Because the nonce is only 32 bits and the hash is , there are roughly four billion possible nonce-hash combinations that must be mined before the right one is found. The process of verifying transactions and adding them to the blockchain is done through a consensus mechanism, a set of rules that govern how nodes on the network come to an agreement about the state of the blockchain and the validity of transactions.
