A copy of the blockchain is stored on each user’s computer.
It is the shared, collective history of transactions on the network.

OPEN SOURCE TRUST
“If I have more than $100 in my wallet, I’ll give $10 to Tom.”
People make promises, and sometimes break them.
if wallet.balance > 100 then money.giveTo(tom,10)

OPEN SOURCE TRUST
Open Source software can be seen and audited by anyone.

Contracts can be used to build currencies, financial derivatives, voting systems, decentralized organizations, data feeds, title
registries and thousands of other applications.
ETHEREUM IS VERSATILE
Sending a transaction to a contract causes its code to execute. Contracts can store data, send transactions and interact with
other contracts.
ETHER IS THE FUEL
The more computation a transaction requires the more ether it consumes.
NOT ALL CONTRACTS ARE ALIKE

USING CONTRACTS
Ethereum can be used to codify, decentralize, secure and trade almost anything.
