The cost of being a validator is around $100-$200/month. The expected time commitment is around 5-10 hours/month.
Kubernetes is best for cluster management. It's possible to do makeshift cluster management on your own, although Kubernetes is now a standard for cluster orchestration among DevOps engineers. We recommend using Kubernetes infrastructure.
At Sifchain we believe that the Archival is most complete, but feel free to make a different choice based on personal preferences.
The calculation for this is as follows:
Validator & Delegation Rewards = [30M Rowan / (total_rowan_staked_and_delegated - total_rowan_staked_by_sifchain] + Block Rewards (Variable).
Some rewards earned by Validators are subject to lock-up periods. We're currently designing this and will provide more information later.
Yes, Validators are held accountable for their proper participation in our network and are therefore eligible to be slashed for misbehavior. For slashable conditions, please refer to additional information here.
Our un-bonding period is currently set to 21 days. More information can be found here.
This is currently in discussion by our team. We will provide additional information around this once we have it.
