We don't think so because these smart contract are not using in our daily life. Its very hard ti understand for every person specially un-educated person to use Etherium,polkadot eyc contract address for transaction.
These contracts cannot bear the burden of such a big Government transactions per second.
Agreed. The current system needs to be simplified. Sending to obtuse strings of letters is hard for the average person to understand or use. It will get there. There are several cryptos already that can solve the TPS issue.
Did you mean to say could Crypto replace voting or did you mean to say it could replace the government? Either way the answer to both right now is no. I think fist off voting is a "popularity contest" and using the blockchain for voting wouldn't change that. After all a democracy counts it's votes from most vs least ( minus the United States and our stupid Electoral College). Also I'm not sure how this would change privacy wise? If a blockchain were used to count votes, it would need to be open ledger such as how bitcoins works vs a blockchain say like Monero. I like the theories you've come up with here but sadly I think that is simply all they are.
Good question. Purely replacing government would be difficult, but it could replace aspects of it. IRS would not need to exist. Much of the bureaucrats that maintain billing and support would not need to exist. "Nice to haves" would get voted on. But you will need people to defend the country and build the weapons. Providing for the common defense of a country is supposed to be the main purpose of government.
Popularity is still an element, but it is drastically diminished. You don't need a central figurehead - blockchain could be used to direct major decisions. Department leaders could be individually replaced if they are not doing their job. Their spending would be visible on the public blockchain, allowing citizens to directly reward commitments achieved and punish unfulfilled promises. It could happen faster than the current election system.
Privacy is tricky. Realize the flaw in what I was saying earlier. Perhaps government would be exposed by being on a public blockchain, whereas citizens could use a private blockchain. Effectively the reverse of what we have now. ...or a semi-private blockchain where only the identity of the user and total balance of the account are known - if a politician suddenly gets a $1B donation, questions get asked.
The problem with that, is if there is a private blockchain (like cash), how do you prevent bribery of individual leaders? Maybe it doesn't matter - government employees get replaced faster if they are not doing their job. It's impossible to prevent in any system. Something to think about.
