Zenon was launched as a POS/MS hybrid cryptocurrency in Mar 2019 and proposes a sharding-based decentralized architecture called the Network of Momentum (NoM), which aims to build upon existing blockchain and DAG architectures.
Due to sharding, the network will reportedly be able to scale linearly as the number of nodes grows. The protocol differs from traditional blockchain consensus as transactions are not treated in batches, but asynchronously processed within shards, with the overall state of the network verified and validated at the end of each epoch (each epoch having a random timeframe). The network will also feature a Turing complete scripting language that will allow developers to build and run zApps, create digital assets, and allow low-resource devices to participate in the network.
