Is it possible to download all blockchain raw data? I'm interested in doing some analysis on the blockchain that would require specific information about all individual transactions within each block. I don't need the data to be updating in real-time, but I am looking for something that at least encompasses all the transactions made in the past year. I've tried to find downloads for this kind of dataset, but I haven't had any luck. Any ideas?
Any (full) Bitcoin client will download the entire blockchain. It's stored in files on disk which you can look at after it's been downloaded. The current blockchain size is 115 GB of raw data (the size on disk will be a bit larger because of indexes created by the client).
