Bitcoin is often perceived as an anonymous payment network. But in reality, Bitcoin is probably the most transparent payment network in the world. At the same time, Bitcoin can provide acceptable levels of privacy when used correctly. Always remember that it is your responsibility to adopt good practices in order to protect your privacy. Bitcoin works with an unprecedented level of transparency that most people are not used to dealing with.

While Bitcoin can support strong privacy, many ways of using it are usually not very private. With proper understanding of the technology, bitcoin can indeed be used in a very private and anonymous way. As of most casual enthusiasts of bitcoin believe it is perfectly traceable; this is completely false.

Around most casual enthusiasts believed it is totally private; which is also false. There is some nuance — in certain situations bitcoin can be very private. But it is not simple to understand, and it takes some time and reading. This article was written in February A good way to read the article is to skip to the examples and then come back to read the core concepts. To save you reading the rest of the article, here is a quick summary of how normal bitcoin users can improve their privacy:.

Users interact with bitcoin through software which may leak information about them in various ways that damages their anonymity. Bitcoin records transactions on the block chain which is visible to all and so create the most serious damage to privacy. Bitcoins move between addresses ; sender addresses are known, receiver addresses are known, amounts are known. Only the identity of each address is not known see first image. The linkages between addresses made by transactions is often called the transaction graph.

Alone, this information can’t identify anyone because the addresses and transaction IDs are just random numbers. However, if any of the addresses in a transaction’s past or future can be tied to an actual identity, it might be possible to work from that point and deduce who may own all of the other addresses.

This identifying of an address might come from network analysis, surveillance, searching the web, or a variety of other methods. The encouraged practice of using a new address for every transaction is intended to make this attack more difficult.

The second image shows a simple example. An adversary runs both a money exchanger and a honeypot website meant to trap people. If someone uses their exchanger to buy bitcoins and then transacts the coins to the trap website, the block chain would show:. Say that the adversary knows that Mr. Doe’s bank account sent the government currency which were used to buy the coins, which were then transferred to address B.

The adversary also knows the trap website received coins on address C that were spent from address B. Together this is a very strong indication that address B is owned by Mr. Doe and that he sent money to the trap website. This assumption is not always correct because address B may have been an address held on behalf of Mr. Doe by a third party and the transaction to C may have privacy altcoins list unrelated, or the two transactions may actually involve a smart contract See Off-Chain Transactions which effectively teleports the coins off-chain to a completely different address somewhere on the blockchain.

You need to protect yourself from both forward attacks getting something that identifies you using coins that you got with methods that must remain secret, like the scammer example and reverse attacks getting something that must remain secret using coins that identify you, like the newspaper example.

On the other hand, here is an example of somebody using bitcoin to make a donation that is completely anonymous. As your full node wallet runs entirely over Toryour IP address is very well hidden. Tor also hides the fact that you’re using bitcoin at all. As the coins were obtained by mining they are entirely unlinked from any other information about you.

Since the transaction is a donation, there are no goods or services being sent to you, so you don’t have to reveal any delivery mail address. As the entire balance is sent, there is no change address going back that could later leak information. Since the hardware is destroyed there is no record remaining on any discarded hard drives that can later be.

The only way I can think of to attack this scheme is to be a global adversary that can exploit the known weaknessness of Tor. Bitcoin transactions are made up of inputs and outputs, of which there can be one or. Previously-created outputs can be used as inputs for later transactions. Such outputs are destroyed when spent and new unspent outputs are usually created to replace. This transaction has two inputs, worth 1 btc and 3 btc, and creates two outputs also worth 1 btc and 3 btc.

If you were to look at this on the blockchain, what would you assume is the meaning of this transaction? There are at least nine’ possible [1] interpretations:.

Many interpretations are possible just from such a simple transaction. Therefore it’s completely false to say that bitcoin transactions are always perfectly traceable, the reality is much more complicated. Privacy-relevant adversaries who analyze the blockchain usually rely on heuristics or idioms of use where certain assumptions are made about what is plausible. The analyst would then ignore or exclude some of these possibilities.

But those are only assumptions which can be wrong. Someone who wants better privacy they can intentionally break those assumptions which will completely fool an analyst. Units of the bitcoin currency are not watermarked within a transaction in other words they don’t have little serial numbers. For example the 1 btc input in that transaction may end up in the 1 btc output or part of the 3 btc output, or a mixture of. Transactions are many-to-many mappings, so in a very important sense it’s impossible to answer the question of where the 1 btc ended up.

