10 years ago, blockchain was just the technology behind Bitcoin, a currency used by the Drug lords in illegal markets on the Dark Web.
Today, the blockchain is seen as one of the technological wonders of our time. The way blockchain technology has been seen by society has been growing along the years. From the slums of the dark web to the hypothetical implementation of CBDCs, blockchain technology has been highly regarded as a technology that can be used by the government to help them with financial policies and a lot more.
In a few years, we will probably see the entry of CBDCs as state digital currencies supported by the blockchain technology, but this will not be something good. Rather than that, they will use it as a tool for control and monetary policy, so I do not think that what they want to do with it will benefit society. Much to the contrary, they already know what the potential of this technology actually is, and they will use it for something nefarious.
How do you see governments making use of the blockchain technology in a few years?
First of all, Bitcoin, like any National currency can be used immorally by people... that doesn't make the cryotocurrency bad. It's people abusing/misusing it, like they would abuse/misuse any good thing for evil. And it's important to note that Bitcoin underlining technology makes exposing bad users easy compared to fiats/national currencies which are quite opaque and are heavily used by drug lords and for other immoral purposes. You could call them dark currencies without being wrong due to their lack of Transparency which is part of the fundamental feature of True Blockchain.
In regards to whether governments will use Blockchain as tool for control... that really depends on whether they weaken or completely discard the features that makes Blockchain harder to use a tool for control. By the way, it can nolonger be a True Blockchain if the features are weaken or discarded... it will become a false Blockchain. So, you will have to make sure bad people in governments do not tamper with Blockchains Features/Ideals/Standards like its Transparency, Decentralization, Fair rule-based protocol, Participatory governance/consensus, Censorship-resistance, Immutability, Permissionlessness/Trustlessness, , Immutability, Pow, etc.
Bitcoin or The Bitcoin System is analogous to a decentralized and interconnected Android Operating system, while alternative Blockchains are like modified Android operating system. All of them most likely won't be in existence if Bitcoin wasn't invented. They owe Bitcoin a lot of respect and should be built to be better/safer Blockchains rather than lowering their standards.
