  • Why is it important for blockchain networks to be high availability networks?
    Because any blockchain works 24h/7 and truth need to verified and accessed all the time. It complete difference comparing to banks for example that bank transactions only works from monday to friday and then have holidays during the weekend :slight_smile: bitcoin transactions can be send any day any time.

  • What is it that enables blockchain networks to have such high availability?
    Making money incentive, if any computer in the networks stops working, then miners can make more money and new computers join the network.

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

  • Because in order to be used globaly, people need infrastucture, available at all time. This can allow many other applications to be build on top of blockchain.

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

  • Incentives. If a portion of the network dies for some reason, immidiately other computers will join the network. Because of mining. Mining is how the network is protected and how the miners earn money for keeping the network alive. Everyone are united when it comes to making money, and this is how the network is able to run 24/7/365.

The block reward gets halved every 4 years and doesn’t adjust based on the demand. Unless you are counting fees the miners also receive. :slight_smile:

    Considering, in the case of Bitcoin without any doubt is because is a mission critical network, is our money there. For the enterprise also have to be, they are trusting their investments and services for 3rd parties using the network, this means money and reputation.
  • What is it that enables blockchain networks to have such high availability?
    The network is not centralized in one entity and all are incentivated

So…the right answer must be?

To be precise, after every 210,000 blocks, The block subsidy is cut in half :stuck_out_tongue_winking_eye:
(roughly every 4 years)

Answer to this question is that people will always be incentiviced to mine bitcoin. Because if you successfully mine a block, you get the current block subsidy + all transaction fee’s of the transactions that are included in that block.

If Suddenly, many people stop mining, the difficulty of mining would become easier, so others will be happy to mine again. So as long as people like to make money, the bitcoin network will keep producing new blocks and confirming your transactions.

Every 2016 blocks, the difficulty gets adjusted to keep an average of 10 minutes per block
(2016 blocks should be mined in 2 weeks)

  1. Why is it important for blockchain networks to be high availability networks?
    it is important for blockchain networks to be high availability networks because there are transactions being made globally all the time. The high availability means that blockchain can run at all times any day of the year, no days off. There are a number of things that enable blockchain networks to have a high availability. Look at answer to #2

  2. What is it that enables blockchain networks to have such high availability?
    Mining enables blockchain networks to have such a high availability. Because a miner is incentivized to keep the network functioning. When there is money to be made, someone will do the job. Even a loss of power to a part of the world means that there will be an increase in mining in another part of the world to pick up for the loss of miners. This incentivizes miners to have an easier time to consensus. Thus, make more money.
