Exercise 06

Objectives: staking mechanics, validators rotating

Content: This is rather a reading exercise. Familiarize yourself with the staking mechanism in Substrate (pallet staking). Then, check out our current adaptation (pallet elections).

Once you get some understanting, launch your local chain. Expand the validator set by submitting changeValidators extrinsic as sudo and observe an actual rotation of authorities. Then, use a non-validating account to nominate one of the validators. Verify your actions in the 'Staking' tab of PolkadotUI.
