Chia (XCH) build local private chain (regtest / self testnet) for testing

ChiaBuildFlow.txt

// chia node need ssl keys when connection , it auto gen ssl keys at init , so no offical open node or endpoint
// need build node , testnet no node to sync , so ... build regtest by self : )

// ============== chia mainnet just need

git clone --depth=1 https://github.com/Chia-Network/chia-blockchain
cd chia-blockchain
sh install.sh
. ./activate
chia init
chia start farmer

// then use RPC to watch sync status
// ============== chia mainnet is very easy right ?

// ============== start create chia regtest node (testnet , please use this for test only)

// first , you may want move ~/.chia to outside , like use `ln -s`
// then add this to `~/.profile` to change default network path

export CHIA_ROOT="~/.chia/regtest"

// remember use `source ~/.profile` to use new profile or just re-login

git clone --depth=1 https://github.com/Chia-Network/chia-blockchain
cd chia-blockchain
sh install.sh
  // enable evn
. ./activate
  // if you want mine genesis block (height 1) , you must install timelord , it only support linux / macos(with dorcker)
sh install-timelord.sh
  // test timelord is work or not
./vdf_bench square_asm 400000

  // init config
chia init

// plz remember main walllet , it start `xch`
// copy paste main wallet to `https://www.chiaexplorer.com/tools/address-puzzlehash-converter`
// `Enter a receive address below to convert it to a puzzle hash` convert to puzzle hash
// like {wallet} xch1l95ygggqn23veg0dk0hp2u9m0x3xcqejfykgjzk3cugz9kucad9seg7mr3
// to {puzzle_hash} 0xf9684421009aa2cca1edb3ee1570bb79a26c0332492c890ad1c71022db98eb4b

// if no gen key at init , you can use command `chia keys generate`
// if you forget main walet , you can use `chia keys show`
// but `chia keys show` will not show wallet's {puzzle_hash} , so you need to the website to convert it

  // start fix config.yaml
vim ~/.chia/regtest/config/config.yaml

// remove all farmer.network_overrides.config & farmer.network_overrides.constants all contrant
//         // MIN_PLOT_SIZE // min = 25 & it is `K` (ref)
//         // GENESIS_CHALLENGE // what you want
//         // GENESIS_PRE_FARM_FARMER_PUZZLE_HASH // your {puzzle_hash} without 0x
//         // GENESIS_PRE_FARM_POOL_PUZZLE_HASH // your {puzzle_hash} without 0x

  // start chia node, if you want disable timelord , you can change `all` to `farmer`
  // please use this command to start chia node (-r restart , make sure all service restart)
chia start all -r

  // and use this command to stop , (-d deamon , make sure deamon is stop)
chia stop all -d

// use command like `top` you can watch `vdf_client` is burning CPU
// if height > 10 , you may change this config (not yet tested)
// fix `timelord.sanitizer_mode` from `false` to `true`
// it may mine block when mempool has transcations , but it not work at height = 0
// and if you need confirm block > N , it not good , and it will not auto mine to get coinbase money

// ============ RPC command to check status , all need use ssl key (please mind keys path)
