Bitcoin Forum

Hey everyone,

I'm doing a little side project where I am mapping the bitcoin blockchain to a graph database in order to both visualize the fundamental structure of the blockchain as well as explore the weakness in the anonymity of it as described by Satoshi's Paper Sec.10 on privacy using the connected components algorithm http://en.wikipedia.org/wiki/Connected_component_(graph_theory) (http://en.wikipedia.org/wiki/Connected_component_(graph_theory)).  Here is a just a quick screenshot of what I have so far: http://img803.imageshack.us/img803/9550/imagerv.png (Apologies for imageshack.. imgur is blocked for me)

The application I am using is querying the blockchain.info API, but as many of you are probably aware, it rate limits pretty strictly.  A query every two seconds will still result in a 503.   I was wondering if someone has an archive of the entire blockchain JSON form this API, or at least a sizable portion of it.  I chose to use this site instead of getting the information straight out of the blockchain because I enjoy some of the derived data they include.  

Do you guys have any suggestions where I can get the entire blockhain JSON archive?  Thanks in advance.

It's Berkeley instead of JSON, but why not just use the actual blockchain?
