- What does it mean when we say that in blockchain, consensus determine the truth?
Consensus is having multiple and different sources to independently confirm the blockchain. Once determined and verified to be the truth, no ‘trust’ is needed or relied upon as ‘consensus’ provides the truth in ‘decentralised’ blockchain.
- How is this different from how truth is determined in a central database?
In a central database, truth is hear-say or an option of one or more, based on their review the database. This process is not necessarily without issues leading to the ‘truth’ being suspect due to intentional changes or ‘honest’ mistakes that render this ‘centralised’ data base imperfect by nature of its composition and construction.
