Improoving Namecoin fungibility and privacy

Post by virtual_master »

I can understand that so many people are worried about the privacy and the future of their coins(with blacklisting, redlisting) and I would suggest that Namecoin should give for the users increased privacy, which is above the level of the other cryptocoins.
This way those who don't feel secure by the others should find with their investitures a secure asylum by us.

Adam Back, who developed the Hashcash(https://en.bitcoin.it/wiki/Hashcash) says that loosing fungibility could destroy Bitcoin: https://bitcointalk.org/index.php?topic=333882.0;all


Some relevant projects to improove privacy and fungibility:
CoinJoin
https://bitcointalk.org/index.php?topic=279249.0
https://github.com/calafou/coinjoin
CoinControl
https://bitcointalk.org/index.php?topic=144331.0
http://sourceforge.net/projects/bitcoincoincont/
ZeroCoin
http://zerocoin.org/
https://github.com/Zerocoin
Originally they intended to ride on the Bitcoin blockchain but in connection with the recent scandal they decided to stay on their own feet and make their own coin.

What do you think about improving fungibility and privacy of Namecoin ?
CoinJoin could be easier implemented then the other projects.
Namecoin was not intended primary as currency but could do that also and those who don't feel safe any more by Bitcoin maybe can find home by us.
This way by Bitcoin would only remain those who like or at least accept regulations and they don't need to fork any more.
So we would help Bitcoin also this way.

CoinControl would be cool... but I guess we first need to increase use one way or the other.

There is a lot of potential for ZeroCoin and Namecoin implementation I believe. Not to mention a need for something like that.

What's the point of owning an "unseizable domain name" or piece of digital property if "they" can simply trace the purchase and/or renewal of that digital property back to your bank account?

CoinControl, CoinJoin and ZeroCoin seems to be the most active but ZeroCoin is very sophisticated, resource intensive and most difficult to implement.
1. CoinControl would already work when integrated in the client, is understandable and practical. So it would be also my first choice.
2. CoinJoin is also a relative easy and working concept and is already implemented by blockchain.info. This could be the second step.

Would be cool to see CoinControl / CoinJoin / Zerocoin in Namecoin. CoinControl and Zerocoin would probably be best added via libcoin, to avoid duplicating effort with other coins. CoinJoin could be done independently.

And yes, I completely agree that there's almost no point to having Tor/I2P domain support in the d/ namespace if the names can easily be traced.

What would a libcoin implementation of CoinControl do? I thought CoinControl is more about the UI, since the backend automatically has to deal with outputs individually. So what would you expect a "backend" implementation of CoinControl to do? I think more that CoinJoin could be implemented in libcoin, especially if a standard protocol for brokering joins in a P2P fashion (with secure multi-party sorting and blinding) can be worked out which would then be interoperable between multiple CoinJoin implementations.

But in general I fully agree that it would be very great to have better anonymity in Namecoin, especially also for the reasons already mentioned (names may be even more crucial than money in terms of anonymity for certain uses).

I generally meant that since CoinControl is part of the main client and isn't specific to Namecoin, putting it in libcoin seems reasonable since that way Bitcoin and other cryptocurrencies benefit from the code more easily. Of course, this is dependent on libcoin integrating the Qt GUI.

Ah ok, I didn't think that libcoin would integrate any UI at all (seeing it more as a backend library). But if it does, then I completely agree that it makes sense to implement CoinControl there.

I think snailbrain said something about libcoin planning to integrate the GUI in the future; this was in the context of whether the Namecoin-Qt "Manage Names" tab could be added... but I don't fully remember details. (@snailbrain, want to refresh my memory?)

EDIT: Here's snailbrain's post: https://dot-bit.bit/forum/viewtopic.php ... 27f3#p6806 . So yeah, sounds like libcoin is planning to integrate the GUI.

:( Oh oh. It looks bad for Bitcoins fungibility.
