first_img Polygon has fixed security vulnerabilities through two hard forks, which were previously deployed privately

Polygon Labs disclosed that it has fixed a batch of security vulnerabilities in its proof-of-stake network through two hard forks, with the related fixes privately deployed before public disclosure. According to a forum post released on Wednesday, the team packaged the fixes into the Austin hard fork of the Bor client and the Kyoto hard fork of the Heimdall client, both of which followed the standard process for fixing issues that affect consensus: first validated on the Amoy testnet, and then publicly disclosed once the mainnet was activated and the network was secure.The Austin fork fixed two denial-of-service paths in block processing, including a vulnerability where malicious block producers could crash peer nodes by filling them with oversized field data. The Kyoto fork addressed a broader range of consensus hardening issues, with the most severe vulnerability allowing an attacker to force the entire validator set to perform costly and coordinated work with just one crafted transaction—the cost of constructing the transaction is low, but the network processing cost is high. Polygon emphasized that none of the vulnerabilities were observed to be exploited on the mainnet and have been proactively addressed. The two upgrades are now mandatory for node operators and have taken effect without the need for state migration or resynchronization.This disclosure comes at a critical transformation period for Polygon, which has completed the migration of the traditional MATIC token to POL as part of a comprehensive overhaul of its network architecture. The news did not boost the price of POL; according to CoinGecko data, POL traded at approximately $0.09983 on Sunday, down 2.3% in 24 hours, down about 6.8% over the past week, and down about 60.8% over the past year, with a market capitalization of approximately $1.07 billion.

first_img The prediction market platform Kalshi becomes the exclusive partner of the US Open

According to Front Office Sports, the prediction market platform Kalshi has signed an exclusive agreement with the United States Tennis Association (USTA) to become the exclusive prediction market platform partner for the US Open. The agreement is effective immediately and was finalized only after the qualification rounds ended last week, with the report not disclosing financial terms. Kalshi has not yet been listed among the official partners of the US Open, and a blog post analyzing the women's singles events released earlier by the company included a statement saying that the company "is not affiliated with the US Open or WTA."According to sources, as part of the agreement, the USTA is preventing other prediction market platforms from advertising at US Open venues and on television, including ESPN's broadcasts of the events, which is an unusual aspect of the agreement. Kalshi declined to comment, and representatives from USTA and ESPN did not respond immediately. The US Open is owned and operated by the USTA, and its CEO Craig Tiley took office on July 20 of this year, playing a significant role in facilitating this year's event agreement.Both Kalshi and Polymarket are official partners of the NHL, and Kalshi has recently partnered with several MLB teams. According to data from The Block, since August, the total trading volume for Kalshi, Polymarket, and Polymarket US has reached $41.2 billion, with Kalshi accounting for $33.7 billion.

first_img Chainalysis sues ICE for exclusively awarding a $94.6 million blockchain analysis contract to TRM Labs

Blockchain analysis company Chainalysis has filed a lawsuit in the U.S. Federal Claims Court, accusing the U.S. Immigration and Customs Enforcement (ICE) of illegally awarding a $94.6 million exclusive contract to competitor TRM Labs. This contract provides forensic software and support services for investigations by the Department of Homeland Security's task force, with a performance period from July 1, 2026, to June 30, 2027. Chainalysis claims this is the largest blockchain analysis contract awarded by the U.S. government to date.In the complaint, Chainalysis points out that ICE issued a Request for Information (RFI) on May 28, which included 18 questions related to capabilities such as a proprietary fraud victim database, AI agent data retrieval, automated notifications for virtual asset service providers (VASP) to execute voluntary freezes, and collaboration with stablecoin issuers. However, many of the RFI requests did not appear in the final Statement of Need released less than two weeks later, while ICE's market research determined that Chainalysis could not meet the requirements based on RFI standards. Chainalysis also noted that "sexual extortion," which was not mentioned in the RFI, became one of the three main task areas in the Statement of Need, and some requirements closely matched TRM's proprietary product architecture.Chainalysis claims it was the only company to submit a capability statement, but ICE completed its market research the next day, determining that TRM was the only vendor capable of meeting all the requirements, and did not pose any follow-up questions to it.

