Topic: I'm Thinking of Bitcoin Blockchain Accessible Without Internet (Read 856 times)

Even if we assume that it is impossible to reach their cryptocurrency funds that are somehow at a distance and without the Internet, it is quite realistic to implement the idea of ​​communication using SMS notifications.  Only I am sure that in this case all the possible security of the cryptocurrency and personal funds of the user is violated.  I believe that this idea is, in principle, doomed to failure.  If we are talking about high technology, then it’s ridiculous to talk about places where there is no Internet.

I think it is difficult to do since we need the internet to access a certain bitcoin wallet like coinbase.com. In order to access the database or the website they have, we are going to need a internet for sure.
Most likely I think the transactions surely need an internet connection to be made in blockchain and even accessing bitcoin wallet need an internet connection so I don't think it is going to be possible this day. But I believed it is possible in some ways.

The entireity of the whole blockchain made initially to digitalize currency and to replace the existing traditional currency and the word "digitalize" means it's not so far from internet or rather dependant to internet so it just doesn't make sense to be accessible without internet except there's another way which is utilizing SMS.

Most likely, you just need access to the Internet, because the blockchain cannot open without the existence of the Internet. There is a local network, but they’ve got to it and used the local network of bitcoin. There are no other ways, except that they did not invent a connection to the blockchain chain, without access to the Internet.

I think internet is the main source to transact bitcoin and crypto activitiies. Its basically an online based technology and we cannot deny it for now. Having a connection with blockchain without the internet is somehow complicated. We need internet as we transact and so with those who will receive it. Internet connection today is most likely one of our basic needs.

I see, it's quite ironic to say it doesn't need an internet but a stable network. In the first place, network will run through the world because of Internet, and Internet is the network itself. I don't think there's any more reason to consider having a bitcoin network without an internet as it is the fundamental requirement to connect the people around the world. If we are to think of possible ways, was it infrared? Microwave? no, nothing can be more suitable aside from the internet.

Bitcoin blockchain doesn't need internet but it needs a stable network. We are using the internet for Bitcoin as it is the best network solution today. It's possible that one day Bitcoin will have it's own network with several connection possibilities and that the internet will be a side network that is connected to that main network.

Until now, we still have no way to access blockchain and bitcoin without internet, internet is the source of this technology, without internet, this technology will not work, and I don't understand why some people want to get involved in bitcoin without the internet. Agree that this may help us more convenient in the transaction process but this idea does not seem so suitable when bitcoin and blockchain are high technologies, the internet is necessary, and now that internet coverage is global, we don't need to worry about where we work without internet.

Still not available using bitcoin without internet, almost exchange market need good internet to browsing and sending bitcoin. For trader need super faster internet access because with lower speed of internet they can miss chance with selling and buying altcoin trading, when I want trade I check how faster my internet first, if internet look slow I can't trade for altcoin and bitcoin.

The way some people reason is quite strange . Blockchain is based on the web and cryptocurrency is an Internet money, how exactly do you expect to be making use of something that's meant to be used with an Internet connection offline?

Unless you plan to make use of a wallet that is stored on your device and then look for a way to share some bits from your device, but that's not even possible. This doesn't make any sense, because it's not possible and by the way I don't think there will ever be a need for someone to use cryptocurrency in a place where there is no Internet connection at all.

I have not been able to think of other ways except to only use paperwallets between users.

But this is also not an active solution because it still requires an online reedem process. Blockstream can be effective if used with networks with each other, but not all users use it and still rely on third parties. We cannot continue to be exclusive and must adapt to what can be used until now.

With internet IP are attributed by a centralized or hierachised organisation, but there should be ways to do without. The only thing really needed is to identify a node to have directed message like request over a connection that would be directed at one node to have a potentially better distribution of requests or such. Using asymetric cryptography can prove the node answering has the private key that identify the previous messages, and it can be used to have connection-like behavior with several nodes without needing an IP To distiguish them.

If you don't have electricity, you can't use a credit card. If you don't have electricity, you can't withdraw money from the cash machine. No electricity, no internet. You can't do the things I just said again. I expect the internet to become cheaper and more widespread in the near future. Water is very common and cheap. The Internet will be very common and cheap. Bitcoin will be welcoming us for a very long time;)

This is one of the shortcomings of transactions using bitcoin, although an internet connection is not absolutely necessary as mentioned above by using blockstream satellite or radio waves, all you need to set the things up. Even if two parties transact using bitcoin without internet connection using physical bitcoin, the seller has to ensure that the coins really have bitcoin private key inside, which needs the internet.

And how profitable is your option if you use it directly on cryptography?

I don't think this will be possible since the Bitcoin block chain Technology was built on the basis of internet for accessibility, investment ,trading .....etc all with the use of internet. It then mean that without internet there would not be assess to your Bitcoin wallet. 

I already thought about that and i think it could work.

If you break down internet what you have is low level protocols like ip, tcp/udp, which is useless in case of bitcoin because the protocol doesnt dépend on IP address to identify users, and its a message based protocol so it should work on connection-less protocol like udp or even simpler, and the blockchain protocol already allow To check data integrity so it in part redundant with lower layers, and all packets are supposed To be transmitted to all nodes indiscriminally, so there not even a real need for ip layer.

Other part of internet is DNS server, but its mostly used To identify a particular machine as being controlled by the person owning the domain, and blockchain are trustless so doesnt require dns either. All nodes are supposed To have the same data minus few last blocks. Maybe there could be reason To want dns for initial download especially for staking coins to avoid sybil attack.

To me you could perfectly have a system of datagram transmission over very simple radio protocol, and you just need To be in range of at least one node or a few in order To keep synchronized, and you would only need To have a few nodes that have internet for trans continental transactions.

It might require some change to the bitcoin protocol as it is now To be efficient in block propagation and bitcoin protocol as it is still rely on internet To identify seed nodes and have certain part that depend on IP address like for banning or identifying nodes but its not critical and something based directly on cryptography could be used instead.

It would be really hard to establish a bitcoin blockchain if no internet connection is involved, why? Simply because bitcoin is decentralized and it requires an internet connection in order to run the system. And if someone can develop bitcoin or blockchain technology as an access even though without any internet connection then it would be really hard because just like what I have been said bitcoin needs internet to be regulated, because if this internet loss then it would be really a hard problem for us to get some coins or tokens. So the sayings that if you want to regulate bitcoin then you must establish first a very good internet connection.

You can ask a friend you can trust an affordable Internet network is easier and better to just call a friend who is connected to the Internet and provide your data to allow your friends to help you order the withdrawal process in accordance with the number you requested. This means that the best way to not get more complicated.

Yep. Considering that in order to use the cell towers across the globe or even if you just narrow it down locally you would come to a realization that you need the government's permission to provide internet to the users which is the case of the telecommunication companies you have in your country so having a decentralized internet connection as what the OP is proposing is very unrealistic and would not really happen though I think we don't really need to have such a thing or project if you may call it because there are many ways to mask your internet browsing if you don't want any third party snooping you around.
