[alto] Draft: Alto for the blockchain

[Shenshen Chen <[e-mail]>]

Dear authors,

In draft-hommes-alto-blockchain-02 section 5, it mainly talks about
bitcoin. Would you be glad to add another section about health care?

The healthcare has a great interest in the blockchain. A doctor needs
patient’s record from different hospitals. A patient cares about the
security of his medical record. The blockchain could be the solution
since it keeps secure data in a distributed, encrypted ledger and
control who has access to that ledger. It treats a doctor’s visit as a
transaction. Then people validate the transactions—in health care,
likely a physician or pharmacist trusted with an access key.

More use cases make the draft more general, especially about “be aware
of different roles for bitcoin”.  Rules in healthcare are patient,
doctor and hospitals. Those roles may be treated as wallet, miner and
relay nodes. By showing other use cases of blockchain still use those
standard roles, it’s more convincing to claim that Alto should be
aware of those 3 different roles.

Hope this helps.

Best Regards,
Shenshen
