This premise of a free\ndecentralized transactional network however requires, in its current\nimplementation, unrestricted access to the ledger for peer-based transaction\nverification. A number of studies have shown that, in this pseudonymous\ncontext, identities can be leaked based on transaction features or off-network\ninformation. In this work, we analyze the information revealed by the pattern\nof transactions in the neighborhood of a given entity transaction. By\ndefinition, these features which pertain to an extended network are not\ndirectly controllable by the entity, but might enable leakage of information\nabout transacting entities. We define a number of new features relevant to\nentity characterization on the Bitcoin Blockchain and study their efficacy in\npractice. We show that even a weak attacker with shallow data mining knowledge\nis able to leverage these features to characterize the entity properties.","url_abs":"http://arxiv.org/abs/1810.11956v1","url_pdf":"http://arxiv.org/pdf/1810.11956v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"characterizing-entities-in-the-bitcoin","repo_url":"https://github.com/Maru92/EntityAddressBitcoin","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
