How Does Hashing Secure the Creation of a New Block in a Proof-of-Work System?
In a PoW system, miners must find a nonce (a random number) that, when combined with the block's data and then hashed, results in a hash value that meets a specific target difficulty. This process is computationally expensive and is the 'work' that provides the cryptographic proof.
Once the proof is found, the block is broadcast and validated by the network, securing its place in the chain.
