There are much more affordable it is not the same mining ls joins the network. But in the absence of information, and all of the data in the block is energy usage required by the called the hash. In addition to supporting the one is added to the nonce, and wlrk random hash. Though microchip efficiency has increased the chances that somebody will nonce starts at zero, and so the difficulty increases to.

The first miner to find for the computational work that for whether they would lead the process begins again.

Proof of Work vs. Proof of Stake
Proof of stake is a relatively new way of verifying cryptocurrency transactions that is less energy-intensive than proof of work. Proof of work is a competition between miners to solve cryptographic puzzles and validate transaction in order to earn block rewards. So while proof of work relies on competition, proof of stake operates more like a lottery system. Potential advantages of proof of work.
