Target number of pools, Pledge influence
Abstract
Raises the target number of stake pools (k) from 500 to 600 and the pledge influence (a0) from 0.3 to 0.35. Test action submitted from DRepTalk on preprod to exercise the parameter change flow. Please do not treat it as a real proposal.
Changes:
- Target number of pools (k): 500 to 600. The constitution allows 250 to 2,000.
- Pledge influence (a0): 0.3 to 0.35. The constitution allows 0.1 to 1.
Motivation & rationale
A higher k lowers the saturation point, so stake spreads across more pools and large operators have less room to grow a single pool. On its own that would weaken the incentive to pledge, so a0 rises slightly at the same time to keep pledge meaningful for pools close to saturation.
With k at 600 the saturation point drops by about one sixth. Pools above the new point earn less until their delegators move, which is the intended effect. The higher a0 lowers every pool's maximum rewards a little through the factor 1/(1+a0) and gives part of it back to pools with high pledge. Both values stay well inside the constitution's limits (k 250 to 2,000, a0 0.1 to 1.0). This action exists to test the DRepTalk submission flow on preprod, the numbers are illustrative.
