This semester's Challenge Task (CT) is to implement either (a) a Decentralized Application (DApp) deployed on the Ethereum Blockchain (BC) or (b) a solution prototype that implements a convincing use-case that leverages the BC’s immutability in a different BC or Distributed Ledger (e.g., Bitcoin, Corda, or NEO). The selection and definition of the use-case depends on the group. The application domain can range from gambling systems, file transfer applications, supply-chain of products, or any decentralized system. The groups shall inform the teaching assistants on the topic and discuss the feasibility of the proposal. One can check past CTs (e.g., Challenge Task 2018, Challenge Task 2019, and Challenge Task 202) to have an idea about examples of applications.
Even though the groups are free to choose the CT focus, either (a) or (b), and the solution to be implemented, all groups must ensure that all requirements are met and follow the defined deadlines. The necessary information to fully accomplish the CT, assumptions, libraries, tools, and impact on the grade are detailed in the next sections and on the CT Formal Description (PDF, 168 KB).
Each CT group is free to decide on the design of the DApp or solution. For example, the architectural decision on how the communication with the BC or Smart Contracts (SC) will be performed. However, for each CT group, the following key requirements need to be met:
Further suggestions include:
The following facts may be assumed:
Note: Further assumptions, which are not restricting these assumptions above, can be made according to each group's approach.
The items below represent supporting libraries, tools, or references that are recommended to be taken into consideration.
During the challenge task each group will be able to ask questions and get support from their supervisors:
The groups that not discussed or sent their topics to the teaching assistants are encouraged to contact them as soon as possible.
