  2. GPU mining - Wikipedia

    en.wikipedia.org/wiki/GPU_mining

    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.

  3. Proof of stake - Wikipedia

    en.wikipedia.org/wiki/Proof_of_stake

    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. [3]

  4. Cryptocurrency - Wikipedia

    en.wikipedia.org/wiki/Cryptocurrency

    Like crypto, their data is stored on the blockchain. NFTs are bought and traded using cryptocurrency. The Ethereum blockchain was the first place where NFTs were implemented, but now many other blockchains have created their own versions of NFTs.

  5. Proof of work - Wikipedia

    en.wikipedia.org/wiki/Proof_of_work

    At the IACR conference Crypto 2022 researchers presented a paper describing Ofelimos, a blockchain protocol with a consensus mechanism based on "proof of useful work" (PoUW). Rather than miners consuming energy in solving complex, but essentially useless, puzzles to validate transactions, Ofelimos achieves consensus while simultaneously ...

  6. Ethereum - Wikipedia

    Ethereum enthusiasts gather for a Merge party in San Francisco in 2022. Ethereum 2.0 (Eth2) was a set of three or more upgrades, also known as "phases", meant to transition the network's consensus mechanism to proof-of-stake, and to scale the network's transaction throughput with execution sharding and an improved EVM architecture.

  7. Mining pool - Wikipedia

    en.wikipedia.org/wiki/Mining_pool

    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 ...

    ETH is the second most valuable token in terms of market share; switched to PoS (the “merge”) on September 15, 2022; progenitor of Ethereum Classic [1] [6] Arbitrum? Offchain Labs ETH: Optimistic rollup Yes EVM-compatible Layer-2 on Ethereum [7] Base: June 15, 2023 Coinbase: ETH: Optimistic rollup Yes EVM-compatible Layer-2 on Ethereum [8 ...

  9. Cloud mining - Wikipedia

    en.wikipedia.org/wiki/Cloud_mining

    Cloud mining is the process of cryptocurrency mining utilizing a remote data center with shared processing power. [1] Cloud mining has been used by ransomware groups and scammers to launder cryptocurrency. [2] This type of cloud mining enables users to mine bitcoins or alternative cryptocurrencies without managing the hardware.
