Decentralized graph database

The general disadvantages of graph databases are:

Graph databases are purpose-built to store and navigate relationships . Relationships are first-class citizens in graph databases, and most of the value of graph databases is derived from these relationships. Graph databases use nodes to store data entities, and edges to store relationships between entities.

Graph databases are not as useful for operational use cases because they are not efficient at processing high volumes of transactions and they are not good at handling queries that span the entire database .
