SQL Server/Azure SQL Ledger in 300 Seconds

How do you prove that your data hasn't been tampered with—even by someone with sysadmin privileges? Traditional auditing tells you who changed something, but it doesn't prove the current state of the data is valid.

In this high-speed session, we tackle the ultimate trust challenge using SQL Server Ledger. We’ll skip the slides and go straight to the code, executing a update on a ledger-enabled table and immediately exposing it.

You’ll see how SQL Server uses cryptographic hashing to create a tamper-evident trail that is mathematically verifiable. By the end of this 5-minute blast, you’ll understand how to implement "zero-trust" at the data layer, giving your auditors the cryptographic proof they crave without the overhead of a decentralized ledger.

Cryptographic Proof over Audit Logs: Understand why Ledger is superior to standard triggers or Audit logs when proving data integrity to external regulators. Instant Forensics: Learn how to query sys.ledger_table_history to instantly view the full lineage of every row, including "hidden" changes. Blockchain Power, SQL Simplicity: Discover how to enable "tamper-evident" tables in your existing Azure SQL or SQL Server databases with minimal code changes.
