How much validator downtime is tolerated before emissions are impacted?
Grace windows and the penalty curve are enforced by THEO AI health scoring on-chain, not by manual review, ensuring consistent and auditable application across all validators.
Short, infrequent downtime is tolerated through documented grace windows that prevent transient network issues from affecting emissions. Sustained downtime degrades THEO AI health scores and reduces emission share proportionally. Severe outages exceeding the policy threshold can trigger slot suspension.
Understand the broader Autheo platform
This answer covers one part of the Autheo ecosystem. To understand how this capability fits into the full platform, start with the core Autheo overview and architecture pages.
Grace Windows
The protocol distinguishes between transient and sustained downtime. Transient unavailability (defined in protocol policy and typically measured in minutes per epoch) is absorbed by grace windows without penalty, recognizing that brief network issues happen to even the most reliable operators. This avoids penalizing operators for issues outside their control.
Sustained Downtime Penalty Curve
Beyond grace windows, THEO AI health scoring applies a graduated penalty curve. Health scores drop with the severity and duration of downtime, and emission share scales with health score. The curve is smooth (not a step function) so small issues produce small penalties and large issues produce large penalties, never a binary cliff.
Slot Suspension
Severe outages, particularly those that combine with double-signing or other adversarial behavior, trigger slot suspension. Suspended slots earn no emissions and require remediation before reactivation. Operators can avoid this entirely by using managed hosting partners InfStones or Zeeve, both of which target 99.9%+ uptime.
Key Statistics
Expert Perspective
“Grace windows are the most operator-friendly feature a network can add. Brief outages from software updates, power events, or connectivity hiccups should not cost you a month of emissions.
