Follow the tutorial 1 quickly minted the first NFT0, with following concise steps:

  1. chia wallet nft create
  2. chia wallet nft mint
  3. chia wallet nft list
  4. chia wallet nft add_uri

Then, I got NFT like this:

(P.S.: I suffix the coin id/name in the heading to avoid getting lost.)

II. Singleton launcher 0x11f40a80

  1. Make sure you are on testnet10,
  2. and enter the launcher coin ID above to the input box and search.

You will get detail about this coin.

  1. You can clearly find that this coin is a singleton launcher.
  2. Let’s find the next coin.

Hint: You can navigate to the next coin easily with this navigation.

III. Singleton top layer 0x5de5d491

You can find this coin much more complex, like this:

There are 3 layers like this:

  • singleton top layer v1.1
    • nft state layer
      • p2 delegated puzzle (standard xch transfer module)

  1. Top layer is singleton top layer.

  2. First argument includes mod hash, launcher id and launcher puzzle hash.

  3. Second layer holds the state.

  4. Meta data is the second argument. Don’t be scared by the magic number, you can get help in place like this:

  5. Standard XCH transfer module for approving this transaction.

IV. Next coin for ownership and modification 0x56b6e63c

The puzzle of next coin is almost same as previous one, only the innermost puzzle changes for ownership transfer.

In my understanding, previous coin is acting like a hint which avoids concealing the information in the puzzle we plan to disclose(to show as a picture or other).

V. Solution for the modification coin 0x56b6e63c

10.png

When this coin is consumed, it means the NFT is planned to change something, you can see change add_uri in the solution.

After executed, it will act like a standard NFT coin.

VI. End

That’s all for today. Have fun!
