Bitcoin Is Not Fully Private: Is That a Problem?

[Itz-prisigold]

Lots of people,  most especially newcomers think that Bitcoin is completely anonymous. When people hear about that for the first time, many assume that transactions cannot be traced and that nobody can see what you are doing. However,  this is not the case, Bitcoin is not fully private, and many users don’t realize this until they’ve already been using Bitcoin for a while.

Every Bitcoin transaction is recorded on a public blockchain,  that simply means that anyone can look it up. Although your real name or identity might not be tied to your wallet address,  but that does not mean that your activity is completely hidden from people,  so, Is the lack of full privacy a problem or is this just simply how Bitcoin is?

1. Bitcoin Is Pseudonymous,  Not Anonymous

With the use of Bitcoin, your identity is not directly revealed, but it is equally not completely concealed,  Instead of using people’s names, the system uses people’s wallet addresses. However, once an address is connected to a real person,  for example by using an exchange that does identity verification, all that person’s complete transaction history can be discovered.  So technically, Bitcoin is pseudonymous and not anonymous.

2. The Blockchain Is Completely Public

Bitcoin has many cool features.  One of those features is that it's completely transparent.  Anyone can simply look up Bitcoin's blockchain to see the many transactions that people carry out. This is actually one of the things that makes Bitcoin  trustworthy.  This transparency truly helps to prevent fraud,  double spending and every hidden manipulation of the monetary supply.  However,  here is the downside of this transparency.  All transaction histories will always be available.

3. Chain Analysis Is Getting More Powerful.

There are companies that specialize in studying blockchain transaction.

By looking at  transaction patterns and connections  between addresses,  which can be used to track  how coins move between wallets and sometimes even linked them to real world identities, most especially when exchanges with KYC are involved,  this is actually something that many users underestimate.

4. Privacy Usually Requires Extra Steps

If someone really cares about privacy when using Bitcoin.  The users are expected to take additional precautions.

This can be achieved with Bitcoin by employing the methods of:

- Avoid reusing addresses
-  Making sure none of your wallet are connected to your personal accounts

These methods improve privacy but not everyone knows about it.

5. Is This Actually A Problem?

Here is where the divide happens.

Some think that Bitcoin needs to have more privacy  features because of the increased criminal financial tracking.  Others think that transparency is a great feature so the system can be kept honest and verifiable.

I think the main problem is that people think Bitcoin is more private when in reality it is the exact opposite.

In the end,  Bitcoin is not fully transparent like a bank account,  but it is not completely private either,  Bitcoin just sits somewhere in the middle.

Just be sure to understand how it all works so that when you make a  transaction you do not have a false sense or  wrong assumption about your privacy.

True, and it's good for people to know so that they don't have a false sense of complete privacy, bitcoin was built be transparent, this way transactions can be followed on the Blockchain making it difficult for people to illegally move fund through bitcoin, I'm not all that bitcoin savvy to know whether there is a way to bypass this so as far as I'm concerned this feature are there to also make sure that bitcoin isn't used for fraudulent purposes making it trustworthy for a lot of people to use.

I don't think so, it's only addresses that send funds to your exchange account that can be connected to you and not all your transactions. Secondly, exchange wouldn't give anyone access to your exchange account talk more of your transactions only if you are a suspect and the government knows you are using that exchange.

This is why when you want to send funds connect your wallet to Tor and sort out your wallet address so that you should only use the ones, you want to be connected to an exchange to send money to that exchange. It's also good to use coin control when sending funds out from your wallet.

- Avoid reusing addresses

In a forum like this, it's difficult not to reuse receiving addresses.

[Shadiq]

Who says you need an exchange (with KYC) to use Bitcoin? You can use Bitcoin without an exchange and Bitcoin encourages you not to use an exchange. Because Bitcoin wants to keep you decentralized.

In the case of blockchain transactions, do not exchange wallet addresses with someone you know or change an address if you feel it is risky or use a wallet only once. Creating a decentralized wallet is completely free and easy.

