Blockchain and Smart Contracts in Claims Settlement

Abstract

In this paper, a model is presented in the operational form of blockchain and smart contract utilization to modernise insurance claims settlement, which is enterprise-ready. Design a permissioned, Ethereum-compatible ledger that encodes policy terms limits, deductibles, exclusions and orchestrates deterministic claim state transitions from First Notice of Loss (FNOL) to payout. Off-chain storage stores sensitive artifacts (PII/PHI, images, medical records) encrypted in vaults, and on-chain records append cryptographic digests and events that can be audited by tampering evidence. This is provided by evidence (in the form of signed oracles, such as weather indices, hospital discharge summaries, police reports), and permits parametric claims to be settled quickly and routine indemnity claims to undergo high straight-through processing (STP) with human attention reserved to exceptions. The methodology emphasizes formal assurance (static analysis, property-based tests, optional formal verification), runtime safety (circuit breakers, timelocked upgrades), and robust key/oracle governance. Pilot testing in pilot testing, the methodology provides a shorter cycle time, less reconciliation, and quantifiable mitigation of fraud-leakage but still ensures regulatory compliance by selective disclosure and privacy-by-design. Also work through the dynamics of constraints throughput and fee dynamics, legal enforceability, legacy interoperability, and privacy-versus-transparency trade-off and a roadmap of staged adoption, starting with low-dispute, oracle-rich products, then triage, partial advances, and subrogation workflows. Findings indicate that blockchain is likely to be the most useful as a coordination/assurance layer to supplement, but not to substitute, fundamental insurance infrastructure
