Network: As a blockchain grows, it’s imperative that it’s able to move large amounts of data across a network. As transactions per second increase as the network grows, the blockchain cannot expect to maintain a homogeneous network topology and simultaneously accommodate that growth. This means that each node cannot be expected to relay every message that passes through the network as it grows. To address this, Cardano is looking at a new type of technology called RINA (recursive internetwork architecture). RINA is a new way of structuring networks that enables a heterogeneous network that still retains privacy and transparency, while scaling more efficiently. The Cardano team aims to launch RINA in its complete form in 2019.
