Why doesn't Bitcoin migrate to proof-of-stake?
After reading a little bit about different consensus algorithms, I am just trying to understand why Bitcoin still uses proof-of-work. This consensus algorithm being exponentially expensive, and resource intensive, doesn't it make more sense for…

How does proof-of-stake "mining" work?
I know and understand the concept of proof-of-stake. Instead of requiring users to do a certain amount of power-intensive hashing "work", it requires you to own a certain stake of the currency in order for you to mine new coins.
But how does the…

In Proof-of-Stake, can the same miner mine a block multiple times in a row?
In Proof-of-Work, there are no rules on who will mine the next block - the selection is random and proportional to miners' computing power.
How is the next miner selected in various Proof-of-Stake block creation algorithms? Can the same miner /…
