5. World Economic Form
February 2016
The internet is driving a shift towards
networks and platform-based social and
economic models.
Assets can be shared, creating not just
new efficiencies but also whole new
business models and opportunities for
social self-organization. The blockchain,
an emerging technology, replaces the
need for third-party institutions to
provide trust for financial, contract and
voting activities.

6. A Blockchain is a
decentralized data
structure that allows
participants to transact
directly with each other
and stores the state and
history of participants’
transactions.

JUST LIKE THE INTERNET,
ALL OVER AGAIN
Just like the internet allows us to communicate in a direct and immediate
manner with minimum intermediaries,
Blockchain technology allows us to transact in a direct and immediate
manner, with minimum intermediaries, on a distributed trustless ledger.

“The term smart contract
can be so confusing.
Really it is just a self-
executing piece of code on
a distributed ledger.”

OF SMART CONTRACTS

24. Seite 24
SMART CONTRACTS
CHALLENGES
CAUTION Must not be designed so carelessly that new complexity is introduced
DANGERS It could prove very awkward, if not impossible, to unwind a feral smart contract given
the technology challenge for judges and arbitrators and any jurisdictional maze
CHALLENGE Getting the technology right and making it very very easy to use is the challenge
DETERMINISM Contracts should be the same, regardless of who looks at them and when
SMART CONTRACTS MUST BE SIMPLE TO UNDERSTAND AND EXECUTE!
