One potential use for blockchain (or chain of hashes) might be for authorizing video by putting each of the frames in a blockchain. That way the raw video can be authorized to not have been tampered with.
- CerebralCerb 7y agoYou could just hash the video file.
- kiallmacinnes 7y agoYes, and in the process 1) not spend CPU cycles extracting frames... 2) not have a permanent+widely distributed copy of `$illegal` thing someone tried to upload. 3) have a technology that works regardless of content type! amazing! It supports new video codecs right out of the box ;)
- PeterisP 7y agoThat doesn't seem to follow, what would prevent someone from doing exactly what you describe after creating a tampered video?
