At Interchain GmbH, we are responsible for stewarding some of the most foundational infrastructure for blockchain ecosystems. Our work helps secure over a billion dollars in value across a variety of major blockchain projects, including Cosmos, and we are pioneering new protocols for interoperability across the entire blockchain ecosystem. Our vision is to create a new interconnected ecosystem, a new internet of blockchains: The Interchain. Our products include Tendermint Core, a groundbreaking, Byzantine-fault tolerant consensus protocol; the Inter Blockchain Communication protocol, a reliable, ordered, authenticated cross-ledger data transport protocol; and Gaia, the software that powers the Cosmos Hub. All of our work is open source, and we code primarily in Go. We design protocols and architect systems, while working closely with a variety of external contributors and users from around the world. If you like working with distributed systems, databases, blockchain protocols, or cryptography, we think you might like working with us!
