I've created a "btm/testing" name for testing. It should show in about block 93985 where you can see it the magnet links it has posted with: namecoind name_history btm/testing You can list the "btm/" namespace with: namecoind name_filter "^btm/.+" Now there needs to be a website that scans that namespace, does a name history on the names, and provides it in a pretty format. |

not quite sure yet but my gut says the second variant is more likely to succeed
I would keep it simple, though, and start with one protocol per namespace. btm/satoshi : {bit torrent magnet}
>Maybe an option to add an address to the value for users to send namecoins to as a means of voting.
no need for that, you can simply use sendtoname for a tip
Good point about 'sendtoname'. Using a separate protocol per namespace is also a good idea. Given magnet url's have a "dn" key for giving the full name I'm wondering if it's even worth having JSON as the value. Just having the magnet link gives all that's needed. |

Alternate cryptocurrencies / Altcoin Discussion / Re: Namecoin's Dot Bit Domain Name Cypersquatting

what's to stop someone forking the namecoin project and altering the code to make new .somethingelse domains? agreed it would potentially run into the same situation.. but is there anything we can learn from the namecoin experiment?
Namecoin doesn't really have the notion of .something. That mapping is done via other software. Namecoin just provides a way to map a name to a value stored in the blockchain. By convention names prefixed with "d/" are mapped to domain names in the real world with .bit as the TLD by various pieces of software. There's nothing to stop you from using namecoin to purchase domains with different prefixes and there are already examples of such in the blockchain. If you wanted to immediately devalue all the squatters names you could come up with some DNS software that maps a different namecoin prefix. If your DNS translation software gets popular then that would become the defacto "namecoin domain name" system. |

Isn't this the kind of thing namecoin should work well for?
Put the IP address and port number for your torrent, or for a datafile about the torrent, into the namecoin dataspace?
I agree that namecoin would be a good start for experimenting with this. There's a number of approaches that could be taken. Some ideas: - The namecoin 'key' is a torrent name with the value being the magnet link. This is simple but has a few disadvantages. The owner of the key has to update it every 36,000 blocks for it to remain alive. Only that owner can modify the magnet link if it changes. Multiple people will store information for the same file with slightly different key names. Spammers can create fake magnet links easily for popular filenames, or squat on filenames (eg. future episodes of tv shows or movies about to be released).
- The key is a username of a person publishing links. The value is a datastructure (JSON?) that holds the link type (magnet, mega, freenet, http, etc), the URN (magnet link, freenet address, etc), a title, tags and maybe other things. A user can then filter by the namecoin key if they find a user that publishes torrents they like. Spammers would need to register their own username and people will learn which are bad and ignore them. Adding links is done via a name_update command. You can get a list of all links for a user by doing a "name_history" on their username. This can sit under a namecoin prefix like "fileshare/". I registered a fileshare name to show an example. Downsides are that a name_update can only have one pending for a given key per block. This could help cut down on spam updates though. Another downside is that it requires a name_history to get all entries and isn't as simple or efficient as iterating over a namecoin prefix to get all keys.
As an example of the second option, running this namecoind command will show an example entry: namecoind name_filter "^fileshare/.+" That example adds a "command" entry which I though could be used to add/delete/modify items but I'm not sure of the utility. It also might be worth encrypting or obfuscating the entries. Maybe an option to add an address to the value for users to send namecoins to as a means of voting. |

is it impossible to change your id's bitcoin address.... wtf
That's by design. It means it's impossible for a hacker to change your bitcoin payout address. Allowing changes would also require users to have passwords which adds another whole level of security that's uneeded in the current design. Just create a new username if you want to change things. |

Very interesting, simple interface. But why these exchanges are independent, is there any way share the balances across these bitparking exchanges? Otherwise, it is needed to transfer them by using the network and it's slow.
I can imagine it's safer this way. But, I guess it would be nice to move your BTC around. This is mainly because I first implemented a namecoin exchange back when it was the first alt-coin. When the others started coming out I just modified that exchange - the changes to add multiple currencies to it would be more extensive and not something I was keen on doing at the time. At some point I may rewrite things to make multiple currencies easier but at the moment there's too many other projects going on. |

That is cool, but I don't feel like letting dataminers and profilers at Google / Yahoo / OpenID know I'm using the exchange.
You can use an anonymous open id provider or host your own if that's an issue. But that aside, that's fine, I understand your point of view. I prefer not handling passwords on the exchange. |

Alternate cryptocurrencies / Altcoin Discussion / Bitparking Terracoin Exchange [closed]

See my message here for details on the closing of the exchange: Recent events have shown that running an exchange is way to risky and stressful to me in the current alt coin climate. Prices have risen to a point where I'm not comfortable I can provide a reasonable level of service. To this end I'm closing the exchange and encourage all users to move to vircurex. The following details are on the exchange site: 2013-04-05: The Bitparking exchange is closing down. I've decided the risk involved in dealing with the current high prices for the alt coins has moved from the 'fun hobby' level the exchange originally started with and requires a more serious approach to operation. I've been in contact with the Vircurex exchange and I encourage all existing customers to move their funds and continue trading their.
The exchange will close trading Friday 5 April 2013 22:00 and new deposit addresses will not be able to be created. Trading operations will also be disabled. Withdrawals will be available for a few days after that at which point the exchange will close and all funds sent to their emergency withdrawal address. Withdrawal fees are removed during this period. Thanks for using the exchange and enjoy a better and more professional experience at Vircurex.
