The blockchain provides an immutable public record. Yes, not necessary but still an interesting approach and actually a decent fit for a blockchain. A blockchain might still be an over fit but it's useful if I claim to have an undoctored video at a certain point in time but don't want to release it, immediately, and need a distributed way to validate that claim.

Like I said in my above comment, it doesn't solve all of the problems but at least we can begin establishing a record of source.
- krastanov 8y agoI am pretty sure that what you are calling a block chain is actually just a single hash or at most a Merkle tree. You do not need a consensus algorithm (PoW or PoS or whatever), i.e. you do not need a block chain if all you want is decentralized verification of a current or future publication.
- kakarot 8y agoI was just making an arbitrary suggestion based on previous work by proofofexistence.com. I didn't suggest it was the only way or the best way forward. I realize that people all the time try to say "Blockchain would be great for ____" so you're probably a little hypersensitive and I get that, but the suggestion of a blockchain was arbitrary and tangential to the real point of my post, so I don't really feel like getting into it right now.
