THE WEB, WITHOUT SERVERS

WHY ETHEREUM?
• What happens when you use a centralised service?
• Where else does this apply to us as users? As developers?
• Centralised models are single point of failures that you have to
put your trust into.
“The Web’s future relies on individuals owning their data” - Tim Berners-Lee

3.
WHAT IS ETHEREUM?
• An 100% open source platform to build and distribute
decentralized applications
!
• No middle men
!
• Social sites, Financial systems, Voting mechanisms, Games,
Reputation Systems
!
• 100% peer to peer, censorship-proof
!
• All nodes validate the network at all times, coming into
consensus
!
• Users stay in control of their funds and information at all times
== THE WEB, WITHOUT THE SERVERS

4.
HOW DO I BUILD ON ETHEREUM?
• Consensus at scale a
notoriously hard problem to
solve
!
• Ethereum makes it trivial to build
on top of such a platform
!
• Ethereum raised USD 18m and
plans to release in q1 of next
year

5.
HOW DOES IT WORK?
Blockchain technology where trust is achieved on a open network
!
Contracts as your applications backends, maintained by the network
!
Zero infrastructure and impervious to denial of service attacks

• IBM Adept IoT validation
