 Because Confidential Ledgers use self-signed certificates securely generated and stored in an enclave, the signing certificate for each Confidential Ledger must first be retrieved from the Confidential Ledger Identity Service.

 Data that needs to be stored immutably in a tamper-proof manner can be saved to Azure Confidential Ledger by appending an entry to the ledger.

 Since Confidential Ledger is a distributed system, rare transient failures may cause writes to be lost. For entries that must be preserved, it is advisable to verify that the write became durable. Waits are blocking calls.
