The Alias System can be used to define mapping of names (“aliases”), unique within each child chain, to arbitrary strings or pieces of data, implementing a decentralized on-blockchain naming system. Much like the DNS, such aliases can be used to map a domain name to IP address, hold the current value of some important publicly announced data (e.g. the latest Ardor release checksum), or simply be used as an easy-to-remember nickname for the account that owns the alias. Each child chain has its own namespace of aliases, but only the Ignis aliases can be used as a shortcut for logging in or as nicknames for transaction recipients.

The Alias System is a feature on the public blockchain Ignis and available to all child chains on the Ardor Platform
