Yes, ideally the namedb should just track the epoch value so it doesn't need to be looked up separately. The name history thing is just a way it could be implemented now.

What is a "Name Epoch"? A name epoch is a period of 36,000 blocks. The epoch number would be floor(block height / 36,000), currently 5, soon to be 6. A registration can be uniquely identified by (name, epoch of name_firstupdate). If the name expires and is re-registered the epoch will be different. ...

Is the Namecoin-Qt logo the same as the one on the wiki and main site? I like that one.

If the Merkle tree is constructed for every block (needs a softfork) and contains all current names, then if you get a reply with a branch you can verify that the value you got is indeed the latest name. The only thing for which a server can lie to you is if it tells you the name does not exist (or...

Bloom filter wouldn't be a good idea - they can have false positives, so you might identify a name as not being the latest version even though it is.

The 6 prefix is used by BIP38 encrypted private keys. What about lower case s for the prefix?

Should we support P2SH in name operations? E.g.

[name operation] OP_HASH160 [hash] OP_EQUAL

P2SH for names would be good to have.

If anyone else has this problem, it's *probably* due to some sort of wallet corruption. I am not 100% sure of the cause, but we've had at least one instance where we were able to recover from the situation. Please hop on IRC if you're having this problem, I have some recovery tools but they're finic...

Also, on if Alice makes a sell offer and Bob accepts it, Charlie can sever Bob's portion off of the transaction, replace it with his own, and try to double spend. May not really be a problem since Charlie still has to pay for it. Buy offers do not have this problem.

Possible problematic scenario: Alice makes an offer to sell d/example for 10NMC and posts it somewhere Bob makes an offer to buy d/example for 25NMC and posts it somewhere Charlie finds both these offers and makes a transaction where Bob gets d/example, Alice gets 10NMC and Charlie gets 15NMC minus ...
