Learn the Bitcoin Ordinal NFT Casting tutorial to prepare for the next one

Bitcoin eco-protocol Ordinal is all the rage these days, mainly because of the wealth effect. After all, it's hard not to feel excited when a Punk can buy a btc at a very low cost. However, it is believed that many people are far less adept at using the Bitcoin network than Ethereum, so BlockBeats goes through the process and shares the tutorial with you. Although this Bitcoin Punk mint is over, this kind of learning is definitely useful and you can prepare for the next mint and try it at the next mint.

Set up a wallet

The first thing you need is a Bitcoin address that accepts messages. The sparrow wallet is generally recommended. Let's set it up step by step. First,Click DownloadAn installation package suitable for your pc environment. The following screenshot is from github gist. No obstacles were found after BlockBeats testing.

Once installed, name the wallet, whatever you want, and click create.

Then change the script type to taproot (p2tr) and click on new or imported software wallet.

Select 12 mnemonics and click generate new. 12 mnemonics will be generated automatically. Remember them and rewrite them later. Remember to click confirm backup.

Then click create keystore.

Click import keystore.

Then click apply, if you'd like to add a password to your wallet.

So a new bitcoin wallet is set up with address as your address, which you'll need later in mint.

Use bot

Normally this step requires a node, but apparently this is something that most people don't have, so a developer developed itOrdinalsbotEasy to use, mainly for the text class and picture class NFT. The downside is that the bot sometimes goes down. There will be other bots coming out, like the one in gamma.

After completing the wallet setup, you need to goBitcoin Punks websitePick the NFT that hasn't been cast yet (you can put a picture anywhere, of course), pick one, and write down the number. In a web browser input "https://cryptoPunks.app/public/images/cryptoPunks/Punk * * * * number (id) in PNG", right click, save as to save the image.

Log in the bot website and fill in the relevant information according to the instructions below. It is suggested that the commission should be pulled directly to improve the casting success rate. The cost will increase some, and the congestion will probably be more than 30 knives.

After clicking to generate payment Invoice, the payment Invoice code will pop up on the webpage. You can choose to make payment through Lightning network or Bitcoin regular network. In theory a lightning network would be faster. After the payment is completed, wait for the transfer confirmation. (Note: The payment wallet can be different from the wallet address that receives the NFT.)

After the transfer is confirmed, how to check whether the casting is successful? passableBitcoin Punks websiteFollow the cast ID and click on the "ORD" link to go to the NFT details page on the Ordinals website. If the address is the receiving address you set, congratulations, the cast is successful.

Matters needing attention

asIn the previous articleThe Ordinals protocol has a numbering scheme that supports the tracking and transmission of a single Bitcoin's smallest unit, Satoshi, numbering different Satoshi in the order they were mined and moving them from transaction input to transaction output on a first-in, first-out basis. Each Satoshi has a unique number that serves as an ID and can be tracked or traded individually. On this basis, data (such as images, text, SVG, HTML, etc.) is written into each Satoshi, completing the transformation of Satoshi from a "bitcoin minimum unit" to a "bitcoin NFT".

Therefore, it can be said that the current Bitcoin NFT is stored on UTXOs that record transaction information. Therefore, after successfully minting Bitcoin NFT, it is necessary to freeze the UTXO that holds the NFT information in the wallet, so as to ensure that it will not be paid out in the later transfer process.
