Bitcoin Hopes and Dreams
본문
So now we all know the entire means of bitcoin functioning and how Bitcoins can be utilized for making all sorts of real transactions. Bitcoins are exchangeable for fiat forex via cryptocurrency exchanges and can be used to make purchases from merchants and retailers that accept them. Greg Sanders: Yeah, if I can soar in. Mark Erhardt: So I’m questioning, one among the problems that appears to jump out once i hear you speaking 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 version first and watch for later to do a much more advanced version, or if we should just leap to the extra advanced version proper now. Because we’ve all the time been discussing the fact that saying, having the channel announcement point to a selected onchain output, was quite dangerous for privateness and that we could probably do better. So, those are issues that we’ve at all times been just hand-wavy about how we would try this sooner or later.

But I don’t suppose we’ll let you have any form of multiplier, as a result of one in all the other ideas was that you would additionally simply announce some UTXOs that you personal, with the proof that you own them, with a total worth of, for instance, 2 bitcoin, after which that will grant you the flexibility to announce up to X occasions that in channels without having to point to any particular onchain output. I didn’t think it was too bad, but the one key distinction here is that for the fee channels with penalties as currently designed, it’s necessitating that you just retailer these secret nonces perpetually till channel shut. These charts are cardinal part of the whole affair as with them traders are able to foretell the motion near accuracy. But, understanding that the markets by no means shut is a useful safeguard to have. If you have one other Lightning-like channel specification that you coded up or a custom channel type, you can too include that in this channel announcement and it will simply work. That’s why we’re not doing that proper now, and that’s why most individuals will just keep asserting the output that really corresponds to the channel so that when it will get spent, folks really discover it and can take away it from that graph and know that they can not route by means of that channel anymore.
I think we’re going to keep on with a easy model, where you permit pointing to any type of output to pay on your channel. PTLC fixes that by making sure that instead of using 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 on condition that BIP32 already supplies extended personal keys (xprvs) that may be shared between signing wallets. Maybe we are able to start with t-bast. Can the channel stay open when the UTXO gets spent? And however, 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 retaining track of the UTXO truly not being moved whereas 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 dialogue and how gossip protocol would should be upgraded as a way to help moving to P2TR outputs. So, we want to change that, because we'd like to permit taproot, which means allowing also enter, especially if we use MuSig2; we don’t want to reveal the inner keys.
And proper now, it’s going to use the identical cost hash with all these nodes, which implies that if somebody owns two of the nodes in the trail, they're learning info, and this is unhealthy for privateness. Right visit Youtu now >>>, everytime you send a fee, this cost is going to undergo multiple nodes on the network. Bastien Teinturier: Sure. So proper now, once we announced the channel on the community, we explicitly introduced node IDs and the Bitcoin keys that are inside the multisig 2-of-2, and other people 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 possibly can solely use 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 ahead, Murch. Mike Schmidt: Next section from the Summit mentioned PTLCs and redundant overpayments. Bastien Teinturier: Okay, so PTLCs are a change that's allowed by taproot and adaptor signatures.
