Abstract :
Blockchains are here for more than tenfifteen years and currently, we are adopting the
blockchain techniques in databases, and vice-versa.
Example, A typical blockchain data structures, such as
cryptographically-linked blocks and Merkle trees, have
been interspersed. Into verifiable databases. On the
other hand, database techniques, such as sharding and
concurrency control, have been interspersed. Into
blockchains. In this paper, I am looking at systems that
combine both blockchain and database techniques. I
classify these systems into three types and that is given
below (1) Permissioned Blockchains, (2) Hybrid
Blockchain Database Systems, (3) Ledger Databases. I
also present their anatomy, including the features,
techniques, and design choices, by analyzing a few
representative systems. In the end, I highlight their
challenges and discuss research directions
