Over a 2-year project period, a series of public meetings and presentations at Indigenous-led conferences introduced the concept of exploring compatibility between blockchain and IDS principles, followed by iterative prototyping and co-design of a blockchain platform with NativeBio, using Ethereum as the underlying protocol.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n Direct engagement with NativeBio and the CAB informed the initial design and development of a \u201cb-IDS\u201d proof-of-concept (POC) blockchain platform. The POC consists of three main components: (1) the web front-end layer, (2) the Ethereum network that executes the smart contract and blockchain storage aspects of the framework, and (3) the back-end database that stores off-chain interactions and data for future use with external genomic data repositories. After refinement of the POC, a community-based participatory research (CBPR) use case aligned with IDS principles was identified as a practical workflow and incorporated into the design of the POC for implementation.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n The findings from this project demonstrated the potential use of operationalizing IDS through blockchain technology with proactive and sustained engagement with Indigenous partners. Blockchain technology may have certain advantages over other data governance approaches and systems, facilitating timely oversight, shared decision-making and consent structures, and direct involvement of Indigenous communities in technology design, respecting the core principles of IDS and CBPR. Future development of the blockchain-IDS POC will need to incorporate other research practices and ethics frameworks to expand its use to other public health and biomedical research use cases.<\/jats:p>\n <\/jats:sec>","DOI":"10.2196\/90247","type":"journal-article","created":{"date-parts":[[2026,7,28]],"date-time":"2026-07-28T19:27:25Z","timestamp":1785266845000},"page":"e90247-e90247","source":"Crossref","is-referenced-by-count":1,"title":["Development of a Blockchain-Based Platform to Enable Indigenous Data Sovereignty and Shared Research Participation With Indigenous Communities: Technology Prototyping and Community Engagement Study"],"prefix":"10.2196","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2191-7833","authenticated-orcid":false,"given":"Tim","family":"Mackey","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1348-9717","authenticated-orcid":false,"given":"Alec J","family":"Calac","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1964-5549","authenticated-orcid":false,"given":"Tiana J","family":"McMann","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1818-2749","authenticated-orcid":false,"given":"Ken","family":"Miyachi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9843-2845","authenticated-orcid":false,"given":"Samm","family":"Hurst","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4215-5273","authenticated-orcid":false,"given":"Keolu","family":"Fox","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-9930-3952","authenticated-orcid":false,"given":"Burt","family":"Dillabaugh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1009-0615","authenticated-orcid":false,"given":"Kelle","family":"Dhein","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-1749-8232","authenticated-orcid":false,"given":"Guthrie","family":"Ducheneaux","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0691-8504","authenticated-orcid":false,"given":"Joe","family":"Yracheta","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1010","published-online":{"date-parts":[[2026,7,28]]},"reference":[{"issue":"1","key":"R1","doi-asserted-by":"publisher","DOI":"10.1186\/s12916-019-1296-7","article-title":"\u201cFit-for-purpose?\u2019\u2014Challenges and opportunities for applications of blockchain technology in the future of healthcare","volume":"17","author":"Mackey","journal-title":"BMC Med"},{"issue":"4","key":"R2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0266462","article-title":"Blockchain technology in healthcare: a systematic review","volume":"17","author":"Saeed","journal-title":"PLoS One"},{"issue":"6","key":"R3","doi-asserted-by":"publisher","first-page":"1211","DOI":"10.1093\/jamia\/ocx068","article-title":"Blockchain distributed ledger technologies for biomedical and health care applications","volume":"24","author":"Kuo","journal-title":"J Am Med Inform Assoc"},{"issue":"3","key":"R4","volume":"20","author":"AbdelSalam","journal-title":"Perspect Health Inf Manag"},{"issue":"3","key":"R5","doi-asserted-by":"publisher","first-page":"102535","DOI":"10.1016\/j.ipm.2021.102535","article-title":"hOCBS: a privacy-preserving blockchain framework for healthcare data leveraging an on-chain and off-chain system design","volume":"58","author":"Miyachi","journal-title":"Inf Process Manag"},{"issue":"11","key":"R6","doi-asserted-by":"publisher","first-page":"909","DOI":"10.1038\/s42256-022-00551-y","article-title":"Federated learning and Indigenous genomic data sovereignty","volume":"4","author":"Boscarino","journal-title":"Nat Mach Intell"},{"issue":"1","key":"R7","doi-asserted-by":"publisher","DOI":"10.1038\/s41746-025-01902-w","article-title":"A systematic review of responsible stewardship of research and health data from Indigenous communities","volume":"8","author":"Calac","journal-title":"NPJ Digit Med"},{"issue":"6674","key":"R8","doi-asserted-by":"publisher","DOI":"10.1126\/science.adl4664","article-title":"Indigenous data sovereignty\u2014a new take on an old theme","volume":"382","author":"Kukutai","journal-title":"Science"},{"key":"R9","unstructured":"Native BioData-Consortium.
