    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.

      Polestar uses contracts and audits to ethically source materials, not blockchain. It uses blockchain as a shitty append-only SQL database to (apparently) tell you where the materials came from. Let me quote from Circulor’s website:

      data can be fed seamlessly to the blockchain via system integration using RESTful Web Service APIs with security and authentication protocols

      So the chain is private and accessible only through a centralized, authenticated REST API. This is a traditional web application. A centralized append-only ledger is not even a blockchain.
