Decentralization is a Spectrum, Not a Binary State

No major blockchain is perfectly decentralized. It's measured across multiple axes:

· Physical/Node Decentralization: How distributed are the computers running the network? (Bitcoin scores very high here).

· Governance Decentralization: Who decides on protocol changes? Is it a core developer team, a foundation, or coin holders? (Often the weakest point).

· Developmental Decentralization: How many independent teams are building core client software?

Many popular networks are surprisingly centralized in practice, with a handful of entities controlling large portions of staking power (PoS) or mining pools (PoW). True decentralization is a slow, socio-technical challenge.
