There should have been block halving but i'm not sure if yet.
Anyone comment on this?

Blocks have been halved again? 13.12500000?

Cheers!

Hi everyone!

I recently started mining via sgminer (gpu) on a stratum pool. My gpu is a SAPPHIRE HD 6770 1GB GDDR5 and now i can mine around 750 kh/s.
My question: Is this hashrate normal for this gpu? Can i increase my hashrate by adding a more powerful psu?

Thank you for your time!

Thank you!! it works fine!!

While Debian is the distribution upon which Ubuntu was based there are some important differences involved when trying to build Qt files.

If you want to build on Ubuntu use the instructions found here.

The following was originally written as a text file and has been only slightly edited for use here.

####################################################
#
# This file contains the sequence for building CannabisCoin wallets on
# debian systems. Builds were successfully completed on Debian version 7.8.
#
# Comments are particularly verbose in an effort to ease newcomers into building
# their own secure wallets on linux systems.
#
# While this file could easily be converted into a shell script please do not do so.
# Some commands must be run as root, most should not. Compile times will cause
# sudo permission sessions to expire, or at least they should and the script will fail.
#
# Commands are written here to be copied and pasted into a terminal session.
# Lines beginning with "#", like this one, are comments to help you understand
# the commands you are about to execute.
#
# Sometimes more than one command is included per line, joined with "&&", this
# is simply to reduce the number of times users need to copy and paste commands.
#
# Corrections, suggestions and comments are welcome and should be e-mailed to
# [email protected] or you can PM me here on bct.
#
# Good luck and may the source be with you
#
#####################################################
#
# Open a terminal - open the Applications menu at top-left of the desktop
# => Accessories => Terminal or alt-F2 to open the run dialogue and type terminal.
#
# Copy and paste the next line of text into the terminal window and press return.
# You will be asked for your password because you are installing system software.
# Keep doing the same thing with the next line beginning without "#" when your
# prompt returns, which will happen when the previous command has finished execution.
#
# *** Note that you may not be permitted sudo use yet, so let's change
# that now - you'll need the root password to do this.
#
# Tip: you can paste into the terminal either via the keyboard with shift-ctrl-v
# or with right-click => paste.



# Yes, just the two-letter command, then your root password when asked.
# Now add yourself to the sudoers group by replacing [your user name here] below
# with your username and running "usermod -a -G sudo I_love_CANN" or whatever
# your username may be.



# Now you need to give yourself the ultimate power by opening a special editor
# and adding a single line of text.



# It's not anything flash, no graphical WYSIWYG interface but it will check
# that you don't make any mistakes that will lock you out of your system
# With the down arrow move the cursor below the line that reads
# root  ALL=(ALL)  ALL
# and type



# it must be on a line all on its own, just like the root line above it.
# Then type control-o for write-out (which is just save), enter (or return), control-x.
#
# Provided visudo doesn't complain you should now be part of the elite
# superuser group. While you have your super powers we'll add another software source
# so that we can download the correct version of Berkeley database ( DB4.8 )
#
# The following command (series of commands, actually) will edit the list of software
# repositories searched by the system and will do so in neat, human readable form.
# Firstly it will add a blank line and then the comment reminding ourselves later
# just what we've done "# Add old stable and wheezy backports for DB 4.8 etc."
# followed by 2 older repositories.
#
# NOTE: look at the last two "echo" commands - see where it says
# "echo 'deb http://ftp.au.debian.org/debian/ oldstable main'" and so on?
# I use .au because I'm an Australian located in Queensland and that's closest.
# You could change ftp.au.blabla to your own country code for better service.
# Debian's mirror list is here: https://www.debian.org/mirror/list
# Copy the command into your text editor (type gedit and press return to open it)
# paste in the sample command, edit in your country code, ctrl-a then ctrl-c to
# select and copy it again, close without saving and paste your modified command into
# the terminal and execute by pressing return.



# Make the system aware of the changes



# Congratulations, you have just used your super powers to edit a system file
# That's enough for the moment though, so relinquish your super powers by typing exit



# Now, everyone ready? Fine, let's begin. This is where we start adding software
# so we can build our lovely fresh and known clean CannabisCoin Qt wallet.

# Be tidy - make a home for our source code and move to that directory



# Download and install the other required packages.



# Download the wallet source code



# Move to the correct directory to compile our wallet



# Now we set our desired options and generate the makefile, which is the instruction
# set for the compiler.

# To use UPnP for port forwarding behind a NAT router (recommended, as more connections
# overall allow for a faster and more stable user experience) set USE_UPNP=1

# USE_UPNP=0 to compile support for port forwarding but have it turned off by default,
# users can turn on in wallet options.

# USE_UPNP=- to compile without UPnP support, not sure why you'd do that.

# Notification support for recent Ubuntu family desktops is provided with USE_DBUS=1.

# QR codes are enabled with USE_QRCODE=1, USE_QRCODE=0 to compile without QR code support.

# The following should be completely safe as is or you can change the following command
# to suit your desired options.



# Now that our makefile has been written for us we simply execute the make command to
# build our CannabisCoin wallet



# When your prompt returns you know it worked or it will tell you if not.
# We'll move the executable to a directory on the path so we can run it at will



# We should just make our new wallet welcome



# Optionally we can add even more nodes to those originally listed in the config file,
# although the wallet will connect perfectly well without them. These last 3 were not
# included in the original file:



# Also optional, the following command will place a shortcut link on the desktop. If
# you prefer you can simply open a terminal and type CannabisCoin-qt at the command
# prompt to run your CannabisCoin wallet at any time.



# Can't see Computer, home, trash etc. on the desktop? No problem, just change a
# setting or two - open the Applications menu => System Tools => Preferences =>
# Advanced Settings, that will open a separate dialogue, click Desktop and then
# turn on "Have file manager handle the desktop", which is needed to display items
# on the desktop.

# If you have started your wallet please stop it now - we are going to speed up the
# block chain sync by importing a bootstrap file.


#########################################
#
# I hate this section - users should not be downloading anything from a random like me!
#
# Please note that the same bootstrap.dat file is available from CannabisCoin's
# core developer, Esotericism, via bittorrent - if you are comfortable with
# torrents the address is
# https://kickass.to/cannabiscoin-bootstrap-dat-january-23rd-2015-t10179152.html
# Torrent link is to redundant bootstrap file - new version should be downloaded from below instructions
#
# That said, you are still following a link from a forum post, so...
#
########################################

# We will now download a bootstrap file. Its purpose is to dramatically speed up
# synchronization of the wallet block chain by providing a local source of blocks
# up to January 23, 2015. You don't have to do so but you'll be glad if you do.

# We will use our browser to download the bootstrap file from mega. The
# default browser is called IceWeasel on Debian (it's still just Firefox rebranded)

# The next command will open your web browser and go to the appropriate mega
# download page, click the download button when it is offered.
# The file will download to your Downloads folder by default. Once it finishes close
# the browser and your prompt will return to the terminal window.



# After it finishes downloading we'll move it to where we want it and unpack it with
# the next two commands.




# Now that we no longer need our downloaded zip file we can remove it.



# OK, all being well we can now sync CannabisCoin so either click your desktop shortcut
# or execute the following command in the terminal.
# Tip: if you do run from the terminal open another terminal window so you can proceed
# while the wallet is running - the prompt won't return to the 1st terminal instance
# until the initiated process finishes, that means until you close your CANN-qt wallet.



# Depending on the speed of your computer syncing the blockchain could take some time.

# Tests run on a virtual machine hosted on a 2009-vintage core2 duo permitted just
# one cpu took more than 3 hours to complete.

# ******* IMPORTANT NOTE FOR DEBIAN USERS ********
#
# There is a non-critical flaw in Debian builds of the Qt wallet - one a lot of people
# apparently never find but it could be annoying if you are not forewarned.
#
# Opening child windows from the wallet, e.g. "Show QR Code" does not add close
# window controls to the child instance. This may leave users wondering how to
# get rid of the window once they are finished with it.
#
# The simple answer is alt-F4, alternatively right-click the title bar on the child
# instance and select the close menu item.
#
# This seems to be an odd Debian quirk, one I haven't yet found elsewhere.
# Just another way Debian users are special, I guess

# If you wish to save drive space you may remove the entire src directory we made
# earlier, which will remove no-longer required source code.

# Optional



# After updating is complete we can ditch the now-redundant bootstrap file, which
# the wallet renamed .old when it was finished with it.

Attention Fudsters:

 you're right; FUD can be a good thing. i think even the devs would admit that it is better to have the weak spots exposed before moving forward. but now can everyone say overboard?

respect and equal rights come somehow to mind

it is all good ;-D

[edit] much rather see the comunity coming together to help advertise and otherwise comunicate what we have to the general public than being embedded in each other's throats ...

        ...  might that be next?

It has been explained many times, but again:

Hidden Premine CANN??



Block #1 CANN created 21,882,000 CANN 

21,882,000 CANN x 0.00001257 : 275 BTC  

Wonder when this thread will be locked again and wonder how many weeks/months till we hear nothing. I think the money makers have left the building.

let them.  it's their right to do so.  it keeps the devs in check. 

@Jamesonotc

have u nothing else better to do? uve been on cann from day 1 talking crap. if u dont like cann then F@uk off to another coin as nobody want to listen to a 12 year old crying about this and that. grow up!!

Did anyone ever recover a copy of the CANN v1 blockchain?

Nice one!! will have a look later.

Note: this ready-to-go USB flash drive image is for people who do not wish to compile their own CannabisCoin software from the git repository, for which I have posted tutorials for Ubuntu and Debian. Compiling your own wallet on Linux is definitely preferable to downloading one built by some random (that would be me, in case you missed it ).

What is this?

It is an image of an Ubuntu 12.04.5 LTS installation, complete with a ready-to-use CannabisCoin wallet, zipped and ready to download and copy to an 8Gb or larger USB flash drive with Mac/Linux dd or Windows HDD raw copy. Mac users may also wish to consult "How to Boot a Linux Live USB Drive on Your Mac"

Instructions for expanding the image partition to make use of additional space on larger flash drives can be found here.

Please note that this is an UNOFFICIAL CannabisCoin wallet build compiled by B4zz4. The blockchain data is synced to about midnight (GMT) Saturday, February 7th, 2015.

Download does NOT include wallet.dat (you can copy in your own if you wish or simply run the wallet to create a new one).

Why would you want one?

Simple, boot into a clean operating environment to store/transfer your CannabisCoin with much reduced risk of malware and/or key loggers pilfering your coins. Provided you do not browse the web or download anything but keep the CANN USB solely for transacting your CannabisCoin business you are at very little risk of theft.

ALWAYS keep multiple copies of your wallet.dat file in multiple secure locations - USBs are not forever and will fail eventually. When the inevitable occurs simply construct a new USB copy, add a copy of your wallet.dat and you are back in business.

Where to get it?

cann1204.dd.zip has been uploaded on mega - if there is enough demand I'll see what I can do about a torrent although my upload speed is appallingly slow (as the poor people trying to download bootstrap.dat at the moment will likely attest).

How do you use it?

To begin with you need a functional computer and a spare 8Gb or larger USB. Any files on the USB will be destroyed so don't use one containing anything you want to keep.

Once you have downloaded the 3.2Gb zip file you need to unzip it to any suitable location. You will need at least 8Gb of free space to do so.

I tried in a Windows 7 VM and even Windows can extract cann1204.dd so that shouldn't cause any problems.

Windows users will need to download HDD Raw Copy Tool if they don't already have it.

Check carefully that you select cann1204.dd as the source and your USB as the target. BE WARNED THAT THIS SOFTWARE WILL OVERWRITE YOUR HARDDRIVE IF THAT IS WHAT YOU TELL IT TO DO!

Linux users open a terminal and run "sudo fdisk -l" to list drives and identify your target USB, if you only have one HDD your USB will likely be /dev/sdb.

Then it is simply a matter of "sudo dd if=[path to cann1204.dd] of=[path to USB] bs=1M", it will look something like "sudo dd if=~/Downloads/cann1204.dd of=/dev/sdb bs=1M" without the quotes. If your distribution complains about bs=1M then use bs=1m.

Mac users have slightly more to do but not much.

Open a terminal and run "sudo diskutil list" to identify your USB (run it before and after inserting your USB if you have difficulty telling one from another).

Then run "diskutil unmountDisk /dev/diskN" (replace N with the disk number from the last command).

Now run "sudo dd if=[path to cann1204.dd] of=/dev/rdiskN bs=1m" (we are using /dev/rdiskN instead of /dev/diskN because it may be faster). Same deal as before, if your particular version does not like bs=1m use bs=1M.

If you get a "resource busy" error it likely means you forgot to unmount the USB, do so now using Disk Utility.app (Finder => Applications => Utilities => Disk Utility.app). DO NOT EJECT THE DRIVE - UNMOUNT IT.

Everyone

Once you have copied cann1204.dd to your USBs you can eject the USB, it is ready to use.

If you know how to use a bootable USB you can go ahead when ready.

If not then there's a simple tutorial on booting from a USB here.

People with different keyboard needs should not change their password until after you change your keyboard settings.

The supplied user name is cann with the default password of YesWeCann. You are going to need to change that for the sake of simple security. The system is set for automatic login and cann has administrative rights.

NOTE: If your keyboard will not type "YesWeCann" then copy it to the clipboard and paste it into the terminal with right click => paste or with ctrl-shift-v when the time comes.

YOU MUST SET YOUR LOCAL TIMEZONE BEFORE YOU START THE WALLET WHEN YOU BOOT FOR THE FIRST TIME - THE USB IMAGE WAS CREATED IN QUEENSLAND AND EXPECTS LOCAL TIME TO BE GMT+10 - THIS IS IMPORTANT FOR SYNCHRONISATION OF THE BLOCKCHAIN.

Click the following image to go to a brief tutorial on changing the time and date settings in Ubuntu:


I'm trying to do this pictorially for the benefit of those for whom their first language is other than English. They will need to change their language and keyboard settings.


Add the necessary keyboard files:



Add the necessary language support:



Once you have the right keyboard and language set it is time to change your password, so open a terminal by pressing ctrl-alt-t or by clicking on that big button at the top-left of the screen and type terminal (you'll be offered a terminal before you type the whole word).

In the terminal type "passwd" without the quotes (make sure you remember your password - you are the only one who can change or reset it):


You will need to enter "YesWeCann" without the quotes and then your chosen password twice. You won't be able to see the characters as you type them.


Don't worry if you make a mistake entering your new password, the worst that can happen is that your password will not change:


Just type "passwd" again and try again.

OK, you have set your local time, your keyboard is correct and system menus and messages are in the language you are comfortable with, you just want to copy in your wallet.dat file and you are good to go... but where?


Linux hides many settings and data directories by preceding their name with a period - to show them in the file manager press ctrl-h or go to "View" => "Show Hidden":


and all will be revealed:


Go ahead, open up .CannabisCoin and see that there is no wallet.dat there (there will be either when you put one there or start your wallet, whichever comes first - if the wallet finds no wallet.dat file it will create a new one for you).


Alright, you want to get on with it. You have a few choices in how you open your wallet, you can click on the CannabisCoin icon in the bar at the left:


Or start typing cannabiscoin in the Dashboard:


And a familiar splash screen will open:


This might persist for a while as it rescans the blockchain, just let it do so and then it will connect to the network and sync.


Hopefully the above has been sufficient to help you get started with your own fairly safe environment from which to make your CannabisCoin transactions.

Anyone having trouble can PM me here or email me at [email protected].

In the meantime good luck everyone, have fun and smile.

well a lot of people did...  at over .0001!  those same people are either pissed, getting impatient or/and fudding the shit out of their wits.

jamesonotc is from a scam coin , be very careful he has no job and trying to take cann from people   he just a troll scammer that no one care for his words .  End story

did you?  i hope you all did.  making a profit in trading isn't a bad thing.
