Introduction of Ethereum

9. Ethereum
9
Ethereum was built to extend the blockchain concept with the ability to also run smart
contracts using a decentralised network, creating a globally distributed World Computer
Think of Ethereum as a world computer.
What Bitcoin does for payments, Ethereum does for
anything that can be programmed.
Vitalik Buterin, Ethereum Inventor
“
”
Ethereum value proposition
● Builds on the Blockchain concepts of cryptographic
security, decentralisation and immutability
● Adds in the capability to run veridical business logic (i.e.
decentralised smart contracts), a Turing complete
programming language running in the Ethereum
Virtual Machine
● With the establishment of the Enterprise Ethereum
Alliance, Ethereum is becoming the de-facto blockchain
technology of choice for enterprise projects, supporting
private permissioning and additional privacy features
while maintaining interoperability with the public
chain

10. The Ethereum advantage
10
Ethereum is the only blockchain infrastructure with a built-in Turing-complete virtual
machine within the full security of the blockchain protocol
Enterprise Ethereum Alliance
(EEA) is growing faster than all
other blockchain consortia
Public – private
blockchains compatibility
The dominant platform
for the 'token ecosystem’
Vendor-neutral
Rapidly growing
community
encompassing 30,000+
developers
Formally specified security
and smart contract
capabilities
