I tested several third party app stores. But found direct download of the APK from https://stashpay.me had the best UX. The APK is signed with the developer key. So it‘s a TOFU (trust on first use) model if you trust the TLS cert on the first install. Subsequent updates of the APK would verify the developer signing key.
What‘s the advantage of using third party app stores? They don’t do auto-updates as far as I understand?

Spent the last four days off the grid in the Austrian Alps. Being able to unplug when I need a break is my favorite part of going indie. The main pressure I have to manage is from myself. It‘s been great to let go and hang out in the mountains with old friends for a few days.
This Monday feels totally different than last week. I’m excited to hopefully be able to invite the first StashPay users to TestFlight soon. But I feel rested and have accepted there are things I cannot control. App Store developer KYC is one of them.

Appreciate your message and apology. No offense taken. I’m just expressing a trend I’ve been observing on Nostr and in Bitcoin. And yes, we need to meet people where they’re at. Change happens slowly. Anyway thanks again and enjoy your Sunday 🙏🏼

2024-09-08 14:45:44

Unpopular opinion: Nostr users and influencers aren’t doing themselves a favor with the constant purity tests and true scotsmanship. It just alienates anyone trying to start a business.
Yes, the KYC on X suck, but it’s still the best way to build a marketing funnel and build traction. I’m trying my best to leverage Nostr and learn what its strengths/weeknesses are as a marketing tool, but first impression is it’s a mixed bag. Conversation with an experienced marketing person who was kind enough to mentor me this week confirmed that. I’m open to constructive feedback and suggestions as to what I’m missing though.
And yes, a newsletter sucks. But email is still one of the best ways to communicate with customers. If used wisely it’s a powerful tool and can be valuable for both sides.
And yes, Apple’s monopoly sucks. But iOS users still pay the most for software. Android users simply don’t pay for apps and buy subscriptions as much. I hope Zapstore offers new models to monetize Android (and AOSP) and I will keep shilling it because of that.
But if you aren’t offering solutions to these problem and just dunking on people doing their best to build something, you’re honestly just part of the problem. #note1z8l…60fz

FWIW I would personally trust the Liquid Network over a bank any day, especially for payments. But anyone can make that decision for themselves and their business.
Don’t forget as a US citizen you are speaking from a position of privilege. There is an underserved market that can’t get a bank account easily. Digital nomads and global small businesses is one of them. As a “foreign resident alien” (or whatever the IRS calls me) it’s hard to get a business bank account for my LLC. US banks see you as a compliance risk, not worth their time. So I have to use fintechs like Wise that don’t offer FDIC insurance. I’ll def take Liquid over holding any funds there.

2024-09-04 09:47:26

I think it might be useful distinguish between multiple use cases and threat models for Bitcoin as a medium-of-exchange and acknowledge that these are being served by different architectures.
1. C-2-C payments
2. B-2-B payments
3. B-2-C payments
It seems to me 1. requires trust-minimization and high privacy. This use case is currently being served by LSP based self-custody Lightning wallets. And also by Cashu/Fedimint though these do leverage local trust and social incentives to share UTXOs.
For 2. and also in partially for 3. I think federations like Liquid leverage trust between businesses. So not on a local/private level but on a corporate level. Trust relationships in business can also be viewed as a type of social inventive structure to scale UTXOs but these are more abstract. So it makes sense that these federations have more members and I hope we will see more than one competing with each other.
I’m still wrapping my head around Liquid, so I need to give this more thought. But it seems useful to reason about it that way.

Your first assumption is correct. The funds are received and held by the user‘s liquid wallet on their phone. There is no lightning node on the device, so no need to manage inbound liquidity. Boltz handles all of that.

Re 1. yeah the idea is focus on receiving first. Will see where that journey takes me and add features customers ask for.
Re 2. a valuable service is also what I want to build. StashPay users will always be able to export their BIP39 seed and move to any other wallet that builds on the Liquid SDK. Keeps me honest.

We are all blind to hypocrisy without the people around us keeping us honest. May we keep friends close that call us on our bullshit. It stings in the moment, but it protects us from our ego in the longterm.
#Nostr and #Bitcoin are technical manifestations of that check on the ego. They’re imperfect, but the best protocols we currently have in a world that has become unhinged. May the transition be peaceful.

Batching makes sense for pleb nodes. I am mostly interested in mobile, yes. I’m trying to keep an open mind re self-custody mobile Lightning. Though I suspect mobile wallets will start adopting more federated subnets like Liquid and Fedimint. The trust trade-off makes a lot of sense to lower liquidity needs and fees for end user payments.
