A secured and distributed database architecture, the blockchain, has been introduced and launched for ten years. A great number of cryptocurrency and its ecosystem, competing to become the de-facto blockchain, has also been enriched over time. However, they are still merry-go-round on the old-traditional path of development which, in fact, makes this industry, as a whole, evolve into a series of stand-alone and disconnected pieces. Apparently, that's a major problem and we call it a "lack of interoperability" in the blockchain ecosystems today.
