Information about the BFlow technology and its real-world demonstrations
BFlow is a lightweight, field-ready traceability and impact-tracking technology developed by Pollen Labs. It is designed to operate with minimal hardware requirements (e.g., smartphone + pre-printed QR codes), making it practical for real-world supply chains and environmental operations.
BFlow’s strength comes from the participation of independent partners across the supply chain. When each actor submits their own attestations, the dataset becomes decentralized, tamper-resistant and publicly auditable. Because all entries are transparently recorded on-chain, anyone can review quantities, sequences, or reported actions and manually verify the consistency and integrity of the process.
BFlow enables the recording, timestamping, and verification of actions across a distributed supply chain using attestations, transparency dashboards, and blockchain anchoring. It is built to support organizations aiming to operate transparently, especially in contexts where field conditions are challenging.
The Enaleia Hub is a real-world demonstration of BFlow in action. It was deployed as a service for Enaleia through the generous support of the Ethereum Foundation’s Next Billion Team, whose funding enabled its implementation and rollout to help showcase Enaleia’s marine plastic collection efforts and their environmental impact.
A walkthrough of the Enaleia Hub demonstration is available here: https://youtu.be/P9QTiQ37r1I This video explains the field workflow, operational design, and the technological approach behind BFlow.
BFlow was designed by Pollen Labs with the following principles: • Field practicality: low-tech, accessible, no specialized hardware • Operational clarity: simple workflows that require minimal training • Transparency by default: public verification and traceability • Inclusivity: adaptable to diverse actors, even in low-infrastructure environments • Environmental and social impact: enabling organizations to demonstrate real change
These principles also guided the creation of the Enaleia Hub instance and continue to guide BFlow’s evolution.
We welcome questions, collaborations, and proposals from organizations, large or small, who wish to implement transparent, accountable supply-chain tracking.
