In blockchain technology, nonce means a number added to a hashed, or encrypted block, that, when rehashed, meets the difficulty level restrictions. Blockchain miners aim to solve the nonce.

Blocks are data structures within a database where cryptocurrency transaction data are permanently recorded; once written, it cannot be altered or removed.

Bitcoin mining is how new bitcoins enter into circulation. It's also a critical component of the security of the blockchain ledger.

A hash is a function that converts an input of letters and numbers into an encrypted output of a fixed length.

Proof of work is the process of validating transactions on a blockchain to confirm transactions, close a block, and open a new one.

Cryptocurrency difficulty is a measure of how difficult it is to mine a block in a blockchain for a particular cryptocurrency.

A target hash sets the difficulty for cryptocurrency mining using a proof-of-work (PoW) blockchain system.

Proof of Capacity is a consensus mechanism that uses a mining node’s hard drive space to decide the mining rights on the blockchain network.

Litecoin is a fork of Bitcoin that uses a different protocol. Learn how to mine LTC and decide whether it is profitable based on the costs and competition.

A block header is the unique identity of a particular block on a blockchain and is hashed by miners for rewards.
