The Crypto Currency Address Generator,

The proposed "Open Source" software project would "Root, Wipe, and Install its software on an older android phone. making a hand held portable simple offline device crippling the previous devices hardware so it is no longer capable of transmitting data except through screen display.

The User With this newly created device and programming now "generates offline BTC wallet addresses" complete with private keys. The user with previously acquired BTC, can then transfer their funds from an online exchange, website, ATM, personal one on one transaction, etc. into cold storage through the device onto small secure encrypted backup SD cards. The user can also quickly perform transfers to online exchanges from said sd card backups using said portable device as well, This device has been designed entirely for the end users security and privacy and ease of use in mind.

- The Open Source Software Description - User first generates random addresses with new totally offline cold storage device

Created addresses are then stored in a hierarchical file system on an SD card, The Cold Storage Device on the left shows a list of generated Bitcoin addresses, The Generator on the right shows The filing system of folders they are stored in.

Addresses after created offline can then be converted to paper wallet format later to be printed to offline printer if user so wishes via SD card file.

Also user can take pictures with the pre existing devices offline camera for paper wallet Image and background creation, software for paper wallets could also include templates and themes.

Previous Personal Use and Further Description

In my Bitcoin adventures by using this device, I have never needed to use a PC or Laptop, to create or share any of my BTC or ETH addresses.

I have never used a PC or laptop to place Bitcoin in total offline cold storage. In my entire blockchain experience I have never had to find or use a PC or Laptop, This new device is totally hand held portable and stand alone when used in tandem with users cell phone.

Concerning security, In order to stop prior hardware data transmission of the original device, The software program proposed would be a simple first Linux based root access of the older android phone to erase its programming. Then A following basic install in which the final new software program has no awareness of the existing hardwares data transmitting capabilities. Open source is needed to protect this devices security in this manner.

Further description –

A simple very basic Linux GUI would also be necessary to help user for the best ease of use while the program manages file system and background processes such as spreadsheets for Book keeping, tax records, ledger books, on SD card if user so desired, If user does not need these applications they can opt out,

This GUI would be very simple and basic when compared to a full blown linux pc distro, and designed solely for crypto currency storage printing and online transfer from the proposed device

A product model has been built, used, and beta tested for over a month and a half now, Its progress has been recorded on the BTC and ETH blockchains themselves. It can securely generate and store BTC and ETH addresses offline flawlessly and securely so far to date without any need of a PC.

After generating and storing addresses, the device can easily access multiple online exchanges to transfer funds to and from cold storage SD cards via devices "airgapped" Camera/Scanner and QR screen display. it works cross platform with most exchanges in this matter without need for proprietary online software integration

If anyone in the open source community would like to take this project on and would like input from a beta user level, i would love to help out in a small way on this proposed project. I can see some details that would be nice in which I haven't mentioned. And some ideas that would help the user with security and ease of use. I do not code, but have been solely using Linux as a PC laptop operating system since 1998. And have somehow put this device together using android apps and open source software. And then used it extensively.

Why Linux

I'm not sure, but I heard Android phones have a Linux kernel and you can gain root access to its software. This is a great help in security, as Linux itself is known for user security.

Why open source

Because of the user confidence in knowing whats inside it for their personal security and privacy, Also So the individual user can modify its entire programming through innovation to suit their own personal needs for private portable offline storage,

Brent L. McNealy, I am looking for a team of programmers and developers to help this become a reality, thank you
