is it based and how it works. Marks: 4

3. Which features distinguish databases from blockchain ledgers?

Provide a comparative analysis of the two. Marks: 5

its main characteristics, and explain how it differs from a “traditional”

centralized ledger. Marks: 5

5. Suggest which type of blockchain should be used for the security of

donations in a charity organization. What benefits does the

blockchain technology introduce in such a scenario? Explain your

answer using an example. Marks: 5

6. Explain how blockchain can be introduced in the education system to

certify the credentials of candidate teachers and ascertain the

security of the pupils’ personal data. Marks: 5

7. Critically present and compare how smart contracts can be used in a

lottery scenario. Marks: 4

8. How does blockchain technology prevent/ solve the problem of

“Double spending” in digital currencies such as Bitcoin? Marks: 3

imagined. (tokenization)

4. Explain why a Smart Contract execution has a cost. Marks: 5

5. In a few years, it’s possible that we will use an Ethereum Smart

Contract to seal the union of two people. Imagine what features we

could associate with this contract (For example: joint account, saving

account, divorce proceedings, property management, …) Marks: 10

Work assignment (1)

Learning objectives

1. Enhance the understanding of collaborative system and blockchain

usage, fitting a pre-project description

2. Understand how such a blockchain project can be organised,

identifying the global ecosystem and its financial part

Tasks to do:

1. The company you work for is considering introducing blockchain

technology to support a collaborative on-demand energy supply

organisation. You are asked to present opportunities and risks

associated to this strategy. First of all, explain to your colleague why

a Blockchain can be seen as a missing element of the Internet

communication stack to support a distributed collaborative

organisation, managing stakeholders’’ interactions. Marks: 4

2. The collaborative organization operates in a very competitive

environment. Which business model fits this context and identify the

blockchain organisation (permissioned vs permissionless). Marks: 4

3. How can a blockchain help fitting the legal constraints to manage

relationships between stakeholders? Marks: 4

4. Your collaborative industrial organisation aims at connecting IoT

devices to have more efficient energy production process / energy

consumption coordination. Explain how smart contracts can provide

a support to design the collaborative process organisation. Marks: 4

5. Explain why a Smart Contract execution has a cost. Marks: 5

Work assignment (2)

Learning objectives

1. Enhance the understanding of essential blockchain ecosystem main

characteristics

2. Motivate a blockchain ecosystem organisation within a given scenario

3. Evaluate the financial part of a blockchain project

Tasks to do:

1. The company you work for is considering introducing blockchain

technology to support a collaborative energy production

organisation, including final customers that also may be energy

producers at the same time. The energy grid management process

interconnects IoT devices associated to the energy production /

consumption devices as well as energy producers’ information

system. The goal of the project is (1) prefer a local production for

energy consumption, (2) manage exchange with other energy actors

to sell / buy energy depending on the demand. You are asked to

present opportunities and risks associated to this strategy. Identify

the collaborative organisation. To this end, identify different

stakeholders and set a diagram showing their interactions and define

for each stakeholder the value criteria associated to the project.

Marks: 4

2. Which blockchain will you use to support this project? Marks: 4

3. As the main goal of the collaborative energy supply organisation

consists in an improved management of the energy, choose a

transaction validation strategy. Please justify your choice. Marks: 4

4. To set the support Blockchain, identify the blockchain organisation,

and the potential new partners, using the Deloitte stack. For each

partner identify the value he provides? Marks: 4

5. To support this project, identify the token status and the related

constraints to organise the associated initial token offering. Marks:
