Atlantis Testnet Source Code

Pre-requisites:

Go version 1.18 Ubuntu 22.04 Make GCC

Pre-requisite step

Install Golang:

Install latest go version https://golang.org/doc/install

wget -q -O - https://raw.githubusercontent.com/canha/golang-tools-install-script/master/goinstall.sh | bash -s -- --version 1.18
source ~/.profile

To verify that Golang installed

go version

It should return go version go1.18 linux/amd64

Install Make to compile the code

sudo apt install make

Install GCC in case GCC is not yet installed

sudo apt-get install gcc

Compile the code

make install

This will create a blockxd file in the /root/go/bin directory

Run a Node

To run a node, edit the init.sh file and change the Moniker name to whatever you want your node to be named.

chmod +x init.sh
./init.sh

How to add blockxd path for it to be accessible system-wide

In the example below, blockxd is in /root/go/bin

export PATH=/root/go/bin:$PATH
source ~/.bashrc

How to add a key

blockxd keys add <your key name> --keyring-backend file --algo eth_secp256k1
# e.g.  blockxd keys add mykey --keyring-backend file --algo eth_secp256k1

It will prompt you to create a keyring passphrase, make sure you remember it as you're going to need this for every transactions. After entering the passphrase, it will give you your address together with a recovery phrase, make sure to have a copy of it. You can use this passphrase to import your key/wallet to another wallet like Metamask.

How to become a validator using Ubuntu 22.04

Make sure to request for some BCX tokens first from the BCX Team. You will have a receiving address once you created a key from the previous instruction. Open the validator.sh file and change the values there depending on your preference

chmod +x validator.sh
./validator.sh

Notes if starting own chain

Make sure that the voting power of 1 validator does not reach more than 30% to avoid potential too much dependency of the chain to a single node only.
Dont use the genesis.json file in this repository and let it create its own genesis.json file
persistent_peer is important in the config but it is safer to have some nodes in the seed cofiguration of the config file located in .blockxd/config/config.toml file

Submitted Proposals

Proposals were submitted for this Atlantis Testnet in order to improve the chain. For this testnet, we submitted the proposals below. The files slash.json and metadata.json is also located in this repo:

Change Slashing Window The Slashing window dictates how many blocks can a validator miss before they get jailed which slashes their earnings. The previous setting was 100 blocks and with a block time of around 1 second, it only gives the validator around 2 minutes to upgrade their server or have a downtime. The submitted proposal increased the window to 40,000 blocks giving enough time for validators to perform maintenance in their servers. Below is the command used

./blockxd tx gov submit-proposal param-change slash.json --from node1 --chain-id blockx_50-1 --gas 1000000

Register Coin for metadata This metadata proposal was submitted in order for Ping Explorer and may also include future dapps to be able to recognize the denominations of Atlantis Testnet which is abcx and bcx with BCX = 1e18 abcx. Below is the command used

./blockxd tx gov submit-proposal register-coin metadata.json --from node1 --chain-id blockx_50-1 --gas 2000000 --title "BCX Metadata proposal" --description "For Ping UI to be able to detect the number of decimals BCX has"
