fact that announcing, having the channel announcement point to a specific onchain output, was fairly bad for privacy and that we may in all probability do higher. So, those are things that we’ve at all times been simply hand-wavy about how we'd do this in the future. Read More: Amid value drops and increased regulation, what’s the future of cryptocurrency?

But I don’t assume we’ll permit you to have any sort of multiplier, as a result of certainly one of the other ideas was that you may additionally just announce some UTXOs that you just personal, with the proof that you simply own them, with a total value of, https://youtu.be for example, 2 bitcoin, after which that will grant you the ability to announce up to X occasions that in channels without having to level to any particular onchain output. I didn’t assume it was too dangerous, however the one key difference here is that for the payment channels with penalties as at the moment designed, it’s necessitating that you retailer these secret nonces without end until channel close. These charts are cardinal a part of the whole affair as with them traders are ready to foretell the movement near accuracy. But, figuring out that the markets by no means close is a useful safeguard to have. If in case you have another Lightning-like channel specification that you simply coded up or a customized channel sort, you too can embody 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 individuals will just keep announcing the output that really corresponds to the channel in order that when it will get spent, individuals truly notice it and may remove it from that graph and know that they can't route by means of that channel anymore.

I feel we’re going to follow a simple version, where you permit pointing to any type of output to pay for your channel. PTLC fixes that by ensuring that as a substitute of utilizing the preimage of a SHA256 hash and its hash, we’re going to use elliptic curve points and their personal keys. This may seem pointless on condition that BIP32 already provides extended private keys (xprvs) that may 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 however, how do you guantee that the identical UTXO shouldn't be reused for the announcement; and what happens if that UTXO will get spent? So, will we must be maintaining monitor of the UTXO truly not being moved while it is the stand-in to have introduced the channel? Mike Schmidt: The taproot and MuSig2 channel discussion considerably leads into the up to date channel announcement discussion and the way gossip protocol would need to be upgraded in order to help moving to P2TR outputs. So, we'd like to alter that, as a result of we'd like to permit taproot, which implies allowing also enter, especially if we use MuSig2; we don’t need to reveal the internal keys.

And proper now, it’s going to use the identical cost hash with all these nodes, which signifies that if somebody owns two of the nodes in the trail, they're learning info, and that is bad for privacy. Right now, whenever you send a payment, this cost goes to go through a number of 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 might be inside the multisig 2-of-2, and folks verified that the output that we are referencing is definitely locked with the script hash of multisig 2-of-2 of those 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, any other comments on taproot and MuSig2 channels? Mike Schmidt: Go ahead, 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.
