Most of us already known the benefits of the implement of the block chain in the financial system. Nevertheless , could you, at least, touch upon 3 more industries or systems that could be benefited for the use of blockchain?
passport control
imagine every airport had a miner, every embassy, every passport agency.(distributing the database to ensure individual employee's couldnt create fakes)
and separately all the departments involved with validating passport applications and doing checks had a multisig address. as the application passes through the departments. it is signed (if accepted) and eventually transmitted to all the miners.
now that passport ID is locked into the chain. showing its been signed and validated and no single person could have faked a passport.
now all the airport terminals can view the passport data using 'block explorer' web-browser tools.
this would save:
IT maintenance as even the cleaner could replace a miner if it packed up, without worry of data security.
auditing can be less costly as the blockchain does most of the checks
human security of data centers wont be required
data centers wont be required
less office staff, less internal investigation/fraud teams
etc etc
