How to read these records
Different kinds of evidence
Funding, publications and milestone acceptance answer different questions. Shared repositories may include non-Zcash work.
Coverage, not a score
Missing links do not establish inactivity or non-delivery. Dates show the source snapshot, not a live feed.
Shared funding
An award can appear across several projects. Inspect its scope before comparing amounts.
