(And No, I Don’t Believe in Creationism)

I think we are alone in the Universe.

Many people will argue that, given the sheer size of our galaxy — let alone the observable universe — and the estimated high number of life supporting planets, it’s a near impossibility that there is no other life out there.

That’s an exciting prospect and I was arguing the same way in the past, but I’ve changed my mind.

The reason I changed my mind is the following: As mind-blowingly enormous the observable universe and even our galaxy alone might be, probabilities for the occurrence of possible events can be just as…


There are situations in which you either want — or are required — to store data in a way that allows to unequivocally prove when exactly this data has been stored or altered.

In this article I will explain what RFC3161 timestamps are and what problem they solve, and will then go on to explain why Git™ provides the perfect architecture to be used together with such timestamps in order to create a tamperproof data repository that can provide the following properties:

  • Authenticity: trusted, non-refutable time when data was added or changed
  • Integrity: protection of the timestamped data as well…

Thank you Thomas for reading my article and for your feedback, it is appreciated!

In fact, I created GitTrustedTimestamps exactly for the purpose of having a data archive that conforms to GeBüV requirements.

AFAIK, there is no such thing as an officially recognized (or required) GeBüV certificate.

However, there are private companies that perform an audit and issue such certifications in order to give firms which implement or use such an archive (either in-house or as product) confidence that their solution corresponds to GeBüV (and other) requirements, by providing a 3rd-party expert opinion.

I'm currently in the evaluation process of getting such a certification for this open-source solution.

Any expert input on the matter is highly welcome, so please don't hold back! :)
