I started learning cryptography for blockchain and got carried away with a lot of stuff. It was quite confusing what to learn. But you made it crystal clear. Thank you!

Sir, my question is, if Blockchain uses Hash Function which is very secure then why we hear about the bitcoin hacking news...??

@ogmentry8849 3 жыл бұрын

I guess that's majorly because someone/some party is able to gain access to 51% of the nodes of the blockchain network. I don't think anything else is possible/feasible to hack or gain access of any blockchain like bitcoin

Thank you @@ogmentry8849 . I think by saying 51% you mean that it's 'chain' must be small then only any hacker can hack it easily and cover it's 51%...?

Yes, small blockchains are more vulnerable and easier to attack as compared to the large ones

@@hellosumitg You're right. And in blockchain world, small cryptocurrency networks like Pluto, Deflect suffer from this

Sir,@@learnwithwhiteboard is there some other way that a hacker can hack the block..?
