Decentralized biobanking \u201cde-bi\u201d applies non-fungible tokens (NFTs) to empower privacy-preserving specimen tracking and data sharing for networks of scientists, donors, and physicians. We design, develop, and demonstrate a functional de-bi platform for a real-world organoid biobank.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Ethnography of the organoid biobanking ecosystem was performed in 2022\u20132023, with site visits, interviews, focus groups, and structured observations of stakeholder interactions. An initial ERC-721 prototype was developed and tested, informing the design of a comprehensive NFT model. Web and mobile app prototypes were developed with a suite of ERC-1155 protocols representing ecosystem constituents as NFTs. We demonstrated the platform with publicly available Human Cancer Models Initiatives organoids to establish proof-of-concept for decentralized biobanking as the foundation of a democratized biomedical metaverse, or \u201cbiomediverse.\u201d<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Scientists revealed key challenges for organoid research and development under policy, scientific, and economic constraints of the life science landscape. We advanced decentralized biobanking as a blockchain overlay network solution with potential to overcome barriers, enhance utility and unlock value by uniting collaborators in a privacy-preserving biomediverse. Dedicated smart contracts created \u201csoulbound\u201d NFTs as de-identified digital twins of patients, physicians, and scientists in a networked organoid ecosystem. We modeled biospecimen collection, processing, and distribution, including generation and expansion of organoids, via an auditable on-chain mechanism. Key features included the ability to bootstrap the digital twin NFT model onto an established organoid biobank, visibility of patient-linked biospecimens and related research activities for all ecosystem participants, as well as tooling for multisided data exchange. Implementing de-bi with ERC-1155 showed potential to minimize gas costs of on-chain activity vs ERC-721, though complementary layer-2 solutions will be essential for economic viability.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Decentralized biobanking has the potential to enhance efficiency, increase translational impact and drive research discovery through implementation of NFT digital twins for organoid research networks. Importantly, this approach also bolsters ethical practices by fostering inclusion, ensuring transparency, and enhancing accountability across the research ecosystem. Next steps include live pilot testing, market design research to align stakeholder incentives, and technical solutions to support a sustainable, scalable and mutually rewarding biomediverse.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fbloc.2025.1510429","type":"journal-article","created":{"date-parts":[[2025,7,2]],"date-time":"2025-07-02T05:53:02Z","timestamp":1751435582000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["Decentralized biobanking platform for organoid research networks"],"prefix":"10.3389","volume":"8","author":[{"given":"Marielle","family":"Gross","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ananya","family":"Dewan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mario","family":"Macis","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eve","family":"Budd","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Eifler","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olayinka","family":"Odeniran","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeff","family":"Kahn","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert Clell","family":"Miller","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"William","family":"Sanchez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,7,2]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"840","DOI":"10.1109\/tdsc.2016.2616861","article-title":"Security and privacy in decentralized energy trading through Multi-Signatures, blockchain and anonymous messaging streams","volume":"15","author":"Aitzhan","year":"2016","journal-title":"IEEE Trans. nn Secure Comput."},{"key":"B2","doi-asserted-by":"publisher","first-page":"4265","DOI":"10.3390\/s23094265","article-title":"BFT-IOMT: a Blockchain-Based trust mechanism to mitigate SyBiL Attack using fuzzy logic in the internet of medical things","volume":"23","author":"Ali","year":"2023","journal-title":"Sensors"},{"key":"B3","first-page":"401","article-title":"Smart contracts and NFTs: non-Fungible tokens as a core component of blockchain to be used as collectibles","volume-title":"Lecture notes on data engineering and communications technology","author":"Arora","year":"2021"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.3389\/fbloc.2022.846783","article-title":"Event-based supply chain network modeling: blockchain for good coffee","volume":"5","author":"Bager","year":"2022","journal-title":"Front.
