The Dogecoin network faced significant disruption as 69% of its nodes unexpectedly went offline, raising concerns about the cryptocurrency’s stability. Announced on Nov. 21, the incident was linked to a software flaw that caused widespread crashes among network participants. The sudden drop in active nodes temporarily slowed transaction processing and highlighted the importance of maintaining robust infrastructure for decentralized systems.

According to reports, the issue stemmed from an outdated version of the Dogecoin software still being used by many nodes. When these nodes encountered certain transaction types, they crashed, causing a chain reaction across the network. Developers and community members quickly mobilized to identify the flaw and urged node operators to update to the latest software version to restore normal operations.

The disruption has reignited debates about the challenges of maintaining decentralized networks, particularly for meme-based cryptocurrencies like Dogecoin, which rely heavily on community-driven efforts for development and upkeep. While the network has since stabilized, analysts have pointed out that such incidents expose vulnerabilities that could undermine trust in the system, especially during periods of high market activity.

Despite the setback, Dogecoin’s core development team has reaffirmed its commitment to improving the network’s resilience and security. Community members have also rallied to support efforts to upgrade and secure the infrastructure. The incident serves as a reminder of the critical role that active development and regular updates play in ensuring the long-term health of blockchain networks.

The city of Vancouver has taken a significant step toward embracing cryptocurrency, passing a motion to position itself as a Bitcoin-friendly city. Announced on Nov. 21, the initiative aims to foster innovation and attract blockchain-related businesses by creating a supportive environment for Bitcoin and other digital assets. City officials view the move as an opportunity to enhance Vancouver’s reputation as a hub for technology and finance.

The motion includes plans to explore Bitcoin payments for municipal services and assess the feasibility of integrating blockchain technology into public operations. Vancouver’s city council emphasized that this effort aligns with its goals of economic diversification and technological advancement. The city will also engage with local businesses and blockchain experts to develop a roadmap for Bitcoin adoption.

Vancouver has a long history of crypto engagement, being home to one of the first Bitcoin ATMs in the world. The new motion builds on this legacy by promoting broader adoption and usage of digital assets. City officials believe that positioning Vancouver as a leader in cryptocurrency could attract investments and boost economic growth, especially in emerging sectors like decentralized finance (DeFi) and Web3.

While the motion has been met with enthusiasm from the crypto community, some critics have raised concerns about regulatory challenges and potential risks associated with digital assets. However, proponents argue that proactive steps to embrace Bitcoin could provide Vancouver with a competitive edge in the global economy. The city’s efforts will be closely watched as it works to balance innovation with responsible governance.

The U.S. Supreme Court has refused to hear an appeal from Nvidia in a lawsuit accusing the tech giant of misleading investors about its sales linked to cryptocurrency mining. Announced on Nov. 21, the court’s decision leaves in place a lower court ruling that allows the case to proceed, potentially exposing Nvidia to significant legal and financial ramifications.

The lawsuit, filed by shareholders, alleges that Nvidia failed to disclose the extent to which its graphics processing unit (GPU) sales were driven by demand from cryptocurrency miners during the 2017-2018 crypto boom. Investors argue that the company’s misrepresentation inflated stock prices, causing substantial losses when the crypto market later crashed. Nvidia has consistently denied any wrongdoing.

The Supreme Court’s decision to decline the case marks a critical moment in the ongoing legal battle, as it paves the way for shareholders to pursue their claims in federal court. Analysts suggest that the case could set a precedent for how tech companies disclose information about their exposure to volatile markets like cryptocurrency. Nvidia has argued that its disclosures were adequate and aligned with regulatory requirements.

The development comes as regulators and investors increasingly scrutinize the intersection of traditional markets and cryptocurrencies. Nvidia, a dominant player in the GPU market, has since diversified its business, focusing on AI and gaming applications. However, the unresolved legal challenges highlight the risks associated with market speculation and transparency in the rapidly evolving crypto industry.
