Rewarding the finding of zeroes of a hash function
We have an arbitrary and public hash function $\text{Hash}$. … Could I possibly publish a function $F$ (that is, publish an algorithm that returns $F(M)$ given $M$) such that
$F(M)=K$ whenever $\text{Hash}(M)=0$, where $K$ is a previously defined private key that …
