A. INSTALL

Run a light validator

Light validator is a type of node that performs availability validation solely through data sampling without participating in data sharding synchronization. It is also part of a consensus network. These nodes can participate in voting but will not act as proposers to generate new blocks. You can follow the steps below to start a light validator:

  1. Download the light validator binary package from:

    or simply run from your command line terminal:

    curl -O https://dill-release.s3.ap-southeast-1.amazonaws.com/linux/dill.tar.gz

  2. Extract the package:

    tar -xzvf dill.tar.gz && cd dill

    sample output

    ubuntu@ip-xxxx:~$ curl -O https://dill-release.s3.ap-southeast-1.amazonaws.com/linux/dill.tar.gz
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100 64.5M  100 64.5M    0     0  6655k      0  0:00:09  0:00:09 --:--:-- 8072k
ubuntu@ip-xxxx:~$ tar -xzvf dill.tar.gz && cd dill
dill/
dill/validators.json
dill/genesis.ssz
dill/dill_validators_gen
dill/start_light.sh
dill/dill-node
ubuntu@ip-xxxx:~/dill$

  3. Generate validator keys using the key generation tool:

    ./dill_validators_gen new-mnemonic --num_validators=1 --chain=andes --folder=./

    sample output

    ubuntu@ip-xxxx:~/dill$ ./dill_validators_gen new-mnemonic --num_validators=1 --chain=andes --folder=./

***Using the tool on an offline and secure device is highly recommended to keep your mnemonic safe.***

Please choose your language ['1. العربية', '2. ελληνικά', '3. English', '4. Français', '5. Bahasa melayu', '6. Italiano', '7. 日本語', '8. 한국어', '9. Português do Brasil', '10. român', '11. Türkçe', '12. 简体中文']:  [English]: 3
Please choose the language of the mnemonic word list ['1. 简体中文', '2. 繁體中文', '3. čeština', '4. English', '5. Italiano', '6. 한국어', '7. Português', '8. Español']:  [english]: 4
Create a password that secures your validator keystore(s). You will need to re-enter this to decrypt them when you setup your Dill validators.:
Repeat your keystore password for confirmation:
The amount of DILL token to be deposited(2500 by default). [2500]:
This is your mnemonic (seed phrase). Write it down and store it safely. It is the ONLY way to retrieve your deposit.

Creating your keys.
Creating your keystores:	  [####################################]  1/1
Verifying your keystores:	  [####################################]  1/1
Verifying your deposits:	  [####################################]  1/1

Success!
Your keys can be found at: ./validator_keys

Press any key.
ubuntu@ip-xxxx:~/dill$

    This will generate the validator keys and save them in ./validator_keys directory

    ubuntu@ip-xxxxx:~/dill$ ls -ltr ./validator_keys
total 8
-r--r----- 1 ubuntu ubuntu 710 Jul 13 08:06 keystore-m_12381_3600_0_0_0-xxxxxx.json
-r--r----- 1 ubuntu ubuntu 706 Jul 13 08:06 **deposit_data-xxxx.json**
ubuntu@ip-xxxxx:~/dill$

  4. Import your keys to your keystore:

    ./dill-node accounts import --andes --wallet-dir ./keystore --keys-dir validator_keys/ --accept-terms-of-use

    During this process, you need to configure and save your keystore password.

    sample output

    
ubuntu@ip-xxxxx:~/dill$ ./dill-node accounts import --andes --wallet-dir ./keystore --keys-dir validator_keys/ --accept-terms-of-use

[2024-07-13 08:08:44]  INFO accounts: Imported accounts [xxxxxx], view all of them by running `accounts list`
ubuntu@ip-xxxxx:~/dill$

  5. Write the password you configured in the previous step into a file:

    echo <my-password> > walletPw.txt

  6. Start the light validator node

    Here you need to specify your password file as a startup parameter. You can start the program with the following command:

    ./start_light.sh -p <password-path>

    sample output

    ubuntu@xxxxx:~/dill$ ./start_light.sh -p walletPw.txt
Option --pwdfile, argument 'walletPw.txt'
Remaining arguments:
using password file at walletPw.txt
start light node
start light node done
ubuntu@xxxxx:~/dill$ nohup: redirecting stderr to stdout

  7. to check if the node is up and running and there should be one dill process running:

    ps -ef | grep dill

sample output

ubuntu      1981       1 86 08:09 pts/0    00:00:43 /home/ubuntu/dill/dill-node --light --embedded-geth --datadir /home/ubuntu/dill/light_node/data/beacondata --genesis-state /home/ubuntu/dill/genesis.ssz --grpc-gateway-host 0.0.0.0 --initial-validators /home/ubuntu/dill/validators.j
...

Staking

  • visit https://staking.dill.xyz/

  • upload deposit_data-*.json

    • you can use scp to copy to local or simply ubuntu@ip-xxx:~/dill$ cat ./validator_keys/deposit_data-xxxx.json to get the content and make a copy in your local machine

image

  • Connect to MetaMask，make sure you have enough balance（>2500 DILL）

image

  • Send deposit，using MetaMask to send a deposit transaction

B. MANAGEMENT:

1. Services Management

cd $HOME/dill

1.1 Check health node

./health_check.sh -v

1.2 Stop node

ps -ef | grep dill-node | grep -v grep | awk '{print $2}' | xargs kill

1.3 Start node

./start_light.sh -p walletPw.txt

1.4 Check logs

tail -f -n 100 $HOME/dill/light_node/logs/dill.log

1.5 Check on Explorer

Copy your pubkey in file deposit_data-xxxx.json and search it on explorer: https://andes.dill.xyz/validators?p=1&ps=1000

2. Fix port 8080 (change to 8081)

2.1 Stop node

cd $HOME/dill
ps -ef | grep dill-node | grep -v grep | awk '{print $2}' | xargs kill

2.2 Update file (use port 8081)

rm -rf $HOME/dill/health_check.sh && rm -rf $HOME/dill/start_light.sh && \
wget -O  $HOME/dill/start_light.sh https://raw.githubusercontent.com/nodesynctop/Dill/main/start_light.sh && \
wget -O  $HOME/dill/health_check.sh https://raw.githubusercontent.com/nodesynctop/Dill/main/health_check.sh && \
chmod +x health_check.sh && chmod +x start_light.sh

2.3 Start node

./start_light.sh -p walletPw.txt
