well imagine many DNA research labs broadcast DNA data to a blockchain so all labs can see the same data. and then use AI to pattern recognise certain features/attributes of that data..
dont think about blockchain as just a currency tool. its a data distribution tool. best used for international data sharing and ensuring everyone has the same exact data
You can ensure that everyone has the same data with a simple checksum. That's how torrents operate - a decentralized sharing protocol of the same static thing. Blockchain is an append-only database, if you don't need tracking the state of some thing, you don't need blockchain, you need decentralized filesharing.
