Top 7 blockchain-based databases

Blockchain technology, initially developed as the backbone for cryptocurrencies, has evolved to have far-reaching applications beyond virtual currency, including the trade of digital assets like NFTs and usage across various industries. The text explores the concept of blockchain-based databases as a decentralized, secure, and immutable alternative to traditional centralized databases, highlighting key differences such as the decentralized network structure and consensus-based record validation process. It examines the strengths and weaknesses of blockchain databases, including cost implications, fault tolerance, performance, and security considerations, suggesting blockchain for scenarios requiring high security and fault tolerance, while traditional databases are better suited for high-speed performance needs. The text further introduces seven notable blockchain-based databases, such as BigchainDB, Apache Cassandra, and ProvenDB, detailing their unique features and the advantages they offer, like immutability and decentralized data storage.
