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.

Japan National Police Agency: North Korea's cyber attack organization WaterPlum launched a large-scale attack targeting IT technicians

According to a joint alert issued by the Japanese National Police Agency, FBI, ASD/ACSC, BND, and BfV, the North Korean-backed cyber attack organization "WaterPlum" (also known as Contagious Interview) targets job seekers by disguising itself as an AI, cryptocurrency, and NFT company to post fake job listings. This lures job seekers into downloading NPM packages containing malware such as BeaverTail, InvisibleFerret, and OtterCookie, which then steal cryptocurrency wallet information and confidential data.As of July 2026, the organization has infected over 30,000 devices in more than 100 countries and regions worldwide, stealing information from over 7,000 cryptocurrency wallets, with the wallets under its control receiving at least approximately 1.7 billion yen (about 10.71 million USD) in cryptocurrency. The Japanese National Police Agency has discovered and dismantled a "notebook farm" established by local "supporters" for the first time in the country, where North Korean IT laborers remotely control PCs within the supporters' residences to conduct business, with the related amount involved reaching several hundred million yen.The police and FBI assess that WaterPlum and some North Korean IT laborers are under the unified command of the 313 Bureau of the Ministry of Military Industry of the Workers' Party of Korea, with the profits directly flowing into North Korea's national funding pool. The police remind IT technicians and corporate issuers to remain vigilant and avoid executing third-party code in unverified environments.

first_img Polymarket hires former Zora CEO to lead on-chain products

Polymarket announced the hiring of former Zora CEO Jacob Horne to lead product efforts, focusing on its DeFi business. Polymarket CEO Shayne Coplan acknowledged that as the company scales, the performance of its on-chain products has "declined," with some long-term users believing that Polymarket has shifted its focus to the U.S. market. Coplan stated that the company is working to unify its products but did not disclose a specific launch timeline, nor did he mention adjustments regarding fees, liquidity, or routing.Polymarket plans to hold a DeFi community meeting "soon" to gather feedback and announce a roadmap; in the meantime, users can provide feedback directly to Horne or Coplan. This appointment gives Horne broad product responsibilities rather than a specific engineering role. An earlier diagnosis came from Polymarket DeFi Engineering Vice President Josh Stevens, who noted on August 31 that the existing Central Limit Order Book (CLOB) is "full of technical debt." Although the team has scaled it tenfold and increased speed threefold, the underlying architecture still has flaws, and fixing one issue may trigger another.Stevens stated that the existing codebase is "unsalvageable in the long run," and the matching engine is being rewritten from scratch in Rust, with the goal of completing it in the latter half of the fourth quarter. Early benchmarks show that the new system's p99 latency is 10 to 20 times faster than the current system, capable of processing 200,000 orders per second, approximately 15 times the existing capacity.

first_img Ethereum Glamsterdam upgrade passed the rehearsal, scheduled to launch Sepolia on October 6

According to CoinDesk, the Ethereum Glamsterdam upgrade has continued to confirm blocks after adopting new block construction rules this week, passing key tests and paving the way for its planned launch on the Sepolia public testnet on October 6. The Nethermind client subsequently completed performance tests involving one of the biggest changes in Glamsterdam, with all 2,302 tests passing, processing 57.07 billion gas in 3 minutes and 15 seconds, averaging about 2.9 billion gas per second.The benchmark measures the speed of the Nethermind execution software rather than the entire network, testing block-level access lists. This mechanism informs Ethereum nodes in advance about which accounts and storage data will be used in the block, allowing nodes to fetch data and check unrelated transactions simultaneously, whereas the current Ethereum mostly processes related work sequentially, limiting the amount of activity each block can accommodate. About an hour after the testnet launch, Glamsterdam raised the block gas limit from 60 million to 200 million, freeing up space for more payments, token swaps, and other activities per block.The 200 million gas limit allows Ethereum to absorb more activity before users start bidding for block space, thereby alleviating fee spikes during transaction surges or when popular tokens are launched. Larger blocks are also harder to verify, which may make it difficult for small-scale operators to keep up. Glamsterdam aims to gain additional capacity without excessively increasing chain operating costs. This upgrade also extends the block data propagation time from about 2 seconds to 9 seconds and plans to incorporate the handover and payment of block construction and verification into Ethereum's own rules, reducing reliance on external relay services.

Huobi HTX Chief Analyst: The Fed's hawkish rate hikes reshape policy credibility

Regarding the Federal Reserve's decision to raise interest rates by 25 basis points as expected in the September meeting, Huobi HTX Chief Analyst Andy pointed out that what truly deserves attention is the comprehensive hawkish shift in the Federal Reserve's stance. All 12 officials rarely supported the decision unanimously, and the dot plot clearly indicates another rate hike within the year, with tightening becoming a consensus.The core message conveyed by the meeting is that the Federal Reserve is determined to rebuild its credibility against inflation at all costs. The economic forecast summary raised growth expectations and lowered the unemployment rate, reflecting confidence in a soft landing; however, the path for core inflation to decline has been significantly delayed, indicating that the higher-ups have accepted the reality of "higher for longer." Chairman Waller's statement is particularly crucial, placing anti-inflation efforts as an absolute priority. Even though the current economic fundamentals are robust and oil price fluctuations are supply-side factors, the Fed still chooses to respond with a tightening stance. This "better to be too tight than too loose" position has temporarily pushed up U.S. Treasury yields and the dollar, while suppressing gold.For the cryptocurrency market, uncertainty has actually decreased. A clearer policy path helps compress risk premiums, which is not a bad thing for risk assets in the medium to long term. The key going forward lies in data validation: if employment and growth remain strong, rate hikes may continue but at a slower pace; if the economy shows cracks, there is still room for a policy shift. Overall, the Federal Reserve is trading short-term pain for long-term policy credibility.
