Bitcoin de-Anonymity

Hey. Get some info that Bitcoin is not true anonymity. "Once you make the transaction ->it will be put into the blockchain with amount and addresses -> everyone can track your address current balance"
Where there any known cases deanonymization?

The possibility of community de-anonymizing attacks of /r/btc, sockpuppet revealing and the serious flaw in Bitcoin Cash's SLP tokens.

This post is an informative security briefing, done in the style of responsible disclosure to allow Bitcoin Cash users to consider their security.
It is expected if this security briefing manages to breach the heavily controlled censorship on /btc and actually gets posted there that the response will be "use Cashshuffle". This is not a good response for people who have whitecoins (i.e. legal ones) and will be mixing them with coins from unknown sources which can and most probably will lead to future problems with authorities. Not everybody has the pleasure of being official domiciled on St. Kitts & Nevis like Roger Ver or Andreas Brekken.
This is for all interested users and describes practices that have been done and attacks that could be prepared and is achievable not logged into reddit and just by referencing archived posts from archive.is [such as this one].(http://archive.is/OF419)
This post is being written to highlight a serious flaw and to raise the concern and security awareness of /btc users so they learn to value Satoshi Nakamoto's Wrightpaper and all it states about anonymity and privacy which are 2 different things. No doxxing or breaking of rules or T&C has been done and all information is information that has willingly been published by the authors in their quest for free useless valueless dumbass tokens.
SLP (Simple Ledger Protocol) is a basic token system for Bitcoin Cash created by Gabriel Cardona. This is one of the few developments that has happened on Bitcoin Cash that has not been copied from somewhere else, so is worth analysing to value their competence.
The idea is for very little fee you can create a token with a Ticker Symbol, a Description and a URI and can create any quantity of specific tokens.
As Bitcoin Cash is permissionless any user using memo.cash can create a token in less than a minute or any user with reasonable Javascript skills can create thousands of custom tokens with a simple script and very little cost.
Problem 1: Harassment by Token
Normally using services such as memo.cash you can block a user from being able to send you messages. A way to bypass this is simply to write your message as a token name, or a series of tokens you mint and sent to the user, or using programming mint into the possession of the user with just 1 TX.
And example would be a token sent to user Bob From Alice.
Alice creates a token with qty of 1 with ticker symbol name: "Bob you are a fucking asshole and I hate you". Ticker symbol names can have long lengths, but also additional messages could be in the description. Also a URL attached to the token which would probably be opened could include more text or even an insulting or offensive photo or image. In addition if the URL was a server Alice controlled it could include a unique ID such as http://alice.com/?frombobstoken which would allow the capturing of Bob's IP address by checking the logs so Alice would know it.
This harassment could be simple trolling, or it could verge on serious harassment in the case of example a ex-girlfriend. All you would need is the users SLP address, and you could follow the address as they moved other SLP tokens from their wallet.
A series of messages (unique tokens) can be created all with individual messages. This is different to most forms of internet-based harassment as users generally have their wallets on their cellphones, so the harassment literally gets to their pockets by way of a new token notification.
Problem 2: De-anonymizing Users
Users regularly try to get free SLP tokens by posting their addresses alongside their usernames. Common platforms are Telegram and forums, however it seems Roger Ver himself gets users to do this on reddit and even he is aware of the security implications but does not care.
An example would be this posting
It easy to see which users are posting "in-use" SLP addresses, and also the SLP addresses of the senders. Also sock puppets can be identified.
If I told you ErdoganTalk was MemoryDealers would it surprise you?
So now you could mint tokens with just a qty 1 token, you can mint thousands of custom tokens sending 1 to each reddit user with their reddit username as part of the token symbol to allow you to track these users throughout the blockchain.
Combine this with the flaw highlighted above (harassment etc..) and you can see that SLP tokens, Simple Ledger Protocol is really a dumbass protocol thought of by dumbass developers with little security thought or oversight.
The most important security is the security of your users and their well-being. Bitcoin Cash has clearly failed.
Thanks all for reading. Any questions reach out to me ( jim-btc ). Thanks :-)

Ready to CashShuffle and CashFusion Your Coins On-The-Go?

As many of you may already know, i’ve been working these past few months on a web-wallet called Nito Cash. The motivation is for greater Bitcoin adoption, by providing the simplest starting point for users to experience cryptocurrency. Notably, there are no seed phrases required to get started and you can easily sync across devices with the use of qr codes.
Perhaps overly ambition, Nito (as in Incognito) is meant to encourage use of the Bitcoin privacy protocols CashShuffle and CashFusion. 5 months later, I’m still working things out due to the challenges of bringing CashFusion to the web browser. However, I’m happy to say that CashShuffle is now available at https://app.nitojs.org.
NitoJS is an upcoming Bitcoin Cash Library and Software Development Kit (SDK) for helping developers bring their “unstoppable” dreams to reality. NitoJS will be a mobile-first library with compatibility on the server. The goal is to smooth out a path for developers to create fully decentralized (unstoppable) web-apps by leveraging the combination of the Bitcoin Cash blockchain and IPFS.
Won’t oversell anything as this is just a teaser, but I’ve been LIVE testing a CashFusion solution for the last few weeks and I’m expecting to have a public demo soonish'. Initially, I’ll offer a hosted solution, as that’s nearly complete (backend already done, frontend being worked on), followed by a self-hosted solution that you can run from your own pc. Both will enable the ability to CashShuffle and CashFusion your coins from ANY desktop or mobile web browsers (meaning it’s compatible with ANY and ALL wallets).
You can CashShuffle your coins on https://app.nitojs.org today. It’s buggy! You may have to reload a bit and there’s a RE-SYNC button on the settings page that you may have to use after depositing. Also, "RE-BUILD MY PURSE" WILL DELETE YOUR PRIVATE KEYS, so make sure your wallet is empty first. Otherwise, it’s all good!
Once I’ve cleaned up the code and UI a bit, I’ll make formal announcement on read.cash.
Cheers! 🍾🤣

A second generation of anonymization techniques has evolved that tries to eliminate the single point of failure while being deployable in the current Bitcoin system.1 These tech-niques can broadly be categorized into low-level anonymization techniques [3, 16, 17, 36] as well as high-level mixing protocols The article is largely based on ‘Research on Anonymization and De-anonymization in the Bitcoin System ‘, an ATR Defense Science & Technology Lab. paper by QingChun ShenTu and JianPing Yu from Bitbank Research Labs, published by Shenzhen University.

Data-Driven De-Anonymization in Bitcoin The anonymity and de-anonymity of blockchain and Bitcoin have always been a hot topic in blockchain related research. Since Bitcoin was created by Nakamoto in 2009, it has, to some extent, deviated from its currency attribute as a trading medium but instead turned into an object for financial investment and operations. Could Bitcoin Be De-Anonymised? As much as it claims to be so, the bitcoin network is not impenetrable. In fact, it could be easier than we think to get into the Bitcoin network and work through the system to find out where a transaction may have originated, thus destroying anonymity. If transactions were traced back through networks, it could ...
