Solana vs Bitcoin

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

	Solana	Bitcoin
Grade	C+	B+
Type	L1 · PoS + PoH	L1 · PoW
Nakamoto coefficient	~29	~2–3*
Node / validator set	~770 validators (down from ~2,560 in 2023)	~20,000+ reachable full nodes
Clients / sequencer	Agave + Firedancer (diversifying)	Bitcoin Core dominant; alternatives exist
Governance	Off-chain + foundation programs (SFDP)	No formal governance (BIP + social consensus)
Key risk	Validator count fell ~65% to ~770	Mining-pool concentration

Solana C+

Nakamoto coefficient ~29
Adding a second client (Firedancer)
Geographically distributed validators

Validator count down ~65% since 2023
High hardware cost to run a node

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

Mid-tier and improving on clients, but the falling validator count is a real concern. Unmatched on node-level and political decentralization; mining-pool concentration is the asterisk.
