1. Project Overview
SupBank is an online European banking company focused on deposit accounts, overdraft, credit and
investment products. As with all existing banks, SupBank faces the limitations of the international SWIFT
and SEPA payment systems for international and European transfers.
In order to address the needs of its clients, SupBank has decided to create its own system for storing
and transmitting banking transaction information. This new system will have the following features:
Instant (nearly) wires
Fee-less foreign exchange
Decentralized
Tamper-proof and secure
Seamless transition for users
Full transaction history
During the launch process, the first available operation will be transfers between customers of the
bank. A set of subcontractors have been chosen, including you, to develop the best blockchain Proof
Of Concept.-

2. Functional Expression
The main goal of this first PoC is to allow transactions between users. User will be able to send funds
via their wallet application. Once the transaction has been validated by the user, the transaction will be
converted into tokens and then submitted for validation on the decentralized network of the blockchain.
A transaction is made of: A sender public address, a receiver public
A sender public address
Receiver public address (one or more)
Transaction amount
Each node of the blockchain network will have to validate (or not) the transaction through a
cryptographic algorithm. Each transaction is timestamped and added to the blockchain upon validation.
Each node must have a copy of the blockchain. You are free to use any suitable storage engine (database,
files, ...) as long as the blockchain is always available and decentralized.
2.1. Software development
The software is divided in 3 main parts:
The blockchain engine which validates and stores each and every transaction
The wallet app that allows users to send/receive transaction and store money.
The web application that let users explore the blockchain
2.1.1. Blockchain
You are free to use any language and libraries and existing solutions. The solution you implement/select
has to meet the following criteria:
2.1.1.1. Tokens
To avoid direct conversion between currencies, you need a token/money that will be used in all
transaction. You are free to choose the price/value of the token.
2.1.1.2. Peer-to-peer network
The peer-to-peer blockchain network prevents any participant or group of participants from controlling
the underlying infrastructure or undermining the entire system. Participants in the network are all equal,
and adhere to the same protocols.
A participant or group of participants is a node. Whenever a new transaction occurs, all nodes in the
network that want to maintain the latest version of the blockchain must update their copy of the
blockchain by adding the new transaction.-

2.1.1.3. Blockchain security
The solution must prevent fraud and falsification. The blockchain must be immutable (no deletion/
modification after a transaction has been validated).
2.1.1.4. Consensus mechanism
The consensus mechanism is the most important and vital aspect of the blockchain design. It is the
foundation of trust between users that data stored on the blockchain cannot be tampered with. As such,
it must have the following features:
High performance (low latency, large number of transactions per second)
Low power consumption
Irrevocability of transactions
2.1.1.5. Privacy
The blockchain must be "private by design" to respect users privacy. You have to implement a
"pseudonymization" solution to ensure that all data is kept in a form that does not allow direct
identification of a user.
2.1.1.6. Useful resources
Here is a non-limitative list of resources you can use to design/select your system:

2.1.2. Wallet
The wallet application enable users to interact with the blockchain engine. It will let users:
Create accounts
Send/receive transactions
See how many tokens they currently have
You are free to use any language/libraries/platform you want for the app. For the POC, it can be a
command line tool or a full-fledged desktop/mobile application.-

2.1.3. Web application
The web application allows users to graphically explore the content of the blockchain.
A typical use case for a blockchain explorer is to check the balance of a given address/pubkey or to verify
that a given transaction is included in the blockchain.
2.1.3.1. User accounts
Users will need an account to use the web application features. If they already have a Facebook or
Google account, they can automatically link it to their SupBank account. If they do not, they can create
an account with their email address.
2.1.3.2. Web interface
The home page show the last blocks of transactions and the last transactions that have been validated
by the different nodes.
Users can click on transactions to get details (sender/recipient/amount).
Users can also use a search bar to filter transactions by:
Wallet address (public key)
Nodes
Block identifier
A status page show a live map of the network, including all known nodes.
2.2. Supporting architecure
Your POC must include a demo network with several nodes. The network must be able to perform all
required tasks to ensure proper blockchain operation.-

3. Deliverables
Students should include the following elements in their final delivery:
A zip archive with the project source code. The source code must also come with the build system
used (Project file, autotools, libraries, ...), if any.
Project documentation.
Technical documentation explaining your choices and/or implementation choices/details on
the following items (at least):
Selected blockchain solution
Network map
User manual
The first document is an academic document. Address the reader as a teacher, not a client. This
document can be in French or in English, at your option. On the other hand, user manual must be
understandable by the client.-
