1. โYou never change things by
๏ฌghting the existing reality. โจ
To change something, build
a new model that makes the
existing model obsolete.โ
โจ
Buckminster Fuller
4. A Digital World
โข % of population with Internet in the
developed world: ~90%
โข 46,000 Google searches, 8,000 tweets,
1,600 Skype calls, 2M emails - per second
โข 6 billion hours worth of videos are
watched on Youtube every month
โข Amazon shipped 5 billion items in 2014
โข Smartphones will introduce billions of new
Internet users from the developing world
very soon
5. โข Weโre still using the same ageing
infrastructure from the 70โs
โข Promised decentralisation of the internet
never occurred
โข Online more centralized than offline media:
โข Facebook is 71% of all social media
โข The 14 competitors to Amazon combined
only represent 1/5 of its capacity
โข This centralisation was unintentional, is
convenient and allows for targeted
advertising
โSocial media platforms are
public in the same way that a
shopping centre isโ

Going Backwards
6. โข Require you to entrust them with your
information and your funds
โข Provide absolute power to โsharing
economyโ platforms
โข Provide an inordinate amount of power
to app store providers
โข Current monetization models lead to
privacy and data loss, abuses of power
and carelessness in handling user data,
regardless of regulations
โข Are single point of failures exposing
small surfaces of attack
โThe Webโs future
relies on individuals
owning their dataโ โจ
Tim Berners-Lee
Centralized Models
9. Just 3% of respondents said they trust social networks with their data
Open-xchange - Crossing the Line Report
86% of Internet users have taken steps to avoid surveillance
Pew Research Center's Internet Project & Carnegie Mellon University
88% of ICT decision-makers report that they are changing their cloud buying
behavior as a result of Snowdenโs leaks
NTT Communicationsโ survey
A Data Trust De๏ฌcit
11. โข An 100% open source software platform to build
and distribute decentralized applications
โข No middle men, users are in control of their
funds and personal information at all times
โข Can be used to build anything: social sites,
๏ฌnancial systems, voting mechanisms, in-game
economies, reputation systems
โข 100% peer to peer, censorship-proof and
corruption-proof: data exists both everywhere
and nowhere in particular
What is Ethereum?
12. โข A not for pro๏ฌt organisation whose goal
it to take the Internet to its logical
conclusion
โข Agenda free: users leverage it because
they donโt have to trust it - it has no
agenda other than solving a problem,
and it is easily peer-reviewed.
โข Through its pre-sale Ethereum secured
USD 18M, plans to launch a v1.0 March
2015
โOpen source software is ideas created and shared for the common goodโ
The Ethereum Team
13. โข Consensus at scale a notoriously hard problem to solve
โข Ethereum makes it trivial to build on top of blockchain
technology
โข Rather than low-level network protocol concern,
developers can focus on delivering true value to their
users
How do I build on Ethereum?
DAPP
HTML + JAVASCRIPT
(FRONTEND)
SOLIDITY (C++/JS)
OR
SERPENT (PYTHON)
(BACKEND)
16. Ethereum Contracts
โข Blockchain technology where trust
is achieved on a open network
โข Contracts as your applications
backends, maintained by the
network
โข Zero Infrastructure
20. โข Anything can be build, but some use cases are
more compelling than others early on
โข Reconciling the need for sharing without the
uncanny valley elements
โข Decentralized Apps the true stars of the show
Build anything
22. โข Eliminate ambiguity
โข Entering is agreeing - no need to sign on the dotted line
โข Provide flexibility - both in terms of ruleset and of state
โข Allow for consumer protection to be included as part of code
Smart Contracts
23. โข The end of rent-seeking behaviour
โข Startups include:
โข airlock.me
โข MoneGraph
โข Foodway
โข CubeSpawn
โข and many more! Project airlock.me demonstrating
their smart contract enabled door
Web 3.0
Cubespawn
26. โข Contracts the perfect ledger to issue tokens of value
โข A decentralized Kickstarter on Ethereum would
enable startups to issue shares
Issuing tokens of value
28. โข Mesh networks
โข Distributed computing โจ
(BOINC, Folding @ home)
โข Measurement of clean energy production
โข Rewards for actions taken in the physical
world
Node Incentivization
90. Community & Media
โข Vitalik Buterin, winner World Technology Award
2015
โข 97 meetups groups, 30 countries, 8k members
โข Dozens of startup building apps on our platform
โข 100k uniques on our site/month
Software
โข Started November 2013
โข 3 FOSS clients in C++, Go, Python
โข Many more community clients in the
works: node.js , java, android, clojure,
objectiveC
The Story So Far
92. โฆ applications were modular?
โฆ the internet of things could self-heal?
โฆ anyone could bootstrap a business and issue shares?
โฆ the unbanked could have access to credit?
โฆ access to ๏ฌnancial instruments was universal?
โฆ anyone could create their own currency?
โฆ computer programs could employ humans?
โฆ using the Internet didnโt require trust?
Weโre about to ๏ฌnd out.
