Blockchain technology can help us to store data on public ledgers and blockchains if are good enough, will be irreversible.

It can be used in many industries with more transparency than private database from governments and companies. We can only access those data if governments or companies publish them for us and give them open, free access.

With Blockchain, except private blockchains, we all can access public available data and if you search, you will see many projects in different industries and areas already apply blockchains.

This article is over two years old, and all of the things it promised never happened.

The reason for this is that blockchain doesn't solve any technical problems outside of cryptocurrencies and NFTs that cannot be solved better without blockchain.

And "centralized blockchain" is essentially an oxymoron, and any institution thinking of using blockchain to solve a problem is necessarily... centralized. Blockchain outside of the context of cryptocurrencies and NFTs is a solution in search of a problem, and they still haven't found one.

Very possible. Bitcoin was both a breakthrough in terms of finance and technology. We all know that the technology used for most cryptocurrencies will be soon our future. If not it already is our new normal. Everything these days is already digital.

It is also about time that the government start to accept development instead of trying to restrain the use of bitcoin. Although some countries are now more open to cryptocurrency than they were before so maybe they are starting to realize the benefits of crypto to their economy.

Cryptocurrency is here to stay. Not only bitcoin itself but its system, mechanism, and how it operates. Those things can be learned from and be used to innovate even better blockchains.

Well big transformation if they are willing to use it. But do you think they will really use or utilize it? Especially inside the government which we knew that there are some anomaly, modus or under the tables deed? Many are against on using blockchain for it for that sole reason. The transparency will be crystal clear and some of thosw politicians arent ready to be caught in the vanguard. Well not saying they are all guilty but lets agree to disagree here that majority do some hidden thing inside the Government.

These two concepts can not even be mentioned in the same sentence. Distributed ledger demands decentralization while governments are all about centralization.

In any case I disagree with the subject here, [decentralized] blockchain technology has no use for governments and can not change them at all. And as I skimmed through the article my opinion didn't change. The article simply doesn't have any justification for any of the random examples it uses (eg. using it for land registry, healthcare, etc.).

You see it is not about explaining possibility of doing something with a tool, it is all about explaining WHY.
Read the Bitcoin whitepaper (again if you have already). In there Satoshi doesn't only explain how this new payment system works. He also explains why Bitcoin should even exist, and most importantly what problems it solves.

Take land registration using blockchain technology (which so far has only meant injecting an arbitrary data into bitcoin blockchain through OP_RETURN and still use the same centralized database to verify these), what problem does that solve? Why isn't the current centralized system not working? What is its flaws and how does using the most inefficient form of database aka a blockchain solving those issues?
These are the questions they never answer. They just use some pretty words and some buzzwords about a new technology trying to solve everything with it without knowing why or how.

The article being old is proof that this is all empty words by people who neither understand the technology nor understand the problem they claim to be solving.

I keep hearing all those "blockchain has the power to transform" this and that for the last 7 or 8 years. So far, blockchain technology didn't disrupt or change or transform any industry outside the cryptocurrency markets.
It's theoretically possible to implement blockchain technology in the election process to make elections more transparent and honest, but I don't think that the politicians around the world are willing to make such changes.
Perhaps the blockchain technology really has the potential to transform the governments, but are the governments willing to transform themselves?
One blockchain hater said that blockchain technology is a "glorified database". Is this true? Are we applying some "magic powers" to blockchain technology? I don't think that this technology is some kind of magic pill, that will miraculously solve all problems.

There is actually a government developed blockchain  that has worked flawlessly for a decade and more as it's older then Bitcoin!

So you can't say that nothing happened when it happened before the article!  

Blockchain technology would help economies with its features that allow secure and transparent data sharing among multiple parties without a central authority.

Its positive impact would include, the increase in trust and collaboration between government, citizens, and business owners by providing immutable and verifiable records of processes and transactions. It'll, of course, register and lead to Economic growth by supporting new business ventures like decentralized finance, smart contracts, and so on. It'll also reduce bureaucracy, corruption, fraud, etc by enabling digital identity management in land registries, voting, taxation, and healthcare records.

Although there are lots of positive impacts, there would also be negative impacts. They are; conflicts with existing laws, rules, and regulations which would require new ones in order to address the 8ssues of data privacy, taxation, and so on. The second would be technical and operational complexity which may lead to slow operations and delayed results. Also, it'll lead to the redundancy of government in their responsibilities.

Honestly, everything that has an advantage also comes with its disadvantages, and these disadvantages have their respective controllable measure and solutions. So, it'll be worth it, to have Blockchain technology in government and Economic activities.

Blockchain is a decentralized ledger, and it's been known for many years that it can be potentially used for various things that go well beyond cryptocurrencies. There have been some explorations of blockchain voting systems, blockchain ticketing, and the famous IBM corporation has a webpage on Blockchain use cases for governance. So, is it possible to use blockchain for various purposes? Absolutely. But will it become the future? It's still hard to say. There's, first, a matter of trust, which can be difficult for new technologies to gain. Then there's a question of practicality, and whether Blockchain is indeed optimal for certain use cases.
