Blockchain vs Traditional Databases

Developers should learn blockchain to build decentralized applications (dApps) for financial markets, such as trading platforms, payment systems, and supply chain tracking, where transparency and security are critical meets developers should learn and use traditional databases when building applications that require strong data consistency, complex joins, and transactional integrity, such as banking systems, inventory management, or customer relationship management (crm) tools. Here's our take.

Pros

• They are ideal for scenarios with structured data and predefined schemas, where data relationships are critical and performance for read-heavy operations is a priority
• Related to: sql, database-design

Cons

• Specific tradeoffs depend on your use case
