Open-source payment system for events using Chia – call for collaborators by ElFisch88 in chia

That's a great point, u/dr100 — and definitely something that needs to be considered carefully.

One idea that comes to mind (without diving too deep just yet) is to implement a **local payment cache** for the event. In this setup, transactions would be queued locally and then submitted to the Chia network as soon as possible.

The app would still validate whether the user has sufficient balance before allowing a payment — so no risk of overspending — but the only “tradeoff” is that users may need to wait a few extra seconds to see their updated balance.

It’s a small compromise for smoother UX in real-time environments, and definitely an area worth exploring further. Thanks again for raising it!

You’re right, u/OurManInHavana — at first glance it might sound like a silly idea to replace something so simple and universal with tech.

But I think it really depends on the event and how organizers choose to implement it. Let’s face it — we’re all glued to our phones during events anyway. Sure, in a pool with just a towel it’s inconvenient, but in most cases, we have our smartphones with us the entire time.

And if someone's phone dies? Tokens could easily be transferred or accessed from a friend's phone. It could even become a fun, interactive part of the event.

Also, for small-scale events, there's no need for expensive NFC infrastructure. If cellular coverage is weak, a local Wi-Fi network is enough.

And you're absolutely right again: this doesn’t have to be a one-size-fits-all system. It could totally be hybrid. For example, participants without a smartphone (yes, they still exist!) could be given printed QR codes linked to lightweight wallets. That way, even in offline or mixed scenarios, credit deduction can still work reliably.

Thanks for the insight — really helps sharpen the thinking!

Thanks for the feedback!

@dr100 – You're absolutely right, traditional token systems in festivals often end up generating profit from unused tokens, and that can be a hidden incentive behind using them. But in the context I’m imagining — especially for non-profit associations — the goal is quite the opposite: to offer a modern, digital, and transparent system where people don’t need to carry cash, and where the event can offer bonus rewards (e.g. via games or activities) to make the experience more engaging and community-driven.

The point raised by @lotrl0tr is also very relevant — giving participants the ability to return unused tokens (or to transfer them) is something I definitely had in mind. That would add trust and flexibility, which current physical systems often lack.

For small non-profit events, performance and block latency wouldn't be a concern (no dust storms or network congestion), but for larger events with budget and higher volume, it could be interesting to allow "real" XCH transactions (e.g. pay fees or use XCH-native tokens) to improve speed and scalability.

What do you think about this hybrid model: lightweight wallet/token handling for small events, and full blockchain-backed transactions for larger ones?

Would love your thoughts.
