Create a post

:::tip Note
Upon completing this challenge, you will be rewarded 20 Desmos Tokens.

Please note that in order to prevent spam, you will receive the reward just for the first post you create. No tokens will be awarded for later posts.
:::

Inside Desmos, posts are the way that users have to share publicly whatever they want.

You can see posts much like tweets on Twitter, as they have the same functionality: they allow you to write what you wish (without any length limitation) and they are publicly visible to all the Desmos users.

The only difference with tweets is that once you've created a Desmos post you will not be able to delete it! This is due to the blockchain's intrinsic characteristic of being immutable: each transaction that is performed cannot be undone.

Creating your first post

After you've followed the setup and you've created your Desmos account using the desmoscli keys command, you are ready to create your first post. To do so, run the following command:

desmoscli tx posts create "<Subspace>" "<Message>" true --from <your-key-name> --yes 

# Example
# desmoscli tx posts create "desmos" "Hello world!" true --from jack --yes

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: 89243E31ED012CC0AE541C56983946E4BBE1D830DF71B2D0E2EB79CB37BE5231
code: 0
data: ""
rawlog: '[{"msg_index":0,"success":true,"log":"","events":[{"type":"message","attributes":[{"key":"action","value":"create_post"}]}]}]'
logs:
- msgindex: 0
  success: true
  log: ""
  events:
  - type: message
    attributes:
    - key: action
      value: create_post
info: ""
gaswanted: 0
gasused: 0
codespace: ""
tx: null
timestamp: ""
events: []

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

desmoscli query tx <hash> --output json

# Example
# desmoscli query tx 89243E31ED012CC0AE541C56983946E4BBE1D830DF71B2D0E2EB79CB37BE5231 --output json

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