pol

PoL (Proof of Liquidity) is a consensus mechanism designed to validate transactions through the provision of liquidity. Unlike traditional Proof of Work (PoW) or Proof of Stake (PoS), PoL rewards participants with block rewards for providing liquidity. This mechanism is commonly used in decentralized exchanges (DEX) or liquidity pools to incentivize users to provide liquidity, thereby enhancing market efficiency and stability. The advantage of PoL lies in its ability to encourage more liquidity providers to participate, strengthening market depth and trading liquidity.

Shanghai police in China have arrested a gang engaged in cross-border illegal operations of virtual currency through a self-built platform, involving 200 million yuan

The Public Security Bureau of Hongkou District, Shanghai, China, recently solved a case involving cross-border illegal settlement and illegal foreign exchange trading using virtual currency, arresting 9 criminal suspects and involving an amount of over 200 million yuan. The suspects, including a person named Li, established a technology company at the beginning of 2024 to seek illegal profits, building two platforms online: "Cross-Border Fund Exchange" and "Virtual Credit Card Issuance and Settlement." They solicited customers both online and offline, illegally conducting exchange and settlement services for virtual currency and cross-border funds, profiting through transaction fees, service fees, card issuance fees, withdrawal fees, and other means.Investigators stated, "The uniqueness of this case lies in the fact that the criminals developed two apps and publicly solicited customers on such a large scale, which has never been seen before. The platforms built in this case are themselves a closed-loop illegal financial service system, with all transactions settled internally on the platform. This mode of crime has a higher degree of scale, a longer chain, and is more deceptive." Reports indicate that on the "Cross-Border Fund Exchange" platform, the criminal gang collected customers' virtual currency overseas and exchanged it for foreign currency, forming a "fund pool," and then realized cross-border settlement through fabricated contracts, achieving the exchange and transfer of virtual currency to RMB. On the "Virtual Credit Card Issuance and Settlement" platform, the criminal gang "cooperated" with several overseas private banks to issue virtual credit cards to customers, who could use the card for consumption, but the repayment process had to be settled in virtual currency; the gang exchanged virtual currency for foreign currency overseas, relying on false cross-border settlements to complete clearing with overseas card merchants.

first_img The president of the Polish Olympic Committee was arrested on suspicion of cryptocurrency bribery

Polish Olympic Committee President Radosław Piszczek was arrested on Thursday, suspected of receiving kickbacks from the cryptocurrency platform Zondacrypto during the signing of a sponsorship agreement. Polish Sports Minister Jakub Rudnicki confirmed the arrest on the X platform, stating, "Such a person should not hold the position of President of the Polish Olympic Committee; Piszczek has brought shame to Polish sports." Interior Minister Marcin Kwiatkowski referred to him as "a symbol of extreme corruption plaguing the Olympic movement."According to the investigation, Piszczek facilitated the sponsorship agreement between the Polish Olympic Committee and Zondacrypto in October 2025, which promised cryptocurrency rewards to medalists of the 2026 Milan-Cortina Winter Olympics. The Polish government accused Zondacrypto of having ties to nationalist opposition groups, organized crime, and Russian intelligence agencies, estimating that the platform's collapse caused losses of about 350 million zlotys (approximately 80 million euros), affecting around 30,000 people. The Interior Minister described Zondacrypto as "essentially a Ponzi scheme."Media investigations also revealed that Piszczek received a Patek Philippe watch worth approximately 40,000 euros from Zondacrypto CEO Przemysław Kral, who claimed the watch was purchased out of his own pocket. Kral is currently cooperating with prosecutors in hopes of a reduced sentence. Zondacrypto was founded by Sylwester Sucheck in 2014, who went missing in 2022, with Kral taking over his position. The Polish prosecutors launched an investigation in April of this year, and most Polish sports federations subsequently called for Piszczek's resignation.

