I propose removing the `description_hash` requirement from zaps as many have already started doing so with bare LNURL-pay. I know that many nostr client devs haven't even checked this from `zap receipts` to begin with – your laziness was worth it! Nostr client and zap server devs: What are your thoughts? Please give feedback in the PR 🙏

Gm Lightning devs! Time to remove code: let's drop the metadata validation in LNURL-pay! Test your wallet by zapping my LNbits running with BreezSDK on Greenlight. CLN doesn't like description_hash. ⚡️ zap@legend.8333.space Can you pay this LN address?

We're close to merging DLEQ proofs for Cashu This was a loooooong journey as you can see it's the oldest open PR in the repo :) We've come up with 2 different schemes that could've replaced this DLEQ proof but none of them is so significantly better that they could replace it. In short: the DLEQ proof is additional data that is attached to the ecash token that allows a receiver to verify the mint's signature given the mint's public key without having to talk to the mint It sounds trivial as for most signature schemes, this is easily possible without adding other stuff (you can just verify the signature, that's it). Why do we need this? It's a necessary building block for our evil plan of implementing ecash zaps on nostr and other cool things like offline receive.
