//! ProgPoW (Programmatic Proof-of-Work) is the Ethereum network's proposed new Application-Specific Integrated
//! Circuit (ASIC) resistant Proof-of-Work mining algorithm.
//!
//! ProgPoW's aim is to reduce the efficiencies of specialized mining devices known as ASIC chips
//! (and accelerated GPU-based setups), and to maximize the performance of General Purpose Hardware (GPUs) to enable
//! more users to compete for new cryptocurrency awarded by the protocol.
//!
//! ASIC chips are those that are tailored to efficiently mining cryptocurrency based on a specific hashing algorithm.
//!
//! GPU mining setups are less specialised are struggle to compete for mining rewards.
//!
//! It would be a change from Ethereum's current PoW mining algorithm known as Ethash.
//!
//! ProgPoW audits have been proposed to analyse the efficiency of a ProgPoW ASICs over
//! GPUs and analysis of the economic impact on the Ethereum protocol.
