True though that the technology also needs to advance as it also does for other coins with active development. Standing the test of time is one thing, active development the other.
active development. I've already mentioned the ConsensusJ light client.
The full client, namecoin-core
follows Bitcoin development closely, the last update was 7 days ago.
The problem, for me, is still usability. It is still too difficult for the "general public" to use Namecoin. The Blockchain DNS project (browser extensions) I mentioned earlier is a big step forward as it works on two of the most popular browsers and works out-of-the-box. I think porting the Blockchain DNS extension to the remaining browsers (Safari and Edge/IE) and with a stable light client (ConsensusJ or Electrum) Namecoin can be a success.
The main reason namecoin is not heavily traded is because traders don't have a lite client to store their coins off exchanges.Same goes for regular Joe who has no interest in bit/dns and only wants a solid coin to use to buy his trash on the internet wherever a shop accepts namecoin.It all boils down to economics and the whole namecoin economy is wrong by only appealing to a niche audience.We are not all geeks but have a lot of respect for the developers of this legacy coin and many want to trade and use it for non geek stuff too.
Firstly, there are so many scam coins (check coinmarketcap), which have a higher market cap than Namecoin. Those projects are traded for speculative reasons, the additional benefit is limited, especially compared to Namecoin. You can't even buy something with those coins. Namecoin was once traded on kraken. They removed it. I do not know why.
Secondly, go back a few pages. There, we discussed ways to make Namecoin and the corresponding DNS more prominent. Even though our result is still limited. But I hope this will change in future.
Thirdly, I think, that there is relatively much development under way. E.g. I am looking forward to Namecoin version 0.15.99, which seems to be still in beta state (https://namecoin.org/2018/02/01/namecoin-core-0-15-99-name-tab-beta1.html
Fourthly, the next Namecoin halving is scheduled for end of October.
Thus, it is time for this coin to shine again (imho)!
