Informal is a core contributor to Cosmos, where we develop interoperable blockchain systems by heavily relying on formal verification tools and techniques.
The Cosmos technology stack, including Tendermint Core, the Cosmos-SDK, IBC, and the Cosmos Proof of Stake modules, is an industry leading Go toolkit for building, deploying, and running blockchains. This technology is used today to secure many billions of dollars in cryptocurrency market capitalization.
One such blockchain is known as the Cosmos Hub, with its native ATOM token. Launched in 2019, the Cosmos Hub was one of the first production Proof-of-Stake blockchains, and today has one of the largest and most decentralized validator sets in the blockchain ecosystem. It is central to the Cosmos community as the blockchain focused primarily on providing a high security environment for connecting into the emerging Internet of Blockchains - the interchain.
The goal of the Cosmos Hub is to provide a high security base-layer environment to service the needs of the many dozens (and eventually hundreds and thousands) of IBC enabled blockchains by providing interoperability services. The Hub will make it easy to launch new chains, to connect with many chains from a single integration point, to simplify access to diverse interchain services like liquidity and other DeFi applications, and more. For more on the vision of the Cosmos Hub, see the blog post, The Cosmos Hub is a Port City. You will help us build out these features.
