XNS — Ethereum's Naming Layer

XNS is a naming service for Ethereum that lets users send and receive crypto using a name such as alice@xns instead of a 0x address, with names registered once and owned permanently. The site says names cannot be sold or traded, and that 80% of every registration fee is permanently burned, reducing ETH supply. Registration starts at 0.001 ETH, and the page presents XNS as a replacement for ENS, which it calls broken because names expire and can be reassigned if not renewed.
