tagline: "a device for complete privacy and financial independence leveraging bitcoin and lightning networks"
|

## 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
|
|
|
|
|
|
We are focusing on two editions. One for tinkeres and people with
|
|
|
technical knowledge. The other is a "plug-and-play" device, like a
|
|
|
coffee maker.
|
|
|
|
|
|
<div class="text-media-card">
|
|
|
<div class="card-text">
|
|
|
|
|
|
The editions have something in common: the touch screen user interface
|
|
|
and system updates. Naturally, everything is open source, including
|
|
|
electronics and mechanical parts we designed ourselves.

### NERD

<div class="text-media-card">

|
|
|
|
|
|
The NERD edition is designed using only off-the-shelf electronics components,
|
|
|
3D-printed and CNC-milled mechanical parts. It is a running system and you can
|
|
|
source and even replace the hardware. Everything is open source and freely
|
|
|
accessible for everyone. Here you profit from some product engineering.
|
|
|
It improves heat dissipation while keeping the device completely silent, fanless.
|
|
|
|
|
|
You can of course buy the whole kit from us to make things easier,
|
|
|
or source CNC and 3D printed material yourself. We will be offering it
|
|
|
in the preassembled and kit form.
|
|
|
|
|
|
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 are mostly interested in the freedom of the Bitcoin Standard,
|
|
|
helping the Bitcoin network to remain decentralized, and want a device
|
|
|
that just works without a NERD-like technical knowledge in hardware
|
|
|
design and software engineering, the KAFI edition is the one for you.
|
|
|
|
|
|
We are taking all the knowledge and learnings from the NERD edition and
|
|
|
designing most of the parts ourselves here: from mechanical parts and
|
|
|
enclosure to PCBs for an optimal device solution where hardware and
|
|
|
software function well together. All of the work is open
|
|
|
source.
|
|
|
|
|
|
The KAFI edition is still work-in-progress and will be available soon.
