CLAMs are awesome!
Proof of stake, rather than proof of work, allows for everyone who's chipped in to receive a piece of the pie.
Follow the steps below to set up your own cloud CLAM digger (i.e. the equivalent of a bitcoin miner) on Digital Ocean
If you'd like to run this in the cloud:
- Sign up for Digital Ocean using referral code 9ff7327d7d00. You'll get $10 in credit once you've spent $25.
- On your local machine, create an SSH key
- Create a Droplet:
- Select the latest version of Ubuntu for your distribution image (currently v16.x)
- Select the cheapest option available that has at least 1GB of memory (currently USD $10/month)
- Paste the SSH key created above into your Digital Ocean droplet
- Make a note of your droplet's IP address
- Connect to your droplet:
- On OS X or Linux, simply type
ssh root@<your droplet's IP address>
(e.g.ssh root@24.101.102.103
) in a terminal window - On Windows, use Putty
- On OS X or Linux, simply type
Update the dependencies:
apt-get --assume-yes update
apt-get --assume-yes upgrade
Install build requirements:
sudo apt-get --assume-yes install git build-essential libtool autotools-dev autoconf pkg-config libssl-dev libboost-all-dev
CLAM (and bitcoin, and other cryptocurrencies) rely on Berkeley DB 4.8. Install it:
sudo add-apt-repository ppa:bitcoin/bitcoin -y
sudo apt-get --assume-yes update
sudo apt-get --assume-yes install libdb4.8-dev libdb4.8++-dev
Digital Ocean may require a temporary swap file for the current session. This will be cleared when the droplet is rebooted
You can skip this step if you're not on Digital Ocean
sudo fallocate -l 2G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
Create a workspace folder to work out of:
cd ~
mkdir workspace
cd workspace
Clone the latest stable source code for the CLAM client:
git clone https://github.com/nochowderforyou/clams.git
Build the code:
cd clams
./autogen.sh
./configure
make
make install
Configure CLAM:
- Run
clamd
and take note of the password - Run
sudo nano /root/.clam/clam.conf
and paste the following into the file (replacing the password and the email, as appropriate):
rpcuser=clamrpc
rpcpassword=<the password you copied earlier>
alertnotify=echo %s | mail -s "Clam Alert" <your email address>
- Make clam.conf owner-readable-only:
chmod 600 /root/.clam/clam.conf
@dooglus created a bootstrap file that can be used to speed up the syncing process:
cd /root/.clam
wget https://s3.amazonaws.com/dooglus/bootstrap.dat
You're ready to go! Start the CLAM client in daemon mode by typing: clamd
I recommend running the client within a tmux session:
tmux
nohup clamd &
This way, if your SSH connection gets terminated, you can get back in with tmux attach
If you'd like to view the progress in another tmux pane:
- hit
ctrl+b
followed by%
(a percentage sign) - enter
tail /root/.clam/debug.log
Not sure if clamd
is still running? Type:
ps aux | grep clamd
You should see something like this:
root 6095 99.8 54.3 2091068 1111256 pts/3 SLl Nov24 1270:34 clamd
root 8605 0.0 0.1 11748 2172 pts/0 S+ 01:26 0:00 grep --color=auto clamd
You should see a line like the first one, with 'clamd' on the right end of the line.
Run clamd help
to see a list of command available for use.
clamd getinfo
show basic info on your wallet (including total spendable balance)clamd listaddressgroupings
- show all addresses with a balanceclamd sendtoaddress <recipient_address> <amount>
- send a certain amount of clam counts to a particular recipientclamd getaddressesbyaccount ''
- list all your receiving accounts
Comments, criticism, feedback? Please let me know
Hello abmohan, many thanks for laying this out so clearly. The only issue I had was having to restart the clamd process. The bootstrap process wouldn't synch for me until I stopped and restarted the client. Eg. clamd stop. From what I have seen in the forums, I'm not the first to run into this problem. You might want to mention it in the directions. Thanks again!
