But first, a bit of theory Lab and Blockchain

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

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

Blockchain Technology

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

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

Central vs Decentral

But also: decentralised

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

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

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

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

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)

Prototype

Plug & Play

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

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

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
