This document discusses the potential of blockchain technology and shared ledgers to establish trust and truth in digital systems. It explores how humans perceive reality and form social order, and proposes that blockchain allows for a shared concept of truth through distributed, immutable ledgers. Several use cases are presented, including skill certification and building renovation records. The document promotes collaboration to further develop blockchain applications and build trust between organizations.

12. The Outer world

How do we perceive the outside world?
(Let’s not be skeptical and assume reality exists)
Brain-power
Memory - Experience
(Logical) Processing
“We form a projection
of Reality”

13. The Concept of Time
How do we measure time?
PresentPast Future
How do we perceive time?
As if only the present exists in reality !
“It is in you,
I say that I measure time.
As things pass by,
they leave an impression in you”

We rely on our memory and senses to form a projection of reality.

How do we form social orders togerther with other humans?
Getting information from those we trust
Forming your own competence / power hierarchies

a mechanism to draw
fact-based conclusions
In an auditable way”

20. The Pollution of ’Blockchain’
What is meant by the word ‘Blockchain’ by other?
The concept that a third party is no longer needed
The network of different nodes, working together
The technology needed to create such a network
The structure how transactions are ordered and linked

21. Data Model of a Ledger

Distributed Blockchain – BigChainDB
Directed Acyclic Graphs - Iota
Everyone has a full node / copy
Only one sequence is the absolute truth
History of Transactions is distributed

28. … blockchain READY!
MULTIPLE DEPARTMENTS
START WITHA ‘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

29. The ‘Monetizing’ Stone

30. Public Enterprise
Create a ‘Dapp’
Smart Contract
Use existing ‘trust’
APP Settle on a business case
Build a ‘Pure’ consortium
Build a blockchain network
Build an application & Integration
Create ‘Trust’

31. Enterprise

32. Governance !
How will updates occur to the consortium ?
How will a new partner join ?
Who will maintain the ledger / blockchain ?
Who will host the infrastructure ?
How to collaborate ?

you start solving people's problems”

34. Blockchain Project
Competence Pass

35. The Registration of competence in a safe manner
The Ownership remains with the individual
A platform that works with existing standards
Making a bridge between these different standards

36. TOM
Tom has quit his studies before he graduated.
Luckily, the ‘learning goals’ he achieved were
stored on the competence blockchain application
by the IXZO! platform
There are – in 2016 alone – over 5621
“non-qualified” highschool dropout in Flanders.
34,4% of them are looking for a job.
Tom De Wit

37. GOALS
Via IXZO! Tom can view exactly which goals he
gained / achieved during his education,
and which are his strengths and weaknesses.
All the achieved ‘learning goals’ are safely
registered on the Competence Blockchain
application.
