The Blockchain-based database is a combination of traditional database and distributed database where data is transacted and recorded via Database Interface[1] (also known as Compute Interface)[2] supported by multiple-layers of blockchains.[3] The database itself is shared in the form of an encrypted/immutable ledger which makes the information open for everyone.[4]

Concept

In actual case, the blockchain essentially has no querying abilities when compared to traditional database and with a doubling of nodes, network traffic quadruples with no improvement in throughput, latency, or capacity.[5] To overcome these shortcomings, taking a traditional database and adding blockchain features to it sounds more feasible.[6] That's how the concept of Blockchain-based database came into existence which consists of multiple member clouds riding on two primary layers, the first one is Database Interface and the second one is the Blockchain Anchoring.[1]

List of Blockchain-based databases

This list consists of the databases which are developed and deployed through a traditional database model over a blockchain framework;[5]
