$420 Billion In Zcash Tracked By Arkham — Is This The End Of The Privacy Coin’s Core Promise?

Arkham Intelligence, a company specializing in blockchain analysis, has discovered it can now identify the parties behind over half of all transactions on Zcash, a cryptocurrency known for its privacy features. They’ve linked $420 billion in Zcash transactions to specific people and organizations. This challenges Zcash’s primary goal of providing anonymous financial transactions.

A recent study published on May 21st by Arkham Intelligence doesn’t suggest Zcash’s security is flawed. The technology that enables Zcash’s private transactions – called zk-SNARKs – still works as intended. However, the research reveals a significant issue: most transactions on the Zcash network weren’t actually private in the first place, damaging the cryptocurrency’s reputation.

Why Most Zcash Is Already Visible

Zcash uses two kinds of addresses. The first, called t-addresses, are like standard Bitcoin addresses, meaning all transactions are publicly viewable on the blockchain. The second type, z-addresses, offer privacy by hiding the sender, receiver, and amount of the transaction within an encrypted system. According to research from Arkham, transactions sent from a z-address to another z-address are completely private and untraceable.

The report finds that most cryptocurrency exchanges, storage companies, and large investors generally use public addresses to meet legal requirements. This unintentionally makes a large portion of Zcash transactions publicly viewable on the blockchain, even though Zcash offers technology to keep transactions private. Specifically, when funds move between regular accounts and Zcash’s private transaction system through exchanges, these movements become visible, revealing the limits of even shielded transactions, according to analysis by Arkham.

According to new research, Arkham’s intelligence platform has identified the source of over half of all Zcash transactions. This is notable because Zcash is specifically built to hide transaction details, making it difficult to track.

The US Government’s Zcash Wallet

One of the most interesting findings in Arkham’s research involves the US Government. Arkham’s platform shows a US Government wallet holding ZEC, a privacy coin, that was seized from someone whose identity isn’t known. This is notable because the government is known for tracking financial activity, yet it’s now holding a cryptocurrency specifically designed to be untraceable.

The recent timing of Arkham’s research is particularly noteworthy given what’s happening in the crypto market. Arthur Hayes, the founder of BitMEX, has revealed he holds a significant amount of ZCash, predicting a long-term price of $10,000, which caused the coin’s value to jump over 40% in the last week. However, analyst Ali Martinez has pointed out potential signs of the coin becoming overbought. This all comes as the market is starting to re-evaluate ZCash and its potential.

This is a major moment for privacy coins, a small but growing part of the cryptocurrency world. When a blockchain analysis company links $420 billion worth of Zcash transactions to specific users, it’s not just a potential problem – it proves that the coin’s privacy features can be compromised.

This research brings up an important question for ZCash users who value financial privacy: if a large amount of ZCash activity is already trackable, what benefits are they actually getting from using it?
