Each block of data is cryptographically linked to the one before it, creating an immutable chain that every participant can verify independently — eliminating the need for a single trusted intermediary to certify that a record is accurate.<br /> <br /> ⚙️ In insurance, blockchain pilots and production applications have emerged across several use cases. [[Definition:Parametric insurance | Parametric insurance]] products, for example, can use smart contracts — self-executing code stored on a blockchain — to trigger automatic [[Definition:Insurance claim | claim]] payments the moment a predefined event (such as an earthquake exceeding a set magnitude) is confirmed by an [[Definition:Oracle | oracle]] data feed. Other applications include [[Definition:Reinsurance | reinsurance]] settlement, where shared ledgers reduce reconciliation delays between [[Definition:Cedent | cedents]] and reinsurers, and [[Definition:Proof of insurance | proof-of-insurance]] verification, where a blockchain record lets third parties confirm [[Definition:Insurance coverage | coverage]] in real time without contacting the [[Definition:Insurance carrier | carrier]] directly.<br /> <br /> 🌐 Despite considerable hype, widespread adoption in insurance remains selective. The technology&#039;s genuine strengths — transparency, auditability, and automation through smart contracts — deliver the most value in multi-party workflows plagued by duplicated data entry and slow reconciliation. As [[Definition:Insurtech | insurtech]] firms continue to refine interoperability standards and regulators grow more comfortable with digital-native record-keeping, blockchain is likely to move from isolated proofs of concept into the operational backbone of specific insurance processes rather than becoming a universal replacement for existing infrastructure.<br /> <br /> &#039;&#039;&#039;Related concepts&#039;&#039;&#039;<br /> {{Div col|colwidth=20em}}<br /> * [[Definition:Smart contract]]<br /> * [[Definition:Parametric insurance]]<br /> * [[Definition:Distributed ledger technology (DLT)]]<br /> * [[Definition:Insurtech]]<br /> * [[Definition:Straight-through processing (STP)]]<br /> * [[Definition:Digital distribution]]<br /> {{Div col end}}</div>
