The short answer is no—neither King Haakon VIII nor any single ruler, government, or institution on Earth can simply «turn off» Bitcoin.

Even if His Majesty desired to do so, he would run into two insurmountable walls: technical reality and constitutional reality.

1. The Technical Reality: Why Bitcoin Cannot Be Turned Off

Bitcoin operates as a decentralized, peer-to-peer network distributed across tens of thousands of independent nodes and miners running across every continent.

To «turn off» Bitcoin, a government or sovereign would have to:

• Shut Down the Global Internet Simultaneously: As long as any two computers anywhere on Earth have an internet connection—or even a satellite link, radio frequency, or mesh network—they can transmit Bitcoin blocks and transactions.
• Control a Global Consensus: Even if a country completely disconnected its own power grid and telecom networks, the rest of the worldwide Bitcoin network would continue mining and validating blocks without interruption.
• Overpower the Network (51% Attack): To alter or halt the chain, someone would need to acquire more hash rate (computational power) than the rest of the world combined. Even a sovereign nation’s state resources cannot easily seize or out-compute the global network of specialized ASIC miners.

If Norway were to ban Bitcoin mining or force local ISPs to block Bitcoin port traffic, it would only stop operations within Norwegian borders. The Bitcoin network itself would simply re-route traffic and keep running.

2. The Constitutional Reality: The Role of the Norwegian Monarch

Under the Constitution of Norway (Kongeriket Norges Grunnlov):

• Constitutional Monarchy: King Haakon VIII acts as the formal head of state, but political and executive power resides with the elected government led by the Prime Minister and the parliament (Stortinget).
• No Absolute Dictatorship: The King cannot unilaterally issue executive decrees to shut down industries, block websites, or confiscate assets without legislation passed by the Stortinget and implemented through standard democratic and judicial channels.

What Could a Sovereign Nation Actually Do?

While King Haakon VIII or the Norwegian state cannot turn off the protocol, a sovereign country can influence how Bitcoin interacts with its domestic economy through policy:

1. Grid Restrictions / Mining Bans: Norway relies heavily on cheap, renewable hydroelectricity. The government could restrict data centers or Bitcoin miners from accessing the electrical grid (a policy that has been debated in Nordic parliaments before).
2. Banking Bottlenecks: The state can instruct the central bank (Norges Bank) and financial regulators to restrict commercial banks from facilitating fiat-to-crypto exchanges.
3. Taxation and Compliance: Enforcing strict wealth taxes, capital gains reporting, and MiCA-aligned regulations makes holding or using Bitcoin legally burdensome within the country.

Reint Jelger: But if all the Belgiums would come together, they could turn Bitcoin off right?

Gemini: Not even if all 11.8 million Belgians stood together in perfect unity could they turn Bitcoin off.

Even if the entire population of Belgium decided to completely erase Bitcoin, they would run into the exact same insurmountable wall of network architecture: Belgium only controls Belgian territory.

What Happens if All of Belgium Decides to «Kill» Bitcoin?

If every Belgian citizen, the federal government in Brussels, the regional governments of Flanders and Wallonia, and every local Belgian telecom company united against Bitcoin, here is what they could actually do:

1. Unplug Every Belgian Node: They could disconnect all ~100 to 200 Bitcoin full nodes running inside Belgium.
2. Shut Down Local Mining: Any Belgian ASIC miners or home mining rigs would be powered off.
3. Block IP Ports at Belnet/Proximus/Telenet: Belgian Internet Service Providers could block standard Bitcoin peer-to-peer traffic (Port 8333).
4. Ban All Financial Chokepoints: KBC, ING Belgium, and BNP Paribas Fortis could freeze any bank transfer to or from crypto exchanges.

The Network’s Response:

The moment Belgium disconnects:

• The thousands of Bitcoin nodes in the Netherlands, Germany, France, Japan, Brazil, and the US don’t miss a single beat.
• The block timer (~10 minutes) continues processing transactions seamlessly across the rest of the planet.
• To the Bitcoin protocol, Belgium simply disappeared off the map, much like a house losing power during a storm. The ledger keeps updating elsewhere.

The «51% Attack» Scenario: Could Belgium Hash-Power It Down?

To actively disrupt or halt the Bitcoin network rather than just banning it locally, you don’t just ban nodes—you have to perform a 51% Hashrate Attack. This means controlling more specialized computing power than the rest of the world combined.

• The Hardware Wall: All the supercomputers and servers currently sitting in Brussels, Leuven, and Ghent combined do not speak the algorithm (SHA-256) needed to mine Bitcoin at scale. They run general CPU/GPU code, whereas Bitcoin requires trillions of dedicated ASIC microchips.
• The Power Wall: Even if Belgium spent billions to purchase 50%+ of the world’s global ASIC fleet, powering that fleet would require dozens of gigawatts of continuous electricity—far exceeding Belgium’s total national electrical grid capacity.

The Real World Limit: Jurisdictional Boundaries

This highlights the fundamental nature of decentralized, open-source protocols like Bitcoin, BitTorrent, or TCP/IP:

A nation-state—no matter how unified—only has sovereign jurisdiction over its physical land, power lines, and citizens.

Belgium could make Bitcoin illegal within its borders, effectively driving it underground or forcing Belgian users to use satellite links (like Starlink) and VPNs. But to turn Bitcoin off, Belgium would have to conquer and shut down the internet and power grids of every single country on Earth simultaneously.
