World state reflects all committed transaction on the blockchain.
This is basically a key-value store which is updated as a result of transactions and chaincode execution.

LevelDB is a key-value store whereas CouchDB stores data as JSON objects which allows rich queries to run against the database.
Why This Matters for Blockchain Technology
Understanding World state database is not just an academic exercise — it has real-world implications for how blockchain systems are designed, deployed, and secured. Whether you are a developer building decentralized applications, a business leader evaluating blockchain adoption, or a curious learner exploring the technology, this knowledge provides a critical foundation.
