According to CoinDesk, the developers of the Bitcoin Lightning Network payment software Core Lightning (CLN) issued an urgent warning to node operators after the team received a large number of AI-generated security reports, revealing several real vulnerabilities. The development team advised operators not to directly shut down the machine power but to restart the software in "--offline" mode, which stops communication with other Lightning Network nodes while still keeping it operational to continuously monitor the Bitcoin blockchain and protect the funds in the payment channels.The Core Lightning team began receiving a large number of AI-generated vulnerability reports since early August, some of which have been confirmed to be valid. Developers will keep the details confidential for two weeks to complete the patch development and plan to release a signed patch version for operators to verify the source. The source code and vulnerability details will be made public after the confidentiality period ends.This is the second AI-related security incident in the Lightning Network this month. Earlier in early August, BTCPay Server experienced a vulnerability that led to the leakage of credentials for some Lightning Network nodes and theft of funds. Additionally, the "Bitcoin Red Team," composed of 16 developers, used AI models to scan 390 Bitcoin code repositories at the end of July, discovering nearly 5,000 issues, 85 of which were rated as critical.

Reto Cueni, Chief Economist of St. Gallen Group, stated in a report that the market may slightly raise expectations for an interest rate hike at the Federal Reserve's September meeting. However, he pointed out that the market still mostly expects that the Federal Reserve will not raise interest rates, and St. Gallen Group itself currently does not believe there will be a rate hike.Cueni stated, "At present, we still maintain the judgment that the Federal Reserve will not further raise interest rates in the second half of this year." According to LSEG data, the money market currently estimates a 65% probability that the Federal Reserve will keep interest rates unchanged at the September meeting.

Core Lightning maintains that node operators should shut down their nodes unless they upgrade to an unreleased version. This warning was spread via Discord and amplified by Cashu protocol developer Calle, who stated that there is a serious vulnerability. The fix binary has not yet been released, and the details of the vulnerability are under a two-week confidentiality period.This is the fourth security alert for Bitcoin infrastructure in four weeks. Previously, a Coldcard firmware vulnerability led to approximately $114 million in BTC being stolen, and issues have also arisen with Boltz and BTCPay Server. The CLN team stated that they have received multiple AI-generated CVE reports in the past 10 days and are intensifying verification and fixes.

According to Bitcoin.com, blockchain analysis company Chainalysis announced the results of "Operation Lighthouse": this multinational operation focused on networks related to Child Sexual Abuse Material (CSAM) crimes, investigating 29,120 cryptocurrency addresses and digital identifiers, covering over 100 surface web and dark web platforms, forums, and distribution networks, generating 14,300 investigative leads, and identifying over 7,700 suspicious accounts and associated suspects across 125 countries.The operation was organized by the National Cyber-Forensics and Training Alliance in New York, involving at least 9 law enforcement agencies, more than 13 private entities and non-profit organizations, including Europol, the Australian Federal Police, the Royal Canadian Mounted Police, and the National Crime Agency of the UK. Chainalysis stated that the related leads may subsequently result in account restrictions, arrests, and prosecutions, with law enforcement outcomes expected to continue until 2027, and plans to expand this collaborative model to other cryptocurrency crime activities.

The decentralized perpetual contract protocol Lighter announced that its average block proof time has decreased from about 5.3 minutes to about 1 minute over the past month. This progress was achieved through two independent optimizations launched on July 23 and August 23. Lighter can now complete block verification faster, thereby increasing processing capacity, reducing infrastructure costs, and creating space for further expansion.The first optimization is the Heavy/Light decomposition. This solution splits the transaction circuit into light circuits and heavy circuits, allowing simple quote updates, which account for the vast majority of transactions, to only pay for light constraints, thus halving the proof time. The second optimization comes from the Prover backend optimization brought about by the proof competition held in collaboration with Eigen Labs, which again halves the proof time under the same circuit conditions. The first batch of optimizations went live on August 23, with more batches still in progress. Additionally, on August 10, all Schnorr signature verifications were incorporated into a single Plonky3 proof for each block, resulting in approximately a 20% improvement.The above optimizations are orthogonal and their effects are cumulative. The remaining competition optimizations are expected to bring about an additional 2x improvement, potentially reaching a total of about 10x compared to mid-July. Currently, Lighter's sustained processing capacity has exceeded historical peak loads, and the finality limit for withdrawals has been reduced from about 21-22 minutes to about 16-17 minutes, maintaining stability during peak traffic periods.

UPBIT will launch Lighter (LIT) on August 24 at 13:00 and support KRW trading. LIT is an Ethereum-based utility token primarily used for staking and liquidity participation in the Lighter protocol.

Lighter CEO Vladimir Novakovski stated at the first meeting of the CFTC Innovation Advisory Committee that DeFi should not be seen as the opposite of regulators, and that on-chain verifiable transaction records assist regulators in their work regarding transparency, consumer protection, and market fairness. He pointed out that decentralized verifiable finance is expected to become an important part of the future financial infrastructure in the United States, and the industry should promote the evolution of technology towards open-source and verifiable directions.Novakovski also mentioned that AI has the opportunity to drive financial democratization, allowing users to build trading strategies based on their own judgment, a capability that has primarily been available to high-net-worth individuals and professionals in the past. He also warned that the main risk of AI in the financial sector is consumer protection issues, such as users not understanding the actual functions of models or being misled by deceptive advertising, and suggested establishing a sandbox mechanism to validate the effectiveness and verifiability of AI models before large-scale application.
