Title: Untaint for a fee using out-of-band transactions and large mining fees Post by: eldentyrell on March 04, 2014, 10:03:45 AM I think that is tinfoil-hat talk. I believe most people want a free and fair system, and so bitcoin will stay free and fair. Unfortunately I don't think so. Sadly most people today would rather have security than freedom. That sucks, but it's how it is. a bit of taint was peeled off every fee-paying transaction included in the block. So each newly generated coin can be traced back to a lot of addresses…. It's not very useful to define taint in this way, so blockchain.info for instance does not include it. If you perform taint analysis on a newly generated coin, you'll find zero taint. Probably because blockchain.info's taint analyzer has very different goals than governments and the legacy financial system do. Be assured that if a taint system is imposed, it will deal with transaction fees. Bitstamp is already demanding receipts for mining hardware (https://bitcointalk.org/index.php?topic=406908.0). This can be done. Semiconductor fabrication is already heavily licensed. I have to be pretty creative with the EAR paperwork when taping out to overseas foundries. It's really a shame that the Zerocoin people are taking the attitude of "claim priority (first to publish), somebody else can do the heavy lifting of actually making it work". Satoshi did it right, he did both, and he changed the course of history. People like Satoshi are the ones who created the Internet, and I see fewer and fewer of them in academia with each passing year.

Zerocoin recently became much more practical with a 344 byte signature instead 40 - 50KB. I believe the details are not yet published? http://www0.cs.ucl.ac.uk/staff/G.Danezis/papers/DanezisFournetKohlweissParno13.pdf The remaining problem I have with Zerocoin is at least two-fold.

Tainting won't be solved by the idea in the OP. (besides it is silly, easier to just buy the newly minted coins from he miner) It will only be solved by adding something like Zerocoin to the blockchain + very strong building IP address obscurity. Thus the relevance of the impossibility to fork Bitcoin and the importance of freedom to make a better altcoin (even it is just really Bitcoin 2.0). Btw, here is some more technical insight on my prior post about Zerocoin: https://bitcointalk.org/index.php?topic=495527.msg5508024#msg5508024 https://bitcointalk.org/index.php?topic=500994.msg5518821#msg5518821 Title: Re: Untaint for a fee using out-of-band transactions and large mining fees Post by: AnonyMint on March 04, 2014, 05:32:13 PM He did it again.

Yes, I have failed as a moderator! I don't like deleting comments, but it is important to keep the thread on topic. This thread is about using out-of-band transactions and large mining fees to untaint coins. Edit: I just deleted a post from AnonyMint, but then it hit me that with a slight twist it was actually on topic and a good idea (now I've really failed as a moderator lol). Instead of sending the tainted coins with a large mining fee using a non-public backchannel, just send the coins normally to the untainting service. They would then perform the large-mining fee transaction themselves. The fee they charge for the service would already take into account the expected loss to the orphaning. In other words, you are exchanging old coins from the miner for newly-created coins (at a small fee). The miner doesn't care about taint because the chain of taint breaks using the large-mining-fee method that I proposed earlier. And who took it off topic? (look in the mirror) Then you did exactly what you were writing you weren't going to do (delete my post) You change the facts as fits to your errors and necessary covering of your arse. |
