1. Why is it important for blockchain networks to be high availability networks?
Blockchain is an open ledger technology, accessible to anyone with a computer or smartphone (as well as an internet connection) worldwide - due to differences in time zones, and the need for users to transact with each other irregardless of their location, the network has to be accessible and operational at all times.
Setting up cryptocurrency mining operations and staking pools (as well as performing financial transactions) requires network participants to invest their hard-earned income into the network, so being able to access and move their funds at any moment is crucial for giving them confidence that the technology is reliable and safe to use.
2. What is it that enables blockchain networks to have such high availability?
As long as there are computers running nodes on the network, the protocols that communicate data between them run 24/7, 365 days a year. These nodes are spread around the world, depending on where the users are located - this decentralised infrastructure protects the network from service disruption otherwise caused by localised outages.
Bitcoin and other similar blockchain networks take advantage of the almost universal human desire to make money, to incentivise users to mine transactions with their computers, for which they are rewarded in cryptocurrency. If a portion of the miners ceases activity on the network (lowering the mining difficulty), other miners will take their place, as there is a greater opportunity for financial returns due to their being less competition for mineable blocks on the network.
Blockchain’s streamlined solutions to all-year-round availability are a significant selling point for the technology, making it very attractive for businesses that want to operate on a global scale, with minimal friction caused by crossing borders and restrictive financial regulations.
