Ekos BioCredita

Overview

Ekos BioCredita is a biodiversity credit programme operated by Ekos in New Zealand and built on the Ekos SD Standard. It enables terrestrial and marine conservation projects to raise funding, with each project using or developing an activity methodology that is independently validated to the standard and then verified through monitoring reports over a project period such as 30 years. Credits are issued as Sustainable Development Units on the Ekos SD Registry, and each unit represents a verified biodiversity outcome such as area of habitat protected or restored. The programme states it is validated to the High Level Principles of the Biodiversity Credit Alliance, World Economic Forum, and International Advisory Panel on Biodiversity Credits.

01 · Roles

The workflow as an explicit directed graph. In Graph each column is one role, so you can see who acts at each step; every node names the org.broadlistening.policy.block.* def it resolves to plus its input and output record. Data flow switches to a lineage view that makes explicit what data each node needs and makes, with dependency arcs tracing every record back to the node that produced it, including where the Darwin Core occurrence + measurement records feed in. Hover to trace, click to inspect; revise edges (dashed) send work back.

03 · Generated lexicon records

The records this methodology compiles to, ready to write to a PDS. The first tabs are the new policy engine records; the ★ claim.activity tab and those after it are reused ATProto Collective Funding Ecosystem records (org.hypercerts.*): the issued hypercert batch, its rights, an example verification attachment and a retirement receipt. The ◈ dwc.occurrence and ◈ dwc.measurement tabs are the Darwin Core field evidence the monitoring node writes; see the section below.
