Part of being a human is wanting to leave a mark on the world. Within us lies the deep need to be remembered, in some form, after we die. We see it in the Cueva de las Manos - Cave of the Hands, where the inhabitants left the outlines of their hands painted on the walls as early as 13'000 years ago.
Cave of the Hands
We hear the same plight from Horace some 2000 years ago in his Odes when he states "non omnis moriar" - "not all of me will die". Similarly, to condemn someone to be forgotten was a fate worse than death for the ancient Romans. It was called damnatio memoriae, or "the condemnation of memory".
In our digital age it is perhaps easier than ever to remove someone from history. While it is easier than ever to record what's going on, it is similarly just as easy to alter and distort the events thanks to tools like Photoshop.
Photos can be altered, memories can be called into question, records could be rewritten, and we can end up with the Mandela Effect. Add to it the right to be forgotten, and soon it might be hard to believe any record or lack of it on the Internet. George Orwell would be proud of what we could do to make someone an unperson.
Everything could be subject to change. Everything that is, except blockchains.Proof of Existence
While working at Factom I heard a great tagline - "It is hard to guess today what lie you want to tell tomorrow". It might be a very profound statement in today's world of digital records - if you can't backdate, alter historical records or the like, you'd better be completely sure how you want to proceed ahead of time.
All of this is of course only possible through the Proof of Existence and the blockchain technology. Only networks such as Bitcoin or Ethereum can be seen as objective records of history anymore. They alone are big enough to be secure from tampering (if you can't 51% attack the blockchain, you can't rewrite the history) and public enough to en...
