What do I answer if someone asks me this question? I have done some research but I am still confused so kindly help me out. And this is my first thread on forum kindly excuse me if I made any mistake.
Thank you!
Blockchain is a system that records transactions that have occurred then stored by all computers spread on the network itself, for example if you pay for coffee with Bitcoin, then you transfer to the address of Bitcoin cafe that sells the coffee in peer to peer and this transaction will recorded on all computers scattered on the Bitcoin network, so it will be harder to hack hundreds or even thousands of computers in the transaction, in terms of security Cryptocurrency really needs this Blockchain system.
