Are there any specific use cases you could share with us of companies using blockchain and web3 technology?
Insurers handle a wide range of events related to policyholders, each with a specific structure. Take, for instance, a scenario involving car insurance, where a policyholder files a damage claim. In this case, the damage claim event has a particular structure and details.
The primary objective for insurance companies is to establish and maintain the authenticity of these events. They want to ensure that if a policyholder requests proof that the insurance company has not tampered with the event details over time, they can provide such evidence. Additionally, insurance companies may need to share this proof with other insurers for collaborative purposes or when customers switch providers.
Here’s where blockchain technology and web3 come into play. Blockchain serves as a digital notary in this context. The insurance company can record the details of each event, such as the car damage claim, on the blockchain. By doing so, they create an immutable and time-stamped record of the event’s structure and information.
When a policyholder or another insurance company needs proof of the event’s authenticity or structure, they can reference the blockchain. The blockchain ledger acts as an irrefutable source of truth, verifying that the event has not been altered or tampered with since its initial recording. This use of blockchain and web3 technology enhances transparency, trust, and security within the insurance industry, benefiting both insurers and policyholders alike.
