Key features of blockchain technology

When a medical document is generated and signed, it could be written into the blockchain, which provides patients with the proof and confidence that the record cannot be modified. These personal well being data could be encoded and stored on the blockchain with a private key in order that they’re solely accessible to specific individuals, thereby guaranteeing privateness.
