Question 1

What is blockchain for supply chain management?

Accepted Answer

Blockchain for supply chain management uses a shared, distributed ledger to record and verify transactions, product movements, documents, and events across a supply network. It can improve traceability, transparency, security, and coordination between manufacturers, suppliers, logistics providers, retailers, regulators, and customers.

Question 2

How does blockchain improve supply chain traceability?

Accepted Answer

Blockchain records supply chain events in a tamper-resistant sequence, creating a verifiable history of a product’s origin and movement. When combined with QR codes, RFID tags, IoT sensors, or digital identities, it can help organizations track products, verify provenance, identify problems, and support faster recalls.

Question 3

What are the main benefits of blockchain in supply chains?

Accepted Answer

Key benefits include improved visibility, stronger data integrity, reduced fraud, faster document processing, automated payments, better compliance reporting, and more efficient collaboration. Blockchain can also help reduce disputes by giving authorized participants access to a shared record of agreed transactions and delivery events.

Question 4

What challenges can enterprises face when implementing supply chain blockchain?

Accepted Answer

Common challenges include integration with legacy systems, inconsistent data quality, limited partner participation, privacy concerns, unclear governance, regulatory uncertainty, scalability requirements, and implementation costs. Blockchain does not automatically guarantee accurate information, so enterprises need strong validation processes and reliable data sources.

Question 5

Is blockchain suitable for every supply chain?

Accepted Answer

Blockchain is most valuable when multiple independent organizations need to share trusted records but do not rely on a single central database. Businesses should evaluate the use case, data requirements, governance model, partner readiness, and expected return on investment before deployment. In some situations, a conventional database may be simpler and more cost-effective.
