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

PrologueA centralized, digital world

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

• 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

• 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

Chapter 1Ethereum
![Page 11: Ethereum Paris w/ Stephan Tual](https://reader037.fdocuments.in/reader037/viewer/2022110122/55a5172e1a28abe27f8b46e8/html5/thumbnails/11.jpg)
• 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?
![Page 12: Ethereum Paris w/ Stephan Tual](https://reader037.fdocuments.in/reader037/viewer/2022110122/55a5172e1a28abe27f8b46e8/html5/thumbnails/12.jpg)
• 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
![Page 13: Ethereum Paris w/ Stephan Tual](https://reader037.fdocuments.in/reader037/viewer/2022110122/55a5172e1a28abe27f8b46e8/html5/thumbnails/13.jpg)
• 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
How do I build on Ethereum?
DAPP
HTML + JAVASCRIPT (FRONTEND)
SOLIDITY (C++/JS) OR
SERPENT (PYTHON)(BACKEND)

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

• Reconciling the need for sharing without the uncanny valley elements
• Decentralized Apps the true stars of the show