Hyperliquid Policy Center writes to the CFTC: Promoting perpetual contracts as a key focus of derivatives innovation in the United States

The Hyperliquid Policy Center stated on platform X that perpetual contracts should be at the core of the U.S. Commodity Futures Trading Commission (CFTC) innovation agenda. The agency submitted a statement regarding the first meeting of the CFTC Innovation Advisory Committee on August 20, pointing out that perpetual contracts are gradually expanding beyond the digital asset market to traditional asset classes such as stocks and commodities, and that demand for this product among U.S. market participants is rising.Perpetual contracts can meet the risk management needs of different market participants, making them particularly suitable for airlines hedging fuel costs, investment funds managing portfolio exposure, and AI developers addressing ongoing risks related to computing costs that do not have a clear expiration date. Compared to futures with fixed expiration dates, perpetual contracts do not require rolling over, and there are no expiration and delivery issues; they anchor contract prices to the underlying assets through periodic funding rates. Currently, on Hyperliquid, perpetual contracts deployed by third-party developers cover over 80 traditional commodity and stock markets, with a cumulative notional trading volume exceeding $500 billion.This year, the CFTC has taken several measures to promote the establishment of the perpetual contract market in the U.S. In May, the CFTC approved the first perpetual futures contract listed in the U.S. and issued a policy statement and continuous trading guidance regarding the listing of perpetual contracts; in June, the CFTC sought public opinion on extending perpetual contracts to energy commodities and further consulted on computing power derivatives.In addition, the Hyperliquid Policy Center believes that on-chain infrastructure can also promote the modernization of the U.S. derivatives market within the existing regulatory framework. Public blockchains can openly record markets, orders, and positions, continuously conduct margin assessments programmatically, and enable real-time collateral transfers, thereby reducing counterparty credit risk and settlement risk. The agency will continue to provide relevant research and technical documents to the CFTC Innovation Advisory Committee and committee staff, and promote the establishment of a pathway for U.S. market participants to compliantly access on-chain markets. The agency believes that perpetual contracts are one of the most representative financial innovations of the past decade and should be further developed in the U.S. market.

Bitget CFD Chief Analyst: On the eve of Jackson Hole, market focus shifts to inflation, long-term Treasury yields, and policy framework

Bitget CFD Chief Analyst Lewis Huang stated in a live broadcast that this week’s U.S. PCE data and the Jackson Hole Global Central Bank Annual Meeting will become the market focus. The market is not only concerned about whether the Federal Reserve will adjust interest rates but will also pay close attention to how it responds to inflation remaining above the 2% target, high long-term Treasury yields, and fiscal pressures.Lewis Huang pointed out that if the core PCE is higher than expected and the Federal Reserve signals a continuation of tightening or emphasizes anti-inflation measures, U.S. Treasury yields and the dollar may receive support, while interest rate-sensitive assets like gold and the Nasdaq 100 may come under pressure. Conversely, if inflation data cools and officials express a tendency to retain policy flexibility, the market may re-evaluate future easing space, benefiting gold, non-U.S. currencies, and growth-oriented stock indices. This PCE data is generally in line with expectations, and the market focus has shifted to the Jackson Hole Global Central Bank Annual Meeting.In addition, the situation in the Middle East and risks in the Strait of Hormuz may still push up oil prices and inflation expectations. Traders should closely observe the U.S. dollar index, U.S. 2-year and 10-year Treasury yields, and the correlation between gold and oil; after major data releases, it is advisable to wait for further market confirmation of direction to avoid using high leverage to chase the initial wave of trends.

first_img Coinbase's Chief Policy Officer rebuts the American Bankers Association: There is no evidence that stablecoin rewards lead to bank deposit outflows

