1. “You never change things by
fighting the existing reality.
To change something, build
a new model that makes the
existing model obsolete.”
Buckminster Fuller

2. THE DECENTRALIZATION SINGULARITY

3. Prologue
A centralized, digital world

4. A Digital World
• % of population with Internet in the
developed world: ~90%
• 46,000 Google searches, 8,000 tweets,
1,600 Skype calls, 2M emails - per second
• 6 billion hours worth of videos are
watched on Youtube every month
• Amazon shipped 5 billion items in 2014
• Smartphones will introduce billions of new
Internet users from the developing world
very soon

5. • We’re still using the same ageing
infrastructure from the 70’s
• Promised decentralisation of the internet
never occurred
• Online more centralized than offline media:
• Facebook is 71% of all social media
• The 14 competitors to Amazon combined
only represent 1/5 of its capacity
• This centralisation was unintentional, is
convenient and allows for targeted
advertising
“Social media platforms are
public in the same way that a
shopping centre is”
Jamie Bartlett, telegraph.co.uk
Going Backwards

6. • Require you to entrust them with your
information and your funds
• Provide absolute power to ‘sharing
economy’ platforms
• Provide an inordinate amount of power
to app store providers
• Current monetization models lead to
privacy and data loss, abuses of power
and carelessness in handling user data,
regardless of regulations
• Are single point of failures exposing
small surfaces of attack
“The Web’s future
relies on individuals
owning their data”
Tim Berners-Lee
Centralized Models

10. Chapter 1
Ethereum

11. • An 100% open source software platform to build
and distribute decentralized applications
• No middle men, users are in control of their
funds and personal information at all times
• Can be used to build anything: social sites,
financial systems, voting mechanisms, in-game
economies, reputation systems
• 100% peer to peer, censorship-proof and
corruption-proof: data exists both everywhere
and nowhere in particular
What is Ethereum?

12. • A not for profit organisation whose goal
it to take the Internet to its logical
conclusion
• Agenda free: users leverage it because
they don’t have to trust it - it has no
agenda other than solving a problem,
and it is easily peer-reviewed.
• Through its pre-sale Ethereum secured
USD 18M, plans to launch a v1.0 March
2015
“Open source software is ideas created and shared for the common good”
The Ethereum Team

13. • Consensus at scale a notoriously hard problem to solve
• Ethereum makes it trivial to build on top of blockchain
technology
• Rather than low-level network protocol concern,
developers can focus on delivering true value to their
users

14. Centralized Decentralized
Blockwhat?

15. Implementation

16. Ethereum Contracts
• Blockchain technology where trust
is achieved on a open network
• Contracts as your applications
backends, maintained by the
network
• Zero Infrastructure

17. Technology Stack

18. Ethereum : A computer we all share

19. Chapter 2
Use Cases

20. • Anything can be build, but some use cases are
more compelling than others early on
• Reconciling the need for sharing without the
uncanny valley elements
• Decentralized Apps the true stars of the show
Build anything

21. Organisational
• Contracts (b2b)
• Assets permissions
• Shareholder agreements
• Prediction markets
• Voting systems
• Domain registries
Consumer
• Escrows
• Personal asset store
• Smart property
• Financial exchanges
• Savings accounts
• Wills
• Intellectual property
Smart Contracts
Peer to peer finance
• Crowdfunding
• Derivatives, hedging
• Insurance

22. • Eliminate ambiguity
• Entering is agreeing - no need to sign on the dotted line
• Provide flexibility - both in terms of ruleset and of state
• Allow for consumer protection to be included as part of code
Smart Contracts

23. • The end of rent-seeking behaviour
• Startups include:
• airlock.me
• MoneGraph
• Foodway
• CubeSpawn
• and many more! Project airlock.me demonstrating
their smart contract enabled door
Web 3.0
Cubespawn

24. • Privacy
• Security
• Scaling

26. • Contracts the perfect ledger to issue tokens of value
• A decentralized Kickstarter on Ethereum would
enable startups to issue shares
Issuing tokens of value

27. Truly reward early adopters

28. • Mesh networks
• Distributed computing

• Measurement of clean energy production
• Rewards for actions taken in the physical
world

89. Epilogue
Disruptive doesn’t begin to describe it

90. Community & Media
• Vitalik Buterin, winner World Technology Award
2015
• 97 meetups groups, 30 countries, 8k members
• Dozens of startup building apps on our platform
• 100k uniques on our site/month
Software
• Started November 2013
• 3 FOSS clients in C++, Go, Python
• Many more community clients in the
works: node.js , java, android, clojure,
objectiveC
The Story So Far

91. Let’s Predict the Future!

92. … applications were modular?
… the internet of things could self-heal?
… anyone could bootstrap a business and issue shares?
… the unbanked could have access to credit?
… access to financial instruments was universal?
… anyone could create their own currency?
… computer programs could employ humans?
… using the Internet didn’t require trust?
We’re about to find out.
What If
