Blockchain analytics firm Glassnode, in collaboration with ARK Invest, has published research drawing renewed attention to the blockchain trilemma and practical concentration risks facing major Layer 1 networks. The trilemma framework argues that blockchains typically optimize two of three properties—decentralization, security, and scalability—while sacrificing the third. Glassnode’s analysis indicates that Bitcoin leans toward security and decentralization but struggles with scalability; Ethereum has pursued scalability through ongoing upgrades, with trade-offs that may affect decentralization; and Solana offers high throughput at the potential expense of decentralization.
In a related research report covered on September 2, 2026, ARK Invest and Glassnode found that Bitcoin and Ethereum each require only three entities to reach critical control thresholds. By contrast, Solana requires 19 entities for a comparable level of control. The report also highlighted infrastructure differences: Bitcoin has a relatively balanced geographic node distribution, with around 63% of nodes running through Tor, while Ethereum shows greater reliance on centralized cloud providers, with approximately 20% of nodes hosted by AWS. These findings raise questions about governance, network influence, and long-term decentralization.
The market context is mixed. Traders are monitoring derivatives and options positioning for signs of shifting sentiment, and the report may prompt institutional investors and community members to reassess the governance and centralization assumptions behind these networks. Although the findings do not constitute immediate policy changes or price signals, they could influence regulatory scrutiny and investor narratives around Bitcoin, Ethereum, and Solana. Glassnode and ARK Invest emphasize transparency and data-driven evaluation of disruptive technologies, making the report a potentially important input for market participants.
