Practical metrics (how I’d measure it)
- Nakamoto coefficient: minimum number of entities needed to halt the system (miners/validators/builders/sequencers).
- Stake/hashrate concentration (HHI), geographic/jurisdiction/provider diversity (e.g., cloud vs home-run nodes).
- Client diversity and implementation plurality (no single client >50%).
- Censorship-resistance: inclusion delay under adversarial pressure; share of blocks enforcing blacklists; availability of inclusion lists.
- Governance design: on-chain upgrade keys vs social consensus; ease of opting out; history of contentious forks.
- Economic centralization: MEV/builder/relay concentration; reliance on a few oracles/bridges/stablecoins.
- Verification costs: hardware/bandwidth for full nodes; light-client and stateless verification viability.
- L2/rollup dependencies: who controls sequencers/provers/upgrade keys and data availability.
