According to monitoring by ai_9684xtpa, Hyperliquid trader DoshiAtoll opened a short position of 1,576.23 BTC at 8 AM today, valued at roughly $100 million. The short entry price was $64,039, with 40x leverage, and it currently has an unrealized profit of approximately $456,000. Following the establishment of this position, the two largest BTC holdings on the Hyperliquid platform are now both BTC short positions, drawing market attention to the bearish sentiment of large capital.

According to Lookonchain monitoring, Japanese Bitcoin reserve firm MetaPlanet transferred 1,473 BTC an hour ago, worth roughly $93.82 million. Separately, Bitcoin miner Hut 8 moved 493 BTC three hours ago, valued at approximately $31.36 million. The two firms collectively transferred a total of 1,966 BTC, with a combined value of around $125 million.

According to official announcements, Bithumb will list the TRB/KRW trading pair.

The cross-chain bridge connecting the XRP Ledger and Coreum was hacked on August 9, with attackers exploiting a vulnerability to steal approximately 199,916 XRP, reducing the bridge’s asset balance from roughly 200,410 XRP to just 493.5 XRP. Analysis indicates the attack targeted neither the XRP Ledger itself nor involved any private key leaks, instead exploiting a flaw in the Coreum cross-chain bridge’s validation logic. The attackers forged fake deposit operations, tricking the bridge system into recognizing them as legitimate deposits, which triggered the other end of the bridge wallet to send actual XRP to the attackers. On-chain data shows the attackers completed the fund transfer in 97 minutes via 94 multi-sig authorization transactions. These transactions required 17 out of 28 relay node keys to sign off, meaning the attackers successfully bypassed the bridge system’s validation mechanism. As of August 11, the Coreum cross-chain bridge remains suspended, and the Coreum Development Foundation has not yet released an official incident report. The incident affected third-party cross-chain infrastructure, not a vulnerability in the XRP Ledger protocol layer, and the security of the XRP mainnet and user private keys was not compromised.

AI security startup Attestable announced its official launch and a $20 million seed round funding. The round was led by Jamin Ball of Altimeter Capital and Yonatan Mandelbaum of TLV Partners, with participation from firms including Halcyon Futures, Cerca Partners, and several individual investors. Attestable founder Yogi stated that as AI increasingly integrates into critical infrastructure, national security, and large enterprise systems, verifying the trustworthiness of AI operations has become a key global issue. The company aims to build a universal verification layer for cutting-edge AI labs, critical infrastructure, and national-level applications. According to the introduction, Attestable uses Zero-Knowledge Proof (ZKP) technology to shift trust in AI systems from data centers to mathematical verification mechanisms. This technology can confirm that an approved model, its weights, input data, and operational policies indeed generate specific outputs, without disclosing model parameters or user privacy data, and verification can be completed without re-running the model. Attestable noted that its technology has now achieved verification inference of Meta’s Muse Glimmer 30B model on a single NVIDIA H100 GPU, reaching a speed of 85 tokens per second. The generated proof is small in size, features quantum-resistant security, and enables fast verification. In response, Ethereum co-founder Vitalik Buterin published a post stating that this achievement brings the performance overhead of zero-knowledge proofs for large language models (LLMs) close to single-digit levels. He added that the next challenge is to further reduce the performance costs of technologies such as Fully Homomorphic Encryption (FHE).
