I've been working on a platform dedicated to the analysis of the bitcoin blockchain. The first application built on top of this plateform is OXT (the Other eXploration Tool).

OXT provides a set of statistics & interactive visual tools easing the exploration of the blockchain (interactive charts for drill down/filtering, transactions graph visualizer, ...).

In addition, OXT computes a set of privacy-oriented metrics (address reuse, entropy of transactions, link probability between uxtos, temporal patterns of activity...) and uses a few heuristics allowing to cluster addresses controlled by a same entity.

The project is at an early stage but I hope its first features will be useful to the community. Feel free to send your feedback & suggestions !

Last but not least, OXT supports the Open Bitcoin Privacy Project in its mission to improve financial privacy within the Bitcoin ecosystem.
