GitHub Reinstates Tornado Cash in Read-Only Mode

Tornado Cash code was restored by GitHub in “read-only” mode after clarification from the U.S. Treasury’s Office of Foreign Asset Control (OFAC).

After much criticism by the crypto community, the U.S. Office of Foreign Asset Control updated the FAQ section. It states the imposed sanctions do not prohibit U.S. people from reading, discussing, teaching, and sharing Tornado Cash’s code. However, the Office of Foreign Asset Control has not removed an outright ban.

“While engaging in any transaction with Tornado Cash or its blocked property or interests in property is prohibited for U.S. persons, interacting with open-source code itself, in a way that does not involve a prohibited transaction with Tornado Cash, is not prohibited.”
