The Cosmos SDK has a good standard tutorial, which builds out a sample name service application. To provide a nice transition for existing SDK developers, we will demonstrate implementing the same application using CosmWasm. This is a useful tutorial to demonstrate basic concepts and applying the skills that you learned in the introduction. We will also be producing another tutorial for deploying and using an ERC20 contract, which may be more familiar to those coming from an Ethereum background.
As in the original tutorial, you will build a
functional application running on Cosmos SDK. In this case we will
cosmwasm to deploy a rust contract rather than develop a native go module.
In the process, learn the basic concepts and structures of CosmWasm. The example will showcase how quickly and easily
customize a default Cosmos SDK application using CosmWasm smart contracts.
By the end of this tutorial you will have a functional
nameservice application, a mapping of strings to other
map[string]string). This is similar to Namecoin, ENS
, IOV, or Handshake, which all model the traditional DNS
map[domain]zonefile). Users will be able to buy unused names, or sell/trade their name.
