Tracking Living Parts: Blockchain for Biomaterial Provenance
Every printed tissue starts with donated cells and a chain of custody. Could a tamper-evident ledger make that chain more trustworthy?
A printed tissue carries a long history: who donated the cells, what consent they gave, how cells were grown, which bioink lot was used, what the printer did, and every quality test along the way. In regulated medicine, that history must be airtight.
What blockchain could add
- Tamper-evident records: each step is hashed and time-stamped, so edits after the fact are detectable.
- Consent tracking: donors could see, and potentially revoke, how their cells are used.
- Shared data across labs: multiple organizations can write to a common record without one party controlling it.
- Print file integrity: hashing the design file ensures the part printed is the part approved.
The honest caveats
Most of this can also be done with well-run conventional databases and digital signatures. Blockchain adds value mainly where several organizations that don’t fully trust each other need a shared record. Patient data privacy rules also mean sensitive data should stay off-chain, with only hashes on-chain.
