public testnet
This document is internal notes for the Graphene developers on how to start up a new public testnet.
Starting genesis file:
8ff86468d7da87ae73a0a1fdc8adbf6353c427aacba7e27d33772afddabb5b07 genesis/aug-17-test-genesis-c.json
Run following commands:
cp genesis/aug-17-test-genesis-c.json genesis/gnew1.json
sed -i -e 's/"block_interval": 1/"block_interval": 5/' genesis/gnew1.json
sed -i -e 's/"\(block_signing_key\|owner\|owner_key\|active_key\)": "BTS/"\1": "GPH/' genesis/gnew1.json
PREFIX=aaaa
programs/genesis_util/genesis_update -g genesis/gnew1.json -o genesis/gnew2.json --dev-account-count=1000 --dev-balance-count=200 --dev-key-prefix "$PREFIX"
Create data dir: programs/witness_node/witness_node --genesis-timestamp 10 --genesis-json genesis/gnew2.json --enable-stale-production --data-dir data/gnew
Display witness keys and ID's for copy-pasting: programs/genesis_util/get_dev_key "$PREFIX" wit-block-signing-0:101 | python3 -c 'import json; import sys; print("\n".join("""private-key = ["{public_key}", "{private_key}"]""".format(**d) for d in json.load(sys.stdin)))' | sh -c 'cat >> data/gnew/config.ini' python3 -c 'print("\n".join("witness-id = "1.6.{}"".format(i) for i in range(1, 102)))' | sh -c 'cat >> data/gnew/config.ini'
Also set p2p and rpc endpoints.
NB you have to go into config.ini and move them around to the main section, it does not play nicely with appending because of sections.
We need to blow away the previous blockchain so we can rewrite the genesis timestamp:
rm -Rf data/gnew/blockchain
Open up a new file in a text editor to take some notes. Run the witness node like this:
programs/witness_node/witness_node --genesis-timestamp 10 --genesis-json genesis/gnew2.json --enable-stale-production --data-dir data/gnew
You should copy-paste a line like this into your notes:
Used genesis timestamp: 2015-08-31T18:36:45 (PLEASE RECORD THIS)
You should also copy-paste the printed chain ID since you will need it in the next step.
The genesis timestamp needs to be pasted into genesis.json
file in the
initial_timestamp
field. If you do not do this, nodes using the
genesis will have a different chain ID and be unable to connect.
(Essentially the --genesis-timestamp
option in the previous step tells the node
to overwrite the time in the file with a timestamp after startup.)
