It's a memetic disease akin to religion how many person-years of time have been wasted trying to find a use for blockchain lock-in.

Fast blockchains with sub-second block times actually fit. I agree that most implementations of blockchain are awful - but this just technically makes use of the nature of its immutability - and would showcase Ricardian contracts (600+ pages of text) versus smart contracts (garbled memos)

I'd say for that specific example (confirming President's official speeches), regular public/private key systems signed by official key published by the White House would work even better.

As GP said, you are trying to answer a question: "How do I apply blockchain here". This is never a right question, you should instead be asking: "which technology will allow to solve this problem in the most optimal way according to users".

Is everyone (third parties filming a politician or celeb on their own device) going to sign their videos and pay gas fees just in case someone else deepfakes it?

No.

Someone concerned about this is likely to do first-party filming and sign that instead.

Of course it’s still word against word unless the camera itself implements the signing protocol.

.. and in this case, you would not need blockchain, just timestamping server (for example RFC 3161 compliant one)

Probably want multiple servers from multiple countries, to ensure both redundancy and trust. After all, the requests are cheap and small enough.

No. Obama can just release the transcript on the official white house website instead of storing it on multiple blockchains.

The official white house website is vulnerable to being DNS hijacked or shelled.

And blockchains are vulnerable to 51% attacks, especially small ones. In fact, someone can hack the blockchain "writer" that the white houses uses and push a fake transcript.

If the white house security can be hacked, what makes you think the hackers can't just hack the wallets/tools that the white house uses to push the transcript to blockchains?

Even if whitehouse website got hacked, people would quickly fix it.

No so with blockchain - one compromised staffer's computer and blockchain has bad information in it, forever.

That's right. Blockchains are actually hugely impractical.
