Yesterday, an investor filed a lawsuit in Delaware Chancery Court, accusing Coinbase's board members, including Chairman and CEO Brian Armstrong, of selling $2.9 billion in stock during the company's public listing two years ago. The lawsuit claims that the board later revealed "material, negative information" that severely impacted market optimism.
In a separate legal issue, another lawsuit was filed in San Francisco on the same day, alleging that Coinbase violated Illinois' biometric privacy law. The complaint asserts that the company collected customer data without obtaining proper consent beforehand.
As Coinbase faces these dual legal challenges, it seems the company is in for a tumultuous ride. It remains to be seen whether these lawsuits are simply part of a fear, uncertainty, and doubt (FUD) storm brewing on the horizon, or if they represent more substantial concerns for the cryptocurrency giant. 
Ameen Soleimani, one of the first contributors to the scandalous Tornado Cash crypto mixer, has announced the launch of a new mixing service called Primacy Pools, which is based on the TC code.
Now, every hacker and criminal will have a chance to demonstrate that they are not engaging in any malicious activity (but not for sure). What is clear is that honest users will be able to prove that they have not committed fraud and are therefore legitimately using the privacy-enhancing service.
Predictably, the new service uses zero-knowledge proof, which is the main trend of 2023. It is a protocol that confirms information without disclosing it.
Your move, SEC! 
Celsius Customer Data Exposed Sparking Privacy Concerns
As Celsius continues to deal with the aftermath of its bankruptcy, the United States Bankruptcy Court Southern District of New York disclosed data relating to thousands of the service’s customers, including names, amounts, types, descriptions, and timing of transactions on the platform. Coinbase-Backed Lawsuit Fights Tornado Cash Sanctions
Coinbase has joined six plaintiffs in a legal challenge against the US government's sanctions on Tornado Cash, a privacy-focused cryptocurrency mixer. The parties argue that the sanctions imposed by the Office of Foreign Assets Control (OFAC) are a violation of their Constitutional rights and are seeking to reopen Tornado Cash for all US-based citizens. 
What is zero-knowledge proof?
Zero-Knowledge Proof is a technology that allows you to verify the veracity of a piece of information without disclosing the information itself. Such technology is gradually gaining importance as a means of enhancing security and privacy in blockchain, cryptocurrencies, and DeFi. 
Arkham Intelligence has developed an app that uses a Twitter handle to search for anyone's activity across various blockchains, including Ethereum, Polygon, and BNB Chain.
The app can:
find wallet addresses that the user has interacted with;
filter the user's recent transactions;
visualize their actions on the blockchain.
Anyone who wants to join this impressive initiative can sign up for the waitlist.
The first entities on the waitlist are probably the IRS and the FRS. 
The Dubai Virtual Assets Regulatory Authority (VARA) has changed its virtual asset circulation rules.
A significant change was the prohibition on so-called privacy coins such as ZCash and Monero.
Organizations operating within the local jurisdiction are also prohibited from issuing and promoting this type of cryptocurrency.
Well, you can't really blame a major cryptocurrency hub like Dubai for that. They provide transparency and demand it in return.
