Complex addresses (e.g. cryptocurrency, network, physical) are difficult to share and remember, which adds risk to their use. The Decentralised Address Resolution Protocol is being designed to provide easy to remember Address Names to help mitigate against these problems
While some services already exist which focus on simplifying the use of cryptocurrency addresses, they are not implemented on a third generation blockchain and use smart contracts to store records on the blockchain that map a friendly name to an address. While this technically decentralises the name resolution service, it unnecessarily adds bloat to the blockchain with data that doesn't necessarily need to be immutable and can also add cost through the use of gas.
