There is this thread (https://bitcointalk.org/index.php?topic=2680267.0), which is also full of statements, but without any proof or link. Already the OP choose a name, which make the content doubtful, and the headline doesn't count at all for scientific proofs. It is good to start a discussion, but luckily this post remained unanswered.
This thread (https://bitcointalk.org/index.php?topic=288545.0) has many links to SHA256 and NSA, but it doesn't become obvious, if there is a backdoor or not. It also looks more like speculation.

In the first topic, the guy was just giving his own opinion. It's a conspiracy theory that is around for a long time now. Maybe a friend of Alex Jones. You can read conspiracies about anything on the web. As for the document the member was talking about, this is the report from 1996.

In the second topic, i would say nobody here has enough knowledge to give us a proof. I don't say it's impossible Big Brothers NSA has broken already bitcoin, but if a single proof existed, it would be public all over the web

Technically  TumbleBit can work like, it makes a round in every hour. These transactions are leaving specific clues on the blockchain, so someone might can identify which addresses are participating in a round, but no way to tell which addresses sent to which one.

Bitcoin is often used as an anonymous currency because bitcoin can be sent and accepted without providing any personal identity information. However, bitcoin itself is not completely anonymous in most cases. Bitcoin transactions are never truly anonymous and can be searched through the block chain!

There are many situations where the weak anonymity of Bitcoin is far preferable to other payment means, such as PayPal, or CC.

A partial list would include such things as political donations and porn site payments. How many things can you think of, where people spend, but where there are issues, problems or outright risks with credit cards?

Satoshi did not develop Bitcoin with 100% anonymity for a reason :

1. 100% Anonymity will give 100% protection to scammers/thieves/hackers and criminals.

2. 100% Anonymity will get 100% push back from governments. They would have banned it long ago, if Bitcoin had 100% anonymity.

Satoshi gave it Pseudo-anonymity to place it in the same category as fiat Cash. It is after all a alternative Cash system.  Cool

The idea that bitcoin is fully anonymous is a myth. Government with the right resources can track down owners of bitcoin. Look at how Coinbase were just forced to hand over documents of their customers. I'd say bitcoin is semi anonymous or anonymous to anybody not looking for you

When it comes to bitcoin, we talk about anonymous transactions, bitcoins are not anonymous. Bitcoin hides the identity of the seller and buys only leaving the number of transactions and it's manifest

I may be wrong, but I believe that it's simply too late to improve bitcoin's privacy/anonymity at a protocol level... if segwit was controversial, then imagine adding that thing. A lot of big companies and exchanges are going to buy miners in order to not give hashrate to approve that update, because big companies im sure are not going to like anonymity at the protocol level since all of them are forced into KYC deals. Imagine people sending transactions into Coinbase in a totally obscured way.. im sure it's not going to be easy to get it done, we'll see a lot of opposition. I would like it to be optional, so if you want you could either do a clean transaction or obscure the amount + use a CoinJoin type of solution to obfuscate ins and outs.

In fact, for a long time already there are services that make it very easy to analyze the blockchain. bitcoin is not anonymous. This is a fact known to many people.

This was a very interesting thread and as a lay person, aka normie aka non-techie, user of bitcoin, complete anonymity and privacy is low on my list. Security is top. But after reading, I see that all three are intertwined. There are bitcoin forks looking into more privacy. Bitcoin as is was envisioned to be pseudo-anonymous. Having a public ledger is necessary and thus, if by anonymity you mean completely obfuscated and private transactions, there are other coins that try to fill that need as an alternative to bitcoin. There were a couple mentioned. What is interesting for example is that malware and ransoware makers are moving from bitcoin to monero. That's indicative right away about privacy/anonymity of bitcoin versus alts.

So yeah i've read some things about confidentional transactions to enhance privacy in Bitcoin, but i don't really know what it means.

Will Bitcoin enable anonymous transactions&addresses? So you could have an address and nobody knows how much Bitcoins you have/nobody can see your transactions/worth of transactions...?

What level of privacy/anonymity will these implementations provide?
The real question is why ?, the whole ida behiend using the blockchain netowrk is that every transactions is veriefied and made public, it is how the system works, while the transaction information are public, the users are still anonymous because they are hidden behiend their bitcoin address and not their personal information, i don't think that anonymous addreess and transactions would exist because they would still need to be verified by miners.

I think that I know the reason why the blockchain network is not totally anonymous. People who use bitcoin are always hiding behind their bitcoin address and also their personal information, so no one can know you exactly your location or what is your name or specific details like that, but they know how much do you have in your address and they can see your transactions. I don't think it will be right if you also hidden this thing, so then you can't even make any proof that you are already sending/receiving bitcoins.

You know, even if you did use a privacy/anonymous coin, the premise of the "system" you mention doesn't change. Transaction with anonymous coins can still be proven and verified, if coins were sent or received - only that in most cases, this information is privileged to parties to the transaction. So yeah, you couldn't look up the balance unless you were given access, but the anonymity features don't remove auditability, they merely restrict it.

No, cash is several times more anonymous than bitcoin, or any other cryptocurrency whatsoever. With cryptocurrencies, there's digital traces, no matter what you want to do about it, there will be traces left, this decreases anonymity, because systems can't be perfect, this anonymity can eventually be exploited.

With cash, due it's simplicity, you get simply a piece of paper. These pieces of paper run in the wild with no traces. It does not get more anonymous than that, which is why governments are going to ban cash, and then it's when I predict anonymity features will be pushed into Bitcoin, or else Monero will get an huge pump, since everyone using cash will most likely use Monero.
