currency

Currency refers to a universally accepted means of payment used for the exchange of goods and services. Traditional currency is issued by the government and has legal status, while cryptocurrency is a digital asset based on blockchain technology, such as Bitcoin and Ethereum. Cryptocurrency achieves transaction security and anonymity through decentralization and encryption technology, becoming an important component of the modern financial system. The main functions of currency include value storage, medium of exchange, and unit of account.

Gray Research Director: Ethereum is like a "small country," and the issuance of ETH determines the balance between network security and currency

Zach Pandl, the head of research at Grayscale, posted on the X platform comparing Ethereum to a "small country" and discussed the ETH issuance mechanism. He believes that Ethereum has only one core "government function": to protect property rights and value exchange within the system. Unlike traditional countries that provide public services through taxation, Ethereum primarily funds network security through "seigniorage," which is the issuance of new ETH.In this framework, the stakers responsible for maintaining network security are akin to a group providing public services, as they receive rewards through newly issued ETH. Therefore, Ethereum's staking mechanism and ETH issuance policy essentially constitute the network's fiscal and monetary policy. Zach Pandl pointed out that the Ethereum community needs to decide how much "new currency" should be used to cover network security costs. More security typically means stronger protection of property rights, but at the cost of a higher ETH issuance rate and potential other risks.For example, if network security increasingly relies on a few large staking service providers, there remains room for discussion about whether these providers can maintain the asset rights of all users completely neutrally. Pandl believes that, just as in traditional economies, no one knows the "optimal level" of government spending and currency issuance; the same applies to Ethereum. However, Ethereum has several key security thresholds, including: 1/3: an attacker reaching this ratio may affect finality; 1/2: affects blockchain fork choice; 2/3: can control the finality process. Some community members believe that the design of Ethereum's monetary and fiscal policy should consider the security trade-offs brought by these key ratios, while the current mechanism has not adequately incorporated these factors. However, the above analogy is not entirely accurate, as it does not yet involve other important factors such as the ETH burn mechanism, MEV, governance, etc.

The leak of French tax data affects nearly 678,000 people, which may exacerbate the risk of violent attacks against cryptocurrency holders

The French Minister of Finance confirmed that hackers breached the French Public Finance Directorate system at the end of June and stole personal and corporate taxpayer data. According to the platform FrenchBreaches, which tracks cyberattacks in France, this incident affected approximately 678,437 people, equivalent to about 1% of the French population, but the exact number is still under investigation and has not been finally confirmed.The leaked data reportedly includes sensitive information such as names, birth dates, home addresses, phone numbers, email addresses, tax identification information, and income data. Among them, nearly 27,000 individuals had tax incomes of at least 100,000 euros, 386 exceeded 1 million euros, and another 8 exceeded 10 million euros. Reports indicate that the database has been sold on the dark web market for thousands of euros. The attackers, calling themselves ZeroBytes, claimed they extracted the relevant records using an internal search tool, which was only discovered later when access was cut off.This incident has raised concerns in the cryptocurrency industry, as there has been a noticeable increase in "wrench attack" violent robbery incidents targeting cryptocurrency holders in France in recent years. If high-income individuals' addresses and contact information are leaked, it could provide criminals with a more precise target list.

A man was sentenced to 7 months in prison for defrauding a friend of $1,757 under the guise of a virtual currency airdrop project

A man in Anshun, Guizhou, used the name of a virtual currency airdrop project as a pretext to lure friends into investing with the bait of guaranteed high returns, ultimately crossing the legal red line. The People's Procuratorate of Pingba District, Anshun City, Guizhou Province, filed a public prosecution, and the court sentenced Zhao to seven months in prison for fraud, along with a fine of 5,000 yuan.Zhao had been paying attention to the field of virtual currency investment for many years and had long been posting investment insights and financial management tips on social media platforms. Zhang was also a virtual currency enthusiast, and the two met on a social platform due to their common interests, gradually becoming friends and frequently discussing investment strategies online. Through long-term communication, Zhao gained Zhang's trust with seemingly professional investment analysis. Subsequently, Zhao proposed a joint investment, to which Zhang agreed. However, after a period of investment, Zhang experienced significant losses and expressed his intention to stop further investments.On August 23, 2025, Zhao claimed that a certain app had launched an airdrop project (to promote a new project, encourage user participation, or reward loyal users, distributing native tokens of the project for free to eligible users), persuading Zhang to invest the remaining funds in his account into this project, promising a return of 100 to 200 U coins (virtual currency) within two days. Zhao also guaranteed that if there were any losses during this period, he would bear the responsibility. To further alleviate Zhang's concerns, Zhao claimed that all investment funds would be transferred to a public chain (the public address of the virtual currency). Believing Zhao, Zhang exchanged 1,757 dollars in his account for Ethereum and completed the transfer according to the wallet link provided by Zhao. In reality, the wallet corresponding to that link was a personal account registered using his girlfriend's identity information, not a public chain. The agreed time for the return of funds had passed, but Zhao had not fulfilled his promise. Zhang urged for repayment multiple times, but Zhao evaded responsibility with excuses such as sending the wrong link and needing time to track it down. On September 7 of the same year, Zhang reported the situation to the police after noticing something was wrong.On April 2 of this year, the Pingba District Procuratorate filed a public prosecution against Zhao for suspected fraud. The procuratorial agency believed that Zhao deceived others out of property by concealing the truth, with a significant amount involved, constituting the crime of fraud. Given that Zhao truthfully confessed to the criminal facts after being apprehended, showed signs of remorse, and had fully compensated the victim for their losses while voluntarily admitting guilt, he could be punished leniently according to the law.
