Blockchain Tables

The tech world has been waiting for the introduction of blockchain to the enterprise level eagerly. Why? Because blockchain technology has the ability to ensure trustworthy databases.

Oracle database 21c solves this problem with blockchain tables.

The rows in 21c’s blockchain tables are cryptographically hashed during data entry, making them unalterable in the future.

According to oracle, “this essentially creates an insert only table, and users are unable to update or delete Blockchain Table rows. In addition, users are also prevented from truncating data, dropping partitions or dropping Blockchain Tables within certain time limits.”

Simply put, this leverages the core functionality of blockchain technology and provides trustworthy record-keeping.
