Solana Validator Node Count Decreases by 68% in Three Years, Small Nodes Priced Out

2026.01.29 19:19:21

Cointelegraph reported on January 29 that data shows the number of validator nodes on the Solana network has dropped sharply—from a March 2023 high of 2,560 to the current 795, a 68% decline—sparking market concerns about the network’s decentralization. Industry insiders note that beyond purging “zombie nodes,” the core driver is the ongoing rise in operating costs plus zero-fee competition from large nodes, which is systematically squeezing out small and medium-sized validators. One independent validator operator said many small nodes aren’t bearish on Solana, but the economic model is no longer sustainable: “Without economic viability, decentralization becomes a charitable act.” Meanwhile, Solana’s Nakamoto Coefficient has fallen from 31 to 20 over the same period, a roughly 35% drop—indicating staked SOL control is shifting toward concentration in a handful of large nodes, reducing the network’s decentralization. Cost details include: - A minimum of $49,000 worth of SOL in the first year just to maintain operations (excluding hardware and servers); - Approximately 401 SOL per year for voting fees; - Daily voting transaction costs that can reach up to 1.1 SOL/day. The trend signal is clear: Solana is gradually shifting from a “broadly participatory node structure” to one dominated by large institutional nodes, which may have profound impacts on the network’s long-term security structure and governance landscape.

Claude launches real-time dashboard and animation tools: data auto-updates, with support for word-by-word video editing.

Beating AI News Flash: Anthropic rolls out two new features for Claude. Claude Dashboards turns enterprise data into real-time updated chart dashboards, while Claude Motion converts reports, charts, and product demos into short animations. Both tools are currently in testing. Dashboards supports integration with data platforms including BigQuery, Snowflake, and Databricks, and can also pull business data from Salesforce. Users only need to input natural language queries, and Claude will automatically generate SQL queries, extract data, and create charts. Dashboards update in real time as data changes. Clicking on chart figures also displays the corresponding query statement and last refresh time. For in-depth analysis, users can switch to professional tools such as PostHog and Grafana. Motion, however, does not rely on video generation models at all. Claude animates text, charts, and images by writing code. Users can freely modify numbers, text, and playback rhythm in the animation without regenerating the entire content. After completion, animations can be exported as MP4 files or handed over to other video editing tools for further processing. The two tools have different availability: Dashboards is accessible to Pro, Max, Team, and Enterprise users, while Motion is currently limited to Team and Enterprise plans. On the same day, Claude Docs, Slides, and Design officially exited beta testing and are now available to free users as well. Anthropic stated that the three tools have collectively generated over 45 million documents, slides, and design works to date.
