Bitcoin Magazine The Scroll: A Brief History of Wallet Clustering Our previous post in this series introduced the basic idea behind wallet or address clustering, the trivial case of address reuse, and the merging of clusters based on the common input ownership heuristic (CIOH), also known as the multi-input heuristic. Today, we’ll expand on more sophisticated clustering methods, briefly summarizing several notable papers. The content here mostly overlaps with a live stream on this topic, which is a companion to this series. Note that the list of works cited is by no means exhaustive. Early Observational Studies – 2011-2013 As far as I’m aware, the earliest published academic study that deals with clustering is Fergal Reid and Martin Harrigan’s An Analysis of Anonymity in the Bitcoin System (PDF). This work, which studies the anonymity properties of bitcoin more broadly, in its discussion of the on-chain transaction graph, introduced the notion of a “User Network” to model the relatedness of a single user’s coins based on CIOH. Using this model, the authors critically examined WikiLeak’s claim that it “accepts anonymous Bitcoin donations.” Another study that was not published as a paper was Bitcoin – An Analysis (YouTube) by Kay Hamacher and Stefan Katzenbeisser, presented at 28c3. They studied money flows using transaction graph data and made some remarkably prescient observations about bitcoin. In Quantitative Analysis of the Full Bitcoin Transaction Graph (PDF), Dorit Ron and Adi Shamir analyzed a snapshot of the entire transaction graph. Among other things, they note a curious pattern, which may be an early attempt at subverting CIOH: We discovered that almost all these large transactions were the descendants of a single large transaction involving 90,000 bitcoins [presumably b9a0961c07ea9a28…] which took place on November 8th, 2010, and that the subgraph of these transactions contains many strange looking chains and fork-merge structures, in which a large balance is either transferred within a few hours through hundreds of temporary intermediate accounts, or split into many small amounts which are sent to different accounts only in order to be recombined shortly afterward into essentially the same amount in a new account. Another early confounding of this pattern was due to MtGox, which allowed users to upload their private keys. Many users’ keys were used as inputs to batch sweeping transactions constructed by MtGox to service this unusual pattern of deposits. The naive application of CIOH to those transactions resulted in cluster collapse, specifically the cluster previously known as MtGoxAndOthers on walletexplorer.com (now known as CoinJoinMess). Ron and Shamir seem to note this, too: However, there is a huge variance in [these] statistics, and in fact one entity is associated with 156,722 different addresses. By analyzing some of these addresses and following their transactions, it is e in a formal or creative style for better SEO.Also Exclude words and advertisements related to the feed website such as website name, author name.
