Roke Puzzle Day Puzzle

The puzzle

Roke brings the physical and digital together to make the world a better place: we’re a catalyst!

Here's a Roke-themed cryptarithm (left). Each letter represents a different digit (0 to 9), except for I and S which share the same value. Can you find which number each letter stands for, to make the sum add up? There are two possible solutions. 

The answer is below, so don't scroll down too far just yet!

Need a hint?

If you're struggling to solve the problem with pen and paper, then it might help to know that I and S both have the value 3.
