LACChain EOSIO Node Installation

Testnet Chain ID: 5821525c6588037e2b066b992fcac34909a5b7f1ea8d5a393f6720fca3750d61

Testnet Genesis File: genesis.json

1. Install EOSIO from precompiled binaries

EOSIO version tag: v2.0.12

Download the latest version of EOSIO for your OS from: https://github.com/EOSIO/eos/releases/tag/v2.0.12

For example, for ubuntu 18.04 you need to download eosio_2.0.12-1-ubuntu-18.04_amd64.deb

You can use apt to install it:

apt install ./eosio_2.0.12-1-ubuntu-18.04_amd64.deb

It will download all dependencies and install EOSIO to /usr/opt/eosio/v2.0.12

2. Configure LACChain EOSIO Node

mkdir ~/eosio-testnet
cd ~/eosio-testnet
git clone https://github.com/lacchain/eosio-network ./

• Edit config.ini depending on your node type based on the sample config files provided

  • Enter your server's external address: p2p-server-address = YOUR_DOMAIN_OR_IP:9876

• Open TCP Ports 80/443, 9876) on your firewall/router

Sample config.ini files

• Validator Node: validator-config.ini
• Boot Node: boot-config.ini
• Writer Node: writer-config.ini
• Observer Node: observer-config.ini

Writer middleware for RPC API

The LACchain governance model requires that every transaction include two signatures, the user that originates the transaction and the writer node that allocates the required network resources to execute the transaction. The entity operating the writer node is responsible for the transaction.

This requirement is met by running the following HTTP service as a proxy to the writer node RPC API endpoint. Writer node RPC API middleware

3. Start your node

Specify a genesis.json file the first time you run nodeos

./start.sh --delete-all-blocks --genesis-json genesis.json

Follow logs to check your node is running OK.

tail -f stderr.txt

Check if you can access your node using link http://**YOUR_SERVER**/v1/chain/get_info

Here is an API Example

Starting and Stopping Nodeos

• ./start.sh Starts and restarts Nodeos service.

• ./stop.sh Performs graceful shutdown of Nodeos service.
