Distributed Database
Record-keeping system shared among multiple computers without central authority.
Beginner-friendly explanation
A distributed database is a collection of information stored across multiple connected computers. Each keeps a copy to secure the data.
📌 Example:
Blockchain is a distributed database where all validators have the same version of the transaction history.
Intermediate-level insight
In a distributed database, consistency is maintained through protocols (e.g., consensus) to synchronize all copies. This ensures resilience to failures and attacks.
📌 Example:
In Bitcoin, even if one server goes down, other nodes continue to operate with correct data.
Advanced perspective
Advanced distributed databases integrate Byzantine fault tolerance (BFT) algorithms, data partitioning mechanisms (sharding), and optimize the consistency, availability, and partition tolerance trade-off (CAP theorem).
📌 Example:
The Solana network uses an optimized consensus to tolerate certain failures while maintaining high processing speed.
