Ethereum Classic is a blockchain-based distributed computing platform that offers smart contract (scripting) functionality. [1] It is open source and supports a modified version of Nakamoto consensus via transaction-based state transitions executed on a public Ethereum Virtual Machine (EVM).
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.
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.
Each block includes the cryptographic hash of the prior block in the blockchain, linking the two. The linked blocks form a chain. [3] This iterative process confirms the integrity of the previous block, all the way back to the initial block, which is known as the genesis block (Block 0).
Whereas permanent forks (in the sense of protocol changes) have been used to add new features to a blockchain, they can also be used to reverse the effects of hacking such as the case with Ethereum and Ethereum Classic, or avert catastrophic bugs on a blockchain as was the case with the bitcoin fork on 6 August 2010.
Avalanche is a decentralized, open-source Layer-1 blockchain that uniquely combines a tri-chain architecture (C-Chain, P-Chain, and X-Chain) with customizable Layer-1 networks (formerly known as “Subnets”), enabling diverse applications and sovereign blockchains within its ecosystem. [1]
Each block contains a SHA-256 hash of the previous block, [70] chaining them in chronological order. [ 7 ] : ch. 7 [ 70 ] The blockchain is maintained by a peer-to-peer network. [ 25 ] : 215–219 Individual blocks, public addresses, and transactions within blocks are public information, and can be examined using a blockchain explorer.
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 ...
