Homework on High Availability - Questions

By that time its expected bitcoin will be valuable enough for the fees to compensate the block reward to miners. This will happen approximately in the year 2140.
Maybe there will be a hardfork to increase the supply beyond 21 million, no one knows for sure :slight_smile:

  1. The blockchain network is based on maths and protocols. Verifications have to be guaranteed 24/7/365 - without that high availability people would again need trust to close time gaps.
  2. Incentives - they determine how the network is protected and how the miners can earn money.

  • Why is it important for blockchain networks to be high availability networks?
    High availability allows the network to work successfully globally. Being useful 24/7, 365, allows all users flexibility and scope to make transactions any where in the world.

  • What is it that enables blockchain networks to have such high availability?
    The network of computers/ nodes that very transactions run 24/7, 365 days per year. Should one node stop working, for example, the network is unaffected and transactions can proceed as normal.

  1. It’s important for everyone involved. Developers, investors, traders and users have 24/7 access to a blockchain network. It’s revolutionary in comparison to the stock and other traditional markets which are open during certain times only. However in a traditional proof-of-work algorithm as the usage grows so do the fees, that’s why many blockchains have come up with sharding mechanisms and different consensus algorithms to tackle the scalability bottleneck. For example, ETH 2.0 (soft launch) is coming out tomorrow, introducing sharding and proof-of-stake algorithm.
  2. It’s incentivized so that every node confirming and keeping track of transactions is rewarded with mining rewards.

  1. This ensures that the blockchain networks are running all the time 24/7 365 days a year.

  2. It’s the incentives to the miners that ensure that there will always be miners to keep the network up and running. If many miners drop out, it means the incentives will become higher to attract new miners to come in

  1. Running 24/7/365 is important from a security point of view. If you want a trust less system and so everyone only needs to trust to maths and protocols then network must run without interruptions. Bitcoin is a perfect example of high availability app. which was never down since inception. Other aspect is also accessibility, comparing to traditional markets, Crypto markets or Crypto economy is available all the time. IE, good luck If you want to send some money to your cousin in SE Asia on Ester Monday (her BD) using bank Wire. If you are lucky, your cousin will get her BD present with 2 weeks delay. With bitcoin, it will be there in minutes without the need of a middleman. Now someone can still say that Bitcoin is not challenging Banks? :slight_smile:

  2. Financial incentives or miners rewards take care for that issue. IE Bitcoin has integrated difficulty adjustment algorithm. So the higher is the total hash rate, the more difficult is to win the bitcoin lottery. This difficulty level adjusts approx. every two weeks. And is a perfect answer to - what happens if a part of network nodes gets down. So when some miners become unprofitable and switch off their machines, difficulty will be lowered and new miners will join. This concept maintains the network permanently in a good shape.

A copy of the network is decentralised and on all miners so if North america went down then it would continue on the network elsewhere

  1. Because everyone needs to check in on it or transaction on it at different times 24/7

  2. Due to its decentralization there is a high number of people on different parts of the world motivated to maintaining it due to the incentives they receive.

  1. Blockchain is to be used for highly important transactions and data, and must be available at all time to efficiently transfer this important data.
  2. Everyone is incentivized to keep the network going through mining and staking benefits.

  1. By being highly available - accessible 24/7 - it becomes efficient, reliable and useful. It can then funcion in realtime and always be in touch with what is happening in every single moment.
  2. The availability is enabled by incentives. As mentioned in the video, what we all have in common is that we want to make money (or get an incentive of some sorts). By varying levels of difficulty levels of mining, the network is self-regulated.

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

High availability is a great selling point for applications or use cases in the future, the infrastructure is already in place, its available anytime, has proven reliability with high security

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

Incentives, everyone wants to make money, so mining makes this possible and the more miners the more secure the system.

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

So that anyone in the world (with internet access) can have access to the network anytime, be united and make money (because this is important for everyone).

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

They are accessible worldwide 24/7/365 (given you have internet access) and they are incentivised, meaning that when a part of the network dies, others will start accessing it through mining.

  1. Because it is used 24/7 worldwide

  2. It is Incentivized by paying miners incentives to protect it.

Are these answers ok? Im new like a newborn baby at all this, this language is very foreign, but ill get it soon enough!!

When blockchain networks hold a high availability then the network is secure with a high level of security and is always accessible, 24/7/365.25

Blockchain net works are incentivised with payments to maintain high availability. These incentives are provided through the process of digital mining.
