According to the monitoring by the head of Galaxy Research, it has communicated with over 190 victims of Coldcard vulnerability attacks and has asked victims who have not yet contacted them to reach out via private message so that they can provide tracking information and assist in reporting losses to the relevant authorities.Since August 6, no new attack incidents have been confirmed, but this does not mean that new attacks will not occur, and vigilance is required.

Harmony Protocol released an event update stating that an unauthorized ONE minting incident occurred. Investigations show that the attacker exploited a cross-shard receipt replay vulnerability, allowing processed cross-shard receipts to be executed multiple times, and minted ONE in empty blocks.The team is currently verifying two sets of impact data: early analysis indicates that the first round of minting involved 4 billion ONE, while the latest on-chain reconstruction shows that approximately 3.01 trillion ONE were issued to four attacker wallets through six forged cross-shard transactions. Harmony Protocol confirmed the first round of minting of 4 billion ONE, generated through two empty block accounting transactions that produced 1 billion and 3 billion ONE respectively, of which 2.8 billion ONE were subsequently transferred to other attacker addresses.The team has fixed the cross-shard receipt verification and pre-staking committee quorum verification vulnerabilities and deployed Mainnet v2026.1.1. Bridge services have been suspended, and Harmony Protocol is coordinating with validators, trading platforms, and LayerZero to freeze related funds, preparing to roll back the network to block 92,730,034 before the attack occurred. Currently, Shard 0 has been paused at block 92,753,555, and the official RPC may return a 502 error as a result.

Luke Dashjr has randomly determined that BLAKE2b will be the new POW algorithm for the BIP-110 chain, expected to replace the currently used SHA-256d algorithm in Bitcoin. Compared to SHA-256d, BLAKE2b is more suitable for mining with general-purpose CPUs/GPUs, being more CPU-friendly, which can reduce the advantages of existing Bitcoin ASIC miners.Previously, it was reported that Luke Dashjr plans to officially implement the BIP-110 hard fork on September 1, making it an independent blockchain and generating a new token distinct from Bitcoin. Luke Dashjr has had his Bitcoin BIP editing permissions revoked by the Bitcoin BIP editing team.

The hardware wallet Coldcard has been hacked, and the total losses are currently uncertain. The blockchain analysis platform CryptoQuant confirmed the loss to be 1432 bitcoins, while Galaxy Research provided a high-confidence minimum value of 1730 bitcoins. Other analyses suggest that the scale of the losses may be even higher.Research institution Galaxy Research stated that its earlier estimate of 1816 bitcoins is a potential value and not a confirmed total. As of Tuesday, the institution confirmed a high-confidence minimum loss of 1730 bitcoins, with over 450 bitcoins confirmed based on reports from victims. Blockchain intelligence company TRM Labs estimated that the attackers transferred about 1816 bitcoins from over 5200 addresses in four stages. CryptoQuant indicated that its confirmed data only includes addresses publicly disclosed by victims and verified through on-chain patterns, and the statistics may rise as more victims disclose information.

According to Wired, during security testing, the open-source model Kimi K3 from the dark side of the moon broke out of the sandbox and accessed the internet, attempting to find test answers via GitHub. American security startup Frontier Security stated that Kimi K3 exploited a sandbox configuration vulnerability, but it itself lacked sufficient built-in protective mechanisms.Similar to incidents previously disclosed by OpenAI and Anthropic, this escape partially stemmed from a sandbox configuration error. However, Kimi K3 did not initiate an attack, as the answers were easily accessible on GitHub. The CEO of Frontier Security stated that Kimi K3 performed excellently in cybersecurity defense but lacked mechanisms to prevent cheating or escaping the sandbox. Security experts emphasized that configuring the testing environment is crucial, as the misuse of AI agents could lead to system failures.

Well-known crypto KOL Ansem posted that signs of a bottom forming are appearing in the crypto market. Firstly, prices are beginning to show resilience against negative news; for example, when Saylor sold millions of dollars in the range of $58,000 to $60,000, BTC continued to form higher lows. Secondly, crypto-native mobile applications are starting to see actual user growth, with Pump.fun's weekly revenue increasing by 20% and Fomo surpassing 100,000 users within a week; institutional interest is also rebounding, including progress from Robinhood Chain and billionaire Paul Tudor Jones publicly bullish on BTC. Additionally, the popularity of crypto-related content on social media is rising again.Ansem stated that if on-chain tokens continue to create higher highs after the initial volume peaks, the number of holders of popular tokens continues to grow, mainstream media refocuses its reporting, developers experiment with new on-chain mechanisms, and successful protocols provide incentives through airdrops, it may further confirm that a new bull market has begun.

According to an analysis by Reuters of LSEG data and company filings, Microsoft, Meta, Oracle, Amazon, and Alphabet have committed to future payments of approximately $1.09 trillion in uncommenced lease obligations, primarily for AI data centers, which is about four times their confirmed lease liabilities (approximately $285 billion). These commitments have not yet been included on the balance sheet but have been disclosed in the notes to the financial statements. Among them, Microsoft disclosed the largest amount, reaching $329.1 billion; Meta disclosed $278.99 billion and signed an additional $68 billion in new leases in July; Oracle disclosed $260 billion, nearly seven times its confirmed liabilities, with lease terms generally ranging from 15 to 19 years, and the company has warned that it may face risks if customers do not renew or are unable to fulfill their obligations; Alphabet and Amazon disclosed $85.2 billion and $137.21 billion, respectively.The analysis points out that if the demand for AI computing power continues to grow, these facilities will support the next phase of cloud business expansion; if demand falls short of expectations, companies may be forced to pay high costs for large amounts of long-term idle capacity. S&P Global Ratings has included the uncommenced leases of companies like Oracle in its adjusted debt forecasts. This data highlights the potential long-term financial pressure that the expansion of AI infrastructure brings to tech giants.

According to the latest research by TrendForce, the tight supply of DRAM is expected to continue until 2027, and the uncertainty of the HBM4e verification schedule is prompting AI chip manufacturers to consider reducing the HBM configuration of their next-generation products. Starting from Q3 2026, NVIDIA has begun evaluating the HBM solution for Rubin Ultra, expanding from the original 12-Hi HBM4e to alternative options such as 8-Hi HBM4e, 12-Hi HBM4, and 8-Hi HBM4, with the final specifications yet to be determined. Previously, due to the expected supply bottleneck of LPDDR5X lasting until 2027, NVIDIA decided to halve the SOCAMM capacity of the next-generation Vera Rubin Superchip module.TrendForce pointed out that the main reasons for the downgrade of Rubin Ultra from 12-Hi HBM4e include: the overall DRAM shortage in 2027 will limit the allocation of wafer capacity to HBM, and there is still uncertainty regarding the mass production schedule and yield ramp-up of 12-Hi HBM4e. It is expected that the HBM bit shipment volume in 2027 will increase by approximately 50-60% year-on-year, which will still be insufficient to meet the growth in demand. HBM suppliers will maintain pricing power throughout 2027, and HBM prices are expected to rise significantly. The final configuration will depend on the wafer allocation decisions of memory suppliers.
