Examining the Behaviour of Hyperledger Fabric when World State is Tampered

Overview

When we say “immutability” in blockchain, our general perception is that everything in the blockchain system is immutable, that is, no one can modify it. In fact, in a blockchain network, each node is maintaining both the state and the transaction logs. When things are running normally, the consensus mechanism ensures the state maintained in every node is identical, which makes blockchain a robust and trustworthy environment for business use.
