Today, we’re announcing Vulpem Notary, a blockchain-based notary service specifically tailored for enterprise workflows and distributed architectures.

We have created an abstraction layer that we offer as a cloud service, which helps database operators to create an indisputable chain of events that happened in the private infrastructure, without leaking any sensible information.

In this way, any observer can easily audit and verify any possible malicious attempt of tampering, both from an external attacker or an inside job and be able to demonstrate it ex-post.

This allows to cryptographically prove to other parties (eg. auditors or consortium partners) that some data existed prior a certain point in time.

How does it work?

We provide a lightweight and standalone client, that can be easily installed on the majors cloud platforms, which oversees the low-level replication of the distributed database cluster (MySql and MongoDB are supported for now) and takes care to split, makes a one-way fingerprint, timestamp, and queue for a public and indisputable attestation.
Thanks to batching and distributed calendar architecture, we can stamp and notarize petabytes of data and embed them on the Bitcoin blockchain.


In any centralized architecture that implies a database, the person with admin privileges (the owner, employees, contractors) can simply delete or modify any data stored in it and no-one, even with the help of modern digital forensics tools, can demonstrate to an external viewer without any doubts that this malicious action has happened.

While this concern seems to be solved for the enterprises by “private blockchains” or “distributed ledger technology”, we believe that Vulpem Notary is a more elegant, more scalable and friction-less solution using open time-stamping technology on top of Bitcoin, acting as a neutral notary.

There is no need to move any data to a new architecture and scrap your existent systems, just get an API key, install the daemon and you are ready to go! The same guarantees of so-called private-blockchains, without changing any lines of code!

Lastly, the number of features, years or even decades of extensive testing and reliability of a common distributed database isn’t comparable to any of the primordial private blockchain solutions like Hyperledger and such.
