According to Odaily Planet Daily, the number of active validators on the Solana network has decreased significantly over the past three years: from over 2,500 active nodes in March 2023 to approximately 800 currently, a drop of over 68%. Validators are responsible for running nodes, participating in block signing, and maintaining network security; changes in their number are generally considered an important indicator of decentralization. Ecosystem participants have offered different interpretations of this significant contraction. Some community members believe that this decline is mainly due to "Sybil nodes" leaving the network, arguing that "having 800 reliable validators is healthier than having 3,000 Sybil nodes," pointing out that reducing nodes that don't contribute significantly actually helps improve network quality. However, some infrastructure teams hold a different view. Developers from Layer 33 stated that they know many teams that recently shut down nodes, and these exits "are mostly not Sybil nodes," but rather chose to cease operations due to economic or technical factors. Therefore, a decrease in the number of validators cannot be simply equated with improved decentralization; its true impact depends on the independence and power distribution of the remaining nodes. The report indicates that discussions will continue, and Solana will continue to focus on reducing node operating costs and improving tool support to enhance the sustainability of network validators.

Huoxun Finance reported on December 9th that UXLINK CEO RollandSaf released a security incident review report, stating that the company suffered a total loss of over $11 million in the asset theft incident on September 22nd. He emphasized that the incident was not caused by internal factors within the project team, stating that attackers, by impersonating business partners and using deepfake video conferencing, compromised the personal devices of multiple SAFE authorized key holders over several months, stealing sensitive information such as passwords and private keys, and ultimately gaining control of the old version of the arb-UXLINK smart contract. The hackers then illegally issued tokens, transferred, and sold assets. RollandSaf stated that the hackers used compromised personal devices, not the UXLINK system. They used sophisticated impersonation and deepfake techniques. The team immediately filed criminal reports in multiple jurisdictions, including Asia, Europe, and the United States, upon the attack. Through immediate communication with exchanges, millions of dollars have been recovered, all of which have been used for buybacks to support community development. Furthermore, significant security upgrades have been implemented to signature devices, internal processes, and systems to prevent similar incidents from recurring. The DAO has passed a proposal to unlock an additional 12% supply ahead of schedule to help compensate users who purchased during the hack and illegal minting. All major exchanges have already received compensation.

Huoxun Finance reported on December 9th that, according to Cointelegraph, international credit rating agency Fitch Ratings warned it may conduct a negative reassessment of a US bank with "significant" involvement in cryptocurrencies. In a report released Sunday, Fitch stated that while the integrated use of cryptocurrencies can improve fee income, yields, and operational efficiency, it also poses "reputational, liquidity, operational, and compliance" risks to banks. Fitch also pointed out that although progress in US regulation has created a safer environment for the cryptocurrency industry, banks still face numerous challenges in handling cryptocurrencies. Fitch Ratings is one of the "Big Three" US credit rating agencies, alongside Moody's and S&P Global Ratings. These agencies' ratings carry significant weight in the financial world, influencing perceptions of businesses and investment decisions from an economic viability perspective. Therefore, a downgrade by Fitch of a bank with significant cryptocurrency involvement could lead to decreased investor confidence, increased borrowing costs, and ultimately, challenges to the bank's growth.
