1. ethe reum
THE WEB, WITHOUT SERVERS

2. 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

6. Anything
USE CASES

7. BYE BYE MIDDLEMEN, YOU HAD YOUR FUN 1/2
• 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

8. BYE BYE MIDDLEMEN, YOU HAD YOUR FUN 2/2
Contracts the perfect ledger to issue tokens of value
Kickstarter offers you T-shirts, such an app on Ethereum would give you shares

9. NODE INCENTIVIZATION
Mesh networks
Distributed computing (BOINC, folding at home)
Measurement of clean energy production
Rewards for actions in the physical world

10. BRINGING REPUTATION BACK IN FINANCE

11. !
Could be machine-controled corporations
or simply autonomous coops
DAOS

12. MIST, THE ETHEREUM BROWSER

13. SCHELLING QUAKE DAPP

14. TRUSTLESS INSURANCE

15. MIST, THE ETHEREUM BROWSER
Reactive programming
Global pseudonymous single sign on

16. THE STORY SO FAR
Software
- Started November 2013
- 3 open source reference clients in C++, Go, Python
in proof of concept 7 stage
- Many more community clients in the works:
node.js , java, clojure, objectiveC
Community
- 81 meetups group worldwide, 6k members
- 100k uniques on our site/month
- 10k followers on twitter

17. ACCELERATING INNOVATION
Anyone can bootstrap a business through a kickstarter on steroids
Universal access to financial instruments
Reputation as a collateral
New paradigm of autonomous app components you can leverage
which vertical will be disrupted first?
