Topic: Is it really Bitcoin Anonymous? - page 2. (Read 378 times)

You speak too scientific a language, it's quite difficult for me. And not just me, most people do not know how to do this. I'm just trying to understand how the blockchain and bitcoin. "Blocks, knots" is difficult for me.

People Framing themselves and lose their anonymity. They publish his bitcoin wallets on all Internet platforms (Bitcointalk, Reddit, Facebook, Twitter, etc) [/i]

It turns out that thanks to our mistakes, we deprive ourselves of the most priority feature in bitcoin - anonymity.

But how to be ordinary users who do not want to show their income from cryptocurrency and transactions on them. How to be in this situation? is there a way?

It's a crude way of anonymity: the "obfuscation" method. To do this, a lot of transactions are made, the purpose of which is to untie a person from a specific address. However, in bitcoin it is very expensive, if at all possible,

Bitcoin is not as anonymous as you are thinking, for ordinary users, it's a great anonymity, for large numbers of transactions are monitored and checked!

I do not really know if bitcoin can be fully anonymous,for now it's simply pseudonymous
  I think the issue is when your identity is related to your pseudonym,then your identity can be traced since its stored on the blockchain network.
  A different pseudonym(address) for every transaction will maintain a fairly anonymous status
 

Bitcoin is pseudo- anonymous. It is not anonymous.

Satoshi had no illusions of this:

Bitcoins are sent to and from bitcoin addresses, which are essentially random numbers with no identifying information.

When you send to an IP address, the transaction is still written to a bitcoin address.  The IP address is only used to connect to the recipient's computer to request a fresh bitcoin address, give the transaction directly to the recipient and get a confirmation.

Blocks contain a history of the bitcoin addresses that a coin has been transferred to.  If the identities of the people using the bitcoin addresses are not known and each address is used only once, then this information only reveals that some unknown person transferred some amount to someone else.

The possibility to be anonymous or pseudonymous relies on you not revealing any identifying information about yourself in connection with the bitcoin addresses you use.  If you post your bitcoin address on the web, then you're associating that address and any transactions with it with the name you posted under.  If you posted under a handle that you haven't associated with your real identity, then you're still pseudonymous.

For greater privacy, it's best to use bitcoin addresses only once.  You can change addresses as often as you want using Options->Change Your Address.  Transfers by IP address automatically use a new bitcoin address each time.

> Can nodes tell which bitcoin addresses belong to which IP addresses?

No.

In the next release (version 0.2), the command line to run it through a proxy from the first time is:
bitcoin -proxy=127.0.0.1:9050

The problem for TOR is that the IRC server which Bitcoin uses to initially discover other nodes bans the TOR exit nodes, as all IRC servers do.  If you've already connected once before then you're already seeded, but for the first time, you'd need to provide the address of a node as such:
bitcoin -proxy=127.0.0.1:9050 -addnode=

If someone running a node with a static IP address that can accept incoming connections could post their IP to use for -addnode, that would be great.

> clients connected through network address translation (NAT)?

Whichever one you've set your NAT to forward port 8333 to will receive it.  If your router can change the port number when it forwards, you could allow more than one client to receive.  For instance, if port 8334 forwards to a computer's port 8333, then senders could send to "x.x.x.x:8334"

If your NAT can't translate port numbers, there currently isn't a command line option to change the incoming port that bitcoin binds to, but I'll look into it.

Request: Make this anonymous?
Posted:Thu 15 of Oct, 2009 (19:58 UTC)

Are there any plans to make this service anonymous?

e.g; Being able to route BitCoin through Tor.

There will be a proxy setting in version 0.2 so you can connect through TOR.  I've done a careful scrub to make sure it doesn't use DNS or do anything that would leak your IP while in proxy mode.

That's exactly what I tried to write in my article. By the way, not only bitcoin, But all altcoins have such essence. I wish I had thought otherwise.

Without using any of the tools to obscure internet activity, how are you going to track me in the following situation.

Set up a node using public WiFi, and a copy of the blockchain I've already downloaded.
Receive Bitcoin into that wallet.
Use the Bitcoin to purchase gold coins.
Wipe the hard drive on the computer with the core node.

Yes you are right, I did not consider the peculiarities of these coins. For the Monero I heard a long time that it is used to pay on the black market.
But still, any contact with the exchange or Fiat money, you can immediately recognize.

Not all altcoins either. There are some privacy coins that are anonymous. zcash, monero, electroneum. To name a few.

Of course as soon as you try to exchange it to fiat via a centralized exchange all anonymity is lost.

Think of it this way, Ill know the address that someone sent a TX from, but I wont know the inside leg measurement of the sender

Bitcoin is pseudo- anonymous. It is not anonymous.

When you send to a bitcoin address, you don't connect to the recipient.  You send the transaction to the network the same way you relay transactions.  There's no distinction between a transaction you originated and one you received from another node that you're relaying in a broadcast.  With a very small network though, someone might still figure it out by process of elimination.  It'll be better when the network is larger.

If you send by IP, the recipient sees you because you connect to their IP.  You could use TOR to mask that.

You could use TOR if you don't want anyone to know you're even using Bitcoin.

Bitcoin is still very new and has not been independently analysed.  If you're serious about privacy, TOR is an advisable precaution.
