Simple scripts to create a Komodo Smart Chain using a single node for testing

This repository automates the steps described in the doc: https://developers.komodoplatform.com/basic-docs/smart-chains/smart-chain-tutorials/creating-a-smart-chain-on-a-single-node.html

Assumes Ubuntu desktop environment, may need tweaks for others

Step 1

Create a file named data and add the following contents:

name=<SMARTCHAIN-NAME>
srcdir=/home/<USER>/komodo/src
launch="komodod -ac_name=$name -ac_supply=10"
datadir=/home/<USER>/coinData

• name is the Smart Chain's desired name
• srcdir is the absolute location of the directory which contains komodod and komodo-cli
• launch is the custom launch parameters of the Smart Chain, don't include -pubkey or -addnode
• datadir is the absolute location of the directory to which the data directories of the second daemons are saved, no need to create it, the script will do it for you

Step 2

Create a file named keys and add the following contents:

pubkey1=02xxxxxxxxxxxxxxxxxx
pubkey2=03xxxxxxxxxxxxxxxxxx
privkey1=Uxxxxxxxxxxxxxxxxxx
privkey2=Uxxxxxxxxxxxxxxxxxx

• pubkey1 and privkey1 are a pair of keys used to launch the first daemon
• pubkey2 and privkey2 are a pair of keys used to launch the second daemon

Step 3

Execute the create-assetchain.sh script, it will launch two terminals each with a daemon running. It also imports the privkey corresponding to the pubkey for the respective daemons. Use the scripts c1 and c2 to interact with the 1st and 2nd daemons respectively.

Example:

./c1 getinfo # Get info of the first daemon
./c2 setgenerate true 1 # Start mining with the second daemon
./c2 getbalance # Get balance of the second daemon

Use the stop method to gracefully stop the daemons.

The script can be used to both create new Smart Chains or to launch an existing one.

Note: Executing create-assetchain.sh explorer installs the explorer too

Start

Once the initial launch is done and the daemons have been shut down, the start.sh script can be used to launch the daemons and start mining on the first daemon

Stop

To stop both the daemons, use the stop.sh script

Reindex

For the first time any of the indexes: address,transaction,spent are added to the conf file, a reindex is needed. Use the reindex.sh script to do that. It also opens the debug.log corresponding to the daemon being reindexed in a new terminal.

Example:

./reindex.sh # reindexes both daemons
./reindex.sh 1 # reindexes the first daemon
./reindex.sh 2 # reindexes the second daemon

Explorer

Use install-explorer.sh to install the explorer for your assetchain. You can use the command ./start.sh explorer to start the explorer along with the coin daemons after it has been installed.

Cleanup

To remove the Smart Chain completely, execute the cleanup.sh script. It removes the data directories of both the daemons, the explorer script and explorer installation. This is typically done to start another Smart Chain with the same name. To target the removal of a Smart Chain other than the one described in the data file, use ./cleanup.sh SMARTCHAIN-NAME

Collect backtrace

Use the ./gdb-start.sh script to start both the daemons using gdb