It is not difficult to be anonymous with Bitcoin, Bitcoin is still anonymous and can keep your identity completely hidden. You just have to educate yourself about privacy. By using exchanges, we are trying to centralize Bitcoin and put privacy at risk. This is not Bitcoin's fault. If you use an address only once and also transact behind the scenes through the blockchain, it is not possible for anyone to know your identity unless you reveal it.

If you avoid platforms that require KYC to use, your transactions could remain private. There are also privacy tools like mixers and CoinJoin Wallets that could also improve the privacy of Bitcoin users. However the US governments also investing in research and development of advanced blockchain tracing tools to aid investigators track movement of funds. Infact, Bitcoin is the wrong currency to use for fraudulent transactions. Cash fiat remains the ideal currency for criminal transactions.

Before you could dive into Bitcoin in full, try to first have an understanding of what blockchain is and how it is an open distributed ledger, know how we could make use of this decentralized network to secure our financial freedom have our privacy and the security needed, all these are the most important aspects of Bitcoin which everyone is expected to know, no one is in control of Bitcoin or the network and that is why it is a decentralized digital currency with grant everyone the freedom and access to control their financial economy themselves.

Your thread is misleading. Bitcoin is fully anonymous and private what you are pointing out as said flaws of privacy on the network are just simply a function of transparency which is part of the features of the network itself. In context the idea is basically you can see but you can't really identify.

There are millions of addresses out there and you cannot tell who spends and who receives except you have information from outside the Blockchain. You should look properly on privacy and transparency both have their contexts.

I think there might be a little confusion here,  probably between anonymity and pseudonymity. Bitcoin addresses do not have names attached to them,  which is correct, but that does not make the system completely anonymous, Bitcoin actually only offers pseudonymity,  because every transaction and every address is visible forever on the blockchain.

You are also correct that you usually can not identify the person behind an address just from the blockchain but however,  once an address is connected to an actual identity through something off the blockchain,  like a KYC exchange, a public donation address, or a merchant payment,  the transaction history connected to that address can be analyzed.

So, yes,  the transparency of the blockchain is definitely a feature of the network no doubt about that,  Bitcoin offers some privacy, but it is not completely private,  that is the reason why many people describe Bitcoin as pseudonymous, not fully anonymous.

This can be achieved with Bitcoin by employing the methods of:

- Avoid reusing addresses

How can you avoid reusing addresses?

The current BIP32 standard used by most wallets often generate new address for every deposit request, though it it doesn't help in much ways to protect privacy since the transactions can still be traced to one owner.

Are you aware that an input can contain multiple UTXO from different addresses when spending Bitcoin, except the sender specify, from which UTXO not to spend from using coin control, if you don't specify which UTXO to spend from, the input includes enough UTXO needed for the transaction into one when spending, and it can be traced and linked to each other bridging the privacy of reusing addresses.

You either don't use CEX or use DEX if you don't wallet connecting to your personal account (identity), or face to face P2P which is also breaking privacy, even while using CEX, i believe my identity is hidden behind my address.

Honestly I learnt about Bitcoin not being private and anonymous long after I have used Bitcoin for years. Earlier on I thought Bitcoin completely shield one from the authorities but developments in Bitcoin and my presence in this forum have opened my eyes to know better. Depending on many reasons, it is better to preserve the privacy of your Bitcoin which is exactly what it was designed for, to do this, you can pass every large quantity you are holding through a mixer to ensure there will be no issue for you in the future.

Bitcoin have been built on a solid blockchain and there's no way this project won't skyrocket to the moon. Investor's that are wise wouldn't even be settling for average outcome rather they will buckled up and bend their direction to ward's making huge profits.  Bitcoin can be seen as private because everyone can easily have access to it the moment they have a little clue about cryptocurrency. Trustworthy, it will become a project that saved lives.

OP, you sound as if you know a lot about Bitcoin while you don't.
Bitcoin is fully anonymous and private. The blockchain does not store any personal information, it only contains information of the transaction (address of the sender and the receiver).

You expose your privacy when you make use of centralized exchanges instead of bitcoin wallet to make transaction. Bitcoin ATM also limit privacy. If you want to maintain full privacy, download  a bitcoin wallet, make use of it for all your transactions.

