Setup

Environment Setup

0. Install Git
1. Install Node.js 16 LTS
2. Create ckb_dev folder and move the compiled node ckb#4097 in it:

mkdir ~/ckb_dev &&
cd ~/ckb_dev &&
git clone https://github.com/nervosnetwork/ckb.git &&
mv ckb ckb_tmp &&
cd ckb_tmp &&
git fetch origin pull/4097/head &&
git checkout -b pullrequest FETCH_HEAD &&
make prod_portable &&
mv ./target/prod/ckb ~/ckb_dev &&
cd .. &&
rm -fr ckb_tmp

Devchain configuration

This is section takes material from both Nervos devchain guide and Ian instructions.

1. Copy the data directory from an existing ckb mainnet installation to ckb_dev:

cd ~/ckb_dev &&
cp -r ~/.config/Neuron/chains/mainnet/data .

2. Download the corresponding mainnet spec and force import it into a devnet spec:

cd ~/ckb_dev &&
wget https://raw.githubusercontent.com/nervosnetwork/ckb/develop/resource/specs/mainnet.toml &&
mv mainnet.toml mainnet_tmp.toml &&
./ckb init -c dev --import-spec mainnet_tmp.toml --force &&
rm mainnet_tmp.toml

3. In the specs/dev.toml file change the first line to:

name = "ckb_dev"

4. In the specs/dev.toml file under the [params] section set:

[params]
genesis_epoch_length = 1743 # keep genesis_epoch_length the same as original file
# Other parameters...
initial_primary_epoch_reward = 1_917_808_21917808
secondary_epoch_reward = 613_698_63013698
max_block_cycles = 10_000_000_000
cellbase_maturity = 0
primary_epoch_reward_halving_interval = 8760
epoch_duration_target = 2 # instead of 14400
permanent_difficulty_in_dummy = true

5. In the specs/dev.toml file under the [pow] section set:

[pow]
func = "Dummy"

6. In the ckb.toml file under the [logger] section set:

[logger]
filter = "ckb-script=debug"# instead of "info"
# Other parameters...

7. In the ckb.toml file under the [block_assembler] section set:

[block_assembler]
code_hash = "0x9bd7e06f3ecf4be0f2fcd2188b23f1b9fcc88e5d4b65a8637b17723bbda3cce8"
args = "0xc8328aabcd9b9e8e64fbc566c4385c3bdeb219d7" # ckt1...gwga account
hash_type = "type"
message = "0x"

8. In the ckb-miner.toml file under the [miner.client] section set:

[miner.client]
# Other parameters...
poll_interval = 100 # instead of 1000

9. In the ckb-miner.toml file under the [[miner.workers]] section set:

[[miner.workers]]
# Other parameters...
value = 200 # instead of 5000

10. In a new terminal start ckb node and miner:

(trap 'kill -INT 0' SIGINT; cd ~/ckb_dev/; ./ckb run --skip-spec-check --overwrite-spec --indexer & sleep 5 && ./ckb miner)
