ARK Invest and Glassnode released a joint report, 'The Decentralization Spectrum: Design Tradeoffs In Digital Assets'. It compares Bitcoin, Ethereum and Solana across four design features and six measurable dimensions of decentralization.

The publication is important as an attempt to consider decentralization across several criteria rather than reducing it to a single characteristic. However, the available materials include only the Glassnode synopsis, so details of the conclusions, network assessments, and practical implications require verification against the full report.

The next useful signal is the release of the full text describing the six measurements, methodology, and results for each of the three networks. Substantial uncertainty remains: the provided data do not allow establishing which trade-offs the authors consider key or how they are measured.
