If the data was already uploaded to a blockchain but requires a cipher to decode the encrypted data and also the exact location within the blockchain, all that would be needed is for Assange to send a few emails, or perhaps even a blockchain transaction of some kind.
It would be like the art (images, videos, documents etc) already being stored/saved behind one door somewhere in the world, but you need the key and the exact address to be able to access that art.
Assange provides the key and the address, the artist collects the art and puts it on display.
It has long been suggested that Assange has copies of the original blackmail material used to keep world leaders in check. With the invention of Deepfake it can be argued that any videos that do emerge are just deepfakes.
However if Assange managed to get hold of them and uploaded them to a blockchain somewhere in an encrypted form, that upload will also have date and time stamps within the blockchain that can't be faked and that could prove that they were uploaded before the invention of Deepfake, meaning they are real videos and are a real problem for some very important people.
Not saying it's real or not, but it certainly is possible.\
Edit: OP had another post linking to here showing how images can be stored in a blockchain. Just saw that post.
