This chapter is the simplest, mainly about installing node js、npm、near-cli。 Then use near cli commands

update apt

# update apt package
sudo apt update && sudo apt upgrade -y

install node & npm

curl -sL https://deb.nodesource.com/setup_18.x | sudo -E bash -  
sudo apt install build-essential nodejs
PATH="$PATH"

check version

ubuntu@ip-172-26-8-107:~$ node -v
v18.6.0

ubuntu@ip-172-26-8-107:~$ npm -v
8.13.2

install near-cli

# global install
sudo npm install -g near-cli

command

The environment will need to be set each time a new shell is launched to select the correct network.

GuildNet
TestNet
MainNet
Shardnet (this is the network we will use for Stake Wars)

# set network tmp env
export NEAR_ENV=shardnet

you can also set env profile

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

# source
source ～/.bashrc

near proposals

A proposal by a validator indicates they would like to enter the validator set, in order for a proposal to be accepted it must meet the minimum seat price.

This challenge is focused on deploying a node (nearcore), downloading a snapshot, syncing it to the actual state of the network, then activating the node as a validator.

Precondition

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

#  install lscpu
apt install util-linux

lscpu | grep -P '(?=.*avx )(?=.*sse4.2 )(?=.*cx16 )(?=.*popcnt )' > /dev/null \
>   && echo "Supported" \
>   || echo "Not supported"

Installation dependency

Developer tools

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

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 Rust & Cargo

Note: if the version of rust1.59.0 is installed by default on this computer, you need to install the new version to make the environment variables take effect

ubuntu@ip-172-26-8-107:~$ /bin/rustc -V
rustc 1.59.0

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

please，input y，continue install rust please input 1,continue install。

source $HOME/.cargo/env

Clone source code

git clone -b master https://github.com/near/nearcore

Build

In the nearcore folder run the following commands:

cargo build -p neard --release --features shardnet

build will take some time. Wait a moment。finish。neardin target/releasedir

ubuntu@ip-172-26-8-107:~/code/nearcore$ ls target/release/
build  deps  examples  incremental  neard  neard.d

Init work dir

In order to work properly, the NEAR node requires a working directory and a couple of configuration files. Generate the initial required working directory by running:

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

update config.json

rm ~/.near/config.json
wget -O ~/.near/config.json https://s3-us-west-1.amazonaws.com/build.nearprotocol.com/nearcore-deploy/shardnet/config.json
sed -e 's/"archive": false/"archive": true/' -i config.json

Get latest snapshot

Install AWS Cli

sudo apt-get install awscli -y

Download snapshot

cd ~/.near
# download
aws s3 --no-sign-request cp s3://build.openshards.io/stakewars/shardnet/data.tar.gz . 
# tar 
tar -xzvf data.tar.gz
# remove snapshot
rm -rf data.tar.gz

Run the node

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

The node is now running you can see log outputs in your console. Your node should be find peers, download headers to 100%, and then download blocks.if 100%,you can stop node。

Activating the node as validator

login

near login

Then copy the displayed link to the browser, open it, and then log in to Shardnet wallet. If there is no account, create one, After clicking confirm, return to the near login console interface and pause there. We need to enter the account ID, enter, and login success. Let's check whether the credentials exist. There should be a ${accountid} JSON file

ubuntu@ip-172-26-8-107:~/code/nearcore$ ls ~/.near-credentials/shardnet/
eth.shardnet.near.json

cp the credentials json filevalidator_key.json

# XXX is the file just generated after login successful
cp ~/.near-credentials/shardnet/xxx.json ~/.near/validator_key.json

editvalidator_key.json

Edit “account_id” => xx.factory.shardnet.near, where xx is your PoolName
Change private_key to secret_key

File content must be in the following pattern: if you accountID is abc.shardnet.near，the validator_key.json account_id filed is abc.factory.shardnet.near。

{
  "account_id":"xxx.factory.shardnet.near",
  "public_key":"ed25519:Coqwefqumi1yCgAUAUfuWtzJXbHEzebS5RRPjvhqMbpV",
  "secret_key":"ed25519:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
}

start validator node create neard systems service

sudo vi /etc/systemd/system/neard.service

Paste：

003

Deploy a new staking pool for your validator. Do operations on your staking pool to delegate and stake NEAR.

create stake pool

near call factory.shardnet.near create_staking_pool '{"staking_pool_id": "<pool id>", "owner_id": "<accountId>", "stake_public_key": "<public key>", "reward_fee_fraction": {"numerator": 1, "denominator": 100}, "code_hash":"DD428g9eqLL8fWUxv8QSpVFzyHi1Qd16P8ephYCTmMSZ"}' --accountId="<accountId>" --amount=30 --gas=300000000000000

pool_id：if you accountID is abc.shardnet.near,the pool_id is abc
owner_id： you accountID is abc.shardnet.near,the accountId is abc.shardnet.near
public key：field public_key field in validator_key.json
accountId：The SHARDNET account deploying and signing the mount tx. Usually the same as the Owner ID.
reward_fee_fraction：fee，1/100，1%

example：

near call factory.shardnet.near create_staking_pool '{"staking_pool_id": "jiangwei", "owner_id": "jiangwei.shardnet.near", "stake_public_key": "ed25519:Coqwefqumi1yCgAUAUfuWtzJXbHEzebS5RRPjvhqMbpV", "reward_fee_fraction": {"numerator": 1, "denominator": 100}, "code_hash":"DD428g9eqLL8fWUxv8QSpVFzyHi1Qd16P8ephYCTmMSZ"}' --accountId="jiangwei.shardnet.near" --amount=30 --gas=300000000000000

Check whether your verifier is displayed in the block browser ShardNet Validator Node

Stake

use jiangwei.shardnet.near account stake 999 NEAR to jiangwei.factory.shardnet.near.

accountID=jiangwei.shardnet.near
amount=999
near call jiangwei.factory.shardnet.near  deposit_and_stake --amount $amount --accountId $accountID --gas=300000000000000

Ping

A ping issues a new proposal and updates the staking balances for your delegators. A ping should be issued each epoch to keep reported rewards current

near call <staking_pool_id> ping '{}' --accountId <accountId> --gas=300000000000000

we can create cron job

near_ping.sh

ubuntu@ip-172-26-8-107:~$ cat near_ping.sh 
NEAR_ENV=shardnet near call jiangwei.factory.shardnet.near ping '{}' --accountId jiangwei.shardnet.near --gas=300000000000000

cron job

ubuntu@ip-172-26-8-107:~$ crontab -e
# auto Ping once every 5 minutes
*/5  * * * * nohup ~/near_ping.sh >> ~/near_ping.log 2>&1 &

004

Becoming a verifier is not immediately visible. After creating a take pool, the status should be proposal and being added: If everything is normal, the next epoch will be effective. At present, it is about 2 hours an epoch. if desplay Validator, it is effective
