GPU mining is the use of Graphics Processing Units (GPUs) to "mine" proof-of-work cryptocurrencies, such as Bitcoin. [1] Miners receive rewards for performing computationally intensive work, such as calculating hashes, that amend and verify transactions on an open and decentralized ledger.
Since the creation of bitcoin in 2009, the number of new cryptocurrencies has expanded rapidly. [1]The UK's Financial Conduct Authority estimated there were over 20,000 different cryptocurrencies by the start of 2023, although many of these were no longer traded and would never grow to a significant size.
The exact definition of "stake" varies from implementation to implementation. For instance, some cryptocurrencies use the concept of "coin age", the product of the number of tokens with the amount of time that a single user has held them, rather than merely the number of tokens, to define a validator's stake.

The proof-of-work distributed computing schemes, including Bitcoin, frequently use cryptographic hashes as a proof-of-work algorithm. Hashrate is a measure of the total computational power of all participating nodes expressed in units of hash calculations per second.
Ethereum is a decentralized blockchain with smart contract functionality. Ether (abbreviation: ETH [a]) is the native cryptocurrency of the platform. Among cryptocurrencies, ether is second only to bitcoin in market capitalization. [2] [3] It is open-source software. Ethereum was conceived in 2013 by programmer Vitalik Buterin. [4]

According to SAFTU, South Africa harbors up to 100,000 artisanal miners, known locally as “zama zamas” with most of the minerals derived from artisanal mining “sold to the black market, and ...
In the context of cryptocurrency mining, a mining pool is the pooling of resources by miners, who share their processing power over a network, to split the reward equally, according to the amount of work they contributed to the probability of finding a block. A "share" is awarded to members of the mining pool who present a valid partial proof ...
