Can the Nonce Be Used to Reverse-Engineer the Block’s Data?
No, the nonce cannot be used to reverse-engineer the block's data. The hash function is a one-way function, meaning that while you can easily verify the output (the block hash) given the input (the block data including the nonce), you cannot derive the input from the output.
The nonce is merely one piece of the input that satisfied the difficulty target.
Glossar
Block Data
Content ⎊ Block Data encompasses the structured collection of validated information aggregated by a miner or validator before being permanently appended to the blockchain ledger.
The Nonce
Variable ⎊ The Nonce is a variable data field included in the header of a Proof-of-Work (PoW) block, serving as the sole element miners are permitted to adjust during the computationally intensive mining process.
Nonce
Function ⎊ A nonce, short for "number only used once," is a crucial component of the block header in Proof-of-Work blockchains.
