Arkham Announces 'De-anonymization' of ZCash. Which Transactions Are Being Tracked

Özet

Analytics platform Arkham Intelligence has announced it has begun "de-anonymizing" transactions of the privacy-focused cryptocurrency Zcash (ZEC). Arkham claims to have labeled over half (53%) of all ZEC transactions, including both private (shielded) and public ones, and has linked $420 billion worth of ZEC to specific individuals and entities. Its monitoring tools provide alerts for large transactions and use AI for analysis. As an example, Arkham highlighted that the U.S. government holds $1.26 million in ZEC, confiscated from AlphaBay founder Alexander Cazes eight years ago. Zcash creator Zooko Wilcox responded by stating the announcement is not true de-anonymization, as ZEC users themselves choose whether to make their transactions visible on such a dashboard. The news comes amid a significant price surge for ZEC, which has increased nearly tenfold since the start of the year. Wilcox admitted he does not know the reason for the price increase but dismissed theories of a "coordinated pump" as cynical propaganda. Zcash supporters argue that Arkham's labeling is primarily based on data from the public portion of the network, though Arkham asserts it used methods to correlate some activity from the private pool as well.

Analytics platform Arkham has announced that it has started 'de-anonymizing' transactions in the Zcash cryptocurrency. This coin is known for allowing users to choose between private or public transaction processing.

Arkham claims to have labeled more than half (53%) of the transactions in the Zcash network, both shielded and open. Analysts have linked $420 billion in ZEC to specific individuals and organizations. Arkham's features for monitoring Zcash activity include the ability to receive notifications about large transactions, as well as analyze operations using artificial intelligence.

As an example of Zcash monitoring, Arkham pointed out that eight years ago, the US government confiscated $737,000 in ZEC from AlphaBay founder Alexander Cazes, which has appreciated in value over the years. The US government's balance now holds $1.26 million in ZEC.

Zcash creator Zooko Wilcox stated that this is not de-anonymization in the full sense, as ZEC users themselves decide whether their operations will be visible.

"The Arkham headline makes it sound like they can 'de-anonymize' Zcash owners. But in reality, when you use Zcash, you choose for yourself whether one of your wallets will be displayed on their dashboard or not," Wilcox wrote.

This fall, after almost five years of dormancy, the price of ZEC has increased nearly tenfold since the beginning of the year. Such a sharp spike has caused a lively reaction in the crypto community, dividing it into two camps: some believe the growth is a natural revaluation of the project's fundamental characteristics, while others see it as the result of a large-scale and coordinated promotional campaign.

At the end of October, Wilcox admitted that he did not know why ZEC was rising so much in price or if it would fall back. "But here's what I do know: the talk about this being a 'coordinated pump' is just more propaganda from people who can't believe in something good and genuine," the ZEC founder wrote.

Zcash supporters on social media also claim that the main part of Arkham's labeling is based on data from the open part of the network. The company itself assures that it used methods to correlate some activity from the private pool as well.

As of 12:40 Moscow time, Zcash is trading around $410. Over the past 24 hours, the coin has appreciated by 4.5%, and over the year by 543%.

Suspected 4th Coldcard attack wave sweeps 389 Bitcoin: Galaxy’s Thorn

Coldcard hardware wallet users are facing a new wave of coordinated attacks targeting a firmware flaw, with researcher Alex Thorn flagging 218 recent transactions moving approximately 389 Bitcoin from potentially impacted addresses. The attack pattern shows a high rate of transactions targeting unique victim addresses, differing from previous waves. The vulnerability, which causes affected devices to generate weaker wallet seeds, is estimated to have impacted over 1,100 wallets, leading to around $90 million in Bitcoin stolen. Thorn advises affected users who control their keys may attempt to move funds with a higher-fee transaction before the attacker's transactions are confirmed.

Bitcoin Miners Are Waving the White Flag, But Their Stocks Are Soaring

Bitcoin miners are capitulating as evidenced by a sustained drop in network hash rate and a record-steep 19.9% decline in mining difficulty, signaling the shuttering of unprofitable machines. However, in a significant divergence from historical patterns, the stocks of publicly traded mining companies have soared, with one major player gaining over 430% in the past year, even as BTC's price fell roughly 46%. This surge is largely attributed to these companies pivoting toward the more lucrative AI narrative. Simultaneously, miners face a structural squeeze. Daily block reward revenue in BTC terms has hit a new all-time low following the latest halving, with current dollar-denominated daily revenue around $30 million compared to a longer-term average of ~$40 million. Fee revenue remains negligible, covering less than one block's subsidy over a 28-day average and accounting for only about ten minutes of the network's daily security budget. This capitulation cycle is unique: miner stress and crypto price weakness have decoupled due to alternative revenue streams (AI), while the long-term reliance on increasing bitcoin prices to offset shrinking subsidies continues, with fee income still far from filling the impending gap.

Will the Fed Definitely Raise Interest Rates in September? How Will Crypto and U.S. Stocks Withstand the Pressure?

