I m more concerned about the 5th one. Because "corruption" is a thing, No machine or human can escape for long. If it cannot be thrown off the table, then,after sometime various blockchain scams will rise. World may face the biggest security threat and could collapse. Under the AI or one/group of persons.
@sayakpramanik55275 жыл бұрын
Rich people, industrialists will try to avoid public blockchain due to lack of privacy. Those people do lots of illegal or unauthorised transactions. So they will not want to open it up in front of everyone. Though the address is anonymous, still media, govt can at least track any big amount of transactions. And in any new technologies, only the big industrialists invest. So is the future of public blockchain in danger? * Please correct me I'm wrong somewhere *

Sir I have a doubt...As we know that the mathematical puzzle will be solved by miners,So for example if a single miner solves the puzzle by accessing the blockchain database then he gets to know more than 50% of knowledge on blockchain data. So he can single handedly hack it instead of waiting for 51% attack. Is that possible??

No bro, its not easy. You can view the articles how much computational power required to just break a bit coin. Its need a lot of electricity which equal to some small countries requirement if he goes for mining

1. Most technologies are complex, especially when it comes to finance... Why even have it on the list? People using block chain (bitcoin for example), do not need to know the underlying theory on how it works to use it. 4. Security and transparency are the main benefits of block chains and the reason of why it was invented... If you want to have privacy, go via a private block chain or make a deal with a bank. 5. Do i even need to comment on this... Same can be said about anything, if a bank has it's staff compromised by more then half of the people, then it's pretty much lost... Right? The like to dislike ration on this video makes me loose faith in humanity.
