Multi-model architectures enable the querying of data from different sources through a unified interface, providing interoperability among databases. However, support for blockchain is still scarce. Inter-MOON is a new middleware approach that promotes the interoperability of relational databases and blockchain through virtualizing blockchain assets in a relational environment, allowing for the execution of SQL DML commands. Experimental results show that compared to the blockchain, Inter-MOON provides minimal overhead in writing operations or reading operations that retrieve many entries but significant overhead when querying a few entries, trading high performance for powerful querying capabilities.
