MERITS OF BLOCKCHAIN.

[enogheghase123]

we are know that the blockchain system is ict inclined, you have to be a computer literate to  be able to make use of the blockchain technology, so that will be a demerit to blockchain as we know, not everyone is literate when it come to ict.

I think the merits of blockchain include its immutable, transparent and distributed nature atleat no single point of failure! I am concerned though, the fact that a transaction can't be recovered still makes non blockchain systems a million times better! Blockchains which provide you nothing like a private key will always have transactions stuck.

A well-designed blockchain doesn’t just cut out intermediaries; it reduces costs, increases speed, reach, transparency and traceability for many business processes.For example, the healthcare industry is obligated to safeguard personal information about your health. The Health Insurance Portability and Accountability Act (HIPAA) requires health professionals to protect your personal information, which is no easy task.

1. Wrong. A blockchain is slow, inefficient and expensive to run.

Blockchain’s secure technology offers an ideal way to create a shared network of healthcare data with near-perfect security. It is simply a superior way to store, share and protect sensitive data among everybody involved in keeping you healthy.

2. What a true blockchain offers are mainly censorship resistance and decentralization. A healthcare database doesn't need both of them.

That’s right — blockchain can untangle your mess of electronic health records and, most important of all, give YOU control of your personal medical records and who gets to see it...
ARE THERE DISADVANTAGES IN BLOCKCHAIN? WHAT ARE THEY? PLEASE LET US KNOW..

3. Go back to 1.

I think you are correct and I total agree with you... A true blockchain hovers largely around the breaking of censorship and a full decentralized system. A lot of blockchain in recent time has proven to be slow, expensive, and thereby very inefficient..

A huge improvement of the blockchain is really needed to finally make its merits worth it.

Could you explained to me the between this ERC20, DAG and Blockchain? This are some of the basic of cryptocurrency which one should know. I have some information on block chain but when it comes to DAG I do not have that much information. ERC20 also we know that it is a platform of ethereum network however there are many platforms for cryptocurrency claiming that their platform is good and fast like the NEO platform. However, is not all this I have come to research about the DAG could you simplify this to me? This may be off topic but I bet you have some expertise on this. And I would like to see your post reply so that others will know also.

EG imagine a doctors surgery of 6000 patients has a chain of hashes. the personal data not being the chain. but being a UTXO database of encrypted data. and each new block of daily updated records is updating hashes. not clear text data.

each doctors surgury strand of chain. hass a block or UTXO header that gets added to a master chain. and so the network is not validating what the clear text says. but validating the hashes add up.
and its the doctors and patients in their smaller subchains that validate that personal stuff

ok, but the real question is WHY?!!!
it is not about how it is done it is about whether doing it that way is better than how we are currently doing things.

imagine each doctors clinic/surgery have a little black memorystick that is plugged into a electric wall socket with a usb outlet
that memory stick. is the node. now realise each doctors clinic/surgery has one.

now the health care system can sack all the auditors and data security guys. and just get a janitor replace a memory stick if one develops a fault.

letting doctors be doctors and let more of the treasury funds be used for healthcare instead of administration
walk into any doctors clinic and ull see less non-medical staff shuffling papers.

less surgery/clinic managers fiddling with numbers so they can vacation 48 weeks a year at others expense
...
now with all that said there are many places where blockchains are useless, but when there is a scenario that data needs to be in more than one location and edit/append data to it from more than one location. then there can be some advantages.

the more wider field of multiple locations and multiple entities needing more than just viewing privileges. the more a blockchain can be seen as beneficial.

you dont need to be ICT literate

most cars are run by computers. theres no longer a physical steel shaft from the steering wheel of a car to the wheels. its now moved by separate motors controlled by computers.

yet an ICT illiterate person just sees wheels, doors, carseat and a steering wheel.
its for the ICT literate to make things simple for the illiterate

Hahaha. I take some, only that little some, of your opinions with respect because I know you are a technically inclined person, and someone to learn from. But that's slowly going away.

now the health care system can sack all the auditors and data security guys. and just get a janitor replace a memory stick if one develops a fault.

What a world that would be.

letting doctors be doctors and let more of the treasury funds be used for healthcare instead of administration

They can do that today without a "blockchain". Why don't they?

less surgery/clinic managers fiddling with numbers so they can vacation 48 weeks a year at others expense

The power of "Blockchain Technology". Amazing.

That can be done securely using an SQL database.

Is the "blockchain" not an append-only ledger?

that doesn't exactly answer my question though. it only talks about how the blockchain technology is going to used in this particular case.
my question is basically why would you use it instead of regular methods. you mentioned less paperwork and less staff. ok, lets make it digital with a database and a server. but that doesn't still have to be a blockchain.
