RE: Steemit Crypto Academy Contest / S5W2 - Get to know the Steem Blockchain
Hey friend,
The POW or Proof of Work is a consensus protocol where equipment or mines are required to be able to create the blocks and record the information, in the process a large amount of energy is consumed (a point that has always been criticized of this protocol) and the The one who manages to solve the mathematical problems that "mining" implies will be the one who receives the reward for having created the block.
You are right friend, The proof of work consensus mechanism is known for its slow processing speed and power consumption which make it very expensive to run or use, also as it's name implies witness are selected from most fastest Blockchain witness after it has been carefully shuffled . In this mechanism you will work extra hard get notified.
Thank you very much for sharing, please you can check my own entry here
Everything has its nuances, there are those who prefer the proof of work for the higher level of security, but it has its considerable energy cost.
