Cosmos Hub

In a nutshell, Cosmos Hub bills itself as a project that solves some of the hardest problems facing the blockchain industry. It aims to offer an antidote to slow, expensive, unscalable and environmentally harmful proof-of-work protocols, like those used by Bitcoin, by offering an ecosystem of connected blockchains. The project’s other goals include making blockchain technology less complex and difficult for developers thanks to a modular framework that demystifies decentralized apps. Last but not least, an Inter-blockchain Communication protocol makes it easier for blockchain networks to communicate with each other — preventing fragmentation in the industry. Cosmos Hub's origins can be dated back to 2014, when Tendermint, a core contributor to the network, was founded. In 2016, a white paper for Cosmos was published — and a token sale was held the following year. ATOM tokens are earned through a hybrid proof-of-stake algorithm, and they help to keep the Cosmos Hub, the project’s flagship blockchain, secure. This cryptocurrency also has a role in the network’s governance.
