A little bit ago some asked a question about why the hate of the blockchain, and that got me thinking if there even was a legitimate use case where the blockchain would be beneficial, but I couldn't think of one outside maybe some sort of decentralized bank, but before I knew I was thinking it would instantly turn into some crypto scheme and strapped it, because crypto currencies are a scam on every level -- and no they aren't private or secret as some think either.

So I wanted to ask the community. Instead of using the blockchain for crypto, is there a better use where the blockchain could benefit society?

The "Blockchain" technology is gonna become crucial in the future of AI and Deepfakes.

Since videos, and especially still images can be faked. They would be treated just like witness testimonies, evidence that can be falsified.

What I think will happen is that people would have to use live internet connection to verify a video.

So what happens is that whenever a video is recorded, there will be a "blockchain verify" feature in the camera settings, when enabled either the video feed or the hash of the packets of video data is sent to a blockchain network where it gets timestamped and stored permanently on the blockchain.

The network would consist of various nodes that ideally aren't government run. Think like the ACLU, EFF, or Journalists, or people who independently want to join the network. Each would run their own node independently.

So any time theres suspicion that a video may be faked, the courts can just ask the network to send their own copy of the blockchain, if theres a consensus, then the video can be proven to have been created at the time that is timestamped. So there's no way of creating a fake video evidence after an incident since you wont have the timestamp on the blockchain.

Why would this require a blockchain, as opposed to standard public servers run by the same parties mentioned?

Because the fewer servers the more trust you need in the servers owners. And the trust is not limited by intentions, it's also limited to their ability to not be compromised by private or state sponsored hackers.
