The term "proof of work" was first coined and formalized in a 1999 paper by Markus Jakobsson and Ari Juels. [2] [3] The concept was adapted to 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). [4]

The most widely used proof-of-work schemes are based on SHA-256 and scrypt. [19] Some other hashing algorithms that are used for proof-of-work include CryptoNote, Blake, SHA-3, and X11. Another method is called the proof-of-stake scheme. Proof-of-stake is a method of securing a cryptocurrency network and achieving distributed consensus through ...
It intends to allow ADA token holders to create proposals that may be voted upon by the community and, if successful, implemented. [35] As with other proof-of-stake cryptocurrencies, Cardano offers "staking", which allows token holders to set-aside (delegate) tokens to potentially "validate" transactions on the same blockchain (Figure 1). The ...
Hashcash is a cryptographic hash-based proof-of-work algorithm that requires a selectable amount of work to compute, but the proof can be verified efficiently. For email uses, a textual encoding of a hashcash stamp is added to the header of an email to prove the sender has expended a modest amount of CPU time calculating the stamp prior to ...

For a blockchain transaction to be recognized, it must be appended to the blockchain. In the proof of stake blockchain, the appending entities are named minters or validators (in the proof of work blockchains this task is carried out by the miners); [2] in most protocols, the validators receive a reward for doing so.
