Homework on High Availability - Questions

  1. It is important for blockchain networks to be high availability networks because the strength of the network itself is that truthfulness can instantly be checked among the network through consensus. Therefore the network needs to be highly available so information can be drawn from it quickly on demand.
  2. Blockchain networks have such high availability because they are decentralized and are not dependent on any centralized point of potential weakness. Therefore the network can be agile and adapt to changing network conditions in the event that some of the network goes on, new nodes can come online for example.

  1. For a network such as financial services, it is imperative that it is available to be accessed 24/7, otherwise rendering it redundant. For blockchain to achieve network reliability it must have a high volume of availability.
  2. Network security is heightened by the volume of users, incentives encourage people to be engaged in the community thus maintaining a high availability.

The higher the availability the more we are incentivized to keep the network, which in turn, makes the network more secure.

The high availability is a result of the network is never turned off, but it is available 24/7/365.

  1. In oder for any global system to be successful it has to be available as frequently as possible to people living in different time zones.

  2. Strong mining incentives coupled with its decentralized nature allows blockchain to have people in the community guaranteeing high availability at all times.

1 Why is it important for blockchain networks to be high availability networks?
High availability enables global usage around the clock.

2 What is it that enables blockchain networks to have such high availability?
Miners create high availability through process called mining. Mining happens because it’s profitable to the miners.

  1. Why is it important for blockchain networks to be high availability networks?
    Because we live in a world where instant availability is in demand. No one wants to wait for anything anymore when we’re so used to have all the information in seconds.
  2. What is it that enables blockchain networks to have such high availability?
    Mining and incentives in it.
  1. When that is the case then everybody around the world can use the blockchain when they see fit. If it wouldn’t be available 24/7 then you have to take notice of the different time zones in world.

  2. Because it is run on a network of nodes. These nodes are spread over the world and keep the network up and running. when one node or several nodes stop working, other nodes will jump in.

  1. It has to be always online to be safe/secured and to also be useful.
  2. That due to incentives there is constant mining.

  1. Why is it important for blockchain networks to be high availability networks?
    As Ivan says. Everyone wants to make money. And you need 24/7/365 availability from all around the world

  2. What is it that enables blockchain networks to have such high availability?
    To keep the network alive nodes, in other words computers will help to secure. If a computer dies seconds later there will be others to help keeping the network alive.
    The reason? Well it is mining and the idea of getting rewards. That all guarantees a high availability of the network

Because block chain is a global network, all you need to is wifi or data and a secure infrastructure and it 24/7

2 Incentive, everyone needs money or a reward.

  1. Blockchain Networks can offer such high HA due to their design. They offer no-single-point-of failure; no-single-point-of-control; Network of Nodes that are available across the globe.

  1. It is important for blockchain networks to have high availability so that it can be used globally at any time with ease. High availability also increases the security within the system.

  2. Incentive mining enables the blockchain network to have high availability. If miners stop, more will come as it becomes easier to miner. This creates a reoccuring onslaught of miners/verifiers

  1. Why is it important for blockchain networks to be high availability networks?
    Transactions/additions cannot be made or verified if the network is unavailable; financial systems will grind to a halt impacting many. A strong network enables security as there are more miners to verify transactions.

  2. What is it that enables blockchain networks to have such high availability?
    Multiple nodes create the high-availability network. Nodes are incentivised to keep the network available (miners make money through mining). If part of a network is lost, new miners can join (in search of a profit)

  1. Because the financial system demands this. You cant shut down the network for a part of the day because it is a global network and people all over the world want to use it at every time of the day.

  2. because they can be used 27/7/365 a day, because miners are basicaly being payd for creating the availability
