This proposal is intended to re-think the staking limits that are currently set on Kusama, and alter them such that, whilst keeping _some_ degree of _chaos_ in the backpocket, the chain remains safe over the long term. First, let’s look at the current staking limits of Kusama.

Note that the minimum nominator bond is in PLANKs, meaning that it is actually **0.1KSM**. 

Recall that the NPoS election process, in order to be both successful and safe, contains 4 main steps. 

1. Snapshot creation.
2. Signed submissions from staking-miner.
3. Unsigned submissions from validators, as backup. 
4. Solution verification.

Our experimentation has unraveled that, as it stands now, the bottleneck for the Kusama network (and Polkadot and Westend) is the **third** step, and the largest input data for which this step could be executed, in WASM, without running out of resources (weight, memory, block-length), is when there are at most around **12500** nominators in the system. Note that this number is expectedly lower than Polkadot’s 22500, because Kusama opted to allow for up to **24** nominations per nominator. Thus, we need to assume the worst case in our experimentation, namely that each nominator is indeed using all of their 24 nominations.

To reflect this, we need to alter a runtime type parameter, which can only be done as a part of runtime upgrade, not as a standalone council motion. This is done in the following pull request: 
* [https://github.com/paritytech/polkadot/pull/5000](https://github.com/paritytech/polkadot/pull/5000)

Lastly, since Kusama network is already fully using the bags-list pallet, it can freely open its door to many more _nomination intentions_, being sure that the top 12,500 are selected by the bags-list. To reflect this, we suggest **removing the maximum nominator count limit** entirely, and **keeping the 0.1KSM** as the minimum bond for nominators.

**NOTE**: We might be able to tweak these number to slightly higher values again, once these two pull requests are merged into production: 

* [https://github.com/paritytech/substrate/pull/10340](https://github.com/paritytech/substrate/pull/10340)
* [https://github.com/paritytech/substrate/pull/10821](https://github.com/paritytech/substrate/pull/10821)

Similar to [the corresponding proposal for Polkadot](https://polkadot.polkassembly.io/post/905) with exactly the same argumentation, we also strongly advise the Kusama network to use a reasonable value for minimum validator bond. For that, we suggest an initial value of **1 KSM** as a relatively low starting point, which similarly can be further increased if the need arises. 

All in all, we propose the following call to be enacted on Kusama **after** [PR#5000](https://github.com/paritytech/polkadot/pull/5000) is _merged_ and _enacted_.

**NOTE**: minCommission might be altered in [Ref #176](https://kusama.polkassembly.io/referendum/176) to 3% and if executed, should be reflected as well. 


: 

1. For Kusama, have a minimum nominator bond of 0.1KSM and remove the maximum nominated count limit. 
2. For Kusama, suggest an initial value of 1KSM for minimum validator bond.
3. Execute the above call after PR #5000 is merged and enacted, adjust minCommission value if Ref #176 is executed.
