Research institution Galaxy Research recorded a reorganization event at Bitcoin block height 966500, where mining pools Spiderpool and Antpool simultaneously discovered two valid blocks pointing to the same parent block, leading to a brief competition. Ultimately, the Antpool block joined the chain with a higher cumulative work, while the Spiderpool block was discarded.Galaxy Research stated that this is the third single-block reorganization that has occurred in Bitcoin in the past four weeks, with the previous two occurring at block heights 962722 and 963853. Its nodes only observed the block after the Antpool block completed confirmation and continued to extend on it. When a single-block reorganization occurs, the network will ultimately continue to build along the chain with the higher cumulative work, while the other block is removed from the chain. Monero has experienced an 18-block reorganization, and Bitcoin SV had a 100-block reorganization in 2021; if a transaction is in a block that is replaced, its confirmations will disappear.

According to CNBC, Ant International has launched a collaboration with Visa and Mastercard to establish a "Know Your Agent" (KYA) interoperability framework, which will set universal standards for AI agent identity recognition, verification, and transaction monitoring, allowing agents verified on one network to be used across ecosystems.McKinsey estimates that by 2030, AI agents could participate in $30 trillion to $50 trillion in global consumer transactions.

Mastercard recently released the report "A Short History of the Future of Shopping and Payments," predicting that by 2030, approximately 300 million shoppers worldwide will regularly use AI agents, primarily concentrated in the United States, the United Kingdom, the Netherlands, China, and South Korea. The report is based on a survey conducted from June to July 2026 involving 13 markets and 13,000 pairs of parents and teenagers (a total of 26,000 respondents).The survey shows that 65% of British teenagers believe AI will change the shopping habits of their generation, and the likelihood of teenagers globally using AI for shopping is about twice that of their parents. 22% of British teenagers expect shopping to be dominated by AI within five years, compared to only 11% in France. 79% of teenagers and 70% of parents have used AI to research products in the past year, while 51% of teenagers and 46% of parents have used AI to complete a purchase at least once.The report cites Gartner's prediction that by 2028, the majority of B2B procurement will be mediated by AI agents, driving over $15 trillion in spending; by 2030, 20% of monetary transactions will be programmable. The report also suggests that "Know Your Agent" (KYA) could become a compliance advantage, with payment intent, consent, and machine-readable warranties forming the infrastructure of agent-based commerce.

According to Bitcoin News monitoring, DART stated that it, along with independent white hat researchers, has recovered over 50 BTC from wallets affected by the COLDCARD entropy vulnerability, completing the transfer before malicious attackers could steal them. DART is a digital asset recovery organization that collaborates with white hat researchers to protect vulnerable funds and coordinates their legal return to the owners.The white hat researchers did not request a bounty and will return the Bitcoin to the owners. The recovered BTC has been transferred to the Crypto Recovery Trust. This trust is a dedicated statutory trust established under Wyoming state law to hold recovered digital assets and return them after confirming and verifying the legitimate owners.The trust will document the recovery process, separating the BTC from DART and the researchers' funds, conducting blockchain analysis, ownership verification, and sanctions screening, and providing a legal return process for verified owners. If there is a dispute over ownership, or if the related funds are involved in sanctions or criminal proceedings, the BTC will be handled according to applicable legal procedures. DART stated that other vulnerable assets and recovery leads are still under review.

According to Bitcoin News monitoring, Coldcard thieves are prioritizing the emptying of the largest portion of the third wave vaults. Galaxy Research indicates that these wallets have transferred out 97.09 BTC, worth approximately 7.7 million dollars, accounting for about 45% of the assets in this batch.The attackers created 293 2/2 vaults themselves, and had transferred some tokens through THORChain on September 2, subsequently moving them into multiple rounds of CoinJoin over the weekend. The vulnerability originated from a firmware flaw in 2021, which reduced the seed entropy to a minimum of 40 bits. Of the tokens stolen in this exploit, approximately 82% have not yet been transferred.