The market's expectation for a September Fed rate hike surged dramatically in early August, jumping from under 50% to over 80% within a week. This shift followed a contentious July FOMC meeting, where a 9-3 vote to hold rates revealed growing dissent from hawkish members advocating for an immediate hike to combat persistent inflation. The primary catalyst for this repricing is rising oil prices, driven by renewed geopolitical tensions around the Strait of Hormuz, which threaten global supply. Energy costs directly influence inflation metrics, making the upcoming July CPI report (due August 12th) a critical data point. If it shows inflation reaccelerating, the probability of a September hike will solidify. For Bitcoin and crypto assets, this is typically bearish news. Bitcoin continues to behave as a high-beta, liquidity-sensitive risk asset. A rate hike raises the opportunity cost of holding non-yielding assets and could drive capital toward money markets, pressuring crypto prices in the short term. However, historical patterns suggest that if a hike is perceived as the end of a tightening cycle rather than the start, any negative price impact may be brief. U.S. stocks, particularly crypto-linked equities like Coinbase and growth-oriented tech stocks, are also vulnerable. Higher rates increase discount rates in valuation models, putting pressure on high-multiple companies. This coincides with a pivotal tech earnings season where investor focus has shifted from massive AI capital expenditure to tangible revenue and cash flow generation. Companies with negative cash flow and weak growth narratives could face heightened volatility if borrowing costs rise in September. In summary, a September Fed hike has evolved into a mainstream market scenario. Key factors to watch are oil prices, the July CPI report, and Fed communications, which will determine the final decision and its impact on volatile crypto and equity markets.

A 'Overlooked' Market Event: Joint US-Japan-South Korea Intervention, Rare US Treasury Involvement, and Bessent's Quiet 'Market Rescue'?

Summary: The United States, Japan, and South Korea executed their largest coordinated foreign exchange intervention in nearly 30 years. The action targeted depreciation pressure on the Japanese yen and South Korean won. This move is seen as a significant effort by the US to stabilize the financial markets of its key allies and prevent the spillover of risks. Key details: * Japan reportedly intervened on July 30 using approximately 8.45 trillion yen (about $52.8 billion). South Korean authorities also intervened that day, selling dollars to support the won. * Notably, the US Treasury Department intervened directly in yen markets for the first time in roughly 30 years. The New York Fed, reportedly acting on behalf of the Treasury, sold euros to buy yen via Goldman Sachs and Morgan Stanley on July 31. Analysts view the use of the euro-yen pair as a way to alleviate yen pressure without adding selling pressure to the US dollar. * Prior to the action, the New York Fed conducted "rate checks" on both USD/JPY and EUR/JPY, a newer signaling tool that falls between verbal and physical intervention. The intervention is interpreted as going beyond traditional currency stabilization. Analysts, such as Michael Hartnett of Bank of America, suggest it resembles a "Price Keeping Operation" for the AI era. The core US objectives are perceived to be: 1. Preventing rapid yen depreciation from triggering a sharp rise in Japanese government bond yields. 2. Containing financial stress from spreading across Asian markets like South Korea and Japan. 3. Reducing the risk of disorderly capital flows impacting the US bond market. This coordinated action underscores the importance of Japan and South Korea as critical partners in the US semiconductor and AI supply chain. Stabilizing their financial markets is seen as vital to mitigating risks to the broader tech industry and the US market itself. The intervention coincides with market pressures, including the KOSDAQ index hitting a low since October 2022. While seen as a move to control volatility, some analysts caution it may not fundamentally reverse existing market trends.

Will the Federal Reserve Definitely Raise Interest Rates in September? How Will Cryptocurrencies and US Stocks Bear the Pressure?

In early August 2024, market expectations for a September Federal Reserve rate hike surged dramatically, from below 50% to over 80%, driven by renewed inflation concerns. This shift followed a contentious July FOMC meeting where a 9-3 vote to hold rates revealed a growing hawkish faction advocating for an immediate hike, citing prolonged above-target inflation. The key catalyst is escalating conflict near the Strait of Hormuz, which has pushed oil prices up approximately 20% in July, threatening to reignite inflation. The next critical data point is the July CPI report on August 12th; a hot reading could solidify hike expectations. For crypto assets, particularly Bitcoin, this represents near-term pressure. Bitcoin continues to exhibit high-beta, risk-on characteristics, making it sensitive to tightening liquidity and higher opportunity costs. However, historical precedent suggests that if a hike is perceived as the cycle's end rather than its start, the negative impact may be brief, with markets quickly pivoting to anticipate future rate cuts. U.S. stocks, especially crypto-linked equities like Coinbase and high-valuation tech stocks, face amplified volatility. Higher rates increase discount rates in valuation models, pressuring growth stocks. This coincides with a pivotal tech earnings season where investor focus has shifted from massive AI capital expenditures to demonstrable revenue and cash flow generation. Companies with negative cash flows and weak growth narratives could see severe pressure if a September hike materializes, as financing costs would rise. Key indicators to watch include oil prices, upcoming inflation data, and Fed commentary at events like the Jackson Hole symposium.
