A decentralization rating of BTC, ETH, SOL, XRP, ADA, AVAX, and TRX using six indicators shows ETH and ADA as the most decentralized, with XRP and TRX being the most centralized. The study employs a simple model to gauge decentralization, with ETH rated the highest and SOL more decentralized than BTC. However, no single blockchain dominates in all aspects, necessitating a multi-dimensional approach to assess decentralization.
