32 bits is actually just 4 billion values. Technically it isn't enough to reliably find valid blocks with today's difficulty if that's all that you modify.
That's why current miners tamper with both the coinbase transaction, timestamp AND the nonce to find potentially valid blocks in mining.
- mthoms 10y agoInteresting. Is that allowed by the protocol?
- Natanael_L 10y agoYes, because there's multiple valid ways to format coinbase transactions and there's a few bits worth of margin in the timestamps that you can change.
