RE: Solving Real World Problems – Improving The Quality of Life The Decentralized Way
I don't understand how a healthcare blockchain is any better than a well designed central database which all hospitals could be forced to use. With regular backups to avoid the wannacry issue.
Also on privacy: will this make health records public? If so, will 3rd parties pick up on this data and start using it for marketing, loan applications, insurance etc etc?
No, centralized databases proved itself untrustful as the concept of being centralized holds the one and only source of trust, and if it gets compromised (and it will, 0day using viruses will appear periodically) there will be data loss/exposure, varying from non-zero to 100% (assuming there are backups made, and level at which data is encrypted).
Blockchain can eliminate this problem, as it gives extreme level of trustfulness to database current state, due to multiple trust nodes over the network which one by one sign trustful transactions.
However, your point is valid, because there are multiple nodes which hold same data state and all transactions being publicly available, the privacy is to be concerned about. There are ways to make nodes do extra steps on assuring transaction stays private and does not expose critical data. But the certainly we can say that, centralized database has definite advantage over blockchain (yet) at this point.
You can read this article as it has points I gave in this commentary: http://www.multichain.com/blog/2016/03/blockchains-vs-centralized-databases/
Thanks for the detailed opinion @tensorflow!
Great post @infovore!
Follow you:)
Couldn't have given a more succinct answer. Thanks for dropping by.
They could do encryptions on names and sensitive data, but still make most info public if there is a need.
Costs for what and how long thing take and where items are sourced from need to be shown. When everyone knows the costs we can better know if we r getting ripped off or not and go somewhere else
Exactly. Most companies contract private blockchains for their decentralization forays
Blockchain is not the future. It is the present and happening! Steemit is one of the best products of blockchain technology!
