Learning outcomes
You will (1) analyse systemic and shared risk; (2) apply ethical reasoning to institutional choices; (3) balance duties to stakeholders.
4.1 Systemic and shared risk
A shared settlement ledger links three institutions, so a failure at one can affect all. Nadia analyses shared risks: a compromised validator at one partner, a contract defect affecting all balances, or a dispute about a settlement that the ledger records as final. She separates risks each institution controls from risks that only collective action can reduce. For collective risks she proposes shared controls, such as joint incident procedures and agreed criteria for pausing. Systemic thinking matters because members of all three credit unions could be harmed by one partner's weakness.
4.2 Ethical reasoning
Nadia considers ethical questions. Members' transfer data will be visible to all three institutions' validators; is that consistent with members' expectations of confidentiality? A pause would stop settlement for everyone; who has the right to impose that cost? She applies principles of harm avoidance, fairness and transparency. She recommends that only settlement amounts and pseudonymous institution references appear on the ledger, with member details kept in each credit union's own systems, and that pausing require two institutions and a published post-incident explanation to members.
4.3 Balancing duties
Nadia's duties pull in different directions: to her employer's commercial interest, to its members, to the partners and to regulators. She records where they conflict, for example between faster settlement and stricter controls that slow it. She recommends resolving conflicts openly through the risk committee, with dissent recorded. Professor Tanaka emphasises that ethical practice includes speaking up when a decision seems wrong and documenting that view. Nadia writes her concerns about the vendor-controlled upgrade key into the committee papers, ensuring the issue is considered rather than quietly accepted.
Worked example
Nadia separates individual from collective risks, keeps member details off-ledger and records her concern about the vendor upgrade key in committee papers.
Synthetic case. The risks and committee papers are synthetic.
Errors and limits
Treating shared-ledger risk as each institution's private matter ignores harm that spreads to all members.
Exercises
- EX016 — Shared risk example. Name one shared risk. Rubric: 3 = a contract defect affecting all balances;; 2 = compromised partner validator;; 1 = office fire at one branch;; 0 = none.
- EX017 — Collective control. What shared control does Nadia propose? Rubric: 3 = joint incident procedures;; 2 = agreed pause criteria;; 1 = vague;; 0 = none.
- EX018 — Ledger data choice. What appears on the ledger? Rubric: 3 = settlement amounts and pseudonymous institution references;; 2 = amounts only;; 1 = member names;; 0 = none.
- EX019 — Pause condition. What must accompany any pause? Rubric: 3 = two institutions and a published explanation;; 2 = two approvals;; 1 = vague;; 0 = none.
- EX020 — Speaking up. How does Nadia raise the upgrade-key concern? Rubric: 3 = writes it into committee papers;; 2 = documents it;; 1 = stays silent;; 0 = none.
Synthesis
Systemic analysis and ethical reasoning guide fair choices among institutions.
