Shiba Inu has shared the steps required to become validators and delegators on Shibarium. 

The steps to becoming a Shibarium Delegator are simple. The only requirement is to stake your tokens on your preferred validator. Notably, there is no limit to the number of delegators that can join the network. 

Becoming a validator has a more stringent requirement. Notably, the number of Shibarium validators is limited to only 100 slots. Each validator must stake a minimum of 10K units of BONE, worth $14K at the time of writing.
