Definition of Proof-of-Stake
It is the alternative to proof of work. Proof-of-stake is a concept that letting know about the capacity of a person can hold the block transactions by checking how many numbers of digitized coins or currency they have. Therefore, a person with more coins can have a greater number of block transactions in a chain.
Brief Explanation of Proof-of-Stake
For the execution of holding the block transaction, the minor or the person has a computing knowledge to deal with different cryptographic calculations to unlock the computational challenges. To hold the transactions in a chain the minor must be aware of all the challenges in a market.
