NegativeSigmoidSteepness
Error v290 → current 19.4The sigmoid steepness parameter cannot be negative.
Encountered by: subnet owners
Why This Error Exists
Sigmoid steepness affects consensus weight distribution curves. Negative values would invert the curve, which is mathematically invalid for the consensus mechanism.
From Chain Metadata
Only root can set negative sigmoid steepness values
What This Means
The sigmoid steepness parameter cannot be negative.
Common Causes
- Providing a negative value for sigmoid steepness
- Integer overflow resulting in negative interpretation
How to Fix
- Use a positive value for sigmoid steepness
- Check for integer overflow in parameter calculation
