Our research provides a comprehensive overview of the Cosmos ecosystem and its foundational Inter-Blockchain Communication Protocol (IBC). They explain how IBC enables different blockchains to communicate securely and reliably, highlighting its trust-minimized nature through light clients and relayers. The articles also trace the history of Cosmos and IBC, from the invention of Tendermint by Jae Kwon to the development of the Cosmos SDK and the concept of Hubs and Zones for scalable interoperability, ultimately showcasing IBC's role in creating an interconnected Web3 landscape.
