OK, who are the experts on #distributedsystems on the #fediverse? There is a new #fep for implementing a scalar #logicalclock in #activtypub, #fep4f18.
I'm especially interested in mitigations for Byzantine faults in the system; right now, it's kind of hand-wavy based on value and trust […]

After some discussion, I added a #fep for a scalar #logicalclock for the #activitypub network.
I'm excited to try this out; I think it can have some interesting uses.

Add: FEP-4F18: ActivityPub Network Time
[Logical clocks](https://en.wikipedia.org/wiki/Logical_clock) capture the causal ordering of events in a distributed system. This proposal introduces a logical clock system for the ActivityPub network.

7/ Deterministic testing — Centralized RNG, injectable DbRand, plus LogicalClock / SystemClock give fully repeatable, seedable tests. The filesystem is the last remaining item to make injectable.
