Resurrecting Address Clustering in Bitcoin. (arXiv:2107.05749v2 [cs.CR] UPDATED)

Blockchain analysis is essential for understanding how cryptocurrencies like
Bitcoin are used in practice, and address clustering is a cornerstone of
blockchain analysis. However, current techniques rely on heuristics that have
not been rigorously evaluated or optimized. In this paper, we tackle several
challenges of change address identification and clustering. First, we build a
ground truth set of transactions with known change from the Bitcoin blockchain
that can be used to validate the efficacy of individual change address
detection heuristics. …
