The Ancient BioChain is a full working BioChain, applied to publicly available research data. It begins with ancient DNA. Ancient DNA provides an unusually demanding provenance problem, because one ancient individual can accumulate a research history spanning decades, institutions and technologies.
It runs all five steps — connect, structure, link, authenticate and verify. Access to the chain itself is arranged through a demo.
Private BioChain deployments run inside organisations' own systems, under their own confidentiality obligations — that's the point of the architecture, and it means we can't publish client case studies. The Ancient BioChain exists to close that gap: the same provenance architecture, applied to publicly available research data, running in the open where anyone can see it work.
Excavation. Curation. Sampling. DNA extraction. Library preparation. Sequencing. Bioinformatics. Publication. Repository. Re-curation. The Ancient BioChain preserves those relationships while allowing gaps, corrections and subsequent interpretations to remain part of the history.
