I am actually working on the whitepaper right now. Which I will be submitting my patent idea very shortly. To secure my idea on https://originstamp.com. Source: about 2 years ago
P.S. You should use OriginStamp or something similar to put the hash of the cafe transaction ID (a hash of a hash, I suppose) on a blockchain and tell us about it so that you can later prove that you did have a specific target transaction in mind. Otherwise, you could unfairly "change your mind" about the target transaction later. Source: over 2 years ago
2) To prove that your video or photo were collected no later than a certain date, you can hash the file and then post it to a blockchain, such as BTC or BCH. This service does that for you. I or others could help you do the technical parts. It shouldn't be too hard. Source: over 2 years ago
BCH is disabled as a payment method for coingate.com transactions. Support pages don't mention it, but even if I hypothetically wanted to try using Lightning Notwork, the limit is 0.042 BTC, have fun getting the actual BTC with a $20 fee🙄 https://support.coingate.com/hc/en-us/articles/4402506647314-What-is-the-Lightning-Network-limit-.

Although this migration took quite a while, since it needed a new UI re-design, there were some difficulties migrating to a separate WordPress hosting, because our main page (coingate.com) is built on react.js. Source: about 1 year ago
What about for paying for services such as VPNs or Domain Registrars? Many use CoinGate (https://coingate.com/). That's a cryptocurrency payment processor. So is BitPay. And so is Coinbase Commerce. Source: over 1 year ago
Coingate looked promising as well, but it looks like they use a supervised wallet rather than your own. Source: over 1 year ago
There is another service called - https://coingate.com but I haven't used them before. I came across it after some searches. However, since Bitrefill has a very extensive selection you may end up just using it. Source: about 2 years ago