Visa stated in an official blog post that stablecoin-linked cards are one of the fastest-growing segments of the network. In the second fiscal quarter, over 160 stablecoin-linked card projects launched globally, with payment volumes increasing nearly 200% year-over-year, and an annualized settlement rate exceeding $20 billion, growing more than 15 times year-over-year.Visa pointed out that its collaboration with Credit Coop to launch a stablecoin-based revolving credit tool provides daily settlement funds for early stablecoin card projects, and the borrowing costs for some participating projects have decreased by more than 30%.

According to a report by Decrypt, Galaxy Research stated that the third wave of attackers on the Coldcard hardware wallet has recently transferred 97.09 BTC, worth approximately 7.7 million dollars at current prices, accounting for about 45% of the stolen Bitcoin in this wave.Among them, the attackers transferred about 20.5 BTC to Ethereum via THORChain cross-chain on September 2; subsequently, they moved some funds into the CoinJoin mixing process to increase the difficulty of tracking the funds. Currently, 11 of the 293 2-of-2 multi-signature addresses established by the attackers in the third wave have been emptied.The report indicated that this Coldcard security incident originated from a firmware vulnerability introduced in 2021, which significantly reduced the randomness of wallet mnemonic phrase generation, allowing attackers to potentially reconstruct private keys offline and steal funds. As of now, approximately 82% of the stolen BTC in the entire Coldcard attack incident has not yet been transferred.Galaxy Research believes that if the newly discovered suspected victim addresses are included in the statistics, the total amount of stolen BTC may reach about 1,806, worth approximately 144 million dollars.

Galaxy Research published that the attackers in the Coldcard "Wave 3" attack are still continuously transferring the stolen funds. During this phase, the attackers created 293 2-of-2 multi-signature wallets for each victim's assets. The first batch of funds was transferred across chains to Ethereum via THORChain; the latest round of transfers has begun entering the CoinJoin mixing process.Currently, the Wave 3 attackers are processing the largest amounts of stolen funds in order of the stolen amount, having sequentially transferred the funds from wallets ranked 1 to 11. The next 10 wallets that have not yet been transferred hold a total of 30.81 BTC, while wallets ranked 61 to 293 hold a total of 33.77 BTC. So far, the attackers have transferred about 45% of the stolen assets from this exploit, with funds flowing to Ethereum (via THORChain) or entering CoinJoin mixing transactions. Additionally, this fund transfer has revealed a previously unknown wallet: 58 addresses jointly spent in a 2-of-2 multi-signature format identical to that of Wave 3, and these were further transferred by the Wave 3 attackers to a jump address that funds CoinJoin.The on-chain analysis team currently marks this wallet as "cause = open," but believes it likely also belongs to Coldcard victims, which means the number of wallets involved in Wave 3 may increase to 294, raising the previously reported total amount stolen from the Coldcard vulnerability to approximately 1806 BTC. Currently, about 82% of the stolen BTC remains in addresses initially controlled by the attackers, while about 18% has been transferred, with the flow of funds indicating that it may be undergoing laundering processes.

ASUS and Gigabyte, among other graphics card manufacturers, plan to raise product prices in the mainland Chinese market again in September, by up to 500 yuan (approximately 2,300 New Taiwan dollars). The price increase effect will also boost the performance of ASUS, Gigabyte, MSI, Leadtek, and Chengqi.According to reports from mainland Chinese media IT Home, ASUS will raise the net cost price of the NVIDIA RTX 5070 series by 150 to 300 yuan in September, while prices for other series models will remain unchanged. Gigabyte will increase the price of all models in the NVIDIA RTX 5060TI 16G series by 200 yuan in September, while other models will remain the same. AMD's RX 9070 XT series will increase by 200 yuan; the RX 9060 XT 16G/8G series will increase by 200 to 250 yuan; and the RX 7650 GRE series will increase by 400 yuan.The main reason for the price increase is the shortage of memory, and production capacity has also shifted towards manufacturing AI computing power GPUs. NVIDIA has again lowered the overall shipment volume of consumer GPUs by 15% to 20% for the third quarter, and the estimated supply for various brands in September is similar to that in August, with supply still tight. The high-end models such as the NVIDIA RTX 5080 and 5070 TI remain among the most out-of-stock models. This year, NVIDIA has raised graphics card prices multiple times, and September marks another increase.
