7. Artificial intelligence
AI is concerned with two basic ideas

- Representing & duplicating these processes via machines
AI is behavior by a machine that, if performed by a human being, would be called intelligent
AI is the study of how computers do things at which, at the moment, people are better
8. Blockchain
Shared digital database, used by a network of actors, to specify contracts or transactions
, 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
Bitcoin-blockchain prevents that a bitcoin is spent twice: when you offer a bitcoin the receiving party
can check that you are the owner
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.
