Follow these instructions to learn how to access Handshake sites with NextDNS, one of Firefox's Trusted Resolvers. You can run your own resolver as well — Handshake is the only naming blockchain launching with a lightweight recursive DNS resolver. A recursive DNS resolver is a piece of software that can recursively resolve domain names to IP addresses. If you’ve never heard of recursive resolvers, think of DNS as a tree stemming from the root down to the individual domain (pic). Recursive resolvers traverse the entire tree (recursively!) to find the information that a domain points to. The light client can trustlessly resolve Handshake names using only 10mb of memory and virtually zero CPU. It’s the most secure way to use Handshake because it doesn’t require trusting any third party resolvers that can inspect your DNS traffic.
The light client is critical to Handshake's adoption because it drastically increases the surface area of where people can safely use Handshake. You can easily embed the light client into browsers, apps, and embedded devices. Without it, consumers would need to run full-nodes to trustlessly resolve names, and empirically no consumer wants to do that (even if you’re a crypto enthusiast, how many people do you know who run Bitcoin full-nodes?).
