Learning outcomes

You will (1) structure the dissertation; (2) write limitations honestly; (3) connect findings to practice.

7.1 Structure

Tariq structures the dissertation as introduction, systematic review, design, results, discussion and conclusion, with appendices for the codebook, search strings, flow diagram and scripts. Each results section begins with the question it answers and ends with a one-sentence summary. Dr Larsen asks him to keep the discussion separate from results so readers can see what was observed before what he thinks it means. A clear structure lets examiners follow the argument without hunting for evidence. Appendices are cross-referenced from the text.

7.2 Limitations

Tariq writes limitations in specific terms: forty protocols and nine incidents give imprecise estimates; incidents may be underreported; control type is coded from documentation that may not match practice; care is measured only through audit count; and the timelock analysis uses fourteen changes from one monitoring firm. For each, he states the likely direction of bias where possible. Specific limitations are useful to future researchers, while vague ones only signal that something might be wrong. He also explains how each limitation could be addressed.

7.3 Practice implications

For practitioners, Tariq translates findings carefully: protocols with privileged functions should document who controls them, use multi-signature for fund-affecting powers, and use timelocks long enough for monitoring and user response, with his pilot suggesting that 48 hours may be too short over weekends. He links these to EthTrust and ConsenSys guidance, noting that his data are consistent with that guidance rather than independently proving it. He adds that teams should publish their privileged-control arrangements so users and monitors can judge the risk, and that timelock periods should be chosen with monitoring coverage in mind.

7.4 Writing process

Tariq writes in short daily sessions, sharing chapters with Dr Larsen as they are drafted. Her comments focus on claims that outrun evidence and on figures that need clearer labels. He keeps a change log of major revisions. Two weeks before submission he reruns every script from a clean copy to confirm that every number in the text matches the outputs. Careful process prevents late surprises such as a mismatched table discovered by an examiner. Dr Larsen signs off the final draft.

Worked example

The dissertation separates results from discussion, lists five specific limitations with bias directions, and links practice advice to EthTrust and ConsenSys guidance.

Synthetic case. Writing, comments and results are synthetic; EEA EthTrust and ConsenSys best practices are real sources.

Errors and limits

Writing vague limitations hides the specific weaknesses future researchers need to know.

Exercises

• EX039 — Results and discussion. Why keep results and discussion separate? Rubric: 3 = readers see observations before interpretation;; 2 = clarity;; 1 = length;; 0 = none.
• EX040 — Limitation example. Name one stated limitation. Rubric: 3 = nine incidents give imprecise estimates;; 2 = underreporting;; 1 = vague;; 0 = none.
• EX041 — Bias direction. What does Tariq state for each limitation? Rubric: 3 = likely direction of bias;; 2 = direction;; 1 = cost;; 0 = none.
• EX042 — Weekend implication. What did the pilot suggest about 48 hours? Rubric: 3 = may be too short over weekends;; 2 = weekends;; 1 = too long;; 0 = none.
• EX043 — Guidance relation. How do findings relate to guidance? Rubric: 3 = consistent with but not independently proving it;; 2 = consistent;; 1 = contradict;; 0 = none.
• EX044 — Final rerun. What was done two weeks before submission? Rubric: 3 = reran all scripts from a clean copy;; 2 = rerun;; 1 = vague;; 0 = none.

Synthesis

Clear structure, specific limitations and carefully bounded practice advice make a dissertation credible and useful.
