I'll likely get downvoted but Polestar, the EV automaker that used to build performance variants for Volvo, uses blockchain to track minerals used in their EV's.

Circulor Circulor's blockchain technology enables tracing of extracted raw materials, particularly those with significant impact to communities and the environment.

I like that they use blockchain to ensure the minerals they use aren't coming from negative sources but I'm sure someone will argue and say it's stupid or that SQL can do the same.

@itsmect mentioned this too but it is wild how this community just hates cryptpo. There's a good chance the instance you're on accepts it for donations. Why would they do that if it is so unusable and bad? Open source everything except the money. Makes no sense.

Lol after this comment Bitcoin surpassed silvers market cap making it the 8th most valuable asset in the world. So glad people who don't understand it and hate it don't get to ruin it for the rest of us.

I'm kinda amazed I haven't seen anyone mention the biggest upcoming use case for block chain here. In a world where anyone can create any media with Ai we are going to need robust systems of cryptographic proof of origin and history that anyone can access and that is not controlled by anyone who may wish to manipulate information. The exact strength of block chain.

As for cryptocurrency I'm seeing a lot of confusion here in how people think it works. While scaling has been an issue its not an insolvable one and multiple solutions exist. The issue with crypto is its image not the tech in general. And thats a combination of people using it to scam and governments/banks doing their best to discredit it.

git is a blockchain, just without PoW
