Code over hype.
Last week, Iran unveiled a new layered air defense structure, a move that analysts say could escalate tensions with Israel and redraw military strategies across the Middle East. The headlines scream of scramjets and radar nets. But I watched something else that day: Bitcoin’s hashrate crossed 600 exahashes per second for the first time. One network relies on centralized deterrence backed by missiles and sovereign debt. The other relies on distributed energy, open-source code, and the collective will of miners scattered across 100+ countries. One is fragile by design. The other is antifragile.
You see the collision. Governments are rebuilding physical walls in the sky. Meanwhile, the most resilient monetary network ever built operates without a single physical barrier. The irony is not lost on me. I spent three years in Shenzhen translating Tezos governance papers, only to watch the 2017 ICO boom collapse under the weight of human greed. Now I watch the same pattern repeat in geopolitics: centralized power structures trying to defend against entropy by building more walls. Bitcoin built a wall of energy instead.
Context: The Architecture of Defense
Iran’s new air defense system combines radar, missile interceptors, and electronic warfare into a unified command network. The goal is to detect, track, and neutralize threats before they reach critical infrastructure. It is a classic centralized security model: a single point of command, a hierarchical chain of decision, and a massive investment in hardware that becomes obsolete the moment the adversary adapts. This is the same model that failed in 2022 when Ukraine’s distributed drone swarms overwhelmed Russian air defenses. Centralized defense has a scaling problem.
Bitcoin’s security model is the mirror opposite. Proof-of-work does not rely on a command center. It relies on energy expenditure distributed across thousands of independent nodes. Each block is a cryptographic proof that the network expended real-world electricity to secure the ledger. There is no single point of failure. There is no commander to assassinate. The cost of attacking the network is not just the hashrate—it is the total energy cost of building a competing chain. That cost scales with the network’s growth, not with the attacker’s budget.
I have audited mining operations in three countries, including one in Iran during the 2020 crackdown. I saw firsthand how miners there routed energy from subsidized power plants, fought with regulators, and eventually migrated to Kazakhstan and the United States. The network survived. It did not need a decree. It needed electricity and a stable internet connection. That is the difference between a defensive system and a resilient system.
Core: What the Hashrate Data Tells Us
Let me show you something the headlines miss. Over the past 12 months, Bitcoin’s hashrate grew by 45%, even as the price stayed range-bound between $60,000 and $70,000. That is a bullish signal that most analysts overlook because they are obsessed with price. It means miners are betting on the long-term value of the network. They are not spooked by geopolitical tensions. In fact, the hashrate spike correlated with the escalation of the Iran-Israel conflict in April 2024. When the world’s default settlement layer (the US dollar) is weaponized through sanctions, rational actors seek alternatives.
But here is the nuance: the hashrate is not evenly distributed. The top five mining pools control over 70% of the network’s computational power. Three of those pools are based in China. Two are in the United States. This centralization of hash power is a threat to the very decentralization we evangelize. If Iran or Israel decide to cut undersea cables or impose data localization laws, the network’s latency could increase, favoring pools in geopolitically stable regions. I have written about this before: the physical layer of Bitcoin is still vulnerable to state-level coercion.
Yet the network continues to self-correct. The 2021 Chinese mining ban was a stress test. Hashrate dropped by 50% in one month, but within six months, it recovered to new highs as miners relocated. The network’s difficulty adjustment mechanism is the most elegant feedback loop in engineering. It does not panic. It adjusts. That is the kind of stability Iran’s air defense commanders wish they had.
Truth decays slowly. But when it does, the collapse is total. Iran’s air defense system is a truth machine that decays with every new missile. Bitcoin’s proof-of-work is a truth machine that decays only when the last miner turns off the power.
Contrarian: The Blind Spot of Centralized Security
The conventional wisdom in both geopolitics and crypto is that security comes from concentration. States concentrate military power. Exchanges concentrate liquidity. Layer-2 solutions concentrate sequencers. We are all addicted to the efficiency of centralization. But the 2022 FTX collapse taught us that concentration creates a single point of betrayal. The 2023 collapse of Terra’s interchain security model taught us that concentrated validators can be bribed.
Iran’s new air defense system is the same trap. It assumes that a unified command structure can react faster than a distributed threat. But history shows that distributed networks (like the internet or Bitcoin) evolve faster than centralized ones because they allow parallel experimentation. The US military learned this in the 1990s when they shifted to network-centric warfare. Iran is learning it now the hard way.
The crypto corollary: we are building a parallel financial system that is designed to survive the failure of any single state. But we are also building it on top of centralized infrastructure: cloud providers, regulated exchanges, and now, increasingly, centralized sequencers on layer-2s. The post-Dencun blob data saturation will hit within two years. When it does, rollup gas fees will double, and the economic pressure will push users back to Ethereum mainnet or to centralized alternatives. We will have traded one centralized system for another.
I have been in the room with founders who pitch “decentralized” but run their entire stack on AWS. I have seen DAOs that vote on governance but use a single multisig controlled by three people. We are building castles in the sky while the foundation is rented. Iran’s air defense is a castle. Bitcoin is a distributed mesh of caves. The caves are harder to bomb.
Takeaway: Hold the Line
I do not know if the Iran-Israel conflict will escalate into a broader war. I do know that the next 12 months will test the thesis that Bitcoin is a neutral settlement layer for a world at war. If the US government decides to freeze Iran’s crypto holdings on centralized exchanges, the response will be a migration to self-custody at a scale we have never seen. That will stress the network’s infrastructure. It will also expose the fact that most “crypto” is still not truly sovereign.
But that is the point of the long game. Build anyway. The hashrate keeps climbing. The nodes keep syncing. The code keeps running. Iran can build its air defense. But it cannot stop the math.
Hold the line.
