A block chain or

blockchain is a

distributed database,

introduced by Bitcoin

(2008) on Satoshi

Nakamoto’s white paper,

that maintains a

continuously-growing

list of data records that

each refer to previous

items on this list.

What is a Smart Contract

Smart contracts are computer protocols that facilitate, verify, or enforce the

negotiation or performance of a contract, or that make a contractual clause

unnecessary. Smart contracts often emulate the logic of contractual clauses

Bitcoin – Blockchain - Facts


Cryptocurrency

Bitcoin

HISTORY

FACTS AND MARKET SHARE

• The first wallet program was released in 2009 by Satoshi Nakamoto as open-source code

• Famous transaction is 10,000 BTC used to indirectly purchase two pizzas delivered by Papa John's

• On 6 August 2010, a major vulnerability in the bitcoin protocol was spotted but fixed with network split

• On 21 July 2017 miners locked-in a software upgrade referred to as Bitcoin Improvement Proposal (BIP) 91

Ethereum – Blockchain - Facts


Public Blockchain

Ethereum

– Open-source, public, blockchain-based distributed computing platform featuring smart contract (scripting) functionality

– It provides a decentralized Turing-complete virtual machine called EVM : Ethereum Virtual Machine, is the runtime environment for smart contracts in Ethereum

HISTORY

FACTS AND MARKET SHARE

• Ethereum was proposed in late 2013 by VitalikButerin

• The system went live on 30 July 2015

• In 2016 Ethereum was forked into two blockchains, as a result of the collapse of The DAO project, thereby creating Ethereum Classic

• Represent 29$ Billion Market share in the crypto-currency world (as August 2017)

• ETH is the currency used to fuel and make the smart-contract running

• Enterprise Ethereum Alliance (EEA) is offering a permissioned version of Ethereum for Enterprise

Hyperledger – Blockchain - Facts


Permissioned

Hyperledger

– Blockchain framework implementation and one of the Hyperledger projects hosted by The Linux Foundation

– Allows components, such as consensus and membership services, to be plug-and-play

– Leverages container technology to host smart contracts called “chaincode” that comprise the application logic of the system

HISTORY

MARKETS AND FACTS

•December 2015, the Linux Foundation announced the creation of the Hyperledger Project

• July 2017, the project announced its production-ready Hyperledger Fabric 1.0.

• Regroup more than 100 partners (IBM, Cisco, Hitachi, JPMorgan,Accenture …)

•Hyperledger is mostly used in enterprise and private blockchain

• There is no crypto-currency associated withHyperledger

Blockchain Key Principles


Blockchain

Transparency & Visibility - No one should be able to cover their tracks.

Privacy - Security should be afforded without giving up confidential information.

Scalability - Must be able to scale to trillions of digital assets and also transactions (not the case for public

blockchain for the moment).

Reduce Time to market : via smart-contract can be easy to make a P2P transaction

Accountability - Every action should be attributable to it’s owner.

Permanence - Security must not be ephemeral – it must exist as long as the data exists, and ideally longer.

Blockchain state in 2017


Cryptocurrency Market share exceed

$100Bn with more than 1’000 tokens

Rise of permissioned Blockchain

R3, IBM, Hyperledger and soon

Microsoft)

Regulator cannot ignore Blockchain and is

moving to regulate it (ICO warning by US

Securities SEC and China banned ICO)

ICOs (Initial Coin Offering) fund raising

exceed traditional Venture Capitals fund

(will exceed $1Bn by end of 2017)

A lot of startup try to innovate by

creating their own Blockchain (soon

will appear Blockchain of Blockchains !)

A lot of pilot project running with

government, private company (ELCA ☺)

using mainly Hyperledger, R3, EEA.

Use Cases

Blockchain use cases per industry


Use case : Combatting Fraud in Ticketing

©copyright 2017

Combating Fraud in Ticketing

Fraud Black marketBot buying tickets


Bots buy tickets faster than real fans. Tickets

that are then resold on the secondary market

at higher prices.

Some dealers lie on the spot category or even sell fake notes.

With the multiple resale and the redistribution of

tickets, one does not know who are the real

spectators.

―Send tickets to friends and family

―Allow resale at a regulated price

―Be sure to own a real ticket

Transfering Tickets using Wallet apps and Blockchain

Core Ticketing

Platformfeature

pack

40

OBJECTIVES

• Dematerialize ticket management for stand managers and employees to simplify processes

• Test the «100% mobile ticket experience» on a captive audience with minimum risk before extending it later to a wider audience subject to fraud

• Tickets used to be paper-based for the stand staff resulting in manual distribution, lack of visibility and suboptimal management of changes

SOLUTION

Technology stack

• Mobile app with smart wallet

• Private Blockchain Hyperledger

• Enhanced access control to allow the conversion of a mobile ticket into a bracelet

Constraint:

• Different attendance schedule for staff members across six days with last minute changes.

• Various maturity levels of mobile phone usage within target audience

FACTS & FIGURES

Target audience

200 managers of stands and their staff

Volumes

• 10,000 tickets spread across 200 stand managers

• 2,423 users

• 72% of tickets were transferred one time

• 8% of tickets were transferred more than 2 times and up to 5 times

RESULTS

• Good level of satisfaction from users although some assistance was required onsite

• 100% visibility on ticket allocation and status

• Successful ticket transfer and exchange

« No need for me to leave my stand and go to the main gate to hand over his ticket to each of my employees when they arrive. All it takes is a simple transfer ». (Stand manager)

« This is a great system! Out of 48 employees, only 2 required my help.» (Stand manager)

«This is very convenient. No more paperwork! We can even exchange tickets ». (Stand employee)

PALEO 2017 EDITION

Core Ticketing

Platformfeature

pack

41

OBJECTIVES

• Secure the mobile ticket

• First time that ever piloted the 100% mobile ticket equipped with a barcode

• Up until now, all tickets were paper-based and encrypted with holograms to prevent fraud

SOLUTION

Technology stack

• Mobile application with secure wallet

• Private Blockchain Hyperledger

• Two-step access control solution• Outer perimeter: HID + SecuTix• Inner perimeter: SecuTix access

control on the stadium’s turnstiles

Use Case

1. Ticket holder scans his m-ticket through the HID smart reader beacon at the outer perimeter

2. The system validates that the ticket holder is authorized.

3. The barcode materializes on the ticket. From that moment on, the ticket cannot be transferred anymore

4. The system retrieves complementary information from SecuTix and displays additional data on the ticket (seat #...)

5. Ticket holder enters the inner perimeter (stadium) by scanning his ticket at the access control

FACTS & FIGURES

Target audience

Audience of people in the general public who did not get a ticket through the lottery

Volumes

• 1055 fans were invited to purchase tickets

• 130 fans bought 188 tickets

• Tickets could be transferred to friends & relatives

• 156 fans had tickets

Ticket activation

92% were automatically activated without any manual intervention

RESULTS

Smooth and transparent experience for the end users with minimal onsite support required

Successful pilot proving that the mobile ticket works and meets strict security expectations.
