Nice illustration!

Zapped you but looks like wos slept on it.

Did it show up by any chance (100sats) on your side?

Yes! We just cracked another nut in Cashu's protocol development: How to handle Lightning's unpredictable fees with no additional rounds of communication?

This was one of the weakest points of the protocol.

Background: https://gist.github.com/callebtc/a6cc0bd2b6f70e081e478147c40fc578

Proof of concept:

## Very short summary of the problem

In Lightning, you don't know the fee in advance. But in ecash, you need to pay for everything upfront (ecash isn't divisible, the mint can't simply return the change back to the user when they overpay Lightning fees).

Solution: The wallet provides a set of "blank outputs" (blinded secrets) when asking a mint to make a Lightning payment.

The blank outputs don't have an amount but the mint can "imprint" amounts in them and return blind signatures (= ecash) to the wallet if they overpaid fees.

This is beautiful. We sat down in a virtual circle (thank you phyro, #[0] ) and thought hard about possible solutions and discovered this.

Unpredictable LN fees and backups were the two big issues in Cashu's protocol design and now we fixed both! 🎉

Trying to understand cashu. Anyway to give a try to this in my own CLN or LND based lightning node?

Can you direct me to the payload that makes up the NIP-57 zapping? Thinking about something big. Like the big zap ⚡

Not sure how we can wake up the normies 🤔

Actually Bitcoin developers can sue him for defamation. They are likely to win the case with huge sums to be paid to each of them.

Here is how he is defaming them as a response to my tweet:

#[5]

He is dragging Bitcoin developers to lawsuits in different countries so that he can push them to quit developing for Bitcoin.

Here is my tweet that made faketoshi to block me today. He knows what he deserves at least.

Definitely! Trying to pass this info to newcomers as much as possible.

👋 yes, I have no spam on my global Amethyst feed with global (and public chat) limited to paid nodes.

Hopefully the first zap of your day to hold it up ⚡ 💜 🧡
