Linking your account addresses with your web3name and DID – your unique decentralized identifier – makes it easier for others to recognize you. Your DID can also be publicly linked with credentials like your email address or social media accounts, adding a further layer of verification.
Each DID can only be linked to one web3name, as they are both unique and form the core of your digital identity. Your web3name can then be linked to multiple account addresses you want to publicly associate with your name. These addresses can be on KILT and across the Polkadot and Ethereum ecosystems.
This feature can be especially useful for collators, validators, or those offering services on-chain. A simple search of the name or DID via the w3n.id website shows the publicly-linked information. Addresses, credentials, or names can be unlinked at a later date.
Note, since anything linked on the blockchain is public and therefore a permanent record, be sure to link only the addresses or credentials that you want associated with your name. Also, account linking does not permit sending or receiving funds via a web3name: to do that, see w3ndi.
Account Linking is a feature of KILT Protocol and was built by BOTLabs GmbH, the initial developer of KILT Protocol.
