Blockchain is a tool for shared state under contested trust. It is not a default architecture for every database problem.
The highest-ROI use cases we see: multi-party settlement, provenance across supply chains, and audit trails that cannot be quietly rewritten.
Success looks boring: clear contracts, identity, integration with existing systems, and operators who understand failure modes.
If a single party owns the data and the rules, you probably need a well-built API—not a ledger.
