litecoin - Bitcoin Stack Exchange


To all DECENTants,
I would like to encourage you to become a seeder or witness (actually not miner) on DECENT.


As a pioneer with Bitcoin I truly believed in the DCT project and it's proposal. The first day of the ICO release I sent all my BTC balance to the DECENT. Not knowing when and what they will deliver. To participate in this great adventure means a lot to me. Another project from my home country I strongly encourage you to get familiar with is Ethereum. I have been an early CPU miner: before Crypto Currency I used to compute for sience projects grid for Clean Water and Cancer Research. If I hadn't bought Rainforest with the Ripple they distributed to all contributors, I'd be a rich man today. :P






GRAPHENE CLI Wallet Cookbook



A dedicated server with Linux Ubuntu 16.04 LTS is most recommend for 24/7 operation. I suggest you close the root and create a new user with SSH Key, secure the system with a firewall.

1. Create a new user

adduser bob 

2. Elevate him

usermod -aG sudo bob 

3. Generate a new keyset


4- Bind the new keys

ssh-copy-id [email protected]_server_ip 
Copy the keys to your local drive. You'll need them to connect.

5. Change the config file

sudo nano /etc/ssh/sshd_config 
Change Line PasswordAuthentication no

6. Finish with

sudo systemctl reload sshd 

7. Login with your ssh key, user and password

ssh [email protected]_server_ip 


1. Grab your tools

sudo apt-get update sudo apt-get install build-essential autotools-dev automake autoconf libtool make cmake checkinstall realpath gcc g++ flex bison doxygen gettext git qt5-default libqt5svg5-dev libreadline-dev libcrypto++-dev libgmp-dev libdb-dev libdb++-dev libssl-dev libncurses5-dev libboost-all-dev libcurl4-openssl-dev python-dev libicu-dev libbz2-dev 

2. Download and build Boost 1.60.0

mkdir -p ~/dev/DECENTfoundation/DECENT-Network-third-party cd ~/dev/DECENTfoundation/DECENT-Network-third-party rm -rf boost_1_60_0* boost-1.60.0* wget tar xvf boost_1_60_0.tar.gz mkdir boost-1.60.0_prefix cd boost_1_60_0 export BOOST_ROOT=$(realpath ../boost-1.60.0_prefix) ./ --prefix=$BOOST_ROOT ./b2 install cd .. rm -rf boost_1_60_0 boost_1_60_0.tar.gz 


1. Clone the repo

mkdir -p ~/dev/DECENTfoundation cd ~/dev/DECENTfoundation #via ssh $ git clone [email protected]:DECENTfoundation/DECENT-Network.git #via url $ git clone cd DECENT-Network git submodule update --init --recursive 

2. Build and install Decent

mkdir -p ~/dev/DECENTfoundation/DECENT-Network-build cd ~/dev/DECENTfoundation/DECENT-Network-build cmake -G "Unix Makefiles" -D CMAKE_BUILD_TYPE=Debug ~/dev/DECENTfoundation/DECENT-Network cmake --build . --target all -- -j -l 3.0 cmake --build . --target install 


You don't want your server to shut down the process when you lose connection or quit.
I use tmux. Though nohup is sufficient for infrequent access. Use it when you fire up decentd after miner setup.
nohup ./decentd & disown 

1. RUN decentd - On first run decentd will create .decent in the home directory.

Always close it via Ctrl+C to save the current state Ctrl+S Freeze Ctrl+Q Resume

2. Get HELP

cd ~/dev/DECENTfoundation/DECENT-Network-build/artifacts/prefix/bin/ ./decentd -h 

3. RUN cli_wallet

Close it with Ctrl+D

4. USE cli_wallet

set_password xy unlock xy 

5. IMPORT your account

import_key decentgo_username your_private_key 

6. CREATE 3 sets of keys for your new account

write them down, don't use the ones below. ;)

