Then you give up the privacy that eCash offers

I am really interested to learn eNut or eCash as I'm pro privacy. But I find myself confused with this model. You wrap the SATs and deliver them as eNuts/eCash? The receiver unwrap the SATs?

ecash (at least as currently implemented) is an IOU note issued by the mint. Usually it's denominated in sats but both fedi and cashu can in principle support fiat denominations. Fedimints are connected to LN through a gateway that exchanges between ecash and LN sats. For cashu mints, the mint itself is the gateway.

Fedimints are communities on Fedi? (is that correct?)

So, I would need to trust them, then?

Is there a map or something, because this isn't registering in my thick skull. Also, I don't understand ecash, fedimints, cashu mints, mints. I only understand Fedi is an app. This really seems like a pain in the ass to learn compared to XMR. Which is excessively easier than what you're describing to me as they use RingCT 16.

Ecash is money as a piece of text that you can just copy and paste or transmit with a QR-code or with a private message or however you want. It's a bearer asset: you have the piece of text = you have money. Usually ecash is an IOU but European Union plans to issue euros as ecash as well.

Mint is anything that issues ecash. It's the job of the mint to prevent double spending. When you receive ecash, you need to contact the mint to make sure it wasn't already spent. If it wasn't, you get fresh ecash of the same value. If you want, the old coin is melt and a new coin is minted, hence the name.

Fedimint is the software for running a mint as a group. A group mint running fedimint is also called fedimint because "fedimint-running mint" sounds stupid. Cashu is the software for running a solo mint. Fedi is the app to use fedimints.

Which is excessively easier than what you're describing to me as they use RingCT 16.

Can't agree here. Fedi is very user-friendly. In comparison, XMR mobile wallets need you to sync the chain all the time. With ecash you can push money: "here, scan this, here's 1k sats for you" but with XMR you can only pull ("give me your address so I can send you some piconeros"). Mint transactions are final in seconds, there's no waiting for the next blocks to confirm.

Okay, I'm going to repeat this by saying it out loud so I can comprehend it. I'll update you when I get it

That's not what I meant. You use ecash but there's a gateway. You go to a vendor and pay with LN through the gateway. The vendor might receive it in ecash through the mint he trusts or can just use LN directly, you don't care.

This works in cashu/fedi already. The gateway doesn't have to know who you are. The part where you give up privacy is the chat: your Fedi client connects to the chat server(s) asking "any dms for nullcount?" when you open your wallet.
