Bitcoin vs Cardano

Which is more decentralized — Bitcoin or Cardano? A side-by-side on consensus, nodes, clients and governance.

	Bitcoin	Cardano
Grade	B+	A-
Type	L1 · PoW	L1 · PoS (Ouroboros)
Nakamoto coefficient	~2–3*	50+
Node / validator set	~20,000+ reachable full nodes	~3,000 stake pools
Clients / sequencer	Bitcoin Core dominant; alternatives exist	Mostly one node implementation (a concentration risk)
Governance	No formal governance (BIP + social consensus)	On-chain (CIP-1694 / Voltaire)
Key risk	Mining-pool concentration	A few large stake pools still matter

Bitcoin B+

Largest reachable full-node set
No foundation / no on-chain governance to capture
Maximally credibly neutral

Mining hashpower concentrated in a few pools
Bitcoin Core client dominance

Cardano A-

Very high Nakamoto coefficient (50+)
~3,000 independent stake pools
On-chain, token-holder governance

Limited node-client diversity
Founding entities still influential

Bottom line

Unmatched on node-level and political decentralization; mining-pool concentration is the asterisk. Among the most decentralized L1s by consensus, held back mainly by client monoculture.
