Gro Hunting

This guide is out of date. Since it was written, the ord binary was changed to only build the full gro index when the --index-sats flag is supplied. Additionally, ord now has a built-in wallet that wraps a Groestlcoin Core wallet. See ord wallet --help.

Ordinal hunting is difficult but rewarding. The feeling of owning a wallet full of UTXOs, redolent with the scent of rare and exotic gros, is beyond compare.

Ordinals are numbers for gros. Every gro has an ordinal number and every ordinal number has a gro.

Preparation

There are a few things you'll need before you start.

First, you'll need a synced Groestlcoin Core node with a transaction index. To turn on transaction indexing, pass -txindex on the command-line:
```
groestlcoind -txindex
```
Or put the following in your Groestlcoin configuration file:
```
txindex=1
```
Launch it and wait for it to catch up to the chain tip, at which point the following command should print out the current block height:
```
groestlcoin-cli getblockcount
```
Second, you'll need a synced ord index.
- Get a copy of ord from the repo.
- Run RUST_LOG=info ord index. It should connect to your groestlcoin core node and start indexing.
- Wait for it to finish indexing.
Third, you'll need a wallet with UTXOs that you want to search.

Searching for Rare Ordinals

Searching for Rare Ordinals in a Groestlcoin Core Wallet

The ord wallet command is just a wrapper around Groestlcoin Core's RPC API, so searching for rare ordinals in a Groestlcoin Core wallet is Easy. Assuming your wallet is named foo:

Load your wallet:
```
groestlcoin-cli loadwallet foo
```
Display any rare ordinals wallet foo's UTXOs:
```
ord wallet sats
```

Searching for Rare Ordinals in a Non-Groestlcoin Core Wallet

The ord wallet command is just a wrapper around Groestlcoin Core's RPC API, so to search for rare ordinals in a non-Groestlcoin Core wallet, you'll need to import your wallet's descriptors into Groestlcoin Core.

Descriptors describe the ways that wallets generate private keys and public keys.

You should only import descriptors into Groestlcoin Core for your wallet's public keys, not its private keys.

If your wallet's public key descriptor is compromised, an attacker will be able to see your wallet's addresses, but your funds will be safe.

If your wallet's private key descriptor is compromised, an attacker can drain your wallet of funds.

Get the wallet descriptor from the wallet whose UTXOs you want to search for rare ordinals. It will look something like this:

wpkh([bf1dd55e/84'/0'/0']xpub6CcJtWcvFQaMo39ANFi1MyXkEXM8T8ZhnxMtSjQAdPmVSTHYnc8Hwoc11VpuP8cb8JUTboZB5A7YYGDonYySij4XTawL6iNZvmZwdnSEEep/0/*)#csvefu29

Create a watch-only wallet named foo-watch-only:
```
groestlcoin-cli createwallet foo-watch-only true true
```
Feel free to give it a better name than foo-watch-only!

Load the foo-watch-only wallet:

groestlcoin-cli loadwallet foo-watch-only

Import your wallet descriptors into foo-watch-only:
```
groestlcoin-cli importdescriptors \
  '[{ "desc": "wpkh([bf1dd55e/84h/0h/0h]xpub6CcJtWcvFQaMo39ANFi1MyXkEXM8T8ZhnxMtSjQAdPmVSTHYnc8Hwoc11VpuP8cb8JUTboZB5A7YYGDonYySij4XTawL6iNZvmZwdnSEEep/0/*)#tpnxnxax", "timestamp":0 }]'
```
If you know the Unix timestamp when your wallet first started receive transactions, you may use it for the value of "timestamp" instead of 0. This will reduce the time it takes for Groestlcoin Core to search for your wallet's UTXOs.
Check that everything worked:
```
groestlcoin-cli getwalletinfo
```
Display your wallet's rare ordinals:
```
ord wallet sats
```

Searching for Rare Ordinals in a Wallet that Exports Multi-path Descriptors

Some descriptors describe multiple paths in one descriptor using angle brackets, e.g., <0;1>. Multi-path descriptors are not yet supported by Groestlcoin Core, so you'll first need to convert them into multiple descriptors, and then import those multiple descriptors into Groestlcoin Core.

