General Cryptocurrency Terms

blockchain
Blockchains are distributed ledgers, secured by cryptography. They are essentially public databases that everyone can access and read, but the data can only be updated by the data owners. Instead of the data residing on a single centralized server, the data is copied across thousands and thousands of computers worldwide. More detailed information available at: https://en.wikipedia.org/wiki/Blockchain

Node A computer that possesses a copy of the blockchain and is working to maintain it.

Mining
The process of trying to ‘solve’ the next block. It requires obscene amounts of computer processing power to do effectively, but is rewarded with ether.

Mining rig
A computer especially designed for processing proof-of-work blockchains, like Ethereum. They often consist of multiple high-end graphic processors (GPUs) to maximize their processing power.

Fork
A situation where a blockchain splits into two separate chains. Forks generally happen in the crypto-world when new ‘governance rules’ are built into the blockchain’s code. Some more information available at: https://en.wikipedia.org/wiki/Blockchain#Hard_forks

Hard Fork
A Hard Fork is a radical change to the protocol that makes previously invalid blocks/transactions valid (or vice-versa), and as such requires all nodes or users to upgrade to the latest version of the protocol software.

Soft Fork
A Soft Fork is a change to the software protocol where only previously valid blocks/transactions are made invalid. Since old nodes will recognize the new blocks as valid, a softfork is backward-compatible. This kind of fork requires only a majority of the miners upgrading to enforce the new rules, as opposed to a hard fork which requires all nodes to upgrade and agree on the new version.

PoW
Proof-of-work. The current consensus algorithm used by Ethereum.
