Fault-Domain-Aware Federated Quorum Certification

Adversary policies, domain-cover margins, and exact portfolio certification

Research reportMF-PRISM-DLT-2026-04 / v0.2

Certify quorum safety under correlated failures rather than validator counts alone. Organization, region and infrastructure incidents are modeled explicitly through domain-cover policies and exact witness searches.

01
The question

What is this paper trying to establish?

How should federated quorum safety be certified when failures are correlated by organization, region, or infrastructure?

02
The contribution

The central idea.

Certify quorum safety under correlated failures rather than validator counts alone. Organization, region and infrastructure incidents are modeled explicitly through domain-cover policies and exact witness searches.

Current status

Fault-domain certification methods and exact analysis of an illustrative topology. The case study is not production Metriq infrastructure evidence.

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?

Counting validators can badly overstate resilience when many share one failure domain. Explicit domain-cover policies expose those correlated risks.

04
Independent review

Where scrutiny should concentrate.

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

  1. 01
    Completeness and truth of the declared failure-domain catalog.
  2. 02
    Domain-cover characterization and structured-fault assumptions.
  3. 03
    Distinguish illustrative topology margins from production resilience.
