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.

Chinese-American crypto investor Harry Yeh fell from a 30-story building in Paraguay, and the police are investigating the cause of death

According to La Tribuna, the body of a Chinese man was found outside the Jade Park high-rise apartment in the Trinidad district of Asunción, Paraguay. Preliminary identification confirmed the identity as Harry Chun Tak Yeh, the founder and managing partner of Quantum Fintech Group. The police stated that he is suspected to have fallen from the 30th floor of the building, and his body was found completely naked and covered with a black plastic bag. Investigators found the apartment door on the 30th floor ajar, with the interior in disarray, and confirmed that he also owned another apartment on the 27th floor of the same building. Criminal technicians have collected evidence outside the building and from both apartments, and relevant physical evidence has been handed over to the prosecution. The prosecution is currently investigating multiple possibilities, including accident, suspected suicide, and homicide, while the judicial department will determine the specific cause of death and the circumstances through an autopsy.It is reported that Chinese-American cryptocurrency investor Harry Yeh entered the Bitcoin market in 2013 when the BTC trading price was $60. He launched his first fund with $250,000, and his investment network claims to manage over $2.4 billion in assets, closely linked with Fantom, Tomb Finance, Lif3, ZooCoin, L3 USD, and L3 Reserve.

Trump's eldest son is associated with Kalshi and Polymarket, raising concerns about conflicts of interest and information advantages

According to Fortune, the Trump family is accelerating its entry into the prediction market space, with the Trump Media Technology Group developing a prediction market platform called TruthPredict, allowing users to trade prediction contracts related to significant events. The company has also launched the Truth API, providing Wall Street with quick data access to Truth Social content. Additionally, Donald Trump Jr., the eldest son of Trump, currently serves as a strategic advisor to Kalshi, and his venture capital firm 1789 Capital has invested in competitor Polymarket and joined the advisory board of Polymarket. This means the Trump family is simultaneously associated with the two major prediction market platforms, while the Trump Media Group is building its own prediction market business.Although there is currently no public evidence showing that Donald Trump Jr. or the Trump family is trading on government insider information, the potential conflicts of interest arising from the intertwining of presidential public information, market trading, and family business interests are drawing external attention. Federal agencies are still investigating whether former White House teleprompter operator Gabriel Perez used advance knowledge of Trump's speech content to trade in related markets on Kalshi. The team of Donald Trump Jr. and the Trump Media Technology Group have yet to formally respond to requests for comments regarding insider trading related to the prediction market.

U.S. employment unexpectedly shrank in July, posing a policy challenge for the Federal Reserve, as market expectations for interest rate hikes quickly declined

In July, the United States unexpectedly lost 23,000 jobs, far below the expected increase of 80,000. The increase in June was also revised down to only 20,000. Despite the weak job market, the unemployment rate unexpectedly fell from 4.2% to 4.1%. "Fed mouthpiece" Nick Timiraos commented that in July, the U.S. unemployment rate dropped to 4.09% because both the number of job seekers and the number counted as unemployed decreased; this data brought the unemployment rate to its lowest level in two years.Analysts pointed out that this disappointing report has reignited concerns about the labor market and may complicate the Federal Reserve's interest rate decisions, as policymakers need to seek a balance between weak employment and persistent inflation. As a result, market expectations for interest rate hikes quickly receded.Affected by this, U.S. stock index futures surged rapidly, with Nasdaq futures up 0.79% for the day, S&P 500 futures up 0.39%, and Dow futures up 0.27%. U.S. Treasury prices soared, with the yield on the 10-year U.S. Treasury currently down 4.29 basis points, reported at 4.627%; non-U.S. currencies generally rose, with the dollar against the yen briefly falling 80 points, reported at 157.72.At the same time, the U.S. Dollar Index DXY briefly fell nearly 30 points, reported at 99.67. Spot gold briefly rose about $40, reported at $4,351.43 per ounce.

The Financial Services Agency of Japan and the National Police Agency jointly requested cryptocurrency exchanges to strengthen anti-fraud measures

According to CoinPost, the Financial Services Agency of Japan and the National Police Agency recently jointly sent a letter to the Japan Virtual Currency Exchange Association (JVCEA), requesting exchanges to strengthen anti-fraud measures. This request includes 11 specific requirements, such as the need for withdrawal addresses to be registered in advance, enhanced transaction monitoring, strict verification of identification documents when opening accounts, and setting a withdrawal limit for a certain period after users deposit fiat currency or purchase crypto assets.The background of this action is the increasing prevalence of investment scams and "pig butchering" schemes on social media, where criminals frequently use crypto accounts to transfer illegal funds. The Financial Services Agency also suggested that exchanges flexibly set withdrawal limits based on customers' risk levels and transaction purposes, and that suspicious transactions should immediately result in account restrictions or freezes, while enhancing intelligence cooperation with the police. For system renovations that are difficult to implement in the short term, exchanges are allowed to proceed in phases. In addition, the Financial Services Agency has officially established the "Cryptocurrency and Stablecoin Division," responsible for related regulatory affairs.

Hong Kong police updated on the virtual currency Fun Coffee scam, with total losses rising to approximately HKD 104 million

According to Hong Kong 01, the Hong Kong police updated information regarding the virtual currency Fun Coffee scam, revealing that as of August 5, a total of 255 related reports had been received, an increase of 30 from earlier, with total losses rising to approximately HKD 104 million. In addition, the Macau police arrested two women involved in 9 cases amounting to about 3.6 million Macau patacas.Regarding TVB artists who have hosted activities related to the Fun Coffee scam, the Hong Kong police stated that during the investigation, they would definitely contact the victims and relevant individuals to identify the mastermind behind the scam and their roles. Fun Coffee claims to be a large coffee investment enterprise in Phu Quoc, Vietnam, with a capital scale exceeding USD 1 billion. It entered the Hong Kong market by the end of 2025, packaging its image through marathons, banquets, social events, distributing flyers, and inviting artists to promote it, while registering a company, opening offices, and stores in Hong Kong. The actual operation was to lure citizens into downloading the app to complete tasks under the guise of investing in high-tech coffee equipment, gene optimization technology, and agricultural equipment, using Tether (USDT) and other cryptocurrencies for deposits. The platform promised annual returns of up to 197%--278%, with higher returns for larger amounts and longer deposit periods, and set up a commission structure to encourage recruitment. In July 2026, the Hong Kong Securities and Futures Commission listed it as a suspicious investment product. In late July of the same month, the app suddenly ceased operations, withdrawals became impossible, customer service went offline, and the offices and stores were vacated, leading to the collapse of the scam.
