❌ In FHE, it is not possible to break a loop based on an encrypted condition. For example, this would not work:
If your code logic requires looping on an encrypted boolean condition, we highly suggest to try to replace it by a finite loop with an appropriate constant maximum number of steps and use TFHE.select inside the loop.
✅ For example, the previous code could maybe be replaced by the following snippet:
In this snippet, we perform 10 iterations, adding 4 to x in each iteration as long as the iteration count is less than maxValue. If the iteration count exceeds maxValue, we add 0 instead for the remaining iterations because we can't break the loop.
