It does this by using blockchain cryptography to store the full history of all data modifications in protected tables, so that changes can be audited and any unauthorized modifications can be quickly identified. Now, I know that blockchain cryptography is kind of a buzzword phrase these days, so let's break this down to see exactly how this technology is used in SQL Server to enhance your databases security.
