Blockchain Use Cases and Business Process Re-engineering
What this domain tests
This domain tests whether you can select and redesign processes where a shared ledger adds value: trade finance, supply chain, KYC, settlement, healthcare consent, and public-sector registries.
Core rules
- A credible use case has multiple parties, a trust or reconciliation problem, shared data, an audit requirement, and no trusted central operator - or a willingness to replace one.
- Re-engineering starts with the process, not the platform. Map handoffs, duplicate ledgers, manual checks, and dispute points.
- Decide what belongs on-chain: proofs, hashes, ownership, and status. Keep bulky documents and personal data off-chain.
- Tokenization changes settlement and liquidity but raises legal classification and custody issues.
- Benefits must be measured: cycle time, dispute cost, capital release, audit effort. Otherwise you have a database with extra steps.
Worked example
A letter of credit involves importer, exporter, banks, insurer, and shipper. Today each keeps its own record and reconciles documents. On a shared ledger, document hashes and status events are written once; permissions reveal only relevant fields. The bank's release becomes a chaincode condition. The reasoning: value comes from removing duplicate verification, not from storing PDFs on-chain.
Traps
Do not propose blockchain for a single-organization workflow. Do not assume on-chain data is true - garbage in, garbage out. Do not ignore off-chain document custody. Do not skip change management or legal recognition of digital documents.
