Learning outcomes

You will (1) assemble a professional portfolio; (2) review outcomes against goals; (3) plan continuing development.

12.1 Assembling the portfolio

Marcus assembles a portfolio of his work: the authorisation, the custody review report, the donation reconciliation script and results, the documented workflow, the controls register with verification evidence, the case analysis, the quality measures and his reflections. Each item has a short note explaining what it shows. He removes donor personal data and replaces sensitive addresses with placeholders. A portfolio demonstrates competence through real work rather than claims, and it gives future employers and colleagues evidence of how he approaches problems.

12.2 Reviewing outcomes

Marcus reviews his goals from the start of the programme: understand the charity's cryptoasset donations, find and fix the main custody weaknesses, make conversions safer and keep donors' trust. Evidence shows all three original findings closed, discrepancies reduced from six to two a month, a documented workflow in use and trustees satisfied with reporting. He also notes gaps: he did not review the exchange's controls, and the charity still relies on a single exchange. He recommends assessing a second exchange during the next year as a contingency.

12.3 Continuing development

Marcus plans his development: a course on payment fraud prevention, reading the EEA EthTrust specification to understand contract assurance better, and joining a practitioner community for charities handling digital assets. Ms Holm's final assessment praises his evidence-based approach, proportionate judgement and clear reporting. She notes that he stayed within his scope and asked for help when needed. Marcus reflects that the programme taught him that cryptoasset security relies on the same disciplines as any financial control: clear roles, verification and honest records.

Worked example

Marcus's portfolio evidences three closed findings and discrepancies down from six to two monthly, and he recommends assessing a second exchange.

Synthetic case. The portfolio, review and plans are synthetic; EEA EthTrust is a real source.

Errors and limits

Including donor personal data in a portfolio breaches the privacy it should demonstrate.

Exercises

EX056 — Portfolio sanitising. How is the portfolio sanitised? Rubric: 3 = donor data removed, sensitive addresses replaced by placeholders;; 2 = redaction;; 1 = vague;; 0 = none.
EX057 — Original goals. Name one of Marcus's original goals. Rubric: 3 = make conversions safer;; 2 = fix custody weaknesses;; 1 = learn to trade;; 0 = none.
EX058 — Remaining dependency. What dependency remains? Rubric: 3 = reliance on a single exchange;; 2 = one exchange;; 1 = vague;; 0 = none.
EX059 — Development step. Name one development step planned. Rubric: 3 = reading the EthTrust specification;; 2 = fraud prevention course;; 1 = vague;; 0 = none.
EX060 — Final reflection. What did Marcus conclude about cryptoasset security? Rubric: 3 = it relies on the same disciplines as financial control;; 2 = same disciplines;; 1 = entirely new;; 0 = none.

Synthesis

A sanitised portfolio, honest review and development plan complete professional practice.
