Zero-Knowledge Proof: Verifying Blockchain Transactions with Less Risk

One of the most important traits of blockchain is transparency. However, some businesses that deal with sensitive information, such as those in finance, require a certain level of privacy and security. This paper explains how zero-knowledge proof / protocols can enable blockchains to continue verifying transactions while maintaining a degree of confidentiality.

Blockchain for Insurance: From Preventing Fraud to Automating Claims

Insurance is exposed to a variety of fraudulent schemes: from sharing an insurance plan after divorce to withholding critical information that may influence risk assessment. In this regard, blockchain can address some of the pain points found in the insurance industry. This study explains how the technology helps to improve security, mitigate fraud, automate record sharing between organizations, and cut operational costs. Finally, the paper covers some technical aspects of implementation and highlights scenarios where blockchain fits best.
