What is the task of miners in a blockchain network?

Miners determine the consensus rules that should be followed and interfere when these rules are broken.

Miners act as a single third party to aggregate records and provide trust in the network by the miners' authority.

Miners are computers that allow access to the blockchain, ensuring the number of corrupt nodes will stay low.

Miners are nodes that compete for a reward by calculating the correct nonce to make a transaction possible.
