Biotapes™
The Visual Evidence Standard for Nature Markets
Human-visible, hash-verified, timestamped baselines that bring trust to ecological reporting, BNG compliance and nature-finance projects.
WHAT IS BIOTAPES
Biotapes™ is a verified visual baseline protocol used to establish ground-truth evidence for ecological and nature-finance projects.
-
It combines:
- a standardised filming method
- automatic metadata embedding
- cryptographic hashing at ingest
- unique Biotapes Verification IDs
- lightweight API integration for platforms
Biotapes provides a neutral, independent way to prove what was on the ground, when it was filmed, and that the evidence hasn’t been manipulated.
It is a product of Purpose Built Films, bringing documentary-grade visual integrity into emerging nature markets.
WHY BIOTAPES MATTERS
Nature markets depend on trust - but baselines are often invisible, inconsistent, or unverifiable.
-
Biotapes solves this by providing:
- Transparency - clear, human-visible evidence
- Consistency - a repeatable filming protocol
- Security - hash-verified files that cannot be altered
- Accessibility - easy integration into any platform
- Neutrality - independent verification trusted by investors, insurers and regulators
Biotapes is designed to support BNG projects, natural capital markets, TNFD-aligned reporting, habitat banks, restoration finance, and NGOs.
HOW BIOTAPES WORKS
Capture
A simple, universal 3-angle filming protocol captures ecological baselines:
- establishing wide

Metadata
Each clip automatically embeds:
- GPS
- timestamp

Ingest + Hashing
Footage is passed through the Biotapes ingest layer, generating:

- Biotapes Verification ID
Storage
Partners store the file and ID in their systems.
