A post on the Reddit community r/bitcoin revealed an encrypted 7zip file possibly linked to Wikileaks founder Julian Assange. The file was found in the output script from a transaction that took place on Jan. 5, 2017, and was mined at block height 446,713. Speculation surrounds the purpose of the file, with some speculating that it could be an encrypted link to the switch or files exposing secrets. The transaction occurred five days before Assange read the Bitcoin blockchain hash from block height 447,506. Assange's Ecuadorian asylum was revoked and he was arrested on April 11, 2019, when police raided the embassy.

The contents of the 7zip file are unknown until someone cracks it, and a Reddit post discussed whether adding arbitrary data to the Bitcoin blockchain through Ordinals was a legitimate practice.
