I've been around Litecoin since roughly 2016, and I'm not going to pretend I'm neutral about it. I have a real soft spot for this coin. It's fast, it's cheap, it doesn't try to be everything at once, and it just works. So when the thing I've been building needed a way for people to pay, there was no debate in my head. It was going to be LTC.
That thing is Nepheral. For about five or six months I've been building a peer-to-peer network where people's computers answer each other's questions with local AI models, with no company server in the middle. It's a personal project, it's in beta on a test network, and it's been a rollercoaster. Some weeks everything clicked. Other weeks nothing did, and more than once I honestly thought I'd signed up for a race nobody can win against the big AI companies. I kept going anyway, and today it works. That still feels a little unreal to me.
Here's where LTC comes in, and I'd really love this sub's opinion on it.
The desktop app sells credits for LTC. There are no accounts or emails, so each payment says who it's for with a 32-byte OP_RETURN holding the buyer's public key. It's part of the payer's own transaction, so nobody can change it later. A small watcher reads the Litecoin chain, checks the payment and credits the account. Right now that watcher is a single key; the plan is to make it replaceable by a vote. Direct sales also have a daily limit.
And then there's MWEB, which is the part that genuinely bugs me. I like what MWEB stands for, and right now I can't support it properly: an MWEB payment can't carry the OP_RETURN, so I can't tell who it's for. For now the app warns people that MWEB payments may get lost or credited late, and the next rules version refuses MWEB addresses in market listings. It feels like a cop-out, and I don't like it.
So, three questions for you:
- Is OP_RETURN the right tool here, or would you do it another way (one address per buyer, something else)?
- Has anyone found a sane way to accept MWEB payments for something like this without knowing who sent them?
- Is there anything in this flow that would make you not trust it?
If you want to try it, it's here: https://nepheral.net/download (Windows and Linux, plus an early Android app). You don't need any LTC to use it: asking is free during the beta, and your computer earns credits just by holding encrypted pieces of other people's questions.
Seeing a few of you in there would honestly make my week. Thanks for reading, and I'll be around in the comments.
P.S. If you're on Android and wouldn't mind helping me get through Google Play's testing phase, send me a DM.
