This is a request to add a periodic adjustment automatically to the fixed payment for validators proposed in DAP phase 2.
The rationale is straightforward; DAP phase 2 moves validation costs to fixed payments to a great degree (in a DOT stablecoin TBD) so the logic is to adjust the fixed validation costs accordingly and automatically along with the current meatspace inflation.
A Shadowstats average for the past 5 years should suffice (average window of the blue line). CPI-U is not as desirable as data center costs have exceeded CPI-U (the official USD inflation rate). The worst case scenario is to keep it fixed forever at the initial rate as this doesn’t consider any inflation/debasement of the USD currency whatsoever.
The current answers have been to either request a continuous OpenGov increase or to include it into the parameters which are not set in stone yet.
The best approach should be to include this fixed payment increase automatically in DAP phase 2 and only launch an OpenGov referendum in case this increase rate needs changing.
Looking forward to hear other possible increase rates based on actual data for data center costs (not sure where to get this data from).
