Bitcoin requires an internet connection for transactions and ownership. But what if your internet provider goes down? How can you access and use your Bitcoin in such situations? Are there ways to reduce reliance on traditional internet service providers?

Another option is to use satellite communications. But it can also be blocked if necessary.

Can you use satellite communication to connect your Bitcoin node to the internet?
reply
Absolutely. One example is Blockstream Satellite
Blockstream Satellite broadcasts the Bitcoin blockchain to the entire planet via satellite, reducing Bitcoin’s dependency on internet access. Everyone in the world now has an opportunity to use Bitcoin.
You can also use other companies like Iridium or Starlink to have Internet through satellite.
Or even pigeons under RFC 1149 :)
On 28 April 2001, IPoAC was implemented by the Bergen Linux user group, under the name CPIP (for Carrier Pigeon Internet Protocol).[4] They sent nine packets over a distance of approximately 5 km (3 mi), each carried by an individual pigeon and containing one ping (ICMP echo request), and received four responses.

Same as anything. Redundancy. Phone as a hotspot. Learn how to do tethering. Use an actual hotspot device. Move around using a wifi access over VPN provider like Mullvad/iVPN or Tor.

I was wondering it too.

A good multi-wan router will allow you to connect multiple access methods to the Internet:
  • Land line: Fiber, Cable, DSL, dialup
  • Cellular: GPRS, GSM, 5G, 4G, 3G
  • Satellite: Starlink, Viasat, HughesNet
  • Fixed wireless broadband: Radio
  • Ethernet over Power Line
For redundancy, try using 3 separate access methods: Fiber, GPRS, and Satellite e.g. These can be bonded for increased bandwidth, and configured to failover, so that if one or two points go down, the third will still route. There are many other methods to access the Internet, the above lists just a few fairly common ways.
Maintaining electricity is also important, so beyond your wired lines, you want solar/wind and a diesel generator placed above any potential flood line. Because it is precisely during a flood when power goes out, but you need to keep your Internet running. Even a bicycle powered generator with battery backup can kick out 50-100 watts and keep the router and a minimal node running.
Hope for the best, but prepare for the worst.

Otherwise, it depends on the problem to be solved. If your residential cablemodem internet goes down, for example, you might have mobile data as an option. If both go down, you might have somewhere with a fiber connection. Now if all of the internet in your area goes down, you have bigger problems than using bitcoin.

I think Elon will give access to all Bitcoiner for his starlink! 100000 sats 100000 GB data...👊

You could always use elons musks service. They use it in Ukraine.

I'll be depending on Starlink.

I think many people will be depending on starlink. There is no real competition at the moment.
