Gravity Protocol:
Resyncing the node
Witnesses:
1. To avoid missing the blocks, witnesses have to use the backup node
Make sure that your backup node is running.
2. In the cli_wallet change your witness signing key to backup key
--- Code: ---update_witness g1234r1234v1234z1234 "my url" ZGV...backupSigningPublicKey true
--- End code ---
Make sure that block production continued from your witness
3. Restart the main node
docker:
--- Code: ---docker-compose down
docker-compose up -d
--- End code ---
without docker:
--- Code: ---Ctrl+C
./witness_node --data-dir=data --resync-blockchain
--- End code ---
Wait for synchronization after update
4. Switch your witness back to its main signing key
--- Code: ---update_witness g1234r1234v1234z1234 "my url" ZGV...mainSigningPublicKey true
--- End code ---
Make sure that block production continued from your witness
5. Restart the backup node the same way as the main
Non-witnesses:
1. Restart the node
docker:
--- Code: ---docker-compose down
docker-compose up -d
--- End code ---
without docker:
--- Code: ---Ctrl+C
./witness_node --data-dir=data --resync-blockchain
Wait for synchronization after update
--- End code ---

Gravity Protocol:
How to update Gravity Protocol node
We’re going to learn how to update Gravity Protocol node.
* First, we’ll go to the node’s directory.
--- Code: ---cd gravity-testnet-docker
--- End code ---
* Here we’ll stop our node.
--- Code: ---sudo docker-compose down
--- End code ---
* Then we’ll receive the update from github.
--- Code: ---git pull origin
--- End code ---
* And new versions of packages from Dockerhub.
--- Code: ---sudo docker-compose pull
--- End code ---
* Now we’ll run the node in daemon mode.
--- Code: ---sudo docker-compose up -d
--- End code ---
* If you prefer, you can display current sync status on the screen.
--- Code: ---sudo docker-compose logs — tail 10 -f
--- End code ---
* To hide the logs, press *Ctrl+Z.

Gravity Protocol:
How to make proposals and to edit a blockchain configuration
We’re going to learn how to make proposals and to edit a blockchain configuration.
* First we’ll open cli-wallet when the node is launched.
--- Code: ---sudo docker-compose exec gravity_node cli_wallet -w /var/lib/gravity/wallet.json
--- End code ---
* Then we’ll unlock the wallet.
--- Code: ---unlock 1234567
--- End code ---
* And now we’ll get to work.
* We’ll get current configuration values:
--- Code: ---get_global_properties
--- End code ---
* We’ll make a proposal to change the interval between the blocks using the template:
--- Code: ---propose_parameter_change [from account] [time, the value must be greater than CURRENTTIME + committee_proposal_review_period and lower than CURRENTTIME + maximum_proposal_lifetime] {json with the new values} true
--- End code ---
* For example:
--- Code: ---propose_parameter_change “g2090i8190e9280o7900” “2018–06–13T17:28:00” {“block_interval”: 3} true
--- End code ---
* Now we’ll get the number of proposal id.
--- Code: ---get_account_history “g2090i8190e9280o7900” 1
2018–06–13T17:00:20 proposal_create_operation g2090i8190e9280o7900 fee: 20.00007 ZGV result: 1.10.1
--- End code ---
* And we’ll vote.
--- Code: ---approve_proposal g2090i8190e9280o7900 1.10.1 {“active_approvals_to_add” : [“g2090i8190e9280o7900”]} true
--- End code ---
* Now we’ll close the cli-wallet using Ctrl+C
And we’ll change the fees:
* First we’ll get current values of the configuration
--- Code: ---get_global_properties
--- End code ---
* Then we’ll make a proposal to change the fees.
--- Code: ---propose_fee_change “g2090i8190e9280o7900” “2018–06–13T04:32:00” {0 : {“fee”: 1, “price_per_kbyte”: 0,1}, 34 : {“fee”: 10000000}} true
--- End code ---
* Now we’ll get the number of proposal id.
--- Code: ---get_account_history “g2090i8190e9280o7900” 1
2018–06–13T17:00:20 proposal_create_operation g2090i8190e9280o7900 fee: 20.00007 ZGV result: 1.10.1
--- End code ---
* And vote:
--- Code: ---approve_proposal g2090i8190e9280o7900 1.10.1 {“active_approvals_to_add” : [“g2090i8190e9280o7900”]} true
--- End code ---

