“AI is behaviour by a machine that, if performed by a human being, would be called intelligent.”
[Minsky, 1975]
“AI is the study of how computers do things at which, at the moment, people are better.” [Rich and
Knight, 1991]

Fiddling with transactions is not possible, because everybody has a real-time copy of the database on
his/her computer
– All transactions are stored, so nobody can change items
– All actors in the network can check transactions
How a blockchain works
Blockchain application 1: cryptocurrency (BitCoin, Ripple, …)
bitcoin-blockchain, prevents that a bitcoin is spent twice: when you offer a bitcoin the receiving party
can check that you are the owner…
, Blockchain application 2: smart contracts
Automated contracts via blockchain
– Blockchain as trustmachine
– E.g. store property of a house on the blockchain
All transactions that require a third party to establish trust, could be registered (in principle) on a
blockchain – Could make transactions: cheaper, more efficient, safer, …
Applications: voting machines, registration of property, savings accounts, intellectual property,
crowdfunding platform, etc.
