We explore the dynamic relationship between Cosmos and Bitcoin, examining how they can mutually benefit each other. We trace Cosmos' journey since its 2017 launch, its relationship with BabylonChain, and the potential shift of Bitcoin to Proof of Stake. Additionally, we discuss the future interplay of blockchain ecosystems like EVM, Solana, and CosmWasm, and review key concepts like economic finality, restaking, and the Osmosis roadmap. This interview features Sunny Aggarwal, whose history includes working at Tendermint, helping build the Cosmos SDK, IBC, and launching the Cosmos Hub (aka Gaia). He is also the co-founder of Osmosis, the Cosmos DeFi hub.
