◆ IsSolvable()

bool IsSolvable ( const SigningProvider provider,
const CScript script 
)

Check whether we know how to sign for an output like this, assuming we have all private keys.

While this function does not need private keys, the passed keystore is used to look up public keys and redeemscripts by hash. Solvability is unrelated to whether we consider this output to be ours.
