Our P2P platform is free, borderless, and open-source, and is built upon Blockchain technology to collect and deliver human biosignals to researchers, labs, and entities that need biosignal data in a trusted and secure manner while respecting the privacy of participants and the ownership of data by research institutions. The key feature of Zarela is Proof-of-Contribution (PoC), which enables a volunteer participant (Angel) and biosignal requester (Mage) to exchange data anonymously throughout the Blockchain network.
