What is a blockchain?

A decentralized, distributed public ledger that uses encryption to store and chain blocks of data chronologically.

What is a node in a blockchain?

A computer that connects to a blockchain network and can read and write data on it.

What's the role of a miner in blockchain?

A user who validates transactions, adds new blocks to the blockchain, and receives cryptocurrency rewards.

What is a block in a blockchain?

A structure containing transaction data for cryptocurrency transactions. Each block in the chain gets a unique 'nonce' and a 'hash' to prevent tampering.
