Exploring Unconfirmed Transactions for Effective Bitcoin Address Clustering. (arXiv:2303.01012v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
The development of clustering heuristics has demonstrated that Bitcoin is not
completely anonymous. Currently, existing clustering heuristics only consider
confirmed transactions recorded in the Bitcoin blockchain. However, unconfirmed
transactions in the mempool have yet to be utilized to improve the performance
of the clustering heuristics.
In this paper, we bridge this gap by combining unconfirmed and confirmed
transactions for clustering Bitcoin addresses effectively. First, we present a
data collection system for capturing unconfirmed transactions. Two case studies
are performed to …
