4  Bitcoin / Project Development / New Version of my Offline Paper Wallet Generator on: May 11, 2013, 01:49:33 PM
I've made some improvements to my offline paper wallet printer.

Heres a new demo.

And a peek into the innards.

I'm working toward creating a shippable product so I'd really appreciate any advice.

I'm currently using ~45 worth of parts so a rough guess at a retail price would be 80-90 depending on the manufacturing effort.

Speed is the major problem at the moment so I'm going to investigate different microcontrollers/processors.

Are there any other suggestions to make this a more compelling product?

According to https://en.bitcoin.it/wiki/BIP_0016 BIP-0016 is still in draft.

I thought this BIP was accepted along time ago.
Unfortunately I don't have the necessary permissions to edit the page (it was locked indefinitely)

Can someone with the necessary permissions unlock the page or update its status.

In This post

https://bitcointalk.org/index.php?topic=119530.msg1286692#msg1286692

Its mentioned that the output of block 0 can't be spent as this would allow Satoshi to fork the network.

Can someone clarify what this means.
I don't understand how being able to spend an output can lead to a fork.

Thanks,

Steve.
