How long does it take to resolve a namecoin key=>value pair? Considering the variable speed in these sorts of decentralized networks, is there a noticeable lag when you initially request a .bit website?

Sure, decentralized networks can have variable speeds, but you could put a caching layer in front and the problem should be solved, no? The writes will be variable, but reads don't have to be.

It's very fast, and if it's not fast enough, one can build an optimized data structure in another program.

Just as fast as a DNS lookup. It can be cached anywhere (even locally, with your own name server on your own machine).

It's also almost exactly the same as DNS regarding name changing. You have to wait about 10 minutes for the blockchain to register a name, and then about 24 hours before all the cache servers update it.

I have been looking at *coins for a while and the implications of the blockchain-based concensus system are interesting.

The system really maps the real world onto computers very well, in that it reduces what used to be technical issues to "political" issues. These systems work on concensus, and as such, require a significant amount of interested parties to work in the expected way. They are very much subject to network effects that only occur after critical mass is reached.

Namecoin, in particular, was subject to a major security issue last year: http://www.reddit.com/r/Bitcoin/comments/1ohyom/fatal_flaw_i...

Blockchains are being used to implement solutions to different problems, and they could really solve some significant problems such as decentralized identity and reputation management (!). The difficulty lies in creating a significant enough "currency" so that miners will become involved and make the blockchain stable and reliable.

Bitcoin is a currency in a much stronger sense than namecoin or any other of "not-really-money-coins" around. I wonder if piggybacking on bitcoin might actually be the solution for this situation (i.e introduce other information in the bitcoin blockchain instead of using a brand new one).

Sadly, adding external information to the blockchain could be construed as "spamming the blockchain" and therefore not deemed worthy for inclusion in the bitcoin blockchain by miners. So there is a big challenge there.

The blockchain is only used as an authoritative source. You don't really look up names in the blockchain, you use a vanilla cache for it.

Author of the original article here. Namecoin is actually merge-mined with Bitcoin, so miner participation is not a serious problem. There's no way you could have known that without happening to know that, though, and I agree that this is an issue for a lot of new blockchain-based technologies.

Maybe I've misunderstood it, but how does merge mining create an incentive to mine namecoins? I figured all it did was make it "cheaper" to mine namecoins by "reusing" work done for the bitcoin blockchain. In order for the namecoin network to function, you still need to actively get involved with it.

Here's some information on merge-mining for anyone else involved: http://bitcoin.stackexchange.com/questions/273/how-does-merg... http://dot-bit.org/Merged_Mining
