With proof-of-stake (PoS) systems, in some cases, the probability of securing a block is tethered to the amount of stake a validator has within the system. #blockchain #ProofOfwork #PoW I want to focus on Proof of Work as this is the system which currently secures the most value in the crypto currency space. It’s hard to calculate the real power consumption of a blockchain. Estimates are mostly concerned with the current hash rate (how many tries to solve the puzzle are executed each second) and the efficiency of the used hardware.

Essentially, PoW requires members of a community to solve challenging puzzles. This work builds on previous puzzle solutions. As a result, PoW is a way of verifying current and past transactions. Proof of Work (commonly abbreviated to PoW) is a consensus algorithm used for preventing the 51% attack or double-spends.
