Envision Blockchain’s Best Practices for Digitizing Methodologies
At Envision Blockchain, we've spent years navigating the complexity of carbon methodologies across registries. Our work maintaining the open-source Guardian platform, and delivering the Managed Guardian Service (MGS), has taught us that digitization isn't just a tech upgrade — it's a mission-critical bridge to scale, cost-efficiency, and global trust.
Through our Methodology Breakdown webinar series, most recently featuring VM0042 v2.1 for Improved Agricultural Land Management, we've identified a clear and repeatable approach for turning dense methodology PDFs into dynamic, traceable, and automated policy workflows.
Here are the best practices every innovator should follow when beginning their digitization journey:
1. Start with Research, Not Code
Don’t touch a keyboard until you’ve absorbed the methodology. That means reading the registry documentation, the methodology PDFs, and any associated templates or calculation tools. Understanding the intent behind each step ensures your digitized workflow aligns with what validators and registries expect.
2. Map the Workflow End-to-End
Before building, visualize. Create a workflow diagram that outlines the actors, actions, and documents from project registration to credit issuance. This map becomes your north star during schema and policy development.
3. Break Down the Quantification Logic
Every methodology includes formulas, parameters, and inputs. Use a structured Excel format to list required inputs, variables, formulas, and expected outputs — this is your schema backbone. For example, in VM42 v2.1, we captured over 160 schemas to support multiple quantification approaches and decision trees.
4. Build Schemas Intelligently
Schemas are the heart of a Guardian policy. They define what users need to submit and how data flows. Leverage conditional logic, visibility settings, and calculation references to reduce user burden and ensure data integrity. In our VM42 implementation, we embedded logic that activates sub-schemas only when specific project activities are selected.
5. Use the Guardian’s Policy Workflow Engine Strategically
Once your schemas are built, assemble them into a policy using Guardian’s visual editor. Include roles (e.g., project proponent, validator, verifier), forms, and approval stages. Use dry-run mode to test every step before going live on mainnet.
6. Optimize for Auditability and Trust
One of the Guardian’s key features is the trust chain — a transparent record of every document, signature, and transaction. Design your policy with this in mind. Every submission, from project description to VCU issuance, should leave a verifiable trail.
7. Iterate and Compare
We continuously improve our policies. Guardian allows schema and policy comparisons between versions. In VM42 v2.1, we moved from a simplified scenario-based version to a fully parameterized, calculation-ready implementation — and the difference is measurable.