Bitcoin transaction is traceable to personal info under certain conditions. Namely;

Casino
Centralized exchanges
Bitcoin ATM
Bitcoin POS terminal
Investing through an institution

Any platform that demands KYC in general.

Bitcoin as a whole promotes privacy, but the transactions are not private. Since everybody can see the transaction on the blockchain but nobody can tell who made the transactions (except when you've revealed yourself one way or the other), that makes you private even though your transactions are public. That is one of the many geniuses of Bitcoin. Unlike the banking system, where a transaction is private, but the person is not. Once anybody sees the account name, they know the person or company that made the transaction.

Some think that Bitcoin needs to have more privacy  features because of the increased criminal financial tracking.  

That is because they don't know what they are talking about, but they just want to talk. If Bitcoin transactions were private, it would be a scam haven. When nobody knows your address and nobody can see the transactions you make, how can a person prove you've not done a transaction if you say you have? It would attract all sorts of criminal activities and would drive away the actual regular users. Which will make governments ban it completely.

Quite the opposite, you’re the one acting like an expert while repeating what the OP has already said. Did you read the OP at all before posting? Bitcoin is not private neither is it anonymous as all transactions are public on the blockchain. If you want privacy, you should use privacy coins.

Do you actually know the meaning of anonymous and private? I don't think you do. If not How could say Bitcoin is fully anonymous and private when every transactions are recorded on a public ledger. Perhaps you should say Bitcoin is pseudonymous, instead of saying Bitcoin is anonymous and private. Something is anonymous when the real identity of that thing is completely unknown, and remain unknown. bitcoin is not fully anonymous because in one way or the other you can still trace who owns a particular Bitcoin address.
Someone don't necessarily need to make use of exchanges, before the person privacy can be expose, but exchange is one of the common way someone can expose his or her real identity.

In context the idea is basically you can see but you can't really identify.

I didn’t find anything misleading on OP’s post actually rather I am in support of his fact that bitcoin is not anonymous nor private rather the right word to use is pseudonymous because the blockchain is a public ledger that actually stores all transactions permanently. If we are talking about total anonymous and privacy we talk of coins like monero which actually has transactions hidden and not public.

As for bitcoin, you can actually stay anonymous by trying out some certain things which is never to have any of your address linked to any address, this why the first advice bitcoiners seeking anonymity get is they should never reuse their address and just go for one address for one transactions.

There are millions of addresses out there and you cannot tell who spends and who receives except you have information from outside the Blockchain. You should look properly on privacy and transparency both have their contexts.

You can link up addresses together if you’re not using your own full node or using any IP address hider like TOR because the public node you connect to will know all this addresses belongs to one person, just that it cannot be linked to your public face without it linked to any KYC platform.

[nelson4lov]

I don't think Satoshi created Bitcoin to be private. He created it to be publicly verifiable with all transactions transactions. However, bitcoin in itself is pseudonymous so we still have a bit of privacy as long as we use our addresses in a way that doesn't link back to us. I don't think we need to overcomplicate what bitcoin offers. Anybody that needs fully private transactions can get it in other privacy-centric cryptos.

You know, both those term could be really confusing to some and in most cases, you find it being a problem due to individual objectivism but,

Privacy isn’t encroached upon when it’s not tied to a human persona. That you initiated a transaction and it’s being recorded on the blockchain with none of it being tied to you as a person simply means, you still remain private and exercise a great deal of anonymity on your dealings. All that is still very okay and works to maintain the integrity of Bitcoin and it’s network.

[Dr.Bitcoin_Strange]

@OP, I couldn't agree more with Mia Chloe opinion, reading your thread, I was just trying to capture what you are insinuating but at the end, I can't agree less with your idea, your bitcoin transaction is completely private as long as you are using a decentralized platform that doesn't ask for your personal information when ever you make a bitcoin transaction from your wallet or ask for KYC before you use it.

Even though your transaction history and activities are recorded on the blockchain which is for transparency reason and that happens to be the feature of bitcoin, such transaction histories on the blockchain doesn't still reveals identity to anyone, meaning that you are private with your bitcoin.
