Yes, that's right. Users can register and resolve human-readable names to complex Ethereum addresses using the Sui Name Service (SNS). The platform is built on top of the Ethereum blockchain, a decentralized, distributed ledger technology that allows transactions to be recorded in a secure and transparent manner.

In order to register and resolve names, the SNS uses a smart contract on the Ethereum blockchain. The SNS creates a mapping between a human-readable name and an Ethereum address when a user registers a name. With this mapping stored on the blockchain, it is possible to look up an Ethereum address associated with a given name decentralized and securely.
