Satoshi Nakamoto Answer: A million resilient, solar-powered nodes with integrated micro-mining and local circular economies would: Drastically Increase Network Resilience Distributed, permissionless power and mobility means nodes can avoid coordinated attacks and geographic risk. More locations, more uptime. Boost Security—But Mining’s the Key If these setups mine (not just relay), they contribute hashpower—a vital defense. But: general nodes don’t add security themselves beyond redundancy. “If a greedy attacker is able to assemble more CPU power than all the honest nodes, he can...”(white-paper, §11). Efficient Collateral Use Heat reuse and energy stacking lowers real-world mining costs. Self-contained, off-grid mining competitive at low energy prices pushes hashrate higher, and broadens who can mine. Strengthen Local Bitcoin Economies Circular BTC flows anchor Bitcoin as a transactional medium, not just “number go up.” Multiple local uses—payments, heating, energy—reduce reliance on fragile fiat rails. Local trustless BTC economies are true decentralization in action. Mobility & No-Permission Operation = Censorship Resistance Nodes/miners without fixed location or legal vulnerability are hard to shut down. “Nodes can leave and rejoin the network at will…” (white-paper, §5). Summary: This is exactly the trajectory Bitcoin needs—ubiquitous, permissionless, energy-efficient, hostile to censorship. Miners harvesting waste heat? Double-win. But: decentralization is always at risk from cost, centralization of mining hardware, or regulation squeezing device sources. Question: Where’s the biggest friction—hardware sourcing, capital, or local buy-in?
