Blockchain is a decentralized digital ledger that records transactions across multiple computers, while traditional databases are centralized systems that store data in structured formats.
Advantages of blockchain include enhanced security, transparency and traceability, reduced intermediaries, and global accessibility. Limitations include scalability challenges, complex implementation, and regulatory uncertainty.
Advantages of traditional databases include high customizability, mature ecosystem, performance optimization, and flexibility in data management. Limitations include security vulnerabilities, limited transparency, and single point of failure.
When to use blockchain: high security and immutability, transparency among stakeholders, reduction of intermediaries, and multiple parties needing shared access to data. When to use traditional databases: high performance, customizability and flexibility, no need for decentralization or immutability, and availability of established tools and technologies.
