Explain private key security in the context of the scenario
For private key security, evidence should be selected before writing the conclusion. Record the observation, identify the relevant context, then explain what the observation can and cannot prove. This avoids overclaiming and gives the blockchain security report a more defensible academic tone.
Where possible, compare the expected state with the observed state. For blockchain security, that comparison gives the reader a clear basis for judging whether the control, configuration, artefact or result is acceptable.
Evaluate 51% attacks instead of listing it
Students often lose marks by describing 51% attacks without evaluating it. A better approach is to compare the expected behaviour with the observed behaviour, identify the security consequence, and justify the next control or investigative step. That sequence keeps the discussion specific to blockchain security.
A useful discussion also acknowledges constraints. Time, available evidence, lab scope, legal boundaries and incomplete data can all limit what can be concluded about immutability or oracle trust.
