When Google launched the Knowledge Graph in 2012 (yes, it really has been 10 years – we had to double check as well) everybody got to experience the power of connected data points. Today, many projects use that very concept to link data together in order to gain better insights, as well as... read more
Surely the most exciting part of Web3 is that it brings us closer to Web4j, which will be entirely based on property graphs. Past decentralization, a great thing about graphs is that they have no center, or equally that every connected member is a center (has centrality). You are a center. The... read more
