1  Bitcoin / Electrum / How to sign a transaction from paper (load transaction from text)? on: April 09, 2015, 03:28:16 PM
Hey,

Basically, I'm producing a piece of documentation for a university degree project aiding businesses adopting Bitcoin telling them literally everything they need to know. The wallet client I'm recommending is Electrum, because I just personally love its simplicity, light-weightedness and un-cluttered GUI. It's just great, and I personally use it myself. Anyway, I know how to sign transactions from a cold storage using a USB flash drive (I utilise this quite often myself for personal use), but how the hell do you do it with paper?

On the watching only wallet: Tools > Load transaction > From text, obviously. But what goes in that box? I'm just not sure what I need to write down from the unsigned transaction to put in that box you know...

I'd like to be able to include how to use this feature in my work, advising that it's a useful feature if you need to send funds from a PC that you know full-well is compromised and you don't want to expose your cold storage. Obviously, smart malware can infect a USB flash drive and collect information from your offline wallet to transmit to the malware-host later when the flash drive is running on a machine with internet. It's just nice piece of mind if a client were to have tens of grands worth of funds in the wallet, and a really awesome feature none-the-less if I could figure it out.

PS.
If you want to help what I'm doing here a little I'd really appreciate you check this out: https://bitcointalk.org/index.php?topic=1012211.0
If you fill out that Google form and give me complete written answers I'd be willing to pay 0.002 or more per response depending on the quality.

Thanks in advance!

EDIT: Oh, Electrum 2.0.4 btw

EDIT: Figured it out. For anyone interested:
Save your unsigned transaction, and edit the file with a text editor. Putting the hex code into that box on the watching-only wallet worked, that'd be an absolute ballache to have to write down however. If there's a shorter piece of code that can go in that "load transaction from text" box, more suitable for someone writing it down. Please do let me know.

Cheers!

Hi all,

First off I do have a main account on here and am fairly active (but don't want my account here associated with this one for privacy reasons). Not to mention I'm a huge cryptocoin geek.

My final year degree project is about cryptocurrency adoption in retail and e-commerce, and I've produced a kind-of survey for you guys so I can add some quotes from this community in the report section - directly quoting forums isn't really "professional", what we write has to be quoted from publications written by other people (unless we've "conducted research" which is what I'm doing here). Pretty limiting, what a facade, right? Tongue. Anyway...

If you own an e-shop that either exclusively accepts cryptocurrency, or even just accepts it as one of many methods of payment it'd be awesome if you could get in touch with me via PM to answer a more fitting (and much shorter) set of questions regardless of how big or small you are. The reason I'm basing my project on digital currencies is down to my huge interest in them, and to push towards more widespread adoption hopefully even with regards to actual brick and mortar stores. The technology is all here (albeit in it's early stages of development admittedly), the world just needs educating. I honestly believe this technology can change the world, I just hope we can push it out and it can gain more momentum than the debt-driven war paper we currently have to use.

Anyway I'd really appreciate any input I could get here, especially if you're writing detailed answers. You could probably rush through it in under 5 minutes, but if you're providing written, detailed answers it'd probably take 10-15m.

Here's the link: http://[Suspicious link removed]/forms/f8WNE4LQfW
EDIT: https://docs.google.com/forms/d/1aT0mSmsL6rwOs8sA34voNkQc-nxpPs1Ce4d6rXOc6V8/viewform?usp=send_form (not sure why the forum removed the short-link)

All my friends know about Bitcoin because of me, some (4 properly using it) are even saving and betting with it (because it really is easier once you know how). I've spoke to some local stores, 1 of which seems really interested in accepting it (unfortunately don't think I'll be able to set them up before my report deadline so I can document it for grades, but still...). So yeah, I'm not leeching from you guys for my grades, I believe in, and enjoy what I'm doing here. Smiley

Oh, if possible keep the deepweb connotations to a minimum if any of you onion-heads are reading Tongue. I'm sure you're all aware the media is using those connotations to scare people away from crypto, and I'm trying to help remove that stigma. I've even got reliable sources quoted proving that a higher percentage of USD is spent on contraband than that of Bitcoin (yep, not just because the USD is more widely used - size is factored in).

Anyway, any and all input is seriously appreciated.
Hope you can help me help crypto!  Cheesy

Peace
