Differentiator Benefits for our clients
Vendor Neutral
We have assessed all major platforms in terms of their strengths, weaknesses and
nuances.
Devops-for-DLT
We have wrapped key DLT platforms in devops toolkits to ensure easy and repeatable
installation.
Methodology
We created a bunch of Proof-Of-Concept to be experienced with Blockchain in
practice. We do research on the early stages with focusing on practical use cases.
Community
We have engaged with the community and early adopters - our group CTO is Vice
President of the CryptoValley Association in Zug.
Partnerships
We have fostered official partnerships with various complementary consulting
companies and key vendors.
Advanced
Technologies
Blockchain is just one of many technology areas we have deep experience of, we do
not restrict ourselves to one area of expertise.
4. Luxoft are currently working with scientists and core developers of different Blockchain platforms.
Our team are continually researching Blockchain platforms’ reliability, safety, stability and attack-resistance. Using the power of
supercomputer, we are simulating difficult use cases, observing platforms’ behavior in long-term usage, gathering statistics and
assessing Blockchain’s applicability in different areas, such as Internet of Things, Healthcare, Finance and others.

7. Challenges Overview
7
The theme for our hackathon is to apply
blockchain to newer and wider industries.
We invite participants to come and work
with our expert mentors to leverage
Blockchain and its unique combination of
immutability, strong encryption and data
sharing to create innovative and disruptive
solutions in the themes of :
Education
Healthcare
Smart mobility
8. Education
8
Education is one of the most significant parts of our life and forms the foundations for who we
are. The education ecosystem is inefficient and often inflexible. In the Smart City of the future we will be
creating education processes that will be transparent and modern. There are many areas that could be
tackled, and we list some examples below, but you are not limited to these areas in your thinking:
Education
DEVELOPMENT
How could Admission to a School or University be automated?
How can sponsorship programs and investor’s commitment to a
student be monitored?
SECONDARY SCHOOL

9. Healthcare
9
Healthcare is one of the fundamental services throughout one’s life. For the healthcare challenge we
would like you to consider how to create an innovative and connected healthcare ecosystem. You can
consider any and all processes around people are related from health monitoring to health services supply
services.
Some suggested problems to get you thinking:
Electronic Health stability monitors (from birth)
Insurance companies that provide insurance schemes that
dynamically depend on a patient’s activities and location;
Citizen lifestyle monitoring that can determine care services;
All visits to physicians are shared between the clinics;
CITIZEN CARE
CARD
COMPLAINT
HISTORY
LIFESTYLE
MONITORING
SUPPLY
SERVICES
10. Smart Mobility
10
City mobility brings many benefits to citizens. Imagine if modes of transport could communicate
with the city, be that vehicle-to-vehicle, services to vehicle or perhaps insurance with the police. This has the
possibility to make the city safer and faster and ultimately improve the quality of life for its citizens.
Some suggested topics are
Vehicle-to-vehicle communication
Traffic lights to collect statistics and make decisions;
Drivers to get compensation for giving way if asked;
Crowdfunding (flights, car sharing, etc.)
11. Submissions
The judging will be based on the amount of innovation in your solution, both from a
technical perspective but also from a social perspective – how will society benefit from
your solution?
At the end of the hackathon, you will be expected to present your solution, and you
should include:
What problem does your solution solve?
What is the technical architecture?
What benefits will your solution bring to society?

Ethereum Skeletons and Test Applications
Demo application is written on JS. App uses web3 SDK to connect to the
Network. Application demonstrates Smart Contract deployment, calling update
and constant members, and waiting for events.
Gradle project for Demo App is written on Java. App uses web3j SDK to
connect to the Network.
Auto-generated Smart Contract classes will be placed here after build
Smart Contract Compilers for Win, MacOS, Linux
Gradle configuration scripts. Build.gradle depends on solidity.gradle. Solidity
script builds sources and places auto-generated files under the
buildgenerated-sourcessolidity folder
Source codes: Java + Smart Contract
Ethereum test wallet
The easiest way to start development is to open Gradle project in any IDE.
The wallet file should be put into skeletonsrcresources directory. If balance is required, please, contact support team.
Shared Hackathon network can be used for development and release purposes.
18. Fabric Network Topology
MY-CHANNEL
ORGANIZATION#1
ORDERER
1. Peers’ keys verified and signed by Organization#1 (by CA
department); Peers belongs to the Organization#1;
If more Peers are required certificate should be created;
2. Users are authorized by Organization#1 and gets enrolment
certificates;
3. Orderer has certificate of Organization#1 to verify Peers and
Users;
4. Transaction is sent to Endorser Peers and after getting enough
confirmations will be send to the Orderer;
Suggested Fabric Network consists of 3 Peers joined to the single
Channel.
If more Channels are required than configtx.yaml should be modified;
