Encryption
It’s not a database !
Types of Networks
traditional systems
Seperate ’stacks’, seperate databases
Incoherenceof data
‘Blockchained’
’stacks’ met gedeelde blockchain componenten
OPEN Public Blockchains Permissioned enterprise Blockchains

MULTIPLE DEPARTMENTS
START WITH A ‘FEW’ NODES
GROW NETWORK – ADD MORE NODES
INCREASE DECENTRALIZATION
MULTIPLE FUNCTIONALITIES
START WITH ‘ONE’ FUNCTION – E.G. Simple Asset registration
Grow application – more complex smart contracts
INCREASE automation
