Change the home screen image on your bitcoin TREZOR

You could change the home screen of your bitcoin TREZOR with a few simple steps. I’ve tested this on a Debian 8, so probably will work for other Debian-based distros (Ubuntu, LMDE,…)

 

The image has to be a 128×64 black and white .PNG file. This is mine.

Install dependencies with

sudo apt-get install git python python-dev python-setuptools cython libusb.1.0-0-dev libudev-dev

Get the python command line tool

git clone https://github.com/trezor/python-trezor.git

Change to the directory

cd python-trezor

 

Download and install some dependencies

sudo python setup.py install

 

Set the homescreen

sudo python cmdtr.py set_homescreen -f /path/to/your/image.png

 

I suggest you disable your TREZOR’s PIN before changing the image and re-enable it later as the process will be easier. To change your PIN, go to mytrezor.com, click on your device name (not your accounts) and the “Advanced” tab. Images with most of them white could be too bright for use as homescreen, I would suggest using mostly black images.

Decentralizing bitcoin itself

It has been lately some debate about bitcoin scalability. In my opinion, we’re looking at the problem from the wrong side, of course it’d be great if bitcoin is use worldwide and is the only currency, but what about decentralizing bitcoin? Not having one, but multiple “bitcoin”? I’m talking about side-chains. Sidechains allows you to have alt-coins “backed” by BTC with different features, but what if we use a sidechains with no new features? 1:1 backed with bitcoins? What if instead of  bitcoin, we have spain-bitcoin, france-bitcoin, japan-bitcoin,… if some of them grows too much, divide it.

 

We’ll have a worldwide common currency, bitcoin, at any time you could cheaply exchange to and from bitcoin, and then we’ll have localized-bitcoin with fewer fees and smallers networks and blockchain. I would guess that most people don’t need to exchange their currency from one to another. Travelers and online shopper may, but it’s cheap, fast* and simple.
