Project Description:The most important component of the course is a quarter-long creative project on topics broadly related to distributed transactions, consensus protocols, and distributed ledgers (blockchain fabrics). The project must be done in groups* (up to five students), and the role and contributions of each group member must be clearly articulated. All projects must be approved and supervised by the instructor. The outcome of the final project will consist of the following. (1) Designing novel consensus protocols; benchmarking and studying existing consensus protocols; developing novel techniques or architectures to improve the performance of a blockchain fabric (e.g., sharding, cross-chain, hybrid protocols [ResilientDB Fabric, Codebase, Hands-on Tutorial, Blog, Wiki]); or developing novel applications for blockchain (e.g., DeFi applications with [Radix DeFi Engine, Overview of Scrypto Smart Contracts, and Scrypto Documentation]) (2) Writing a grant proposal for startup seed funding or a short research paper with the ultimate goal of submitting to a top-tier conference, of course, submission is optional and does not affect your final grade. All project related-reports must be written in LaTex using ACM templates or in a form a detailed and accessible blog or professional website (e.g., Blog, CryptoLunch, Resilient Record).
Grant Proposal TrackWhether you choose the grant proposal or research paper route, there needs to be a proof-of-concept prototype of your ideas in order to demonstrate feasibility or effectiveness. For the grant proposal track, we will adopt the well-known Small Business Innovation Research (SBIR) program that fosters commercialization of research ideas by small businesses. SBIR project description template can be found here.
Research TrackFor the research track, we adopt standard conference-style paper such as (PVLDB or SIGMOD). An example of a well-written blockchain research paper would be ResilientDB, and many more examples can be found in our ECS265 course.
Research PaperA research paper (and/or presentation slides) would consist of the following key components
- Motivation (why this problem is important and interesting)
- Gap (what are the challenges and what are the shortcomings of the most relevant work)
- Problem statement
- Key intuitions behind your proposed approach and sketch of the solution in a top-down approach
- Key benefits of your proposed approach
- Overall architecture/design of your solution
- Details of your solution
- Analytical correctness and complexity results
- Implementation Details
- Evaluation methodology and plans (competing algorithms, datasets, platforms, etc.)
- Empirical results (e.g., latency, throughput, precision, recall, f-measure, etc.)
- List of contributions and their importance (both scientific and technical contributions)
- Future Directions/Next Steps
Benchmarking PaperA benchmarking paper (and/or presentation slides) would consist of the following key components
- Motivation (why this problem is important and interesting)
- Gap (what are the challenges and what are the shortcomings of the most relevant benchmarking work)
- Problem statement
- A brief survey/discussion of relevant approaches/systems
- Justification for choosing these approaches/systems
- Evaluation Methodology:
machines/cluster requirements & setup, single-node and multi-nodes configurations in-memory vs. disk-based approaches, selected systems/engines, data workloads (synthetic data and/or real data), query workloads, types of experiments.
- List of your contributions and their importance (both scientific and technical contributions)
- Future Directions/Next Steps
Weekly Progress Meetings:
It is important that tangible progress is made every week. Progress must be captured in slides and can be any of the following categories. To make healthy progress, we need to satisfy one or more of the categories below each week. Of course, there could be an exception if you have several tests/exams, etc. in one week. But generally, it is important to have a consistent and healthy momentum. To make steady progress, at least one of the categories below must be fulfilled each week.
- Proposing a new well-thought idea (captured clearly on the slide),
- Solidifying an existing idea or algorithm (captured clearly on the slide),
- Providing correctness or time/space complexity proofs of the proposed algorithms/protocols,
- Formulating a set of new challenges with partial solutions (also captured clearly on the slides),
- Developing a module of the ongoing research prototype,
- Reporting detailed implementation progress,
- Evaluating and presenting a set of experimental results, and/or
- Completing the write-up for several sections of a research paper
Weekly Presentation:Each student is expected to present 1 (or 2 depending on the number of students taking the course) papers throughout the semester. All presentations are done in groups, so up to 4 students need to coordinate, study, and present the paper together. Students must also submit their presentation slides to be posted on the website. Students must coordinate with the TA in advance for the paper they wish to present (we will adopt the first-come, first-served when assigning papers). All paper selection must be sent to the TA before September 30, if no selection is received by the due date, a random assignment will be adopted by the TA. We will start the student presentation starting October 3, 2022. Each week, we will have two presentations, one on Monday and one on Wednesday. We dedicate the Friday of each week to have an even deeper discussion on the papers presented during the week. The two groups of presenters will lead the Friday discussion, so it is expected that all of them coordinate and prepare before the Friday meeting. Please note that the two papers selected for each week are highly related to ensure a coherent and exciting discussion.
Furthermore, everyone is expected to attend all lectures, namely, participating and attending when your peers (other students in the class) are presenting their papers. So half of the presentation grade will be reserved for giving a high-quality presentation and the other half would be dedicated to class participation, i.e., attending every lecture and asking insightful questions!
Additionally, every week, each student must choose one paper among the papers that are being presented that week and write a conference-style review. A standard template for writing a review consists of (1) explaining the paper in your own words in one or two paragraphs; (2) three strong points; (3) three weak points; (4) detailed concise comments that expand upon the weak points and beyond. When writing strong and weak points please avoid general comments such as weak motivations or poor writings and be as specific as possible. In your detailed comments, in the end, you could include such general comments.
* With prior permission from the instructor, the projects can be done individually if there is sufficient justification.
For each group, it is recommended that each member lead one aspect of the project while contributing and learning about other parts. It is further recommended a project manager is elected within a group to coordinate all efforts and manage the group dynamics in addition to making technical contributions to the project.
A fact of life, when there is group work, whether at school or in society, there are occasional conflicts; and it is crucial to learn how to resolve our differences and be receptive, open, and kind to one another. In kindness and reflection, we shall aim to resolve all conflicts. It is the group's responsibility to handle all internal affairs, and only when absolutely necessary involving the instructor. But note, only under very rare exceptional circumstances, a group re-structuring would be granted because once the group is formed, at least for 10 weeks, we must learn how to work with each other in harmony.
