What is cryptocurrency mining and how does it work?

Mining software builds or receives a candidate block containing valid transactions and required metadata. Changing a nonce or other permitted field changes the hash, so the miner can test a new candidate many times.

A result is valid only when it satisfies the network target. Difficulty expresses how demanding that target is and may change according to a published adjustment rule. A hash is quick to verify even when finding one required substantial work.

Nodes validate the proof, block structure and transactions before extending the chain they consider valid. A protocol may define a block reward and fees, but actual income also depends on competition, uptime and costs. Quinvarium has no live reward or difficulty data.
