Devchain configuration

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

From within ~/ckb:

1. Init devchain:

ckb init --chain dev

2. 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"

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

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

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

[params]
# Other parameters...
epoch_duration_target = 2 # instead of 14400
genesis_epoch_length = 2 # instead of 1000
permanent_difficulty_in_dummy = true

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

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

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

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