5. CUTTING THE
MIDDLEMAN
Blockchain technology makes middlemen (so-called trusted
third parties) obsolete in many applications. Bitcoin can
serve as an example here. Bitcoins are not routed via a
central instance, e.g. a bank, but can be transferred directly
between the parties.

6. KEY FEATURES OF THE
TECHNOLOGY
•A public blockchain has some characteristic features:
•Write-only, immutable, transparent data storage.
•Decentralized, no need for intermediaries.
•Consistent state across all participants.
•Resistant against malicious participants.
•Open to everyone.

7. CHALLENGES FACED

OF CHALLENGES, DUE THE DIFFERENT VIEWS AT
THE GOVERNENCE LEVEL, AS THEY SUSPECT
ILLEGAL TRANSECTIONS AND TAX EVASION.
