Important Points on  Bitcoin Network
Bitcoin is a system for generating addresses where bitcoins can be received and stored.

Bticoin has a method for ensuring that only the rightful owner of bitcoins stored in an address can move them to a new address.

Bitcoin is a database of all past transactions which is used to prevent double spending of the bitcoins stored in an address. 
This database is calledthe blockchain

Mining is essentially a computationally hard search problem.

Hyperledger is called blockchain because each block is cryptographically linked with previous block
And use pbft for consensus ( Leader selection - round robin,2/3 nodes need to agree)
Finality is immediate compared to Bitcoin and Ethereum.
