first_img XRP Ledger upgrade Batch V1.1 is just one vote away from activation

The Batch V1.1 upgrade for the XRP Ledger is just one vote away from initiating the activation process. The RippleX team has fixed 11 software defects in the latest review. The Batch feature allows users to combine up to eight related transactions into a single operation, ensuring that both parties complete the transfer simultaneously when two people exchange tokens, thus avoiding the situation where one party pays while the other fails.In Tuesday's snapshot, the upgrade received support from 27 out of 35 trusted validators, accounting for approximately 77%, while changes to the XRP Ledger require an 80% support rate. Therefore, currently, one validator's vote can determine success or failure, and obtaining one more vote will initiate a two-week activation countdown. The support rate must remain above this threshold for 14 days, during which validators can change their votes.Previously, researchers discovered vulnerabilities in the original Batch proposal, allowing attackers to initiate transactions using others' accounts without authorization under specific conditions; this version was not deployed on the mainnet. The new version was released with xrpld 3.3.0 on August 6, and the latest review found 11 issues related to signatures, authorization checks, and server crashes. Among these, a serious vulnerability rated by the security company Common Prefix could allow attackers to reuse user signature permissions to execute transactions beyond expectations. RippleX stated that the review involved four senior engineers, audits from Halborn and Common Prefix, public security competitions, and automated testing, and mentioned that commercial projects using Batch have been signed or are in development.

Galaxy Research: Coldcard attackers continue to transfer funds, approximately 45% of the stolen assets have entered mixing or cross-chain pathways

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.

first_img Analysis: Japan's government bond yields hit a 30-year high, while Bitcoin is trading sideways at $78,000

According to Cointelegraph, the global bond bear market continues to ferment, with Japan's 10-year government bond yield rising to 3% on Tuesday, the first time since 1996; the 30-year government bond yield also broke through the historical high of 4.18%. The U.S. 10-year government bond yield simultaneously rose to a multi-year high of 4.78%, and global long-term sovereign bond yields are at their highest level since the 2008 financial crisis.In this context, Bitcoin remains in a sideways consolidation, maintaining around $78,000, slightly retreating from an earlier high of nearly $79,000. There is a dense resistance area between the current spot price and $86,000, which limits Bitcoin's upward momentum. Market sentiment remains cautiously optimistic in the short term, with the $76,000 to $82,000 range seen as a key battleground in the coming weeks.This round of selling occurred after U.S. Treasury Secretary Yellen announced an increase in the upper limit of government bond repurchase transactions to $4 billion starting in September, with some commentators likening it to a form of yield curve control. Arthur Hayes has long argued that the Federal Reserve will eventually activate the FIMA repo facility, a mechanism that will create new dollar liquidity, which is also why he recommends allocating Bitcoin, gold, and cryptocurrencies; Yellen hinted at the future use of this tool as early as August.
