You can download the dataset in plain text (TSV) format below.


Original dataset, 2.8 GiB + 1.3 GiB The data used in our two papers, includes the list of all transactions up to 2013.12.28, presented here for historical purposes.
New dataset, 11.7 GiBWhole blockchain up to 2016.02.09. (397,571 blocks).
User graph contraction, 435 MiB Identification of addresses which probably belong to the same entities in the new dataset (using the method for matching addresses which appear together as transaction inputs as described in our first paper).
Transaction graph, 2.1 GiBEdges linking individual transaction outputs to transaction inputs when they are spent next for the new dataset (i.e. a reconstruction of the "flow" of bitcoins).
READMEDatafile descriptions for the new dataset
Timestamped graph of most active users, 105 MiBThe graphs used in our New Journal of Physics article, created using the "original dataset".
