I just need to vent, I got scammed
Write down everything you remember while it is still fresh, including all BTC addresses. You can even store a hash of your notes in the blockchain as proof of existence. Source: about 1 year ago
Is it safe to develop a video game with online strangers? Is there a best practise to protect my work?
If that's not enough, you could publish a hash. Proof of Existence is a service that adds it to the blockchain so you can always prove it, but realistically that's overkill and I'm sure sticking it on Google Drive would be enough. Source: over 1 year ago
Proof of Existence app
Bitcoin has proofofexistence.com. It hashes a file via the browser and stores the result in OP_RETURN. The current fee is around $7, which is no longer practical. Source: almost 2 years ago
Including a newspaper front page in a photo can prove that the photo was not taken prior to a certain date, but is there any way to prove a photo was not taken *after* a certain date?
Proof Of Existence is a service for this. You take the hash of the photo, then when you're picking random numbers to mine bitcoin, pick numbers that start with that. Once you've successfully mined a block, that number will be stored in the blockchain. Source: over 2 years ago
