Public Tgrade testnets

If you find this Repo, this is for the Tgrade mainnet preparation.
We have already assigned external validators for the task and not accepting newcomers. Thank you

Tgrade - MainNet-1

You can see the live network via our block explorer.
When you are ready to build a node, follow the instructions below:

Hardware Requirements

For running a tgrade validator. We tested successfully with the following Architecture:

• Ubuntu 20.04 LTS
• go version 1.18.1 [1] or newer
• Installed packages make and build-essential [2] [3]
• 2 or more CPU cores Intel or AMD chipset
• At least 40GB of disk storage
• At least 4GB of memory (RAM)

Ref -
[1] https://github.com/golang/go/wiki/Ubuntu
[2] https://packages.ubuntu.com/focal/make
[3] https://packages.ubuntu.com/focal/build-essential

You can use a physical infrastructure (baremetal) or wellknown cloud providers like: DigitalOcean, AWS, Google Cloud Platform, among others

Build the tgrade binary

The tgrade binary is the backbone of the platform.
It is both blockchain node and interaction client. Therefore we use git to clone tgrade repo into our running validator

git clone https://github.com/confio/tgrade
cd tgrade
git checkout v0.10.0-rc2

Run GO install and build for the upcoming binary

make build

Move the binary to an executable path

sudo mv build/tgrade /usr/local/bin

At last, Thank you
As an official announcement, we can start the process at the moment:

• gathering the correct info,
• getting the pre-genesis file ready,
• and submitting a gen tx in a few days.

But we will ask you to recompile the binary once the final version of tgrade 0.10.0 is available.

Setting up a Genesis Tgrade Validator - PHASE 1

( to be announced ) - within 14.06 - 17.06

Initialize your genesis and configuration files

Initialize your genesis and configuration files for all validators nodes

Usage:

tgrade init [moniker] [flags]
tgrade init my-validator --chain-id tgrade-mainnet-1 --home /opt/validator/.tgrade

Import your Validator Key

We already have assigned the genesis validators for the upcoming blockchain. Therefore use the tgrade address YOU provided via Email.

Usage:

tgrade keys add <name> --recover
tgrade keys add my-validator --recover --home /opt/validator/.tgrade

Into the mnemonic(s) used for your tgrade address

Get the pre-genesis file

Get the genesis file and moved to the right location

wget https://raw.githubusercontent.com/confio/public-testnets/main/mainnet-1/config/pre-genesis.json -O ~/opt/validator/.tgrade/config/genesis.json

( this will be the case if the APP Home directory is /opt/validator/.tgrade , please change it accordingly to your system/validator)

Setup the right parameters and values on the TOML files

Please edit the config/app.toml and config/config.toml accordingly

- app.toml: set minimum-gas-prices
  minimum-gas-prices = "0.05utgd"

- config.toml: set persistent_peers and other suggested changes
  moniker = "<your validator name>"
  persistent_peers = "[email protected]:26656,[email protected]:26656,[email protected]:26656"

Create genesis txs - PHASE 2

Collect tendermint node-ids and validator info

You need to know some specifs info for your gen TX

• node-id tgrade tendermint show-node-id
• Public IP exposed to the Internet

Create genesis txs

Each validator needs to create a genesis tx, by running:

tgrade gentx my-validator 0utgd 285000000000utgd \
  --amount 0utgd \
  --vesting-amount 285000000000utgd \
  --fees 10000utgd \
  --moniker my-validator \
  --ip "<public ip>" \
  --node-id $(sudo tgrade tendermint show-node-id --home /opt/validator/.tgrade) \
  --chain-id tgrade-mainnet-1 \
  --home /opt/validator/.tgrade

vesting-amount, node-id, and home values are just examples, please change it accordingly to your system/validator

Upload your Gen_TX

The above will create a gentx file. We are going to need it for the genesis collect.

1. Fork the repo: https://github.com/confio/public-testnets , clicking on fork, and choose your account
2. Clone your fork copy to your local machine
3. Copy the gentx file into ../mainnet-1/config/gentx/
4. Commit and push the repo
5. Create a pull request from your fork to the main repo
6. Inform us on the discord channel

git clone https://github.com/<your_github_username>/public-testnets
cd public-testnets
git add public-testnets/mainnet-1/config/gentx/
git commit -am "<your validator name> - gentx - comment"
git push origin master

Start your Validator - PHASE 3

( to be announced ) - within 22.06 - 24.06
