$NAT · the second subsidy

Who's mining the second subsidy?
Live Bitcoin-pool adoption.

A pool “adopts” $NAT when it mines blocks that credit NAT — the amount decoded from each block's own bits field and auto-credited to the coinbase. Not a second chain, not a sidechain, nothing the miner runs. This page measures the share of recent Bitcoin hashrate doing that. It is adoption — not an endorsement, and not a price signal.

Adopts NAT vs. distributes NAT

A pool can credit NAT (the block's coinbase address receives it) without yet distributing NAT downstream to the individual hashers who pointed power at it. Most adopting pools credit; only two are confirmed to distribute it downstream to hashers so far.

Manually verified 2026-06-27 — not from any API. Downstream distribution is an off-chain pool-policy fact mempool.space does not expose; it is tracked by hand and may lag reality. Every other pool above credits NAT to the coinbase but is not (yet) confirmed to distribute it onward.
