Reviving your old smartphone, support the network with a bitcoin node

[Troytech]

I would love to do a lil-intro on what a bitcoin node is before I dive into the main context of the topic incase a newbie is reading.

What are bitcoin nodes and what are they important to the network

Bitcoin nodes are computer or devices that run a bitcoin software and store a copy of the entire bitcoin blockchain, which is the decentralized digital ledger that records all bitcoin transactions. Nodes are essential to the bitcoin network cause they:

Verify Transaction: nodes ensure that the same bitcoin is not spent twice theyby checking the validity of a transaction, if you have transferred a bitcoin to someone before you could see that the transaction is being processed or some apps would tell you validating transaction, its the node that is responsible for oder in the bitcoin network.

Nodes also ensure transparency by storing a copy of the entire blockchain which helps improve accuracy and integrity of the network.

Nodes are a key factor that helps synchronise wallets with network allowing bitcoin to sent and received between one another.

In conclusion nodes helps maintain decentralization, ensure security, facilitate network scalability etc., bitcoin nodes are literally the backbone of the entire network and they are the main reason the network remains functional and smooth.

Introducing the idea of repurposing smartphones as a bitcoin node

In our current time a lot of people are using the bitcoin network regularly which calls for a need for more nodes, smartphones get outdated easily and most phones don't last more than 2 years as they life span and would get dumped or thrown away, instead of letting old smartphone collect the dust or trashing them away you can repurpose them into a bitcoin node and let them leave the rest of their days useful to the bitcoin network. And moreover there are very easy to come by and the set isnt complex although it might need to few extra components that you can find around.

Old smartphones have the necessary hardware and storage capacity to run a Bitcoin node, making them an ideal candidate for repurposing. By installing Bitcoin node software on these devices, we can create a decentralized network of nodes that verify and relay transactions, ensuring the integrity and security of the Bitcoin blockchain.

How to setup and run a bitcoin node on a smartphone.

Requirements

-An old smartphone android or ios( although smasung seems to be the best)
- A microsd card at least 128gb for a pruned node and 1terabit external harddrive to run a full node.
- an otg adapter for android or a lightning to USB camera adapter for ios
- a steady power source( power Bank)
- Internet connection WiFi

Software
-termux and then install bitcoin core(abc)

Or mynode for ios

Setup

1. Prepare your phone:
    - Make sure your phone is fully charged and has enough storage space.
    - Enable Developer Options and USB debugging (for Android).
    - Trust the computer (if prompted) when connecting your phone to a computer.
 - Insert the microSD card into your phone.
    - Format the microSD card as internal storage (for Android) or use the "Store Bitcoin blockchain on external storage" option (for iOS).
 - Connect your phone to a Wi-Fi network or use a USB Ethernet adapter for a wired connection.
 - Connect your phone to a power source to keep it running continuously.
2. Install Bitcoin Core (Android) or MyNode (iOS):
    - Download and install Bitcoin Core from the tremux or andronix from playstore
    -  Termux is a Linux terminal emulator for Android. It will provide the emulation environment for Ubuntu Linux
    - After installing Termux on the phone, you must install Ubuntu on the emulator. All you have to do is copy and paste this code on Termux

pkg upgrade && termux-setup-storage && curl https://raw.githubusercontent.com/AndronixApp/AndronixOrigin/master/repo-fix.sh > repo.sh && chmod +x repo.sh && bash repo.sh && pkg update -y && pkg install wget curl proot tar -y && wget https://bitbrasil.com.br/sh/ubuntu20.sh -O ubuntu20.sh && chmod +x ubuntu20.sh && bash ubuntu20.sh

    - In the same way that Ubuntu was installed on Termux, install Bitcoin Core on Ubuntu by copying and pasting the following command and executing it on Termux.

apt-get update && apt-get upgrade -y && apt install curl -y && curl https://bitbrasil.com.br/sh/install-full-node.sh | sh

This code will install the Bitcoin software on the mobile phone and store the blockchain data on the external drive.


3. *Configure the node:
    - Set up the node as a "Full Node" or "Pruned Node" (depending on your storage capacity).
    - Configure the node to connect to the Bitcoin network.

    - Regularly update the node software and restart the node if needed.

Old smartphones have the necessary hardware and storage capacity to run a Bitcoin node

Old smartphones barely have 100 GB in storage. If your goal is to help the network in terms of bandwidth, it's required to store and transfer the entire blockchain, which is far bigger in size than that.

By installing Bitcoin node software on these devices, we can create a decentralized network of nodes that verify and relay transactions, ensuring the integrity and security of the Bitcoin blockchain.

There is no point in doing that, though, unless the smartphone owner wants to run a node for personal gain (privacy and security of their funds), and is incapable of running one in a PC. Installing and running Bitcoin Core on your smartphone is not easy to setup, and questionably secure.

There are over 50,000 nodes running. The network is pretty good in terms of bandwidth, already.

Locally, storage might not be the problem because pruning, and it's cheap. But for old smartphones, processing power - probably yes. During IBD, the smartphone might start slowing down when it starts validating data from that time when there was more network usage. It probably can't keep up with the network.

Smartphones can't reach up to computers in the aspect of durability in running a node, but there sure are better soending the rest of their lifespan running a bitcoin node than biting the dust sitting somewhere in your house, I just bought a power Bank and I plan on doing this myself to join on the run a node challenge in the beginners and help section, I wonder if that is allowed.

I'm going to disagree with you the guy you copied this from on many points:

Nodes also ensure transparency by storing a copy of the entire blockchain which helps improve accuracy and integrity of the network.

This doesn't mean anything if you don't use a wallet on your node.

In our current time a lot of people are using the bitcoin network regularly which calls for a need for more nodes

My full node only used a few percent of it's allowed bandwidth. That makes me believe there is no shortage of bandwidth in the Bitcoin network.

smartphones get outdated easily and most phones don't last more than 2 years as they life span and would get dumped or thrown away

Unless you drop them, most phones can last a lot longer. A new one has almost exactly the same features, but you'll waste hours setting it up. So don't buy a new one every 2 years, save yourself the time, and you could even buy Bitcoin with the money you saved.

the set isnt complex

So where are the pictures of your own phone that runs Bitcoin Core?

1terabit external harddrive
- a steady power source( power Bank)

First, a battery pack isn't a stable power source. Second: how are you going to connect an external hard drive and a power connector at the same time?

Did you seriously just copy all this, without using quote tags, to make it look like you wrote this just to earn Merit? Welcome to my ignore list!

Where are source, discussion or data which can prove those statement?

Requirements

-An old smartphone android or ios( although smasung seems to be the best)
- A microsd card at least 128gb for a pruned node and 1terabit external harddrive to run a full node.

You said old smartphone have enough storage, but then mention microsd or external harddrive as requirement. It's also worth to mention you could use microsd with smaller capacity.

Or mynode for ios

Neither you or link sources what exactly is mynode or how we can obtain it. Do you mind briefly answer those question?

3. *Configure the node:
    - Set up the node as a "Full Node" or "Pruned Node" (depending on your storage capacity).
    - Configure the node to connect to the Bitcoin network.

Bitcoin Core automatically try connect to Bitcoin network, so there's no need to configure it manually. In addition, what are

I'm really sorry about that information, it's wrong, I watched a YouTube video on how to run bitcoin node on ios and that what i got, I didn't bother to confirm the information since I don't have a ios device, I'll lock this thread or ask modertors to delete it, but I'll give pictures on my own node connection on android.
