Verifiable Credentials RPCs
Note about Windows command escaping
This document will use Linux/MacOS RPC syntax. When running rpc commands on Windows, you'll need to escape all quotes with backslashes.
For example, here is a typical RPC command on Linux and MacOS:
chia rpc wallet vc_get '{"vc_id": "13ba084e78475327e41c60df5a108965d7a283f065b5506e266ffb3563937b6c"}'
To run the same command on Windows, you need to escape the quotes, so it looks like this (the braces have been removed to support the formatting for this page. You still need to use them in your actual commands.):
chia rpc wallet vc_get '\"vc_id\": \"13ba084e78475327e41c60df5a108965d7a283f065b5506e266ffb3563937b6c\"'

At this point, the credential has been transferred to the holder. In order for the holder to verify the VC, the holder will need to add the proofs manually to the local DB:
chia rpc wallet vc_add_proofs '{"proofs": {"example_proof_1": "example_value_1", "example_proof_2": "example_value_2"}}'
Response:
{

}
The holder can now view the VC and proofs:

vc_revoke
Functionality: Revoke an on chain VC provided the correct DID is available
Usage: chia rpc wallet [OPTIONS] vc_revoke [REQUEST]
Options:
| Short Command | Long Command | Type | Required | Description |
|---|---|---|---|---|
| -j | --json-file | TEXT | False | Instead of REQUEST, provide a json file containing the request data |
| -h | --help | None | False | Show a help message and exit |
Request Parameters:
| Parameter | Type | Required | Description |
|---|---|---|---|
| vc_parent_id | STRING | True | The parent ID of the VC coin |
| reuse_puzhash | None | False | If this flag is set, then send the VC back to the same puzzle hash it came from [Default: generate new puzzle hash] |
| fee | INTEGER | False | An optional blockchain fee, in mojos |
Example
First, the proof provider can obtain the VC's parent_coin_info by calling vc_get on the launcher ID:
chia rpc wallet vc_get '{"vc_id": "0xd2097d50519925faa13b224257a4e5ddca4f5234230fc5b1606552325a2d3a4e"}'

}
}
}
}
Next, the proof provider can revoke the VC, passing in the parent_coin_info obtained above as the vc_parent_id:
chia rpc wallet vc_revoke '{"vc_parent_id": "0x1b4136963ef41ece657772ef70ca9d23b03c42a16ecb8f57748d7fdc90e0987b", "fee": 100000000}'

Obtain proof hash
In order to obtain a proof hash:
- Sort the proofs into reverse alphabetical order by key
- Transform the proofs' key/value pairs into a binary tree by recursively splitting the list in half
- Recursively traverse the tree, hashing the leaves until the root is reached
The following example accomplishes each of these steps in Javascript:
Javascript Example
In order to run this example:
- Copy the script to a text editor
- Replace the keys and values in the last line with the keys and values from your own proof(s)
- Save the script locally, for example, as
calculate_proof_hash.js - Run the script by calling, for example,
node calculate_proof_hash.js
const { strict: assert } = require('node:assert');
const crypto = require('crypto');
const std_hash = (s) => crypto.createHash('sha256').update(s).digest('hex');
const sort_pairs = (pairs) =>
pairs.sort(([a], [b]) => {
if (a < b) {
return 1;
}
if (a > b) {
return -1;
}
return 0;
});
const CHIA_TREE_HASH_ATOM_PREFIX = '01';
const CHIA_TREE_HASH_PAIR_PREFIX = '02';
const tree_hash = (node) => {
if (Array.isArray(node)) {
// Only supporting pairs and utf-8 string/boolean atoms
assert.equal(node.length, 2);
const left_hash = tree_hash(node[0]);
const right_hash = tree_hash(node[1]);
// Hashes pair
return std_hash(
Buffer.concat([
Buffer.from(CHIA_TREE_HASH_PAIR_PREFIX, 'hex'),
Buffer.from(left_hash, 'hex'),
Buffer.from(right_hash, 'hex'),
]),
);
} else {
// Hashes string key
if (typeof node === 'string') {
return std_hash(
Buffer.concat([
Buffer.from(CHIA_TREE_HASH_ATOM_PREFIX, 'hex'),
Buffer.from(node, 'utf-8'),
]),
);
}
// Hashes boolean value
if (typeof node === 'boolean') {
return std_hash(
Buffer.concat([
Buffer.from(CHIA_TREE_HASH_ATOM_PREFIX, 'hex'),
Buffer.from(node ? '01' : '', 'hex'),
]),
);
}
// Only supporting pairs containing string keys and boolean values
throw new Error('Unsupported type passed to hash function');
}
};
// Convert sorted listed to binary tree to be hashed
const list_to_binary_tree = (objects) => {
if (objects.length == 1) {
return objects[0];
}
const mid = Math.floor(objects.length / 2);
const first_half = objects.slice(0, mid);
const second_half = objects.slice(mid, objects.length);
return [list_to_binary_tree(first_half), list_to_binary_tree(second_half)];
};
const calculate_root_hash = (proofs) => {
const kv_pairs = Object.entries(proofs);
const sorted = sort_pairs(kv_pairs);
const binary_tree = list_to_binary_tree(sorted);
const result = tree_hash(binary_tree);
return result;
};
console.log(
calculate_root_hash({
example_proof_1: 'example_value_1',
example_proof_2: 'example_value_2',
}),
);
The script will output the proof hash for the proofs your entered. In this example, the output is:
