There have been a few name service experiments in Cosmos, but none of them have really gotten much adoption. This is because names, like Internet domain names, need a well established use case and have to be integrated into the rest of the infrastructure. Internet domains don’t make sense if websites don’t exist. Likewise, web3 names don’t make sense unless they can be used somewhere. On Ethereum, ENS didn’t really take off until NFTs gained traction. Names are useful for NFTs because identity is an inherent property in many NFT use cases.
