How to start staking Algo? What’s the inflation rate?

In Algorand we do not have POW style mining nodes. You can participate in consensus by having an account on a node that has stake and the account is put online. That said, currently any account that has tokens earns rewards at the same rate (online/offline). The Algorand Foundation site covers a bit of this in these two links:

We are going to be releasing some more information how rewards are calculated very shortly. Hope this helps.

Can everyone " Configure Node as a Relay" to earn the relay rewards?
