Compared to proof-of-work, proof-of-stake uses only a fraction of the electricity. See proof-of-stake algorithm. In addition, proof-of-work (PoW) miners can become monopolistic, and any single ...

When using a proof-of-work method, new coins are said to be "mined." However, in a proof-of-stake algorithm, new coins are "minted." In practice, the mining term is used in both cases. Delegated ...

The concept was adapted from digital tokens by Hal Finney in 2004 through the idea of "reusable proof of work" using the 160-bit secure hash algorithm 1 (SHA-1). Following its introduction in 2009 ...