First get the multi-path descriptor from your wallet. It will look something like this:

wpkh([bf1dd55e/84h/0h/0h]xpub6CcJtWcvFQaMo39ANFi1MyXkEXM8T8ZhnxMtSjQAdPmVSTHYnc8Hwoc11VpuP8cb8JUTboZB5A7YYGDonYySij4XTawL6iNZvmZwdnSEEep/<0;1>/*)#fw76ulgt

Create a descriptor for the receive address path:

wpkh([bf1dd55e/84'/0'/0']xpub6CcJtWcvFQaMo39ANFi1MyXkEXM8T8ZhnxMtSjQAdPmVSTHYnc8Hwoc11VpuP8cb8JUTboZB5A7YYGDonYySij4XTawL6iNZvmZwdnSEEep/0/*)

And the change address path:

wpkh([bf1dd55e/84'/0'/0']xpub6CcJtWcvFQaMo39ANFi1MyXkEXM8T8ZhnxMtSjQAdPmVSTHYnc8Hwoc11VpuP8cb8JUTboZB5A7YYGDonYySij4XTawL6iNZvmZwdnSEEep/1/*)

Get and note the checksum for the receive address descriptor, in this case tpnxnxax:

groestlcoin-cli getdescriptorinfo \
  'wpkh([bf1dd55e/84h/0h/0h]xpub6CcJtWcvFQaMo39ANFi1MyXkEXM8T8ZhnxMtSjQAdPmVSTHYnc8Hwoc11VpuP8cb8JUTboZB5A7YYGDonYySij4XTawL6iNZvmZwdnSEEep/0/*)'

{
  "descriptor": "wpkh([bf1dd55e/84'/0'/0']xpub6CcJtWcvFQaMo39ANFi1MyXkEXM8T8ZhnxMtSjQAdPmVSTHYnc8Hwoc11VpuP8cb8JUTboZB5A7YYGDonYySij4XTawL6iNZvmZwdnSEEep/0/*)#csvefu29",
  "checksum": "tpnxnxax",
  "isrange": true,
  "issolvable": true,
  "hasprivatekeys": false
}

And for the change address descriptor, in this case 64k8wnd7:

groestlcoin-cli getdescriptorinfo \
  'wpkh([bf1dd55e/84h/0h/0h]xpub6CcJtWcvFQaMo39ANFi1MyXkEXM8T8ZhnxMtSjQAdPmVSTHYnc8Hwoc11VpuP8cb8JUTboZB5A7YYGDonYySij4XTawL6iNZvmZwdnSEEep/1/*)'

{
  "descriptor": "wpkh([bf1dd55e/84'/0'/0']xpub6CcJtWcvFQaMo39ANFi1MyXkEXM8T8ZhnxMtSjQAdPmVSTHYnc8Hwoc11VpuP8cb8JUTboZB5A7YYGDonYySij4XTawL6iNZvmZwdnSEEep/1/*)#fyfc5f6a",
  "checksum": "64k8wnd7",
  "isrange": true,
  "issolvable": true,
  "hasprivatekeys": false
}

Load the wallet you want to import the descriptors into:
```
groestlcoin-cli loadwallet foo-watch-only
```

Now import the descriptors, with the correct checksums, into Groestlcoin Core.

groestlcoin-cli \
 importdescriptors \
 '[
   {
     "desc": "wpkh([bf1dd55e/84h/0h/0h]xpub6CcJtWcvFQaMo39ANFi1MyXkEXM8T8ZhnxMtSjQAdPmVSTHYnc8Hwoc11VpuP8cb8JUTboZB5A7YYGDonYySij4XTawL6iNZvmZwdnSEEep/0/*)#tpnxnxax"
     "timestamp":0
   },
   {
     "desc": "wpkh([bf1dd55e/84h/0h/0h]xpub6CcJtWcvFQaMo39ANFi1MyXkEXM8T8ZhnxMtSjQAdPmVSTHYnc8Hwoc11VpuP8cb8JUTboZB5A7YYGDonYySij4XTawL6iNZvmZwdnSEEep/1/*)#64k8wnd7",
     "timestamp":0
   }
 ]'

If you know the Unix timestamp when your wallet first started receive transactions, you may use it for the value of the "timestamp" fields instead of 0. This will reduce the time it takes for Groestlcoin Core to search for your wallet's UTXOs.

Check that everything worked:
```
groestlcoin-cli getwalletinfo
```
Display your wallet's rare ordinals:
```
ord wallet sats
```
