|    Everytime I zap someone vie Lightning from my wallet, it takes 5-10 seconds for the zap to settle and for
|    everyone to see it happen on nostr.
|    
|    Everytime, I think "this could've been an instant nutzap". "Tap, boom. Tap, boom. Zap zap zap. I would be
|    zapping so much more."
|    
|    The reason a nutzap is instant is obvious. At this point, I hope that everyone knows that a Cashu nutzap is just
|    an instant transfer of an IOU from one user to another.
|    
|    Let's step back and look at a pure Lightning zap on nostr for a second. We all know that the vast majority of
|    Lightning zaps is effectively an exchange of one custodial IOU against another one as well. Most people use
|    custodial wallets. So why is it still so slow? It's the Lightning settlement between the two custodians that
|    often takes 5-10s to complete. Note, some users actually do run their own node, manage channels, run LNURL
|    servers, etc. But they still get the same UX.
|    
|    Here is an idea. Let's say a user doesn't want to use Cashu. Pure Lighting maxi which I think is great. I've
|    been a Lightning dev for years before I started working on Cashu. This user could still be nutzapped and even
|    remain fully self-sovereign if they run their own node.
|    
|    What if the receiving user's Lightning wallet (custodial or non-custodial) was able to melt all nutzaps it
|    receives by watching the nostr wallet ("nutsack") of its user? Either for every nutzap or whenever enough nuts
|    are accumulated, the service could withdraw the nuts to the user's real Lightning wallet.
|    
|    Effectively, this would improve the zap UX by showing everyone an instant zaps. The receiving user's custodian
|    (or themselves) would have to run something like a nostr-cashu-wallet-watcher on a server to receive while being
|    offline, but they have to run a Lightning node and LNURL and all that anyway (they already have a server).
|    
|    Even without a server, normal nostr clients without true nutzap support could withdraw all nuts accumulated
|    while they were offline back to their Lightning wallet everytime they come back online. The only real difference
|    to a normal zap is that noe it's the receiver's job to settle via Lightning, not the zap sender's.
|    
|    Nevertheless, zaps on permissionless social media like in nostr will never be completely trustless. They can't
|    solve the sybil problem for instance. If you want, you can zap yourself an infinite amount of normal Lightning
|    zaps on nostr without moving s single Satoshi. We faked zaps in the early days like crazy just to have fun.
|    
|    But it actually turns out, all that doesn't really matter too much at all. First, people seem not to abuse the
|    sybil issue. We had fun for a few weeks but then it got uninteresting There is not enough to gain, no algorithm
|    to fool, no benefit of lying (at least not yet). Second, zaps are literally free money given to you from a
|    random person. Why would someone rug you if they want to literally gift you money? It doesn't make much sense.
|    
|    I think we have a lot more to learn. @PABLOF7z recently said he thinks we have explored 1% of what zaps can be.
|    He might be right. I think the reordering of events that a bearer zap system like with Cashu brings could open
|    new doors for insane UX and it looks like we're actually going to find out. We have zero-config wallets now.
|    Imagine how cool it is to bring your money wherever you go with your nsec.
|    
|    Keep exploring, cypherpunks. We do live in the best of all times. Bullish on Bitcoin, bullish on Nostr, bullish
|    on Cashu 🧡
