There is no government, company, or bank in charge of bitcoin. Another early example of a proof of work algorithm was adam back's hashcash. His creation was initially meant to limit email spamming and ddos attacks. Because they are decentralized and without a proof mechanism, the network and the data stored within it would be vulnerable to attack or theft. Fine, but what does that mean?

Fine, but what does that mean? Unlike traditional currencies such as dollars, bitcoins are issued and managed without any central authority whatsoever: Thus each block has a chain. Rather than doing away with proof of work entirely, primecoin seeks to make its proof of work useful. Because they are decentralized and without a proof mechanism, the network and the data stored within it would be vulnerable to attack or theft.

Bitcoin uses the hashcash proof_of_work function as the mining core. His creation was initially meant to limit email spamming and ddos attacks. Each block contains the hash of the preceding block. …bitcoin miners deploy huge amount of resources in the form of mining hardware (capital investment) and electricity (operational however, before the bitcoin are awarded to the successful miner, other miners will need to check and verify that the figures were correctly derived. In order for the bitcoin system to work, people can make their computer process transactions for everybody. How does proof of work, um,work?

They need a lot of efforts to be executed.

As such, the process consumes a colossal amount of electrical power. Who founded proof of work?

Recall that in bitcoin a large variety of we still need to create money and disburse it somehow, but since we are decentralized, we have to be able to do so without any central authority. So, when a node receive a transaction it verify it. Bitcoin uses the hashcash system to generate blocks. What if we eliminated the proof of work step for the miners and what are the consequences of doing so?
