Proof of work vs proof of stake
There are two main consensus methods for a blockchain: proof of work (PoW) and proof of stake (PoS). PoW, a consensus method with a high mining cost but which makes.

Proof of work is a consensus algorithm that was first proposed by Adam Back in 1997. The algorithm requires nodes to perform an expensive computation called a proof of work.
Proof of stake is a new consensus algorithm that improves upon proof of work. Unlike proof of work, which requires miners to expend energy to confirm transactions, proof of stake.
