Smart Contracts in medical sector.

Smart contracts work by following “if/when >> then…” statements that are written into code on a blockchain. A network of computers, centralized or decentralized, executes the actions when predetermined conditions have been met and verified. These actions could include releasing diagnostic to the appropriate parties, registering a patient, sending notifications, or issuing a medical certificate. The blockchain is then updated when the transaction is completed. That means the transaction cannot be changed, and only parties who have been granted permission can see the results, for example the doctors and the patients.
