#dusk $DUSK @Dusk
Dusk's rolling-finality mechanism recently changed from counting a fixed number of consecutive attested blocks to a variable count based on how many lower-priority candidates failed to get attested in the same round. I read that twice.
Most people assume "trustless" means a system that never needed to be adjusted — the math either works or it doesn't, permanently.
My first read matched that assumption. If consensus is genuinely trustless, why would the specific mechanism deciding finality need to change after launch at all?
Then I sat with what that change actually reveals. Dusk's own engineering update describes this shift as refining how the network handles messy rounds — rounds where multiple candidates competed without clean resolution. That's not a bug-fix for broken math. It's evidence that the original threshold-design carried assumptions about typical network-conditions, assumptions that needed revisiting once real-world rounds turned out messier than the initial design accounted for.
That distinction matters more than it sounds. A truly assumption-free system wouldn't need version-two logic for handling edge-cases it supposedly already covered.
Where I actually land: consensus mechanisms don't get to "trustless" once and stay there permanently. They get closer to it through iterations that expose which assumptions the original design didn't fully account for — and Dusk's own rolling-finality update is a documented instance of exactly that happening.
