Why do they use Qtum Blockchain?
INKs strategy is Glocalization", a combination of "Globalization" and "Localization". Under this framework, INK will customize, deploy and operate multiple INK consortium blockchains in different cultural context across the globe. Each INK consortium blockchain will become a distributed infrastructure for the local creative industry, focusing on the realization of synergies with the highly-efficient localized business networks. Such synergies will then be globalized using INKs cross-chain protocol which provides interoperability between a public chain (Qtum or Ethereum), and INK consortium-chains. This will streamline the transfer of value and information across different chains and create an efficient globalized network.
