Replication Data for: The Bitcoin Brain Drain: Examining the Use and Abuse of Bitcoin Brain Wallets
<|begin_of_text|><|start_header_id|>system<|end_header_id|> You are a research archivist expert in dataset metadata. Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'In the cryptocurrency Bitcoin, users can deterministically derive the private keys used for transmitting money from a password. Such “brain wallets” are appealing because they free users from storing their private keys on untrusted computers. Unfortunately, they also enable attackers to conduct unlimited offline password guessing. In this paper, we report on the first large-scale measurement of the use of brain wallets in Bitcoin. Using a wide range of word lists, we evaluated around 3.9 trillion passwords and passphrases. Surprisingly, after excluding activities by researchers, we identified just 1,730 brain wallets worth around $261K in use from July 2011 to February 2017. We find that all but 21 wallets were drained, usually within 24 hours but often within minutes. We find that around a dozen “drainers” are competing to liquidate br' .
