BTQ Node CLI Wallet - Slave Keys

Here's the adapted guide for managing BTQ CLI wallets with Slave keys

BTQ Node CLI Wallet - Slave Keys

The BTQ wallet is an XMSS Merkle tree constructed using the private key to generate leaves. Each "leaf" can also generate a tree of OTS Slave keys that can be used to sign transactions. This allows further expansion of a BTQ wallet, extending the number of transactions you can process before needing to regenerate a new wallet.

To create a slaves.json file, you will need a BTQ wallet.json file and a working installation of BTQ. See the guide for creating a BTQ CLI Wallet.

Currently, the only way to generate a slaves.json file is by using the command line utility btq. This can be installed by following the BTQ Node Guide. You will need shell access and be logged into the computer running btq.

Create a slaves.json

To generate a slaves.json file, you need to be connected to an active and synced node. This can be a local node or any of the peers shown in your node's peer list. You also need a wallet to use for the slaves file.

Assuming you have a synced node running on the local computer and a wallet.json file in the local directory, you can simply enter:

btq slave_tx_generate

You will be asked a few questions. You can generate a maximum of 100 slaves with a single master OTS key, which is used to sign the slaves.json file onto the network, validating the keys.

Example prompts:

Src []: 0              # Which address to use in the wallet file. 0 is the first address.
Master []:             # Master Address
Number of slaves [0]:  # Number of slaves * OTS_key_height (e.g., for tree height 10, this * 1024)
Access type [0]:       # Enter 0 to allow transactions, 1 for secure mining only
Fee [0.0]:             # Fee to pay to broadcast this across the network.

Number of Slaves

Tree Height	Available Keys	With slaves.json
8	256	6,553,600
10	1,024	104,857,600
12	4,096	1,677,721,600
14	16,384	26,843,545,600
16	65,536	429,496,729,600
18	262,144	6.871947674×10¹²

This guide ensures you can effectively manage and expand your BTQ CLI wallet using Slave keys.
