I like webghost0101's Idea:

[...] a blockchain linked video camera where metadata of footage gets written into the chain to combat fake news and misinformation.

The goal would be to create a proof and record of original footage, to which media publishers and people who share can link towards to verify authenticity/author.

If the media later gets manipulated or reframed you would be able to verify this by comparing it to the original record.

blockchain is a totally useless extra bit glued on there. All the real evidence will be the cryptographic signatures added by the hardware manufacturer (which can be faked, but requires extracting the keys from the "security chip" in the camera which may be very difficult)

all the blockchain does at that point is provide a timestamp of "signed hash of the picture+metadata was uploaded on x date" which can easily be done without blockchain too

This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.

Be warned:

If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.
