First Steps

You can use Taro to mint, send and receive assets, verify and export proofs as well as generate profiles to handle your portfolio.
Minting assets:
Use tarocli to begin minting your first asset.
tarocli assets mint --type normal --name beefbux --supply 1000 --meta "fantastic money"
This will add your asset to a minting queue called a batch, which allows multiple assets to be created in a single minting transaction. This saves fees and conserves blockspace. Minting a transaction to the blockchain immediately is possible by appending the flag --skip_batch to the mint command.
Inspect the newly created asset(s) by calling the command
tarocli assets list

}
The output of this command can be explained as follows:
genesis_point: The first input of the minting transaction.
name: The name of the asset as defined at its creation.
meta: The metadata as defined at its creation.
asset_id: The asset ID is a digest of the information found under asset_genesis in the format sha256(genesis_outpoint || asset_tag || asset_meta || output_index || asset_type).
output index: The output of the minting transaction where the asset will be anchored.
genesis_bootstrap_info: Similar to asset_id, this field includes all of the asset_genesis data, starting with the genesis_outpoint in reverse.
asset_type: Whether an asset is “normal” or a collectible.
amount: The quantity of this asset held by you
lock_time: An asset can be locked in time, similar to a bitcoin script
relative_lock_time: Relative locktime, analogous to bitcoin script
script_key: The key holding the Taro asset
asset_family: If the asset belongs to an asset family, its key will be listed here
chain_anchor:
tx: The raw minting transaction.
txid: The hash of the minting transaction, in reverse.
block_hash: The hash of the block that the minting transaction was included in.
anchor_output: The outpoint on the bitcoin blockchain that holds the Taro asset.
internal_key: The Taproot key that holds the outpoint containing the asset.
Generating Taro addresses:
To send assets, you will need the recipient’s Taro address. This Taro address is specific to an asset and amount, so to generate an address, the recipient needs to know an asset’s genesis_bootstrap_info, which contains the genesis_outpoint, name, meta and outpoint index. Taro address reuse should be avoided.
When generating a Taro address, the receiver will create their expected Merkle trees, and tweak a Taproot key with it. The resulting key is converted to a Taproot address, where the receiver waits for an incoming transaction.
To generate a Taro address, use the following command:
tarocli addrs new --genesis_bootstrap_info 54b5a3f38e0d1f44343422750454833408634081a465fc3339117228802cc37500000002076c656f636f696e0f66616e746173746963206d6f6e65790000000000 --amt 100

encoded: The bech32 encoded taro address.
asset_id: The asset ID of the asset that the address corresponds to.
family_key: If emission is enabled for an asset, its family key will appear here.
script_key: This key identifies the script that defines how a Taro asset may be transfered.
internal_key: The key that holds the Taro asset.
taproot_output_key: The key that is going to hold the Taproot output once it is received.

You’ll also be able to inspect this address again anytime with the command tarocli addrs query
Sending a Taro asset
To send the asset, run the command below. The sender will then generate the appropriate Merkle trees for the recipient and their change outputs, sign the Taro transaction with their internal Taro key and publish the Bitcoin transaction.
