Thank you, Ambatman..
The core idea is about keep a negative-hash value we may possibly find during a very normal mining process, that we regularly discard them. Just think if we keep and write them in blocks - once they get found! This is assumed there might be lots of benefits in. Just tried to explain it in more detail in reply above (to stwenhao).
Yeah I made the post before the above so sent it before checking the newer explanation.
Sniped
Thank you mixoftix for further clarification. It's clearer now.
Instead of discarding these hashes, store their nonces or metadata in the block
I can see the benefits in this as you have mentioned.
But Storing negative nonces is practical in a separate Negative Coin blockchain or sidechain,
but including them in Bitcoin's block requires a protocol change, which is unlikely
This is assumed there might be lots of benefits in.
Yeah assuming it meets demand and doesn't end as namecoin.
