blockchain is important because the business runs on information , the faster it recieves and the more accurate it is, the better.
the data within blocks are encrypted by complex algorithms.
Every users in the bitcoin network has two keys public key and private key.
public key is the address that everyone in the network knows of but private key is unique address that only the user has knowledge of like password.
the number of bitcoins is send through a wallet address through hashing algorithm all of these will be part of transaction details.these details are encrypted using encryption algorithms and using fills unique private key this is done to digitally sign the transaction and to indicate the transaction came.
