Might be a good idea to not add this to the BTC code anytime soon. Too much privacy might be counterproductive, at least with the government. To have it as a web thing makes some sense.

I guess people who want total anonymity will find a way to do that.

with BTC people should have the freedom to have privacy. And Bitcoin is currently less anonymous than credit cards. Zerocoin might solve some of those problems.

This is false. Bitcoin is significantly more private than credit cards. Credit cards, by their nature, are intimately connected to your real world identity. It's literally impossible for them to be private from third parties. With Bitcoin, even as it is, at least some degree of anonimity is possible regarding any person or organization that is not directly part of the transaction, although it often takes some degree of extra care.

Okay, I'm going check the wiki and stackexchange now.

EDIT: That didn't help at all. Well, reading the paper and the blog post helped to explain it to me.

How could a BitCoin exchange be traced? You put in the address, your number goes down, their wallet goes up...

Would someone just need to watch for bitcoin-type data being sent?

blockchain.info

Also, the whole point of bitcoin is that everything can be traced. This is the point of the blockchain. Every coin is traced and you can trace back and eventually you'll get to a mined block. This is how we prevent double spends. Keeping track of all the outputs. You can find out how many bitcoins are at each address. You can trace where each input of that address came from.

Bitcoin is actually in a way less transparent than credit cards and cash.

Currently, to gain anonymity you would need to use a laundry service. But you have to put your trust into the laundry service, that they don't run away with your coins or that they don't keep logs of who's coins go where.

Looks like the public at large might be so soured on bitcoin that another name and improvement
like ZeroCoin might be a good idea to keep cryptocurrencies going...
but why ZERO? why not call it something more positive?

Bitcoin don't need this

Everything is just fine the way it is

WE GOT ENOUGH BITCOINADDRESSES

try your magic trick in the circus Grin

Speak for yourself. I can generate addresses all day, it is not going to break the connection between the transactions.

IMO competition is good in currencies. Most people I talk to in the states don't even realize that there is other money besides dollars which always baffles me. Are we really that uneducated???!!!

Zerocoin isn't really an alt coin. It'll be pegged to bitcoin.

There's nothing mysterious about how it works:

Quote

Zerocoin works by allowing Bitcoin users to leave their coins floating on the network for someone else to redeem, on the condition that they can redeem the same amount of Bitcoin, similarly left floating on the network, at an arbitrary time in the future.

In other words, you leave your bitcoins somewhere in the network, to be picked up and used by some stranger using the addon. Then you use some other stranger's bitcoins.

What I don't like about zerocoin is:

Quote

"Zerocoin would give you this incredible privacy guarantee, then we could add on some features which let the police, for instance, to be able to track money laundering. A back door."

I believe letting someone do searches on data meant to protect privacy is against protecting privacy.

was just going to add this, they are obviously just doing this as an academic thing then, because its pretty pointless to make a privacy system that can then be made not private.

-or maybe they want us all using this so they can track us more easily with there back door Huh

More likely they want funding to develop the code, and then an open source clone without the backdoor would be devleoped and would be the actual system used, and the banksters get left with notihing of useful value for their "investments". It's open source, dude, if there is a backdoor, it can be found in the code and either altered or exploited. IT's not really going to happen in practice.

Hmm it's not explained technically in the article...

The key is that it does this without introducing any new centralised elements into the network

It sounds like you send your coins to some huge wallet, and you can also send instructions to the huge wallet to spend your credit. I don't see how this could be done in a distributed fashion yet (not requiring a central server). Perhaps it's some trick with incomplete transactions / oracles:
