Tweakin the Pi…OKCash

It’s strange how a minor irritation can transform into a major bugbear – and so it goes.
Rokos version 8 on my raspberry pi(2 model B 1Gb) does not keep time and I find myself manually adjusting the settings…irritating…..sometimes I wonder if I am ever so slightly autistic.

From settings select Time and Date

Unlock and select Keep synchronized with Internet servers which will result in a request to install NTP


and then select the time zone

and lock

on reboot the Pi will magically reproduce the correct time.


select Settings and go to Options, tick ‘detach databases at shutdown’ and Apply

select Settings and go to change passphrase

Unless you have an exceptional memory that can remember a random 10 character password or a random selection of seed words then a good option in which to store your passphrase and other passwords is Keepass. I know it doesn’t get crazier than this…..a master password to unlock all your other passwords!

(It works for me 🙂

In order to install KeePassX first of all update the Pi

Type sudo apt-get update in Terminal and press Enter

and install keepassx

Type sudo apt-get install keepassx in Terminal and press Enter.

From the main menu Keepass will be installed under accessories



Moving OKcash wallet from Windows to a Raspberry Pi

First things first: build OKcash on the Raspberry Pi using the Rokos installation

Download latest rokos version – in this case version 8 – download the checksum text file to verify the download. Check the hash using an online hash calculator such as the site listed below

Compare the results with results contained in the text file

Extract the image file. The .rar file expands from 2.3Gb to a 5.9Gb .img file

If you have problems extracting the rar file with Xarchiver and get this cryptic error :-

An error occurred! Please check the ‘Store Archiver Output’ option to see it.

Try installing unrar

# apt-get install unrar

and extract the file using the following command

# unrar e <filename>

Burn image file to the SDcard. For Linux users there is an excellent product from called Etcher which can be downloaded from

It also has versions for Windows and MacOs

The only part of the SDcard useable at the moment is the size of the image file, the rest of the SDcard will have several Gb of unallocated space depending on the size of your SDcard. Resize the active partition to take full advantage of the whole SDcard space. For Linux users Gparted is the easiest utility.

Next insert the SD card into your Raspberry Pi device and switch on the power. (password is ‘rokos’)At this stage it is prudent (though not essential) to update your system and change the password, this can be done on the Raspberry Pi by using ‘Software updater’ from the system menu option. If you are unsure how to change your password here is a useful guide:-

Quite often software updater will fail with the following error message

Software Updater does not have enough disk space on the /boot drive. 

If this occurs the easiest solution, (although not the quickest) is to use Gparted ‘move’ the ext partition and ‘resize’ the boot partition

After successfully booting the Raspberry Pi navigate to the following directory


The following script will bootstrap the latest OKcash blockchain to your SDcard and create an empty wallet


USB stick

There are good reasons to keep the blockchain and wallet on a USB stick. If you only have a 8Gb SDcard there is not much room for the blockchain to grow. Even if you have a larger SDcard to future proof your node and keep the system on ‘auto-pilot’ it is better to keep system and application files separate from data files. Additionally the separation makes housekeeping procedures easier to implement.

Automount will place your USB stick in the location below


The following configuration statement needs to be added to okcash.conf (use Mouspad or something similar)


And the files from the “/home/pi/.okcash” directory need to be copied to your USB stick

so that when OKcash is launched it will use your USB as the default directory for the wallet and blockchain.

Syncing the blockchain

The bootstrap will contain 90%+ of the total blockchain, at this stage the OKcash wallet still needs to sync up to the network. This will probably take about 3 to 4 hours.

Once the blockchain is in sync your Windows OKcash wallet can be copied onto your USB stick.

“wallet.dat” can be found in the following directory on Windows systems:-


by default this looks something like C:\Users\username\AppData\Roaming\OKCash

Note that “AppData” is an hidden folder

Before relying exclusively on your Raspberry Pi installation take your time to test a few transactions, ‘soak’ test the installation for at least a few days and make a backup of your USB stick.

Note your Raspberry Pi will locate your USB stick on reboot but will NOT mount the USB until you manually access it. Failure to mount the USB stick before loading OKCash can result in a corrupt blockchain.

Note also that on my Raspberry Pi Firefox would not load; if this is the case the Midori browser can be installed using the following in Terminal

sudo apt-get install midori

FOMO : Monero XMR

After a brief dip Monero is on the rise again, according to Cryptocurrency Market ( $142.92 on Monday 28-08-2017 (04.03 GMT). Most observers agree the listing of Monero on the South Korean exchange bithumb will have a positive effect on the Monero price. Newcomers entering this market should note that Monero may have peaked too soon with the possibility of a price fall. My own personal belief is that given the incentives provided by bithumb  Monero’s price is likely jump significantly over the next week or so with the inevitable correction shortly afterwards.


For people buying into the Monero market now this presents a FOMO moment.

bithumb deposit address is now open and the listing day is August 30th, 2017 Midnight – although some details may have been lost in translation as the website infers that the 30th is Sunday?!

