Bitcoin Fog - First Mixing Service in onion
What is Bitcoin Fog?
Bitcoin Fog is internet service in anonymous network darknet. A team of independent and enthusiastic developers created this resource in 2011, thus becoming the first and the most popular bitcoin anonymizer. The main aim was to improve all weaknesses of bitcoin payment system. Now all transactions inside the system can be viewed. The chain of blocks is opened for public access, which means that concerned parties have access to the information about money transfer and balance on bitcoin addresses. There is an opportunity to reveal your identity during exchanging cryptocurrency into fiat currency, if you know bitcoin-addresses.
Bitcoin Fog breaks this chain. Few methods are used for mixing of bitcoins. The first is that incoming deposit is divided into smaller parts. All this parts are mixed with parts of other users in common pool. The process of tumbling is automatic and it takes from 40 to 120 minutes, depending on available reserve. After this procedure, cleaned bitcoins are ready for the withdrawal on your other bitcoin-address. There is no connection between sent and received cryptocurrency.
How Bitcoin Fog works
As usual, the first step is site registration. Then you need to deposit coins to the stated address, and wait for few network confirmations. When it’s done, your money is on your account. Now you can time your withdrawals.
So you deposit few bitcoins to the Fog and wait some time (for amounts above 20BTC we recommend a day, above 50 BTC a couple of days, about a week for 200BTC, etc.). Afterwards, you should make a withdrawal, which is less than original amount, that you deposited before.
Next time you will deposit another part of bitcoins and withdraw again different amount from that you deposited. Now it can be less or more, adding the coins that are left from the first time. Thus, there is no way to analyze or correlate your deposits with your withdrawals on the block chain.
Do I get same bitcoins back or other bitcoins?
First of all, you should realize that there is no “your” or “mine” bitcoins, nor are there “same” bitcoins. It is just numbers. Your coins are not “marked” in any way. The transaction you will receive from us will be just a number of coins transferred to stated address.
A link could be done just if you receive bitcoin from the address that you deposited bitcoins to. It is not about Bitcoin Fog. The coins you deposited will stay on the random address which we generated for you. Just when our main account is running low, we transfer the money from your deposit address to the main pool. In that way, you will get coins from the pool, thought your original money is still on the random deposited address, which is not connected to your payout. So there is no way to see where you have sent money to Bitcoin Fog or to random address, because bitcoin address is like any other.
Even if you waited enough for your money reached the pool, there is still no way to see that it was your original coins, since it was mixed with coins of other users.
Another story is the amount of your withdrawal. If you transfer 1.685 to us, and next day you withdraw almost same amount of bitcoins, those amounts will be visible in the block chain. Even if there were 15 people, who made same withdrawal that day, the link between your deposit and withdrawal will be obvious. Even though nobody else has access to our service and can prove that those bitcoins are yours, the link will be found anyway.
That’s why you should never deposit and withdraw the same amount. Divide your coins into different parts and only then send. Every time when you need to clean your coins, use new deposit address.
As we see, there was a lot similar services, but they all had many problems. Some had low security level or were not professional enough, therefore they had been easy to hack. Our service is the case for a long time. We have professional secure web application developers, who has 10-15 year long experience, because security is very important for our service. We aspire to be a mixing service that works without any silly problems, such as losing its private bitcoin keys due to poorly configured backups or hacker attacks.
Our service is run on a dedicated server, which we configured manually for this purpose. It is publically connected from the internet (not needed if using Tor). Bitcoin daemon is run on the other machine, where the website shuts down automatically if it senses any suspicious activity or the site is under attack. It is manually monitored and checked every day.
Because of security, the service operates only through Tor network. If you use out .onion address, you can be sure that your data is processed securely and only by our server. On the other side, we know that we will never be found by competent authority and this also makes us feel more secure. (Even if Tor network would be compromised, we have taken all the necessary precautions to still stay hidden.) This is better for you too. Even though Clearnet services may assure you they’re not cooperating with authorities, they are easily to find. We might as well say that we not only not cooperate with the authorities, but it will be very hard for them find us.
Is it safe to send bitcoins to anonymous service?
There always will be a problem of trust to our service, but we can assure you that the service will continue to work. A dozen of bitcoins is not worth all the work that had been done, time that had been taken and effort we put into building it and debugging it. When the time will pass, you’ll see that our service will bear changes and improvements, which someone who wanted to hit-and-run also would not do.
And again, we will not shut down our service because of the pressure of the authorities. And we still have to earn your trust. But we suggest you trying small amount to be sure in our honesty and then if you like, increase payments.
Do you keep logs?
We keep logs for 1 week for debugging and troubleshooting. After this time, they are automatically deleted. We are taking care of ALL logs. Even if bitcoin client we use is cleared every week, beginning with a fresh installation of only the block chain, and importing all the addresses we need at that point automatically. So if you’ve received bitcoins from us a month ago, even the address will not be on our server so far. If any service tells you that they don’t keep logs, they are most likely lying, because they will not be able to provide any support for the client who missed money, as they don’t have any history.
Fees and requirements:
The service takes from 1% to 3% (randomized for obscurity) fee on each deposit There are no other fees, no complex calculations based on the number of withdraws or similar. Minimum withdraw amount is 0.001 BTC. We do wait for 3 network confirmations on all deposits to prevent double-spending.
