AQR-O: Quorum-Aware Overlay Optimization Without Quorum-Set Mutation

Trust-plane invariance, timely-quorum covers, and fault-domain-constrained peer selection

Research reportMF-PRISM-DLT-2026-06 / v0.2

Optimize how quorum messages reach a validator while keeping the formal trust predicate fixed. The study uses timely-quorum coverage, diversity constraints and bounded transport changes in a synthetic dissemination emulator.

01
The question

What is this paper trying to establish?

Can message delivery be optimized without mutating the validator’s formal trust configuration?

02
The contribution

The central idea.

Optimize how quorum messages reach a validator while keeping the formal trust predicate fixed. The study uses timely-quorum coverage, diversity constraints and bounded transport changes in a synthetic dissemination emulator.

Current status

Fixed-trust overlay methods and a deterministic dissemination emulator. No compiled hot-overlay Gravity patch, complete SCP simulation, or production performance claim is included.

This report develops a conditional method and evaluates it within the stated evidence. It does not establish production performance, operational safety, or calibrated real-world predictive skill beyond that evidence.

03
Why it matters

What changes if the method holds?

Separating the transport plane from the trust plane creates room to improve timeliness while avoiding silent quorum-set changes that would alter safety assumptions.

04
Independent review

Where scrutiny should concentrate.

The paper identifies the following points as the highest-value targets for independent review.

  1. 01
    Fixed trust versus transport availability and eclipse exposure.
  2. 02
    Arrival-time abstraction and hierarchical quorum formula.
  3. 03
    Synthetic routing, churn and unimplemented production hot updates.
