AETHEREUM

Blockchain is a technologiy to reach trust on an open network. ("Block chains are used to establish decentralized consensus among computer systems")

Anything that can be mathematically represented can be modeled, secured and traded.

Personal information, identities and core data stay in your control.

Aethereum is based on contracts, programs that transparently deal among each other based on sequences of predefined steps.

Reputation in the network is the key for value.

You get bad reputation if your program doesn't behave as expected by the network and or if it provides mismatching data.
