For some reason, DigitalOcean droplets, and perhaps other cloud providers, have /dev/random
blocking problems. This probably is because they are running many small computers on a single Linux instance and the entropy pool dries up pretty quickly. If this doesn't make sense, install Haveged and don't worry about it.
If it does, libsodium
, which is the public-private key cryptography library we use, uses /dev/random
with no option to use /dev/urandom
. Haveged solves this problem.
sudo apt-get install haveged -y
systemctl start haveged
systemctl enable haveged
pip3 install lamden
nano ~/constitution.json
{
"masternodes": [<list of vks here>],
"masternode_min_quorum": <int>,
"delegates": [<list of vks here>],
"delegate_min_quorum": <int>
}
Ctrl+X, save the file.
lamden <masternode | delegate> -k <sk in hex format> -bn <list of ip addresses that are currently online>
You can install a script to install the entire software.
wget https://raw.githubusercontent.com/Lamden/lamden/dev/INSTALL.sh
Always practice good saftey and examine the bash file before executing it.
