Cardano vs Bitcoin

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

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

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

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

Bottom line

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