Evidence
Show what happened — don’t just claim it.
NEXGEN turns actions into records designed to be proven. Sealed at the moment they happen, witnessed by independent nodes, and checkable by anyone — without trusting the system that produced them.
Sealed records
Evidence, not assertions
Citadel produces cryptographically sealed records so you can show what happened rather than simply claim it.

Independent nodes witness and seal each outcome, so no single operator — including us — has to be trusted.
