Tornado Cash, a non-custodial open source software project built on Ethereum, allowed users to mix their coins through the use of the Tornado Cash smart contract, obfuscating the previous trail of the coins (which are of course being transacted across a transparent ledger). <\/p>\n<p>The sanctions placed were particularly notable because they were placed not on an individual person or particular digital wallet address, but rather the use of a smart contract protocol, which in the most basic form is just information. The precedent set by these actions are not ideal for open source software development.<\/p>\n<figure><img decoding=\"async\" src=\"https:\/\/bitcoinmagazine.com\/wp-content\/uploads\/2024\/11\/tornado-cash-stats.png\" title=\"\"><\/figure>\n<figure><img decoding=\"async\" src=\"https:\/\/bitcoinmagazine.com\/wp-content\/uploads\/2024\/11\/tornado-cash-deposits-and-withdrawals-per-week.png\" title=\"\"><\/figure>\n<p>Following the announcement, it could be seen that Circle, the centralized issuer of stablecoin USDC, blacklisted every sanctioned address from using USDC.<\/p>\n<blockquote class=\"twitter-tweet\" data-width=\"550\" data-dnt=\"true\">\n<p lang=\"en\" dir=\"ltr\">NEW: @circlepay&#39;s USDC has officially blacklisted every Ethereum address sanctioned by the US Treasury.<\/p>\n<p>&mdash; Dylan LeClair \ud83d\udfe0 (@DylanLeClair_) <a href=\"https:\/\/twitter.com\/DylanLeClair_\/status\/1556708643617312768?ref_src=twsrc%5Etfw\" target=\"_blank\" rel=\"noopener\">August 8, 2022<\/a><\/p><\/blockquote>\n<p><script async src=\"https:\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script><\/p>\n<blockquote class=\"twitter-tweet\" data-width=\"550\" data-dnt=\"true\">\n<p lang=\"en\" dir=\"ltr\">Cross reference the latest tweets from <a href=\"https:\/\/twitter.com\/usdcblacklist?ref_src=twsrc%5Etfw\" target=\"_blank\" rel=\"noopener\">@usdcblacklist<\/a> with the addresses in the Treasury announcement. <\/p>\n<p>Link to Treasury sanction list: <a href=\"https:\/\/t.co\/7VJ8Wjse0j\">https:\/\/t.co\/7VJ8Wjse0j<\/a><\/p>\n<p>Stablecoins are (obviously) not censorship resistant. <a href=\"https:\/\/t.co\/a22qAXl1S5\">pic.twitter.com\/a22qAXl1S5<\/a><\/p>\n<p>&mdash; Dylan LeClair \ud83d\udfe0 (@DylanLeClair_) <a href=\"https:\/\/twitter.com\/DylanLeClair_\/status\/1556709124666179584?ref_src=twsrc%5Etfw\" target=\"_blank\" rel=\"noopener\">August 8, 2022<\/a><\/p><\/blockquote>\n<p><script async src=\"https:\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script><\/p>\n<p>These actions have led many to question the safety of holding centralized digital assets, even for non-criminals who just prefer to use privacy-enhancing tools.&nbsp;<\/p>\n<p><a href=\"https:\/\/twitter.com\/pseudotheos\/status\/1556734521063706624\" target=\"_blank\" rel=\"noopener\">https:\/\/twitter.com\/pseudotheos\/status\/1556734521063706624<\/a><\/p>\n<p>The total number of USDC addresses that are blacklisted now stands at a current total of 81.

Yet, more importantly in light of many government regulations that are taking shape and are likely to come, Bitcoin\u2019s true decentralized properties and censorship resistance will be just as important.<\/p>\n<figure><img decoding=\"async\" src=\"https:\/\/bitcoinmagazine.com\/wp-content\/uploads\/2025\/01\/bmpro-subscribe-button.png\" title=\"\"><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>The U.S. Treasury sanctioned the Tornado Cash mixing tool, setting a precedent for blocking financial privacy and censoring open-source code.<\/p>\n","protected":false},"author":2736,"featured_media":7656,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[36],"tags":[85,737,742,444,1239],"class_list":{"0":"post-7652","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-legal","8":"tag-bitcoin-magazine-pro","9":"tag-mixers","10":"tag-mixing","11":"tag-sanctions","12":"tag-u-s-treasury"},"author_data":{"id":2736,"name":"Dylan Leclair And Sam Rule","nicename":"dylan-leclair-and-sam-rule","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/2b6b26c44e1d269b6e0f99be25243a520901d88fba7899ea664ee1c543b3ff6d?s=96&d=robohash&r=g"},"featured_image_url":"https:\/\/bitcoinmagazine.com\/wp-content\/uploads\/2024\/11\/law.png","_links":{"self":[{"href":"https:\/\/bitcoinmagazine.com\/wp-json\/wp\/v2\/posts\/7652","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/bitcoinmagazine.com\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/bitcoinmagazine.com\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/bitcoinmagazine.com\/wp-json\/wp\/v2\/users\/2736"}],"replies":[{"embeddable":true,"href":"https:\/\/bitcoinmagazine.com\/wp-json\/wp\/v2\/comments?post=7652"}],"version-history":[{"count":0,"href":"https:\/\/bitcoinmagazine.com\/wp-json\/wp\/v2\/posts\/7652\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/bitcoinmagazine.com\/wp-json\/wp\/v2\/media\/7656"}],"wp:attachment":[{"href":"https:\/\/bitcoinmagazine.com\/wp-json\/wp\/v2\/media?parent=7652"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/bitcoinmagazine.com\/wp-json\/wp\/v2\/categories?post=7652"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/bitcoinmagazine.com\/wp-json\/wp\/v2\/tags?post=7652"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
