Azure confidential ledger

Azure confidential ledger is a database service that protects data using blockchain decentralized ledger features. It provides a tamperproof, unstructured data store backed by cryptographically verifiable evidence. This tool is primarily used for scenarios requiring high integrity and auditability of stored records, ensuring that once data is written, it cannot be altered or deleted without detection.

You should choose this service when you need an immutable record of transactions or events that must remain unchangeable over time. Be aware that there is no free tier available for this service. Instead, it operates on a pay-as-you-go pricing model, meaning costs will accumulate based on actual usage without any initial free allowance to test the platform.
