Does the problem need a blockchain?
A shared database with good access control solves many problems at lower cost. A ledger earns its place when several parties who do not fully trust one another must write to the same record, and when no single party should be able to alter history. Supply chain provenance, trade finance and inter-company settlement fit that description. Typical cases that pass include multi-party provenance, shared settlement records, regulated data exchange and certificate registries; those that fail often involve one dominant owner.
We run a short assessment before design. Who writes, who reads, who is trusted, what happens when parties disagree and what data must stay private? If the answers point to a single operator, we say so and suggest a conventional architecture. That honesty saves months and keeps the credibility of projects that do proceed. Prototype quickly, but measure what matters: participants joined, transactions processed, disputes resolved and time saved. Decide on scale-up using those numbers, not enthusiasm.
