Homework on High Availability - Questions

  1. Since blockchain is a database that people around the world using, it is important that the database/blockchain stays available 24/7. For example if database stores medical information about your health, you want that info accessible 24/7 in case of emergency.
  2. The bitcoin blockchain network secured by process called mining, computers that secure the network through process of using electricity to create new blocks. People who run those equipments have incentives to do do it by a subsidy called block reward. So if part of the network goes down and the mining process becomes easier, the incentive drives other people to start mining because it becomes more profitable, which increases the security.

  1. It is important for blockchain networks to be high availability networks because it increases the security.
  2. High availability on blockchain networks is available through mining. Miners earn money. When more miners are active it becomes harder to mine. When less are active it becomes easier. Everyone is incentivized.

  1. It’s important for blockchain networks to be high availability networks because these networks will be accessed all the time (24/7/365). Unlike the stock market, there will be no opening and closing of trading. These are global networks which are in demand at any time, for any multitude of reasons.
  2. Such high availability is accomplished through incentives. Every sector of the industry is incentivized (remunerated) to keep the network going (eg. Miners).

  1. Why is it important for blockchain networks to be high availability networks?

Because we can have confidence that it will never be offline. It means the network is 365 days 7/24 hours of availability.

  1. What is it that enables blockchain networks to have such high availability?

A lot of computers compound the network, so even if one part of the network is down the rest will continue running and all the time more computers are being connected to the network.

Yes, but full nodes alone is not enough. It’s mainly the miners who wants to earn money by including transactions into a block. As long as the bitcoin network is producing blocks, the network keeps being alive.
