#How to set up a Shardnet Node for NEAR STAKEWARS

#Get a vps server at digitalocean with this link https://m.do.co/c/3d3f5749db15, 100$ in free credits to buy server

#once yours vps is ready,you can ssh login with the droplet console or you can use mobaxterm to ssh login, download mobaxterm here https://mobaxterm.mobatek.net/download.html

#now register with this form for participating in the testnet https://nearprotocol1001.typeform.com/to/Z39N7cU9

#Challenge 001#

#make sure the linux machine is up-to-date

sudo apt update && sudo apt upgrade -y

#Before you start, you may want to confirm that your machine has the right CPU features.

#install Node JS and NPM

curl -sL https://deb.nodesource.com/setup_18.x | sudo -E bash - 

sudo apt install build-essential nodejs 

PATH="$PATH"

#install NEAR-CLI

npm install -g near-cli

#Set up the environment

export NEAR_ENV=shardnet

echo 'export NEAR_ENV=shardnet' >> ~/.bashrc

#Challenge 002#

#Install developer tools

sudo apt install -y git binutils-dev libcurl4-openssl-dev zlib1g-dev libdw-dev libiberty-dev cmake gcc g++ python docker.io protobuf-compiler libssl-dev pkg-config clang llvm cargo

#Install Python pip

sudo apt install python3-pip

#Set the configuration

USER_BASE_BIN=$(python3 -m site --user-base)/bin

export PATH="$USER_BASE_BIN:$PATH"

#Install Building env

sudo apt install clang build-essential make

#Install cargo and rust

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

source $HOME/.cargo/env

#Now download and build binary

git clone https://github.com/near/nearcore 
cd nearcore 
git fetch 
git checkout 1897d5144a7068e4c0d5764d8c9180563db2fe43
cargo build -p neard --release --features shardnet

#check the version

~/nearcore/target/release/neard --version

#now you have to initialize the working directory, delete old files and download new config file and new genesis.json

~/nearcore/target/release/neard --home ~/.near init --chain-id shardnet --download-genesis 

rm ~/.near/config.json ~/.near/genesis.json

wget -O ~/.near/config.json https://s3-us-west-1.amazonaws.com/build.nearprotocol.com/nearcore-deploy/shardnet/config.json 
wget -O ~/.near/genesis.json https://s3-us-west-1.amazonaws.com/build.nearprotocol.com/nearcore-deploy/shardnet/genesis.json

#Run the node

cd ~/nearcore
./target/release/neard --home ~/.near run

#you can see log outputs in your console. Your node should be able to find peers, download headers to 100%, and then download blocks.

#Activating the node as validator

#Now you will need to create a wallet https://wallet.shardnet.near.org/

#Authorize Wallet Locally

near login

#Grant Access to Near CLI

#paste your account id,e.g johnpaulnodes.shardnet.near

#you will see this, its fine

#now paste your account id in the Cli and press ENTER

#Copy your wallet json and make some changes

cd ~/.near-credentials/shardnet/
cp <wallet.json> ~/.near/validator_key.json

#NOTE:<wallet.json> ---> is your wallet name file e.g in mine johnpaulnodes.shardnet.near.json

#you should be able to open this file,copy the content

#now do this

nano validator_key.json

#then paste the content here, then edit the account ID and Private Key parameter accordingly

#should look like this

#File content must be in the following pattern

{
"account_id":"johnpaulnodes.factory.shardnet.near",
"public_key":"ed25519:72wzgPZgDx2SgE7Nffd6xfXSe4RNv57JE2ZXZ8xGH",
"secret_key":"ed25519:55Xbx9zd7pbjDjmmWhMav7ozmreJWyYyiKBVFboG8UjCegUQkxH8bwQkeEuJHxD"
}

Secret here isn't real 🤣🤣🤣
