Bitdeer has achieved 70 EH/s in self-mining operations while managing a total hashrate of 78.1 EH/s across its combined fleet, positioning itself as a top contender in bitcoin mining by computational power. This milestone reflects significant growth in Bitdeer's mining infrastructure and competitive standing within the industry.
Bitcoin Core's governance has evolved from Satoshi Nakamoto's solo merge authority to a distributed maintainer model with key figures like Ava Chow, Gloria Zhao, and TheCharlatan controlling code changes. This merit-based consensus system safeguards a $2T+ network by preventing unilateral control while ensuring technical quality and decentralized decision-making.
Researchers propose an attribution-driven approach to make encoder-based Large Language Models more transparent and trustworthy for network intrusion detection in Software-Defined Networks. By analyzing which traffic features drive model decisions, the study demonstrates that LLMs learn legitimate attack behavior patterns, addressing a critical barrier to deploying AI security tools in sensitive environments.
When seven submarine internet cables were severed off Côte d'Ivoire in March 2024, causing severe regional internet disruption with an IODA severity score above 11,000, Bitcoin's network barely felt the impact. The affected region hosted only about five Bitcoin nodes (0.03% of the network), resulting in a negligible -2.5% fluctuation within normal parameters, demonstrating Bitcoin's network resilience despite researchers identifying potential chokepoints.
Bitwise announced it will donate $233,000 to support Bitcoin open-source developers who maintain and secure the Bitcoin network. This contribution represents corporate backing for the decentralized development ecosystem that keeps Bitcoin operational.
Researchers developed ThreatFormer-IDS, a Transformer-based intrusion detection system that achieves robust cybersecurity monitoring for IoT and industrial networks. The system demonstrates superior performance in detecting zero-day attacks while providing explainable threat attribution, achieving 99.4% AUC-ROC on benchmark tests.
Researchers developed AMDS, an attack-aware multi-stage defense system for network intrusion detection that uses adaptive weight learning to counter adversarial attacks. The system achieved 94.2% AUC and improved classification accuracy by 4.5 percentage points over existing adversarially trained ensembles by learning attack-specific detection strategies.
Bitcoin mining experts believe the Iran conflict will not significantly impact Bitcoin's network hashrate or mining operations. Despite concerns about geopolitical tensions, Bitcoin's decentralized network is expected to remain resilient to regional disruptions.
Researchers conducted a benchmark study on IoT botnet intrusion detection systems, finding that models trained on one network domain suffer significant performance degradation when applied to different environments. The study evaluated three feature sets across four IoT datasets and provided guidelines for improving cross-domain robustness through better feature engineering and algorithm selection.
U.S. strikes on Iran have raised questions about potential impacts on Bitcoin's network stability, given Iran's estimated control of approximately 5% of global hashrate. However, observers note that Bitcoin's network would continue operating without disruption even if Iran's mining operations were affected.
Ethereum staking has reached a new milestone with over 30% of ETH's circulating supply now being staked to secure the network. This record-high staking participation occurs despite ETH's recent price decline, indicating strong long-term confidence in the network.
