This statement does not align with the latest simulation results I shared and on which this description is based. You have to reset all coins of the selected stakers to age 1. Otherwise the most powerful stakers will always be eligibile to solve a data request.
Regardless of that, I'm not even sure what decrementing the amount of coins would look like? That sounds permanent and at some point you won't be able to solve data requests anymore regardless of the coin age?

This introduces a pretty straightforward mechanism for unifying mining and witnessing eligibility through a single Proof-of-Stake consensus algorithm.
Because this mechanism requires a non-trivial bootstrapping period, a second WIP shall be drafted, describing such process and the details of the transition into 2.0.
The () things in front of every article in the specification are left empty on purpose while we shuffle things around, and will be changed later to include incremental article numbers we can refer to.
