First Steps with Hedera Guardian {VERSION} and Digital Environmental Assets

The Hedera Guardian is an open source platform for issuing, verifying, and managing digital environmental assets. Follow the steps below to learn about primary capabilities of the Guardian.

Get set up 0/5

1

Create a Hedera testnet account

The Hedera Guardian operates on the Hedera network and a testnet or mainnet Hedera account is required.

Create a Hedera testnet account and add your details

  1. Visit the [Hedera Developer Portal](https://portal.hedera.com/login).

  2. Create a testnet account

  3. Note the Account ID (0.0.x) and the ED25519 DER Encoded Private Key (ignore ECDSA)

  4. Navigate to [Admin Settings](https://localhost/admin/settings)

  5. Copy the Account ID and ED25519 DER Encoded Private Key from the developer portal into the Operator ID and Operator Key fields

2

Import a policy

Policy's are digital workflows at the heart of the Hedera Guardian. The Guardian ecosystem hosts the worlds largest repository of open source digital environmental policies. Import a sample policy from the methodology library.

Import a policy from the methodology library

  1. Visit the [Methodology Library](https://github.com/hashgraph/guardian/tree/3.7.0/Methodology%20Library)

  2. Download the [Hello World Policy](https://github.com/hashgraph/guardian/blob/3.7.0/Methodology%20Library/Tutorials/HelloWorld.policy) policy file

  3. Navigate to [Manage Policies](https://localhost/manage/policies)

  4. Click the Import icon and select the HelloWorld.policy file

3

Publish a policy to testnet

When you publish a policy to testnet, policy users such as project proponents, auditors, or other defined stakeholders can interact with the policy by submitting, inspecting, or approving data.

Publish your first policy to the Hedera testnet

  1. Navigate to [Manage Policies | Open Link in new Tab]

  2. Click the dropdown in the status column and select publish.

  3. Set the Version to 1.0.0 and Availability to Public

  4. Click Publish

4

Send data to a policy (draft)

Visit your published Hello World policy and submit an estimated CO2e value to see how data flows through a policy workflow.

Send data to a policy

  1. Navigate to... and click the policy name to open it

  2. Select your role (e.g. Hello World Project Proponent)..

  3. Locate the CO2e Estimate form, choose from the activity drop down and enter a sample value.

  4. Click Submit

5

Inspect verifiable credentials documents (draft)

Every submission in Guardian generates a verifiable credential — a tamper-proof, cryptographically signed record of the claim you just submitted, which can be independently verified without trusting a central authority.

Inspect verifiable credential documents

  1. Navigate to Trust Chain or the Documents tab within your policy.

  2. Locate the entry corresponding to the CO2e estimate you submitted in Step 4

  3. Click the entry to open the raw VC document.

  4. Review the credentialSubject field to see your submitted claim data.

  5. Review the proof block to see the issuer's signature and signature type (e.g., Ed25519Signature2018).

  6. Note the associated Hedera Consensus Service timestamp to see when this credential's hash was recorded on the network.
