Why is it important for blockchain networks to be high availability networks?
It is important that they be high availability networks because they have the potential to carry a large number of important financial and supply chain transactions across the entire globe 24x7x365.
What is it that enables blockchain networks to have such high availability?
What enables blockchain networks to have such a high availability is a super high level of redundancy. Multiple network nodes means that there is no one single point and failure and the system continues to function even if there are a large number of individual node failures.
