Bitcoin anonymity


Anonymity is not a prominent design goal of Bitcoin. However, Bitcoin is often referred to as being anonymous. We have performed a passive analysis of anonymity in the Bitcoin system using publicly available data and tools from network analysis. The results show that the actions of many users are far from anonymous. We also point out that an active analysis, using say marked Bitcoins and collaborating users, could reveal even more details.

Bitcoin is pseudonymous. Sending and receiving bitcoins is like writing under a pseudonym. If an author's pseudonym is ever linked to their identity, everything they ever wrote under that pseudonym will now be linked to them. In Bitcoin, your pseudonym is the address to which you receive Bitcoin. Every transaction involving that address is stored forever in the blockchain. If your address is ever linked to your identity, every transaction will be linked to you.






While using bitcoins is an excellent way to make your purchases, donations, and p2p payments, without losing money through inflated transaction fees, transactions are never truly anonymous. Buying Bitcoin you pass identification, Bitcoin transactions are stored publicly and permanently on the network, which means anyone can see the balance and transactions of any Bitcoin address. Bitcoin activities are recorded and available publicly via the blockchain, a comprehensive database which keeps a record of bitcoin transactions.

All exchanges require the user to scan ID documents, and large transactions must be reported to the proper governmental authority. When you use Bitcoin to pay for goods and services, you will of course need to provide your name and address to the seller for delivery purposes.

This means that a third party with an interest in tracking your activities can use your visible balance and ID information as a basis from which to track your future transactions or to study previous activity. In short, you have compromised your security and privacy.

Mixing services are used to avoid compromising of privacy and security. Mixing services provide to periodically exchange your bitcoins for different ones which cannot be associated with the original owner.

There are several different types of Bitcoin clients. The most secure are full nodes like Bitcoin Core, but full nodes are more resource-heavy, and they must do a lengthy initial syncing process. As a result, lightweight clients with somewhat less security are commonly used.
Advertised sites are not endorsed by the Bitcoin Forum. They may be unsafe, untrustworthy, or illegal in your jurisdiction.

You shouldnt trust coin mixers, be very careful with them since they can steal your bitcoins and never send them back to you while they are "mixing them"

Be very careful with mixers.  You send money and hope they send it back.  Research the heck out of it before using, and start small.

Make sure you really need this service before doing it.  Most seem to use them without a true need to be anonymous.

There is a number of incorrect statements in what you say.
While using bitcoins is an excellent way to make your purchases, donations, and p2p payments, without losing money through inflated transaction fees, transactions are never truly anonymous. Buying Bitcoin you pass identification, Bitcoin transactions are stored publicly and permanently on the network, which means anyone can see the balance and transactions of any Bitcoin address. Bitcoin activities are recorded and available publicly via the blockchain, a comprehensive database which keeps a record of bitcoin transactions.
There is no need to pass identifications to buy bitcoins, there is a number of exchange sites that has never asked for any type of identification and im sure it will stay that way in the future to and people dont have to buy bitcoins to acquire them, it is for example possible to mine them annonomously depending on how people set there miners up and there is free givaways like faucets and such where people can get coins to.

All exchanges require the user to scan ID documents
An exchange can not just demand that users from any countrys send them scaned ID documents as that is agaist the law in a number of countrys, if they did that they would be commiting a serious crime and will most likely be charged for it, the exchange can only ask for scanned ID documents from people in countrys without laws against such illeagal procedures.

, and large transactions must be reported to the proper governmental authority
Some countrys dont have such policys some does and it also depends on what you would define to be large amount. Here your for example allowed to take the equivalent of around 12 000$ with you each time you pass the border to another country but there is no law regulating how many times your allowed to pass the border each day so you could if you like walk back and forth past the border 100 times(it would look silly thou but thats about it) and absolutely legal take with you 1 200 000$ if you want to. Simular tings apply for electronic transfers to.
. When you use Bitcoin to pay for goods and services, you will of course need to provide your name and address to the seller for delivery purposes.
That also depends, you dont nessesary have to buy things online, and you dont have to identify yourself to be allowed to buy your groceries and such. If you buy things online the goods dont have to be sent to yourself you can for example send them to one of your companys or a boxadress instead if you would prefer that.

But i do agree that mixers could make it simpler for those that want to stay anonymous in the Bitcoin world and avoid compromising privacy, we dont need a new GDR stasi society in the western countrys of today that some countrys try to create in violation of international human right laws.

but you still need to buy it with bitcoin, they could track that, but if you aim at mining it directly, it would be better in anonimity

No, they can't track that. Once you send coins to an exchange and buy into a different coin(s), it's already almost a done deal.
Once you send Monero from the exchange back to your new address, you could send it to another one just to be sure. Tell me exactly how someone could trace this all back to me?

OP, cryptsy doesn't require verification; at least it didn't use to.

The thing is the exchange would know you came in with x coin at address x, and left with y coin with y address.

If you went to another exchange then changed it again after... maybe more anonymous.  But mining direct into a wallet I think would beat it even on being anonymous.

So what? If I made another account in 5 days and deposited half of that and bought back BTC it wouldn't be suspicious at all.
The chances of them associating that with me is almost zero.

I'm looking at it as worst case scenario.  Let's say some government agency comes along and ask for the data... if you did just one trade yes you could be known with this.   Likely to happen in most cases?  No it is not, but I'm looking at worst case.

You would be surprised how many things have to turn over things.  Heck even this forum turned over info that was needed about bfl.  I'm sure those most of those users did not think some agency would have their PM's about bfl - http://insidebitcoins.com/news/bitcointalk-court-ordered-to-release-butterfly-labs-messages/31814

only mining offer 100% anon, because you never move anything, you just receive them in exchange of your electricity, all other methods have always a tiny % of being tracked back

i could agree that it will be very difficult in some scenario, like with monero, but it's not impossible, also the monero anon tech(ring signature) itself, isn't 100% anon(isn't based on a zero-knowledge scheme)

The problem is the type of people who set up mixers.  Most I don't think are in it to help people remain unknown.  They are in it to make money.

If a government shows up asking for IP logs you know they will be turning it over very very quick hoping to not spend a ton in lawyers.

Also biggest concern is they just stop sending out.  Lets say business is slow, they get a big amount to mix.  They run away with it and any smaller ones that were sent before people realized it.

Just a lot of possible bad things.

About IP and Goverment. There is 2 sites at BitcoinMixers.com that need no registrations. Using VPN/proxy you get your adress for sending BTC and using TOR send them and got your new bitcoins. Simple, yeah?
