An instant, zero-config bostrom blockchain.


What is localbostrom?

Localbostrom is a complete bostrom testnet containerized with Docker and orchestrated with a simple docker-compose file. It simplifies the way smart-contract developers test their contracts in a sandbox before they deploy them on a testnet or mainnet.

Localbostrom comes preconfigured with opinionated, sensible defaults for standard testing environments.

localbostrom has the following advantages over a public testnet:

  • Quick to reset for rapid iterations
  • Simple simulations of different scenarios
  • Controllable validator behavior

Prerequisites

Install localbostrom

  1. Run the following commands::
$ git clone https://github.com/cybercongress/localbostrom
$ cd localbostrom
  1. Make sure your Docker daemon is running in the background and docker-compose is installed.

Start, stop, and reset localbostrom

  • Start localbostrom:
$ docker-compose up

Your environment now contains:

Stop localbostrom:

$ docker-compose stop

Reset the state:

$ docker-compose rm

cyber

  1. Ensure the same version of cyber and localbostrom are installed.

  2. Use cyber to talk to your localbostrom cyber node:

$ cyber status

This command automatically works because cyber connects to localhost:26657 by default

The following command is the explicit form:

$ cyber status --node=tcp://localhost:26657
  1. Run any of the cyber commands against your localbostrom network, as shown in the following example:
$ cyber query account bostrom1phaxpevm5wecex2jyaqty2a4v02qj7qm5n94ug
  1. If you want to hard restart the network (drop state and start from the genesis) you can use hard_restart.sh script
chmod +x ./hard_restart.sh
./hard_restart.sh

Cyber SDK for Python

Connect to the chain through localbostrom's LCD server:

from cyber_sdk.client.lcd import LCDClient
cyber = LCDClient("localbostrom", "http://localhost:1317")

Configure localbostrom

The majority of localbostrom is implemented through a docker-compose.yml file, making it easily customizable. You can use localbostrom as a starting template point for setting up your own local Terra testnet with Docker containers.

Out of the box, localbostrom comes preconfigured with opinionated settings such as:

  • ports defined for RPC (26657), LCD (1317) and FCD (3060)
  • standard accounts

Modifying node configuration

You can modify the node configuration of your validator in the config/config.toml and config/app.toml files.

Pro tip: Speed Up Block Time

localbostrom is often used alongside a script written with the Terra.js SDK or Terra Python SDK as a convenient way to do integration tests. You can greatly improve the experience by speeding up the block time.

To increase block time, edit the [consensus] parameters in the config/config.toml file, and specify your own values.

Modifying genesis

You can change the genesis.json file by altering config/genesis.json. To load your changes, restart your localbostrom.

Accounts

localbostrom is pre-configured with one validator and 10 accounts with boot balances.