According to CoinDesk, Coinbase Chief Policy Officer Faryar Shirzad wrote an article for CoinDesk rebutting the arguments made by the American Bankers Association (ABA) against the stablecoin reward provisions in the Clarity Act. ABA CEO Rob Nichols claimed that only minor wording changes were needed to strengthen the bill and warned that allowing stablecoin rewards would lead to a loss of deposits for community banks.Shirzad pointed out that Coinbase has been paying stablecoin rewards for USDC for over four years, while community bank deposits grew by 26% from June 2019 to March 2026, amounting to approximately $482 billion.Shirzad cited research from Charles River Associates and the Economic Advisory Council stating that there is no significant correlation between stablecoins and bank deposits. He emphasized that the credit card industry was built on reward mechanisms, and the banking industry itself relies on this model. The current text of the bill was reached after months of negotiations between Senators Tillis and Alsobrooks and bank representatives, clearly delineating the boundaries: prohibiting returns on idle funds but allowing compensation for real activities.Shirzad believes that the Clarity Act will grant banks the broadest statutory powers since the Gramm-Leach-Bliley Act of 1999, including custody, staking, lending, payments, clearing, and market-making, with community banks benefiting the most. He called on all parties to accept this compromise and work together to advance the bill.

first_img The end of the MiCA transition period poses a survival crisis for the Polish cryptocurrency industry

Morphic Financial Group founder and CEO Mateusz Kara wrote in CoinDesk that the MiCA transition period ended on July 1, and the Polish Ministry of Finance confirmed that existing virtual currency registrations no longer constitute a legal basis for VASP or CASP operations. Crypto services can only be provided by entities holding valid MiCA authorization. Poland previously had about 2,000 registered virtual asset service providers, but a domestic political deadlock prevented the establishment of a viable authorization pathway. Germany issued 57 licenses, France and the Netherlands each issued 26, while Greece, Hungary, Poland, and Romania collectively issued zero.Kara stated that Polish investors hold about 9.4 billion euros in digital assets, and the relocation of businesses will lead to the loss of compliance teams, capital, and investments, with rebuilding the ecosystem potentially taking years. The compliance costs for MiCA can reach up to 700,000 euros, and serious violations could face fines of several million euros, narrowing the space for small participants. However, he believes that MiCA will be beneficial for the European crypto industry in the long term, as accelerated consolidation will eliminate weak operators and create a safer market. The UK's FCA is also launching a similar system, but Poland may become a sales market for others rather than an active participant in European digital finance construction.

Analysis: Waller may release dovish signals at Jackson Hole, with US debt policy coordination becoming the market focus

The market is closely watching Federal Reserve Chairman Kevin Walsh's speech at the Jackson Hole annual meeting this Friday. As U.S. long-term Treasury yields continue to rise, the market generally expects Walsh to possibly release dovish signals to alleviate concerns about inflation and fiscal risks in the bond market.Mark Cabana, head of U.S. interest rate strategy at Bank of America, stated that the market has gradually lost sensitivity to Walsh's previous verbal statements about "fighting inflation," and investors currently hope to see a substantive policy path to address inflation. Meanwhile, Treasury Secretary Basant has recently increased the repurchase of long-term U.S. Treasuries and financed the government through the issuance of short-term bonds, indicating some divergence between the Treasury and the Federal Reserve in managing the bond market.The article points out that Basant's shift of financing pressure to the short end effectively bets U.S. fiscal costs on future interest rate declines. If Walsh can promote interest rate cuts by controlling inflation and boosting productivity, the short-term financing model is expected to reduce government interest expenses; however, if long-term rates remain high, U.S. fiscal pressure may further intensify.The market also anticipates that the Federal Reserve may make adjustments to liquidity management and balance sheet policies. Michael Cloherty, head of U.S. interest rate strategy at CIBC, believes that quantitative tightening could begin as early as the end of 2027, provided that regulatory rule changes can reduce banks' demand for reserves.Currently, the Federal Reserve still holds about $1.6 trillion in long-term U.S. Treasuries. Walsh's statements at Jackson Hole regarding long-term yields, inflation, and the path of balance sheet reduction may become an important signal for assessing the degree of future policy coordination between the Federal Reserve and the Treasury.
