Naar aanleiding van de publicatie van het boek "Blockchain Organiseren", organiseerde Lieve Vereycken (co-inpetto.org) een event met de auteur, Paul Bessems. Met de ondertitel "fundamenten voor een nieuwe sociaaleconomische orde", zorgde ik voor enige kadering vanuit de huidige orde :) Ook daar is men met blockchain en smart contracts aan de slag gegaan en wordt het enorme potentieel aangeboord. De bouwstenen voor een nieuwe orde zijn er, maar betekent dat een noodzakelijke afbraak van het huidige systeem?

9. Blockchain : a new paradigm

10. Blockchain : a technical definition
The blockchain is, from a technical point of view,
▪ A unique, public and transparent distributed ledger
▪ That stores all transactions immutably and
▪ Permits predefined actions on those transactions
▪ In a cryptographically secured environment.

11. Blockchain : a business definition
The blockchain is, from a business point of view,
▪ A shared platform
▪ On which parties who don’t know or trust each other
▪ Are able to collaborate with respect for privacy
▪ Without relying on a possibly corrupt administrator.

16. Ownership How value is stored
Nicki -> KoenIN 0,8 BTC
Wim -> KoenIN 0,6 BTC
Koen -> ThomasOUT 1 BTC
Wim -> KoenREST 0,4 BTC
Koen receives two payments
- 0,8 BTC from Nicki
- 0,6 BTC from Wim
Koen transfers 1 BTC to Thomas
- 0,8 BTC + 0,2 BTC
- 0,4 BTC is unspent transaction
• (A defined number of) assets are
stored on the blockchain
• Each asset is identified
• Assets are divided
• Assets are transferred (not copied)
=> Clear view on who owns what when.

27. The problem with smart contracts

28. Smart contracts : a definition
A smart contract is an agreement whose execution is both automated and enforceable.
• The actual “transaction” among parties is expressed through and independently
executed by computer code, no party can block it or otherwise tamper with.
• It constitutes legally binding rights and obligations of the involved parties.
Advantages:
• Parties are in consensus at all times as to the existence, nature and evolution of
the facts shared among them, which are governed by the program.
• Used to satisfy
• common contractual conditions,
• lower transaction costs and risk, and
• eliminate the need for trusted intermediaries.
