CBCP Blockchain Use Cases and Industry Applications

Question 1

Which blockchain property most directly helps supply chain provenance tracking?

Accepted Answer

An immutable, shared audit trail of custody events

Answer

A tamper-evident ledger shared among participants lets each handoff be recorded and verified. This allows end-to-end traceability of goods.

Question 2

In healthcare, why is blockchain often proposed for patient record exchange?

Accepted Answer

It can provide auditable, permissioned access and integrity proofs while keeping sensitive data off-chain

Answer

Typical designs store hashes and access permissions on-chain and keep sensitive records in off-chain storage. This gives integrity and an audit trail while helping with privacy compliance.

Question 3

Which concept describes a user-controlled digital identity not dependent on a single central authority?

Accepted Answer

Self-sovereign identity (SSI)

Answer

Self-sovereign identity lets individuals hold and present verifiable credentials, often anchored by decentralized identifiers (DIDs) on a ledger, without relying on one central provider.

Question 4

Which scenario is generally the BEST fit for a blockchain solution?

Accepted Answer

Multiple mutually distrusting parties needing a shared, tamper-evident record without a trusted intermediary

Answer

Blockchain adds the most value when several parties share data, trust is limited, and no neutral intermediary exists. For single-writer or fully trusted settings, a conventional database is simpler and cheaper.

Question 5

How can blockchain improve cross-border payments?

Accepted Answer

By reducing intermediaries and settlement time through a shared ledger

Answer

A shared ledger can cut the chain of correspondent banks and enable faster, more transparent settlement. Compliance obligations such as KYC/AML still apply.