Gravity Protocol:
Comittee Memember Registration Tutorial
We’ll be learning how to create a member of the committee from an account.
Video instrustion is here.
* To begin, we need to open the file with the program node.
--- Code: ---cd gravity-testnet-docker
--- End code ---
* Now, let’s start our node with demonization.
--- Code: ---sudo docker-compose up -d
--- End code ---
* Next, run the cli-wallet with extra parameters.
--- Code: ---sudo docker-compose exec gravity_node cli_wallet -w /var/lib/gravity/wallet.json
--- End code ---
* At this time, we’ll create a password for the wallet.
--- Code: ---set_password password
--- End code ---
* Unblock the wallet and we’ll be sent into our account.
--- Code: ---unlock password
--- End code ---
* Here, we’ll import our account.
--- Code: ---import_key “your-account” “your-active-private-key”
--- End code ---
* Now that we’ve done this, we have a lifetime membership for this account,
--- Code: ---upgrade_account “account” true
--- End code ---
* From this account we’ll be creating a member of the committee.
--- Code: ---create_committee_member “account” “url” true
--- End code ---
* Execute the following command, an example is in the video description.
* Now close the cli-wallet using the keyboard shortcut Ctrl+C.
* Now your account is a candidate to be a member of the committee.
* All that is left to do is convince people to vote for you.
If you’ve already created a witness node, you can skip the password setting steps for the wallet, import the account and purchase a lifetime membership.

Gravity Protocol:
Turn a node into a witness node
We’re going to turn a node into a witness node.
Video instructions you can find here.
* First, open node’s directory.
--- Code: ---cd gravity-testnet-docker
--- End code ---
* Then, run the node in daemon mode, and run the cli-wallet with advanced settings.
--- Code: ---sudo docker-compose up -d
sudo docker-compose exec gravity_node cli_wallet -w /var/lib/gravity/wallet.json
--- End code ---
* Next, Set a password for the wallet and unblock the wallet.
--- Code: ---set_password password
unlock password
--- End code ---
* Import your account in the wallet.
--- Code: ---import_key “your-account” “your-active-private-key”
--- End code ---
* Here’s where you’ll get a lifetime membership, and then create a witness.
--- Code: ---upgrade_account “account” true
create_witness “account” “url” true
--- End code ---
* Now you’ll need to get your witness-ID.
--- Code: ---get_witness “account”
--- End code ---
* As you can see, the witness-ID for this specific account is “1.6.*” You’re going to want to memorize it or write it down. There is also a public key for signing blocks which also needs to be saved.
* Now you can derive a private key using the public key, save the private key as well.
--- Code: ---get_private_key [public signing key]
--- End code ---
(without quote)
* Now close the cli-wallet using Ctrl+C.
* After that, you’ll need to edit the config.ini file.
--- Code: ---sudo nano ./data/config.ini
--- End code ---
* Add your witness-ID, and replace the keys.
* Don’t forget to delete the sharp symbol (#) in front of witness-id to turn the comment line into a code line.
* After you’ve added your witness-ID and replaced the keys, press Ctrl+X.
* Then press Y to save the changes.
* Now you’ll need to restart the node. For that, use the docker-compose down and docker-compose up commands.
--- Code: ---sudo docker-compose down
sudo docker-compose up -d
--- End code ---
* And there you have it, a running witness node!
* Now, all you have to do is convince people to vote for you.
