Block and unblock a user

:::tip Rewards
Upon completing this challenge, you will be rewarded 50 Desmos Tokens.

Please note that in order to prevent spam, you will receive the reward just for the first block and unblock you create. No tokens will be awarded for later blocks/unblocks. :::

Starting from version v0.12.0, you can now block and unblock users.

Blocking and unblocking your first user

:::tip Requirements
To block or unblock a user, you will need their address.
:::

Blocking a user

To block a user, you have to use the following command:

desmoscli tx relationships block <User address> <Subspace> <(Optional) Reason> \
  --from <your-key-name> --yes \
  --chain-id <chain-id>

Here's an example of such command:

desmoscli tx relationships block \
  desmos1j2hyp3mzrxfhdkxzyvyqw9atu2s3smt89mklxs \
  4e188d9c17150037d5199bbdb91ae1eb2a78a15aca04cb35530cccb81494b36e \
  "I don't like you" \
  --from jack --yes \
  --chain-id morpheus-10000

Once you run that command you will be asked to type the password you've chosen during the setup and after having inserted it properly you should see something like this:

height: 0
txhash: E4920B61BFCFB935124FFC22BC04C1D5619943B138C87913E6EBCF2B5E892290
codespace: ""
code: 0
data: ""
rawlog: '[]'
logs: []
info: ""
gaswanted: 0
gasused: 0
tx: null
timestamp: ""

To make sure the transaction has been processed successfully, you can query it using the following command:

desmoscli query tx <hash> --trust-node --output json

# Example
# desmoscli query tx E4920B61BFCFB935124FFC22BC04C1D5619943B138C87913E6EBCF2B5E892290 \
  --trust-node --output json

This will return you the JSON representation of the transaction itself.

Unblocking a user

To unblock a user, you have to use the following command:

desmoscli tx relationships unblock <User address> <Subspace> \
  --from <your-key-name> --yes \
  --chain-id <chain-id>

Here's an example of such command:

desmoscli tx relationships unblock \
  desmos1j2hyp3mzrxfhdkxzyvyqw9atu2s3smt89mklxs \
  4e188d9c17150037d5199bbdb91ae1eb2a78a15aca04cb35530cccb81494b36e \
  --from jack --yes \
  --chain-id morpheus-10000

Once you run that command you will be asked to type the password you've chosen during the setup and after having inserted it properly you should see something like this:

height: 0
txhash: E4920B61BFCFB935124FFC22BC04C1D5619943B138C87913E6EBCF2B5E892290
codespace: ""
code: 0
data: ""
rawlog: '[]'
logs: []
info: ""
gaswanted: 0
gasused: 0
tx: null
timestamp: ""

To make sure the transaction has been processed successfully, you can query it using the following command:

desmoscli query tx <hash> --trust-node --output json

# Example
# desmoscli query tx E4920B61BFCFB935124FFC22BC04C1D5619943B138C87913E6EBCF2B5E892290 \
  --trust-node --output json

This will return you the JSON representation of the transaction itself.

Getting the reward

:::warning Two transactions required
To get this challenge's reward, you need to submit two transaction hashes, and not only one. One needs to be the one returned after you blocked a user, and the other one after you unblocked a user.
Failing to provide either one of the two will result in no rewards given.
:::

After you've blocked and unblocked a user, to make sure you receive your reward please follow this procedure:

  1. Create a fork of this repo inside your private GitHub profile.
    If you do not know how to do it, follow the GitHub fork guide.

  2. Pull the fork locally:

    git clone https://github.com/<your-name>/primer.git ~/desmos-primer
cd ~/desmos-primer

  3. Make sure your fork is up to date with the Primer repository:

    git remote add upstream https://github.com/desmos-labs/primer.git
git fetch upstream
git rebase upstream/master

  4. Create a file named after your GitHub username containing the first transaction hash:

    echo "<tx-hash>" >> ./phase-6/submissions/block-user/<your-github-name>

# Example
# echo "E4920B61BFCFB935124FFC22BC04C1D5619943B138C87913E6EBCF2B5E892290" >> ./phase-6/submissions/block-user/RiccardoM

  5. Create a file named after your GitHub username containing the second transaction hash:

    echo "<tx-hash>" >> ./phase-6/submissions/unblock-user/<your-github-name>

# Example
# echo "E4920B61BFCFB935124FFC22BC04C1D5619943B138C87913E6EBCF2B5E892290" >> ./phase-6/submissions/unblock-user/RiccardoM

  6. Commit the changes, push them to your forked repo and create a pull request. If you do not know how to create one, refer to the GitHub Pull Requests guide.
