What would happen to the Bitcoin network if the internet connection between continents sever temporarily?

Let’s say the internet connection will be (intentionally or unintentionally) cutoff between USA/Europe/Asia.

There would be 3 different Bitcoin networks, where each network has its own nodes and miners.

Each network’s miners will keep on mining the blocks of its own network and creating a new chain.

During the time the internet connection is cutoff, each network will have its own transactions made.

After a certain time, lets say a week, the internet connection between the continents resumes.

Then all of other networks will default on the network with the longest chain.

That means that all the transactions that were made in the other networks during that time don’t have any record on the main chain.

Isn’t that a huge risk to the bitcoin network as a trusted global ledger?

Shouldn’t we prepare some type of a conduct protocol in case something like this happens?

Do we, as the bitcoin protocol network participants, have any way to secure the network in more global ways, connecting the continents, perhaps with P2P satellite connections, or any other way, sharing the longest chain with each other, to make sure we keep all continents connected to the same longest chain, and preventing multiple chains from happening?


Thank you

  1. I am confident the network would still be able to communicate and be on the same chain during, say, large scale systemic exploitation / manipulation of internet access via ISPs, Government censorship, One World Government influence, etc.

    Still a lot of trust involved, even w/ something like StarLink, Blockstream, etc. There are some efforts to globally decentralize internet access (thus removing ISPs or any potential corporate or Gov. attack vectors in the future) can’t recall the name(s) but essentially you buy a little solar powered kit which includes a small satellite uplink / terminal to which you can connect to and broadcast transactions.

    In any event I am glad you are thinking about this because I do believe this will be part of future systemic attacks, at whatever vulnerabilities exist now or emerge, but once again I am 98% confident that the real world physical cost would be far too prohibitive to be effective or even feasible to “brute force” separate the chains, via targeted connection/signal broadcasting attacks, to create various continental chain splits for the inferior/subordinate hashing power regions and thus, BTCEU, BTCUS, BTCAF, BTCASIA etc etc.

    Finally there is the scenario of electromagnetic pulse attack to knock out connection / infrastructure but if / when we get to that point, and hopefully not, the security of bits and transacting value will likely take the backseat to a reversion to the basics (food, water, barter with physical things /commodity money, and of course radiation equipment / therapy, etc until such time that humans rebuild and get back online,

  2. Very interesting question. I don’t have the answer and I’m waiting for the community to offer some insight.

    For the time being the community seems to be evading the question by saying that it’s either unlikely or it can be bypassed by satellites.

  3. I’d assume any reasonable sized mining operation has backup satellite connections. While it’s true I’m assuming here, but I ask you, can you imagine multi-million dollar operations not having thought of backup communications?

    Second if this were a real situation and let’s say even satellites were out. I’d recommend not worrying about bitcoin and trying to find a bunker to hide from the nukes, or worse.
