Join the mainnet of smartBCH As a validator

This document introduces how to join the mainnet of smartBCH 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 steps of this document.

2. prepare the working directory

cp ~/smart_bch/smartbch/smartbchd ~/build/smartbchd
cd ~
rm -rf .smartbchd
~/build/smartbchd init mynode --chain-id 0x2710
wget https://github.com/smartbch/artifacts/releases/download/v0.0.3/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
./smartbchd start --mainnet-genesis-height=698502

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=1250000000 \
--chain-id=0x2710

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 mainnet

Please follow step 1, 2 of this doc.

9. Vote your consensus pubkey in BCH mainnet

Connect someone running an BCH mainnet minner to vote for you.
