How the CBRC Use Case Score is calculated

01

6 evaluation categories

Every use case is assessed across 6 categories, each represented by targeted questions about blockchain fit.

1. 01

   Data Integrity & Immutability

   Need for a single, tamper-evident source of truth, strong data protection, decentralised storage, and verifiable transactions.

2. 02

   Performance & Scalability

   Need for efficient, high-throughput, scalable, real-time multi-party access.

3. 03

   Process Automation & Efficiency

   Value from automating processes with smart contracts and eliminating data silos via a unified ledger.

4. 04

   Governance & Information Sharing

   Importance of cross-organisational information sharing, internal and external, and integration with existing systems.

5. 05

   Compliance & Auditability

   Importance of immutable records that are readily available for auditing, especially by regulators.

6. 06

   Adoption & Ecosystem Fit

   Likelihood that users, partners and customers will adopt the solution without significant barriers.

These 6 categories are assessed through 14 specific questions about the use case.

03

Expertise-based weighting, per question

For each of the 14 questions, the 6 persona scores are combined using an expertise-based weighting matrix. The result for each question is a weighted average, not a simple mean.

• 0.3 – 2.0The weight scale, from minimal relevance to maximum expertise. Weights reflect how relevant each domain is to that specific question.
• No zeroesAll 6 personas always contribute. No perspective is ever switched off, whatever the question.
• Capped at 2.0No single evaluator can dominate a question, however central it is to their domain.

On auditability, the Regulatory Compliance Expert carries the highest weight, 2.0, because audit and regulatory compliance are their core domain. On user adoption, the Industry Expert carries 1.8, reflecting deep market adoption experience. On decentralised storage and scalability, the Technical Architecture Expert carries the highest weights.

A worked example: auditability

“How important is it for the records to be immutable and readily available for auditing by external parties, especially regulatory authorities?”

Questions

How is this different from a simple average?

A simple average would treat all six personas equally on every question. The CBRC methodology adjusts influence by expertise, so the most relevant domain experts have more say on each question; prevents domain mismatch, so technical architecture does not dominate compliance questions or the reverse; and preserves diverse input, because all six perspectives still contribute. The result is a more defensible measure of blockchain fit than an unweighted average.

Is the methodology public?

The high-level methodology is public — this page. We disclose the evaluation categories and their intent, the questions and how they map to categories, the evaluator personas and their domains, and the weighting principles with illustrative examples. For procurement, audit or regulatory purposes, we can share a detailed methodology pack, including the full weight matrix and category weightings, under NDA.

How is the score stored and verified?

Once approved, the CBRC Use Case Score and its metadata are certified as a timestamp transaction onchain. That provides an immutable record of the score and the assessment date, a verifiable reference any party can check for themselves, and protection against the score being modified after the fact.

Can I use the CBRC Score in RFPs, audits or regulatory filings?

Yes. It is designed to be used as an objective, third-party assessment of blockchain fit in RFPs and procurement; as supporting evidence in internal audits or risk assessments; and as part of regulatory or compliance documentation where an independent evaluation of technology fit is helpful.
