Structure and Dynamics of the Bitcoin Transaction Graph — •Kay Hamacher — Depts. of Physics, Computer Science, and Biology, TU Darmstadt

Bitcoin is a decentralized, digital currency that is built upon a peer-to-peer (P2P) network. Monetary transactions are secured by a proof-of-work concept originating in cryptography. Due to this basis, all transaction need to be known to all participants. Therefore, the bitcoin transaction data set is a rich, complete, and consistent data set of a particularly interesting social network, namely one of economic transactions. In this contribution, I want to discuss recent results obtained in a comprehensive study on the structure and the time evolution of the transaction graph.
