Topic: [ANN] CIYAM Safe - offline tx's using QR codes for comms - page 3. (Read 6157 times)

Yup - still 8 BTC remaining (in the title of the OP) and only one other member working on it at the moment.

Is there still a spot open for the reward?

It's well received. Thank you!

Use vi for editing

Thank you - and have sent 2 BTC (txid: 966e4ecc3c40828e63cd012c98f947494fd6aa907e0a993bf9926538aed6cd94) - good to know that the system is working (and yes you could always use USB rather than webcams - just depends upon your level of paranoia).

Proof that jl2012's answer was correct is that the private key for the 1ELPYyJKLfeQHPu3FCSSKfFHjhCkEbapct that was generated "offline" is 5Jo14o6CAYQin8WgqR59s1CQ4Hh4VirsnBSEizfE7sFb5r75i8g (so don't ever send BTC to that address again).


Okay - if you want to keep the private and two public keys you originally created then check the instructions about "restoring" at the end of "usage.html" otherwise you can just start from scratch ... or ... you could always "scan" the signtx script and send it across via QR.

Damn, I found the problem.  The signtx script was corrupted.   Now how should I go around to fix this ?
 No text editor, no internet connection for apt-get commands....

Well, I'm giving up for the night before I break more stuff. The ./signtx script does not return anything now after I mistyped the password the first time. I've restarted everything to no avail. 

Finally I copied the rawtx to the offline computer by an USB drive

Here you can see the transaction record: http://blockchain.info/address/1ELPYyJKLfeQHPu3FCSSKfFHjhCkEbapct

For the reward please send to 1CiZPrEJdN4FJcqdLdgVLzT8tgCXxT5ion

Thanks!

It works after I reflash the USB key

However, the webcam on my netbook (the offline computer) is not working. How can I move the raw transaction back to the offline computer?

PS: Do I need to issue this command in the online PC or offline PC?


I'm guessing on the online PC though...

Okay. I'll try to poke around with it at the meantime.

Thanks for the info John - will also add that to the doco!

Am tired now and need to sleep - will continue this in another 8 hours or so.

Yep - It has finally went through moments ago: http://blockchain.info/address/17QgF3oJCLAvzGg2hxPX6rMhS5tKebWsiz
Whew.

I'm running the system on a 4GB drive so I think 4 and above is okay. The raw is approx 2.7GB.

Can see John's tx now (he's half-way there).

You coins just hit the blockchain!

I think that 16 GB is required (although maybe this could be changed).

I have sent coins many times when being more than 100 blocks "behind" so I don't think it could be that.

Thx.

What size is required for the USB drive?

There's more than enough preconfirmed coins in the system. I would wager a guess that bitcoin-qt needs to catch up with all blocks before sending out a tx to thwart potential double spends.

For the "online" computer - absolutely (that's what I am using) - for the "offline" one you need to use the LiveOS (which is Linux).
