I had an idea the other day to download a backup of my LinkedIN data. It includes conversations, posts I’ve made, contacts along with most of their email addresses. Of course it contains lots of business development conversations where I spoke to people about the ideas I have for RemedyCoin. Of course I want to be able to demonstrate that the ideas are mine and that I have been telling people about them. What better way, than to register the whole zip file LinkedIn gave me on the blockchain with ProofOfExistence.com. So for about $5 usd worth of Bitcoin I was able to make this happen. The BitcoinCash network also has this feature at notary.bitcoin.com for only about 60 cents.
What do you think? What else can we do with Proof of Existence on a blockchain?
