Join Amber as a Validator

This document introduces how to join the amber as a validator node.
Before you start, you must have a trusted server running bitcoincashnode's client with RPC enabled. The executable smartbchd will connect to it for querying staking information.
1. build the binary
Running the step 0, 1, 2, 3 of this document.
Then clone the source code of smartBCH and build the executable of smartbchd.
cd ~/smart_bch
git clone -b v0.4.2 --depth 1 https://github.com/smartbch/smartbch
cd smartbch
go build -tags "params_amber cppbtree" github.com/smartbch/smartbch/cmd/smartbchd
After successfully executing the above commands, you'll get a ~/smart_bch/smartbch/smartbchd file for amber.
2. prepare the working directory
cp ~/smart_bch/smartbch/smartbchd ~/build/smartbchd
cd ~
rm -rf .smartbchd
~/build/smartbchd init mynode --chain-id 0x2711
wget https://github.com/smartbch/artifacts/releases/download/v0.0.5/dot.smartbchd.tgz
tar zxvf dot.smartbchd.tgz
cp -rf dot.smartbchd/* .smartbchd/
3. Prepare the validator keys
Running step 1 and step 2 of this doc to generate validator key and consensus pubkey.
Then, copy the priv_validator_key.json to work directory by running command below:
cp ./priv_validator_key.json ~/.smartbchd/config/
4. Modify App config
Open the ~/.smartbchd/config/app.toml file to modify the information of the bitcoincashnode's client with RPC enabled.
# BCH mainnet rpc url
mainnet-rpc-url = "http://ip-address:8332"
​
# BCH mainnet rpc username
mainnet-rpc-username = "<my user name>"
​
# BCH mainnet rpc password
mainnet-rpc-password = "<my password>"
5. start smartbchd
cd ~/build
~/build/smartbchd start --mainnet-genesis-height=602983
6. Build createValidator Tx
Using validator private key and consensus pubkey generated in step 3 to build command below:
./smartbchd staking \
--validator-key=<your validator private key> \
--staking-coin=1 \
--consensus-pubkey=<your consensus pub key> \
--introduction=<your validator introduction> \
--type=create \
--nonce=0 \
--gas-price=10000000000 \
--chain-id=0x2711	
This command generate createValidator tx raw data, send it in step 8 below.
7. Get some BCH to Send Tx
Get some BCH from some one has BCH in smartBCH already to your validator account. To check your account balance like this.
curl -X POST --data '{"jsonrpc":"2.0","method":"eth_getBalance","params":["<your validator account address>","latest"],"id":1}' -H "Content-Type: application/json" http://127.0.0.1:8545
8. Send Tx to smartBCH Amber
Please follow step 1, 2 of this doc.
9. Vote your consensus pubkey in Amber Xhedge Contract
Please go to https://amber.xhedge.cash/ to split your BCH to LeverNFT and HedgeNFT, and vote for your validator just created.
