[announce] Namecoin - a distributed naming system based on Bitcoin

[midnightlightning]

That's 74 seconds after the timestamp of 24191. My retargeting math has worked for all the previous retargets, so why did this one go wonky? Was there some different logic in place for this block round that allowed a slightly different difficulty retarget? Is this a rounding error (after multiplying the old target by the actual time spent, do I need to truncate it before dividing it out)?

Block 22175 is 74s before block 22176 (time of block 22175 = 1318761208).

It is related to a bug known as "retarget hole"/timetravel due to merged mining :
https://github.com/namecoin/namecoin/commit/436f571d41cc53844d482eeef0069a3ca94e08f8
https://bitcointalk.org/index.php?topic=43719.0
https://bitcointalk.org/index.php?topic=43465.0 (first post erased...)

So, after block 19200, go back 2016 instead of 2015.

Thanks! That seems to have fixed it, but for right now the three hard-coded IP seed nodes for Namecoin are all refusing connections, so my client isn't finding any peers to connect to. Was there a new version adopted that change the ports or magic bits of network communications?

Check commits from days 24/05 (mainnet) & 25/05 (testnet) to find the right magic numbers : https://github.com/khalahan/namecoin/commits/namecoin_v0.8.2rc2 (but they have not changed).
If you reject merged mined blocks, this is another reason why your peer disconnects itself from remote nodes.

So what exactly determines the cost of a .bit domain? Is it hardcoded into the miners software?

Most sites will say it costs 15 NMC per year, is this a coincidence that converted to USD it costs the same as a .com domain?

[nelisky]

What about normal transfer fees (not name related), what's the schedule there? I'm feeling too lazy to go through the code, unforgivable I know, but it is Friday...

With 15 NMC you can register over tausend .bit domains for a year if you make yourself from your wallet.
You can make it from your Namecoin client and there is a description how to make. But if you prefer the easiest way then you pay 0.1 BTC for a service and they do it for you.
So if you make yourself it will be 1000 times cheaper then a .com domain and will not take more time.

Over 1000, as in you just started speaking German halfway through the sentance? I found this graph http://dot-bit.org/HowToRegisterAndConfigureBitDomains and the chart says the it will in total cost 0.015 NMC. So where are there services that charge 15 NMC for a .bit domain, if all they are doing is hosting a node, keeping the blockchain, and making it easier for you to register a domain?

i think you mean "why" there are services, that charge more...

well, they are services... you pay for the easy of use,

hopefully this will be fixed soon, the wallet upgraded and nmc will become more popular.

keep in mind nmc is more complex than btc!




btw, i just opened nmc testnet and its stuck on block 23152 (3days ago) and not downloading, even thought it's conected to 5 nodes.

Indeed, on a SnowLeopard the N logo shows up for half a second, and then it "quits unexpectedly" with an
Exception Type:  EXC_BAD_ACCESS (SIGSEGV)
Exception Codes: KERN_INVALID_ADDRESS at 0x0000000000000028

That's just a compilation problem, I think. Apparently there must be a makefile for the Mac somewhere?
(I know, SnowLeopard is not relevant anymore. It's just I can't get hold of a Lion/MLion machine at the moment  )

Yeah, unfortunately a lot changed in Lion with the introduction of the LLVM compiler and its libraries, and now it's hard to compile anything on Mountain Lion to be backward-compatible. Getting wallets compiling on a VM running Snow Leopard is definitely on my to-do list.

Been testing snailbrain version with all the RPC commands added. So far everything is working pretty well, there's just one small issue which I'm not sure relates to snailbrain's updates or not, but is kind of problematic for me.

Regardless, I'm calling the 1000 NMC bounty I offered as fulfilled. Can you provide an address for sending it, snailbrain?

Now, the problem I'm having is (using addresses imported without private key, not sure if that's relevant) when sending a transaction that has the same address in inputs and outputs, for example returning change to the sending address. When I do that the sending address is empty as far as the daemon is concerned even though the transaction is properly formed. The only way to see the unspent output again is by rescanning.

Addr1 10 NMC
 -> Addr2 9 NMC
 -> Addr1 1 NMC

Addr2 has 9 NMC, Addr1 is empty until I restart with -rescan

Addr1 10 NMC
 -> Addr2 9 NMC
 -> Addr3 1 NMC

Addr1 is empty, Addr2 has 9 NMC, Addr3 has 1 NMC as expected.

Snailbrain could you help out bytecoin? We have a bounty.

looking into this.. doesn't seem related to changes we have done.. but still checking..

edit: removed some stuff for now

much appreciated



Hopefully Khal can add to proper repo to get the rest of bounty to fulfil moa's bounty too xXx (or can wait for next update)
The dev has been working extremely hard

the coder is very busy atm .. concentrating on NMC above all.. but you can send a link in PM

nelisky : so I just wanted to check that you're satisfied that your requirements have been fulfilled and tested for the namecoin-qt client, extra functions, open source, no hidden code, etc? If so I've agreed to put 500 nmc for namecoin-qt client code to get in to this state which I will happily pay.

Also I have another 250nmc for this namecoin-qt to get merged back into official namecoin/namecoin github repository and another 250 nmc for it to rebased on top of the v0.8.2 bitcoin-namecoin compatability (i.e. leveldb, etc) mods that khal is currently working on.

Thanks for all your work so far snailbrain, this is excellent

I'm still not 100% sure there's nothing broken, but all the commands implemented work as advertised and I couldn't find any obvious "hidden code". This is no guarantee however, and before I get this into a production environment I'll do a full code review for my own benefit.

i wish i could take the credit..
unfortunately the main credit goes to vinced, khal, and all you guys (virtual-master, moa, nelisky, phelix and many others)... AND the coder of Namecoin-qt who has done an excellent job so far, he is very knowledgeable and has worked day and night to get this right (and there is much more to come)

You can give me credit for a Jump Start <3  ---- and I will continue with the dev in collaboration with the community to make sure we continue to support NMC into the foreseeable future.
 
I cannot understand why Namecoin is not the most talked about crypto of ALL..
I'm sure that those people that have given NMC a miss will be disappointed in the future

I don't know about everyone else.. but I'm excited.

[bitpop]

Very excited.

[ninjarobot]

Namecoin has tons of untapped potential. I'm really happy this is still being actively worked on. Thank you!
