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

== THE WEB, WITHOUT THE SERVERS

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

• 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

HOW DO I BUILD ON ETHEREUM?

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

HOW DOES IT WORK?

Anything

USE CASES

• No more eBay outrageous fees • On a p2p system you have to bring true to

your users • Examples of Airlock the decentralised airbnb

and many more • Applicable to digital art, any smart property • IBM Adept IoT validation
