3. But first, a bit of theory
Lab and Blockchain

4. Blockchain network | Bitcoin
All members have a copy of the ledger

5. What is blockchain? A decentral bookkeeping of transactions
A network with thousands of computers
Every member has a copy of the ledger
No centralized server / owner

6. Blockchain Technology

7. Blockchain Properties
Each block is recalculated, not modifiable
Not crackable
Redundant
Scalable
Transparent, open
Indelible

8. Smart contracts Program code (appointments) recorded on the blockchain
Can regulate transactions, manage permissions, responsibilities and voting

9. Central vs Decentral

10. But also: decentralised

11. Applications Financial: Value transfer Legal: Contracts
Social: Voting, decentralised democracy
Cultural: journalism (Capturing IP, tracking sources etc.)

12. Medical applications Transfer of value Permissions (smart contract)
Decentralised storage
Availability
Traceability

13. Advantages for labs Unique registration credentials Readily available
Data access in each cabinet
No typo errors
80% cost savings

14. Challenges Integration of IT systems Maturity of blockchain software
Trust of hospitals

15. Small steps A small network of 8 mini PCs with their own blockchain
Distribute encrypted HL7 messages
Tracking a trace
Sending analyses (pdf)
Anonymised (no patient data about it network)

16. Prototype

17. Plug & Play

18. Labchain box Mini-computer with Linux OS Affordable Optional dongle
Fully open-source
Encrypted where necessary
Distributes lab values & files (p2p)

19. Labchain network
Decentralised network of min 10 boxes spread in the Netherlands
Private blockchain network
Every computer ‘knows’ all others
Private keys control authorization

20. Further targets Labchain in every Dutch hospital
Patient takes charge of personal data (available everywhere)
Basis for scientific research
Legal frameworks (ownership question)
Open source community
