from the article you are replying to >This is because existing systems were designed to function—and to achieve consensus—in public scenarios amongst anonymous, untrusted actors with maximum transparency. Because of this, transactions are posted “in the clear” for all to see, every node in the network executes every transaction, and computationally intensive consensus algorithms must be employed. These safeguards, while necessary to ensure the integrity of public blockchain networks, require tradeoffs in terms of key enterprise requirements such as scalability and confidentiality. .. >Coco achieves this by designing specifically for confidential consortiums, where nodes and actors are explicitly declared and controlled. Based on these requirements, Coco presents an alternative approach to ledger construction, giving enterprises the scalability, distributed governance and enhanced confidentiality they need without sacrificing the inherent security and immutability they expect.