Zhao Changpeng: This year has not been a good year for the crypto field, but the progress of RWA and stablecoins is unexpected

Zhao Changpeng appeared on the podcast "Meanders" and discussed the pressures, adaptability, and lifelong motivation in the cryptocurrency field. When talking about pressure, Zhao Changpeng stated, "I generally do not set goals; I just do my best. This year the market is not good, so the company's performance may decline, but I have tried my best, I did not slack off, and I did not make any major mistakes. I handle problems in the same way.""No matter how difficult the problem is, I just try my best to deal with it. I also believe in simulation theory; I believe this world is simulated, so it’s like a game. It is simulated, but that does not mean this game is unimportant. However, in this game, I just need to do my best; you try your best to handle it, and after handling it, you can only wait, just lie back and win."Zhao Changpeng mentioned the industry, saying, "As for blockchain itself, I think the improvement in performance is still too slow. But because Bitcoin upgrades slowly, it is particularly stable, which is also an advantage. So there are advantages and disadvantages. Many of the ideas we had in the early days had many implementations, many that were not implemented, and many unexpected things happened."Regarding RWA, he said, "Even a year and a half ago, I would have doubted whether RWA could succeed, but now it is growing very fast. To be honest, I might have had some doubts about stablecoins five years ago, wondering how long they could last; at that time, I did not fully understand them. Stablecoins have their own uses. So these things are all things we did not think of before."

Former Vice Chairman of the Federal Reserve: The default choice now is to raise interest rates, and Waller's speech reverses the previous logic of the Federal Reserve

Nick Timiraos, the "Fed Whisperer," stated that Fed Chair Waller has quelled some concerns about his strategy to combat inflation, but has also laid the groundwork for a larger test that may come in three weeks. If the Fed raises interest rates, it could anger the White House just weeks before the midterm elections. If they hold steady, it may reignite the doubts that Waller's remarks have calmed.Two points from Waller's speech on Friday particularly suggest that the Fed may raise rates next month. The first point is that Waller finds it difficult to describe the current financial conditions as restrictive. The second point is that the relatively positive inflation data over the summer has not convinced him that the underlying trend is improving. The Fed's default choice before Friday was to hold steady unless the data was strong enough to warrant action.Former Fed Vice Chair Cohen stated that Waller's remarks have reversed this logic. "He has changed the original assumption; it is now that they will raise rates unless the data shows it is unnecessary." This means that the final decision will depend on changes in the situation before the September meeting, especially the August CPI released on September 11. Cohen stated that if the data indicates that action is unnecessary, the Fed should not raise rates; if the data is strong, it could weaken the argument that inflation is moving back toward the Fed's 2% target.

Forbes: Europe is accelerating the construction of alternatives to the US dollar stablecoin, with the digital euro and private stablecoins advancing on two fronts

As the US dollar stablecoin continues to dominate the on-chain payment market, Europe is accelerating the development of a digital currency system that reflects its own regulatory framework, monetary sovereignty, and privacy standards, gradually forming two parallel paths: "digital euro + private euro stablecoin." Among them, the European Central Bank is prioritizing privacy protection as an important design focus for the digital euro. Piero Cipollone, a member of the Executive Board of the European Central Bank, stated that the digital euro will provide the highest possible level of privacy under current technological conditions, with offline payments visible only to the payer and payee; in online transactions, the euro system cannot directly identify specific individuals, but banks can still obtain the information required for anti-money laundering.At the same time, private institutions have taken the lead in promoting euro stablecoins. Revolut has begun rolling out EURR to some users in Denmark, Poland, and Portugal, with plans to expand to the entire European Economic Area in the future. EURR operates on Ethereum and is issued by Bridge Building, a subsidiary of Stripe, aiming to maintain a stable value against 1 euro. Forbes points out that the digital euro and EURR are not simply in a substitutive relationship: the former is a public currency issued by the central bank, while the latter is a privately issued on-chain stablecoin. The European digital currency market is developing along these two models simultaneously, with competition focusing on privacy, usability, regulatory clarity, and actual economic value.
