## Motivation
|
||
|
|
|
||
|
|
Nowadays, there are many web and mobile apps providing bitcoin and lightning wallets
|
||
|
|
functionality. They are mostly known as [SPV], Simplified Payment Verification clients
|
||
|
|
which connect to a [full node]. Likewise, [hardware wallets] also typically require
|
||
|
|
a companion app which in turn connects to a full node run by someone else.
|
||
|
|
|
||
|
|
Historically, bitcoin - and especially lightning - nodes have been run by
|
||
|
|
organizations and people with knowledge in cryptography, system networks and
|
||
|
|
software engineering.
|
||
|
|
|
||
|
|
Nakamochi takes on the challenge to make such nodes usable to a broader audience.
|
||
|
|
Just like a coffee maker or a microwave oven, we believe anyone should be able
|
||
|
|
to run a node at home and reach 100% privacy and independence. Running one's own
|
||
|
|
full node also helps the whole Bitcoin network to remain decentralized.

## The name
|
||
|
|
|
||
|
|
The name "nakamochi" comes from putting together [Satoshi Nakamoto], the founder
|
||
|
|
of Bitcoin, and a
|
||
|
|
[famous Japanese handheld digital pet](https://en.wikipedia.org/wiki/Tamagotchi)
|
||
|
|
to emphasize personal, self-hosting.
|
||
|

## Editions
|
||
|
|
|
||
|
|
The following editions are listed in an order of increasing ease of use.
|
||
|
|
It is always a trade-off between the costs and effort oneself has to put
|
||
|
|
in and the trust into the manufacturing companies and their supply chain.

|
||
|
|
|
||
|
|
All the editions have something in common: the touch screen user interface and
|
||
|
|
automated system updates. Even at a high level of distrust one can still benefit
|
||
|
|
from the open source software and, equally important, system updates.

The [DIY version](https://git.qcode.ch/nakamochi/3d#diy-version-fff) is designed using
|
||
|
|
only off-the-shelf hardware components and 3D printed parts. It is a running system
|
||
|
|
and you can source and even replace the hardware. Everything is open source and freely
|
||
|
|
accessible for everyone. You can of course buy the whole kit from us to make things easier.
|
||
|
|
Enjoy checking out the source code, CAD designs and schematics. You can tinker here, just
|
||
|
|
be sure that the device still works after that.

If you want to profit from some product engineering but still want to use
|
||
|
|
off-the-shelf components, we recommend the DIY+ version. As the name tells,
|
||
|
|
the "plus" in this version improves some characteristics of the device.
|
||
|
|
|
||
|
|
For example, the previous DIY version may suffer from overheating in certain
|
||
|
|
conditions. This edition improves heat dissipation while keeping the device
|
||
|
|
completely silent, fanless.
|
||
|
|
|
||
|
|
However, this edition still requires technical knowledge in CNC machining
|
||
|
|
and 3D printing.

If you are mostly interested in the freedom of the Bitcoin Standard, helping
|
||
|
|
the Bitcon network to remain decentralized, and want a device that just works
|
||
|
|
without a DIY-like technical knowledge in hardware design and software engineering,
|
||
|
|
the PRO edition is the one for you.
|
||
|
|
|
||
|
|
We are taking all the knowledge and learnings from the DIY versions and designing
|
||
|
|
most of the parts ourselves here: from mechanical parts and enclosure to PCBs for
|
||
|
|
an optimal device solution where hardware and software work very well together.
|
||
|
|
All of the work is open source.
|
||
|
|
|
||
|
|
The PRO edition is still work-in-progress.