1. new owner key


2. new active key

{ "brain_priv_key2": "FUSION BLART JAIL FESTAL LAXNESS ROSTEL TITI VANADYL PUG BATATA KAIK ROSETY STUCCO TETE BEMUDDY WUDGE", "wif_priv_key2": "5HvsjRsokHSeeUdRkM88JgLzYJ6vnc2e35CzyZNRnmh1fvm91Jz", "pub_key2": "DCT7G7KeUnMPVKXN2y8M7BnyosLRE3LtSnNp7kbxtYd9xHiBoX6wd" } 

3. new public signing key


7. CREATE your new account

register_account new_username pub_key1 pub_key2 decentgo_username true 

8. SEND some DCT to your new account

transfer decentgo_username target_username 3.00 DCT "memo" true 

9. IMPORT the new account

import_key new_username wif_priv_key2 

10. Close the Wallet and edit the config.ini inside /root/.decent/data/decentd/

private-key = ["pub_key2","wif_priv_key2"] 

11. Launch again and create your miner

create_miner username "proposal URL" true 

12. Change your signing key to 3rd keypair from suggest_brain_key

update_miner username "proposal URL" public_key3 true 

13. Edit the config.ini again inside /root/.decent/data/decentd/

enable-stale-production = true miner-id = "1.4.X" private-key = ["pub_key3","wif_priv_key3"] 

Your Server is now ready to run a DECENT witness.

Be aware that you should not close your daemon at any time.


get_brain_key_info dump_private_keys get_private_key public-key get_account texxi get_miner texxi list_my_accounts list_account_balances texxi set_desired_miner_count username 99 

Now get some support for your miner and join the community!

You can vote for me and I will gladly return the favor. Please make sure your server runs stable and you're not missing any blocks. Good Luck!

vote_for_miner username texxi true true

All voters will receive early preview access to my first cryptocurrency trading tool to be released in 2018. But remember: Always trade for good and invest in green.

Compile the Ultracoin Wallet on Linux

Since documentation and how to guides on ultracoin are almost non existent. I thought I could make one to share with you guys. I wanted to set up a Linux wallet (ultimately to make a node), since there are no guides on this specifically, I was lost. After some through googling, I finally got this ultracoind up and running. Here's a guide for ubuntu.
*Update ubuntu
sudo apt-get update
*install git to download the source code
sudo apt-get install git
*install the other necessary components
sudo apt-get install build-essential libboost1.48-all-dev libcurl4-openssl-dev libdb5.1-dev libdb5.1++-dev
*navigate to the home directory
cd ~ *download the ultracoin source code
git clone git://
*navigate to the downloaded files
cd ~ *navigate to the src file in the source code
cd ultracoin/src
*build ultracoind !This will take a while!
make -f makefile.unix USE_UPNP=-
*go back to the home directory
cd /root
*make the directory for the .conf file
mkdir .Ultracoin
*navigate to the new directory
cd .Ultracoin
*make and edit the .conf file
nano Ultracoin.conf
*paste this info in the .conf file
rpcuser="USERNAME" CHANGE THIS TO SOMETHING ELSE rpcpassword="PASSWORD" CHANGE THIS TO SOMETHING ELSE rpcport=44101 port=44100 daemon=1 addnode= addnode= addnode= addnode= addnode= addnode= addnode= addnode=
*Exit out of nano press control X, press y, then press enter
*go back to the src directory
cd /root/ultracoin/src
*start the dameon
./Ultracoind -daemon
That's it!
To find out how to use the daemon, go here
If you run into this error when compiling it -
If this - g++: internal compiler error: Killed (program cc1plus) Please submit a full bug report, with preprocessed source if appropriate. See for instructions. make: *** [obj/main.o] Error 4
it is most likely caused by a lack of ram to libboost
to fix it do this -
cd sudo dd if=/dev/zero of=/swapfile bs=64M count=16 sudo mkswap /swapfile sudo swapon /swapfile
I set this node up on a $5 vps from I cannot guarantee the uptime of any of the nodes listed. I obtained them from my -qt client. Feel free to comment and message me more permanent nodes as I couldn't find any listed for ultracoin.
I am no linux expert, but I believe this information to be correct. If I made any mistakes, please correct me.
