Ink consortium blockchain has designed and implemented an account system that can cater to a large number of anonymous users (from public blockchain users, or from consumers who are covered by the Sovereign Consortium Blockchain) to manage digital assets and interact directly with the consortium blockchain. This account system is called Ink Account.The vision of Ink is to provide Sovereign Consortium Blockchains to different use cases, to build a blockchain based infrastructure for the Creative Industry where various applications were possible and correlate to each other in one system. Based on public blockchain (Qtum), an Intellectual Property Assets Exchange is built as a trusted corridor for cash generation and token issuance, making it an integrated ecosystem. At the same time, the cross-chain protocol enables value and information to flow freely between public blockchain and consortium blockchains.
