CosmWasm is a smart contracting platform built for the Cosmos ecosystem. Simply put, it's the Cosmos (Cosm) way of using WebAssembly (Wasm) hence the name.
CosmWasm is written as a module that can plug into the Cosmos SDK. This means that anyone currently building a blockchain using the Cosmos SDK can quickly and easily add CosmWasm smart contracting support to their chain, without adjusting existing logic.
