A distributed ledger solves a specific problem: several parties need to share one trustworthy record, and none of them should control it. If that is not your problem, a ledger adds cost and complexity without adding value.
The four questions
Four questions settle most cases. Do multiple organisations write to this record? Is there a genuine trust gap between them? Does provable history have commercial value? And does the data need to stay unchanged once written?
- Multiple writers. If only your organisation ever adds to the record, a database you control is simpler.
- A real trust gap. If the parties already trust one operator, that operator can run the system.
- Value in provable history. If nobody will pay or decide differently because the history is provable, the guarantee is wasted.
- Data that must not change. If records are regularly corrected or deleted, for example for privacy reasons, a ledger makes that harder.
If the answers are mostly no, a well-designed shared database will be cheaper, faster and easier to govern. Saying so early protects budgets and credibility, and it is why clients trust our recommendation when the answer is yes.
When the answer is yes
Ledgers earn their place where several organisations must agree on who owns what, and where disputes or reconciliation are expensive today. Trade documents passed between shippers, banks and customs; certificates that must be verified by strangers; assets that change hands between many parties. In these cases a shared record removes rounds of checking, and smart contracts can settle obligations automatically.
The most useful sentence in a feasibility study is sometimes: you do not need a blockchain.
What a good feasibility study delivers
A clear answer, the evidence behind it and a costed path either way. If a ledger is right, the study names the type of network, who runs the nodes, how keys are held and what must be audited before launch. If it is not, it describes the simpler system that solves the same problem, so the work is not wasted.
