This looks like a very promising product. Please try to put it on product-hunt as you need more exposure. Is it possible to set-up a full-fledged payment system using this full node? If I'm planning to start accepting bitcoin payments on my website, can I back up my wallets using this node?
Thank you for the positive input as well as the suggestion! We will post on product hunt in the coming days.
If youre talking about something like BTCPayServer, this is something we plan to integrate into future iterations of nimbleNODE made specifically for businesses/individuals looking to accept payments directly to their node. It's not currently possible to install on this first version of nimbleNODE as it only comes with a 16GB sd card. BTC + BTCPayServer w/Lightning takes a minimum of 80GB (their recommended minimum requirement) so this is something that will be built-in along with Lightning and fastsync in the next model on higher-end hardware.
Having said that, you can certainly still spin up a BTCPayServer separately and use the BTC nimbleNODE device to actually receive the payments. If you are running a business and accepting crypto, it is highly recommended to a run a full node regardless and nimble is a great option for this. This way, all keys/seed phrases are fully in your possession.
