How secure is a blockchain-based system?

A blockchain-based system is as secure and robust as its underlying consensus method. The most well-known consensus method is proof of work which is used by bitcoin. However, during the past years, a multitude of consensus methods are designed and developed to be used for different applications.

How does the blockchain make decisions?

All the decisions are taken by the leader or a board of decision makers. This isn’t possible in a blockchain because a blockchain has no “leader”. For the blockchain to make decisions, they need to come to a consensus using “consensus mechanisms”.
