Does Your Business Need a Blockchain or a Shared Database?

Imagine three companies tracking a shipment. If all three already trust one operator to edit the record and settle disputes, a conventional shared database may be the easiest system to run. Blockchain becomes worth examining when independent participants need to verify a common history under agreed rules.

Identify the trust problem

Name who can submit a record, who verifies it, and what stops one participant from rewriting the record in their own interest. Record what information starts outside the system. A ledger can preserve a submitted temperature reading; it cannot independently prove that the sensor was attached to the right shipment.

Design for mistakes and disclosure

Explain how an incorrect entry is corrected, who can see it, and what happens when an operator loses access. Avoid putting customer details on a public ledger merely because the system accepts them. If a smart contract is involved, document upgrade rights and which actions are irreversible. Ethereum’s introduction to smart contracts.

Compare a minimal pilot with the simpler option

Run the same transaction through a database prototype and a ledger prototype. Compare cost, confirmation time, recovery, integration work, and the ability to audit a dispute. If the blockchain version does not solve a concrete governance problem, record that finding before funding production development.
