# This script is an experiment to clone litecoin into a
|
||||
# brand new coin + blockchain.
|
||||
# The script will perform the following steps:
|
||||
# 1) create first a docker image with ubuntu ready to build and run the new coin daemon
|
||||
# 2) clone GenesisH0 and mine the genesis blocks of main, test and regtest networks in the container (this may take a lot of time)
|
||||
# 3) clone litecoin
|
||||
# 4) replace variables (keys, merkle tree hashes, timestamps..)
|
||||
# 5) build new coin
|
||||
# 6) run 4 docker nodes and connect to each other
|
||||
#
|
||||
# By default the script uses the regtest network, which can mine blocks
|
||||
# instantly. If you wish to switch to the main network, simply change the
|
||||
# CHAIN variable below
|
||||
|
||||
# change the following variables to match your new coin
|
||||
COIN_NAME="MyCoin"

||||
COIN_UNIT="MYC"

||||
# 42 million lite coins at total
|
||||
