The whole point of using a blockchain is to let people in particular, people who don't trust one another share valuable data in a secure, tamperproof way.
Blockchain technology is most simply defined and best suited when decentralized. Assets when decentralized, allows full real-time access and transparency to the public.
Not so sure Musk will consider on-boarding on hive though , I don’t really see him as a decentralization proponent. My opinion though!!