This fungibility of bitcoin within one transaction is an important reason for the different possibility interpretations of the above transaction. When considering privacy you need to think about exactly who you’re hiding. You must examine how a hypothetical adversary could spy on you, what kind of information is most important to you and which technology you need to use to protect your privacy. The kind of behaviour needed to protect your privacy therefore depends on your threat model.

Newcomers to privacy often think that they can simply download some software and all their privacy concerns will be solved. This is not so.

Privacy requires a change in behaviour, however slight. For example, imagine if you had a perfectly private internet where who you’re communicating with and what you say are completely private. You could still use this to communicate with a social media website to write your real name, upload a selfie and talk about what you’re doing right. Anybody on the internet could view that information so your privacy would be ruined even though you were using perfectly private technology.

For details read the talk Opsec for Hackers by grugq. The talk is aimed mostly at political activists who need privacy from governments, but much the advice generally applies to all of us. Much of the time plausible deniability is not good enough because lots of spying methods only need to work on a statistical level e.

Multiple privacy leaks when combined together can be far more damaging to privacy than any single leak. Imagine if a receiver of a transaction is trying to deanonymize the sender. Each privacy leak would eliminate many candidates for who the sender is, two different privacy leaks would eliminate different candidates leaving far fewer candidates remaining.

See the diagram for a diagram of. This is why even leaks of a small amount of information should be avoided, as they can often completely ruin privacy when combined with other leaks. Going back to the example of the non-anonymous Chinese newspaper buyer, who was deanonymized because of a combination of visible transaction information and his forum signature donation address.

There are many many transactions on the blockchain which on their own don’t reveal anything about the transactor’s identity or spending habits. There are many donation addresses placed in forum signatures which also don’t reveal much about the owners identity or spending habits, because they are just random cryptographic information.

But together the two privacy leaks resulted in a trip to the reeducation camp. The method of data fusion is very important when understanding privacy in bitcoin and other situations.

Financial privacy is an essential element to fungibility in Bitcoin: if you can meaningfully distinguish one coin from another, then their fungibility is weak. If our fungibility is too weak in practice, then we cannot be decentralized: if someone important announces a list of stolen coins they won’t accept coins derived from, you must carefully privacy altcoins list coins you accept against that list and return the ones that fail.

Everyone gets stuck checking blacklists issued by various authorities because in that world we’d all not like to get stuck with bad coins. This adds friction and transactional costs and makes Bitcoin less valuable as a money. Financial privacy is an essential criteria for the efficient operation of a free market: if you run a business, you cannot effectively set prices if your suppliers and customers can see all your transactions against your.

You cannot compete effectively if your competition is tracking your sales. Individually your informational leverage is lost in your private dealings if you don’t have privacy over your accounts: if you pay your landlord in Bitcoin without enough privacy in place, your landlord will see when you’ve received a pay raise and can hit you up for more rent.

Financial privacy is essential for personal safety: if thieves can see your spending, income, and holdings, they can use that information to target and exploit you. Without privacy malicious parties have more ability to steal your identity, snatch your large purchases off your doorstep, or impersonate businesses you transact with towards you Financial privacy is essential for human dignity: no one wants the snotty barista at the coffee shop or their nosy neighbors commenting on their income or spending habits.

No one wants their baby-crazy in-laws asking why they’re buying contraception or sex toys. Your employer has no business knowing what church you donate to. Only in a perfectly enlightened discrimination free world where no one has undue authority over anyone else could we retain our dignity and make our lawful transactions freely without self-censorship if we don’t have privacy.

Most importantly, financial privacy isn’t incompatible with things like law enforcement or transparency. You can always keep records, be ordered or volunteer to provide them to whomever, have judges hold against your interest when you can’t produce records as is the case today.

Globally visible public records in finance are completely unheard-of. They are undesirable and arguably intolerable. The Bitcoin whitepaper made a promise of how we could get around the visibility of the ledger with pseudonymous addresses, but the ecosystem has broken that promise in a bunch of places and we ought to fix it. Bitcoin could have coded your name or IP address into every transaction.

It didn’t. The whitepaper even has a section on privacy. It’s incorrect to say that Bitcoin isn’t focused on privacy. Sufficient privacy is an essential prerequisite for a viable digital currency [2].

Bitcoin uses a block chain.
