+# Artifacts
+
 Artifacts that illustrate Earth Program use cases and solutions
+
+## Renewable Energy Certificates
+
+These artifacts help realize the Renewable Energy Certificates Focal Use Case.
+
+### Cryptographic Materials
+
+Many of the identifiers used in this set of artifacts are DIDs based on cryptographic public/private keypairs. This allows the artifacts' identifiers to be created offline and secured using cryptographic signatures.
+
+The public/private key pairs are Secp256k1 keys generated using [didkit](https://spruceid.dev/docs/didkit/) and represented in [Json Web Key](https://datatracker.ietf.org/doc/html/rfc7517) format. The .jwk files contain both the public and private keys for each actor. From these keys a DID and associated DID document has been generated using didkit.
+
+* **HydroElec** — The producer behind the proposed project.
+  * Key pair [./rec/keys/hydroelec.jwk](./rec/keys/hydroelec.jwk)
+  * DID document [./rec/dids/hydroelec.did.json](./rec/dids/hydroelec.did.json)
+
+* **Smart Meter 1** — The first of two electric meters that issue signed VCs as evidence of electricity production.
+  * Key pair [./rec/keys/meter1.jwk](./rec/keys/meter1.jwk)
+  * DID document [./rec/dids/meter1.did.json](./rec/dids/meter1.did.json)
+
+* **Smart Meter 2** — The second of two electric meters that issue signed VCs as evidence of electricity production.
+  * Key pair [./rec/keys/meter2.jwk](./rec/keys/meter2.jwk)
+  * DID document [./rec/dids/meter2.did.json](./rec/dids/meter2.did.json)
+
+* **UN FCCC** — The issuing authority for REC2022 Renewable Energy Certificates.
+  * Key pair [./rec/keys/unfccc.jwl](./rec/keys/unfccc.jwk)
+  * DID document [./rec/dids/unfccc.did.json](./rec/dids/unfccc.did.json)
+
+* **UN Rec2022** (DOES THIS NEED TO BE CRYPTOGRAPHIC?)
+  * Key pair [./rec/keys/un.rec2022.jwk](./rec/keys/un.rec2022.jwk)
+  * DID document [./rec/dids/un.rec2022.did.json](./rec/dids/un.rec2022.did.json)
+
+* **Certifier** — A UN authorized project certifier. They review the project proposal from the producer and issue an REC2022 Certification verifiable credential.
+  * Key pair [./rec/keys/certifier.jwk](./rec/keys/certifier.jwk)
+  * DID document [./rec/dids/certifier.did.json](./rec/dids/certifier.did.json)
+
+* **Verifier** — A UN authorized project verifier. They review the project on-site and issue an REC2022 Verification verifiable credential, based the propsoal, the REC2022 Certification, and the evidence produced by the Project's smart meters.
+  * Key pair [./rec/keys/verifier.jwk](./rec/keys/verifier.jwk)
+  * DID document [./rec/dids/verifier.did.json](./rec/dids/verifier.did.json)
+
+
+### Verifiable Credentials (VCs)
+
+1. Project Proposal
+
+This VC captures the automated metadata about the project and refers definitively for a descriptive PDF with additional details. [./rec/credentials/hydroelec.project1.json](./rec/credentials/hydroelec.project1.json)
+
+That file is a fully formed VC describing the following metadata:
+* **producer**: HydroElec's DID for exercising control over this project
+* **geographicLocation**: The GPS coordinates for the project location in Capetown, South Africa.
+* **dateProposed**: January 30, 2022
+* **annualTarget**: The expected annual electricity production of 1000 MWh
+
+It is signed by HydroElec. (Or, it will be. Currently the proof is faked.)
+
+2. Certifier Credential
+3. Verifier Credential
+4. Project Certification
+5. Project Verification
+6. Electricity Production
+
+### DIDs
+Throughout these examples, we use a fictional did:example which uses an Ed25519 public key for both the method-specific identifier and all of its verification methods.
+
+#### 1. HydroElec
+
+The file [./rec/keys/hydroelec.jwk](./rec/hydroelec.ed25519) is a representation of the private and public keys, respectively, that control this DID:
+
+```did:key:zQ3shPm1156YHd3pzvhz8BMtZPT9LnTxtGyFBnm8tzJmjnBWD```
+
+When this DID is resolved it returns the DID document found in [./rec/dids/hydroelec.did.json](./rec/dids/hydroelec.did.json)
+
+2. UNFCCC
+3. Certifier
+4. Verifier
+5. Project (as registered)
+
+### IIDs
+1. The NFT class created by the UNFCCC
+2. The particular NFT tokens minted
