Devchain configuration

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

From within ~/ckb_dev:

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

2. Download the corresponding chain spec file based on mainnet.

3. Initialize dev chain and import mainnet chain spec:

ckb init -c dev --import-spec /path/to/downloaded/mainnet.toml --force

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

name = "ckb_dev"

5. 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

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

[pow]
func = "Dummy"

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.toml file under the [logger] section set:

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

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

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

10. Activate the new spec for the first use by running the following command for a few seconds:

ckb run --skip-spec-check --overwrite-spec

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

(trap 'kill -INT 0' SIGINT; cd ~/ckb_dev/; ./ckb run --indexer & sleep 1 && ./ckb miner)