It is sobering to reflect on the fact that for the first 3 months of 2017 the price of Monero hovered around $12. FOMO strikes again

Fear Of Missing Out

FOMO : Bitcoin Cash

If like me you sold at 500$ or less FOMO is beginning to take hold. At 300$ you thought ‘OK’ long term Bitcoin Cash has nowhere to go so it’s time to sell, after all it’s free money….but now the doubts are setting in. (740$ !!)

Maybe short term to medium term there will be a concerted effort to usurp Bitcoin’s position as the top cryptocurrency with the likes of Goldman Sachs who have been very vocal recently about Bitcoin as a rising asset class. My conspiracy head has just revealed that this is a double bluff and that the establishment finance will be investing heavily in Bitcoin Cash for a ‘pump n dump’. Don’t say you haven’t been warned.

If you still own Bitcoin Cash sell half now and the rest when it gets to 2000$

Arrrrrrrrrrrrrrrrrrrrrgh FOMO !!

Fools Gold, Minergate, Darkcoin and why Only fools and horses work.

Its Friday just after 12 noon and I’m working local, which means I can nip home for dinner. An hour or so of idleness, email, Twitter, Facebook the usual – and then check out Bitcoin – a nice gentle rise in price and a welcome relief from the recent steady state. Finally I check out Minergate, I had been meaning to compile a list of ‘up & coming’ Alt coins but had never really gotten round to it – installing Minergate (on Windows especially) is an easy option and mines a number of coins I have an interest in, such as Monero and ByteCoin.

Another coin that has taken my interest is Darkcoin although the last time I’d looked at Darkcoin was probably more than 12 months ago. Other coins of interest are those which are unlikely to give way to ASIC mining. That is coins that can only be CPU / GPU mined. Even GPU mining seems to be an ever increasing arms race that requires an upgrade of specialised rigs every 6 months or so.

I have been running Minergate (CPU mining only – no GPU) in the background on a Windows 7 desktop for a number of days; whilst surfing or using general office software, Minergate has no noticeable effect on software responsiveness but I can hear that the processor is working hard judging by the increased noise of the fan. So it must be drawing down much more power than usual.

I know that this is not profitable and that I am probably just wasting electricity but in most cases I’m using the computer anyway, although sometimes I have left the computer running with the monitor switched off and the power option in Control panel set to continuous. As I live with a teenager and a 27 year old who acts like a teenager conserving electricity in my household is not a high priority and I can’t be wasting anymore electricity than my 2 teenagers ( lights,television left on – towels stuffed into the dryer straight from the washing machine…….its a long list)

Some interesting stuff about Darkcoin – Darkcoin started life as Xcoin and has recently changed its name to Dash. This most recent name change March 25, 2015 was to disassociate itself from the ‘Dark’ web and create a brand as far away as possible from the likes of the now defunct Silk road and the recent rise of Silk road copies. Unlike Bitcoin and other earlier cryptocurrencies Darkcoin Dash uses a chained hashing algorithm of eleven rounds known as X11 for proof-of-work.

‘This is so that the processing distribution is fair and coins will be distributed in much the same way Bitcoin’s were originally. ASICs will be much more difficult to make for these algorithms and should take years.

With chained hashing, high end CPUs give an average return similar to that of GPUs. An added benefit of the algorithm is that GPUs require approximately 30% less wattage and run 30-50% cooler than they do with Scrypt.’

To add privacy to transactions Darkcoin Dash uses a system known as Darksend which is basically a coin mixing system based on CoinJoin. Blah, blah, blah, blah. The details and technicalities of this coin are travelling way above my understanding – I check out the price – 1 Darkcoin Dash is equal to 2 dollars 38 cents, not bad for a ‘new’ coin.

Suddenly I realise my dinner hour has stretched to 90 minutes and I should have been back a work a while ago. I take a quick glance back at Minergate

AEON zilch nada

BCN 6529

DSH 1302

I glance down to Monero – XMR 0.028158189060

and then back to DSH

DSH – surely DSH is DASH – I have no time to check and flick the screen off leaving Minergate to mine DASH !!

All afternoon my mind keeps wandering back to the impossible possibility that DSH is DASH. The time now is 13:45 I have 1302 of DSH – that’s $2000 at least. By the time I finish work I’ll have about 10 grand.

‘This time next week – we’ll be millionaires !!’ -Only fools & horses

Deep down I knew DSH was not Dash but it was nice to dream for an afternoon. DSH is the short code for Dashcoin – currently trading against the dollar

1 DSH = 0.0011810252 USD

Technically Dash (short code DASH) is a great example of an Alt coin that fits a need; the equivalent privacy of fiat ‘cash’. Dash is truly Digital cash in which it is extremely hard trace a transaction trail. In this niche(?) market lies its success as reflected by it current price. The only downside at present is its confusion with its brand name. Xcoin to Darkcoin to simply DASH and not Dashcoin; additionally putting Dash into a search engine does bring up some interesting sites totally unrelated to DASH. Other than that I believe DASH is an Alt coin to watch, mine and buy.

Disclaimer – Dash is DASH and should not be confused with Daesh. This is only mentioned for the benefit of the NSA , GCHQ and the rest of the five eyes. Plus it might increase website hits.
