To gradually increase the number of slots for validators, I propose scheduling the increase over time for 200 slots. The scheduled event mechanism (submitted by external motion to council and then pass to referenda queue for vote) aims to increase the number of validator slots steadily upon certain conditions. In the case of Polkadot:

- An increase by 1 every era (24hs)
- A repetition of the increase for 100 eras for now.

This mechanism can be canceled or completed after 100 eras, and at that moment the community will be able review network metrics. The proposal aims to avoid an abrupt increase in the number of validators on the network and follows the recommendation of the parachains team as noted [**here**](https://polkadot.polkassembly.io/post/263). 

- The proposal suggests gradually increasing the number of validator slots over time.
- The increase would happen by adding 1 slot every 24 hours.
- This increase would be repeated for 100 days.
- The proposal can be canceled or completed after 100 days.
- The goal is to avoid a sudden increase in the number of validators on the network.
