Regarding relocation of function references. The fact that the Functions CHIP moved away from having function references be integers (0-999) to instead allowing arbitrary byte strings (0 to 7 bytes in size) makes relocation much less likely to be needed. The VM only allows for one thousand functions, but the set of valid function identifiers is massive. This allows for name spacing. So a ZK verifier library (brought in via read-only inputs) could have all its functions prefixed with âzkâ (reflected in its internal self references) and that way avoid conflict with function names in contracts using it.
