Proof of Existence
The Blockchain has a wide range of utilities and additional uses. In fact, the disruptive potential of this technology is so great that it is bound to change the way how we keep record of things and many more. It can be applied to virtually everything.
One of these uses is the chance to immutably record any document into the known public distributed ledger – The Blockchain. Proof of existence (PoE) has been here for a while and has become a pretty handy tool when it comes to public proof and authenticity of any record or document because even today, an email or a signed message sometimes might not be enough to prove something.
