This new version of the ZoKrates toolbox comes with the following main features. For a full list of the changes, check out the changelog!

Constant declarations

ZoKrates now offers the possibility to declare constants at the module level:

const u32 ANSWER = 21 * 2

No more copy pasting or wrapping in a function!

Constant range checks

When using comparison operators such as a < b, ZoKrates used to have limitations on the size of a and b. These still apply when both a and b are variables which cannot be known at compile time. However, in the cases where the compiler can determine a constant value for one of the bounds, it now accept any value for the other.

Poseidon hashing

ZoKrates now supports the poseidon hash function. Special thanks to @JiangXb-son who submitted a first implementation of this algorithm.
