Everyone probably wondered, there is a blockchain, there are distributed capacities that are scattered around the world, to turn off all this, you need to turn off the Internet, so that there the Internet needs to do all communication, there is also a transmission via satellite and offline wallets - where information is transmitted along the chain Now not one supercomputer is able to resist the volume and power of calculations operated on in the blockchain ...
and what do we all consider all these capacities? BTC BTC BTC
Pardon me for not understanding you, but what do you mean when you say
capacities?
from the history it was first scientific experiments there dna calculations or trajectories of movement of various objects in space, but who rules? who gives the job? What is the result and where are all the results? is there any goal?
Experiments are obviously done to know more about our life in general. Calculations and trajectories, movement of heavenly bodies and other objects in space are measured because they may pose as a threat to our own planet (say, a collision) and again, to better understand things. Who gives the job? Our endless pursuit for knowledge and to quench the thirst of our curious minds. Results? Technology. Goal? Understand things and help us live better and easier.
I would like to raise this question in front of the community.
No solid questions were raised, honestly.
all miners compete for 12.5bts
but who gives the tasks and what is calculated in these hashes?
The protocol gives the tasks, obviously, and the miners themselves chose to compute these super complex algorithms in exchange for the block reward + transaction fees. The people then give value to bitcoin by trading it, and so that block reward is what the miners are aiming for as incentive for their work.
