Namecoin

Namecoin is one of the older cryptocurrency projects, and that history is the main thing to know about it. By our assessment, its most concrete claim to fame is the attempt to attach identity and naming to a blockchain, instead of using only a plain payment coin. That makes it interesting to people who care about decentralized name systems, but it also leaves it narrower than the big-purpose coins that everyone treats as money first. The trade-off is obvious in use: you get a specialized network idea, and you give up broad everyday utility. In practice, it is the sort of coin that tends to attract curiosity from crypto-watchers more than ordinary users. Compared with mainstream tokens, Namecoin matters more as a concept than as a daily tool, and that keeps its ceiling fairly low outside its niche.
