An Online Wallet System built-in Decentralized Identifiers in fulfillment of CS 199 by Antonio A. Aquino IV and Jack Vincent Nicolas
- Hyperledger Fabric Prerequisites
- Hyperledger Fabric Samples
- Aries Playground - Just clone the repository and create the docker network.
- TokenSDK
- Node.js
It is advisable to follow the order of installation based from the list above as it important to note that you should clone the OblePay github repository and then install the fabric-samples inside the OblePay repository
# To install the dependencies of the react app
npm install
# To start the Hyperledger Aries-Indy program, make sure to change the GENESIS_URL to http://greenlight.bcovrin.vonx.io/genesis in docker-compose.yml from the aries-playground repository and make sure to cd to aries-playground repository before running (Run this on another terminal):
docker-compose up
# Follow "Setting up Credentials System below before continuing
# To start the hyperledger fabric network, Token SDK and the react app. Make sure to cd to the Oble-Pay repository.
./startup.sh
# To issue tokens, use this cURL command from the Token SDK documentation
curl -X POST http://localhost:9100/api/v1/issuer/issue -H 'Content-Type: application/json' -d '{
"amount": {"code": "TOK","value": 1000},
"counterparty": {"node": "owner1","account": "alice"},
"message": "hello world!"
}'
# bring down fabric test network
./stop.sh
# Run Ctrl+C on the terminal running docker-compose up- Follow Create DID in a wallet from the link. Register the DiDs on the ledger.
- You will do this once times for localhost:8051, localhost:8052 and localhost:8053. However, you will only run
POST /wallet/did/publicon localhost:8051. - Send a schema to the ledger with the API
POST: /schemaswith the json body as given (this is done on localhost:8051 and take note of schema_id):
{
"schema_version": "1.0",
"schema_name": "UP Credentials",
"attributes": [
"upMail",
"name",
"studentNumber"
]
}
- Establish connection between the three agents by running these cURL commands.
# {CONNECTION BETWEEN ISSUER AND USER}
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# ISSUER (Create Inv)
issueInv=$(curl -X POST "http://localhost:8051/connections/create-invitation" -H "accept: application/json" | jq -r '.invitation')
# USER (Receive Inv)
issueCid=$(curl -X POST "http://localhost:8052/connections/receive-invitation" -H "accept: application/json" -H "Content-Type: application/json" -d "$issueInv" | jq -r '.connection_id')
# USER (Accept Inv)
curl -X POST "http://localhost:8052/connections/$issueCid/accept-invitation" -H "accept: application/json"
# {CONNECTION BETWEEN VERIFIER AND USER)
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# VERIFIER (Create Inv)
inv=$(curl -X POST "http://localhost:8053/connections/create-invitation" -H "accept: application/json" | jq -r '.invitation')
# USER (receive inv)
cid=$(curl -X POST "http://localhost:8052/connections/receive-invitation" -H "accept: application/json" -H "Content-Type: application/json" -d "$inv" | jq -r '.connection_id')
# USER (accept inv)
curl -X POST "http://localhost:8052/connections/$cid/accept-invitation" -H "accept: application/json"- Issuing of Credentials (On localhost:8051). Run
POST method /credential-definitionsusing the json body below (Take note of the cred_def_id).
{
"revocation_registry_size": 8,
"support_revocation": false,
"schema_id": "PLACE schema_id THAT YOU TOOK NOTE OF FROM INSTRUCTION 3.",
"tag": "default"
}
Then, Run POST /issue-credential/send using the json body below.
{
"schema_name": "UP Credentials",
"schema_version": "1.0",
"cred_def_id": "USE THE cred_def_id FROM /credential-definitions",
"auto_remove": false,
"comment": "string",
"connection_id": "GO TO CONNECTIONS AND LOOK FOR THE connection_id OF THE ACTIVE CONNECTION",
"trace": false,
"schema_issuer_did": "DERIVED FROM SCHEMA_ID, TAKE THE FIRST LETTERS UNTIL BEFORE THE FIRST :",
"schema_id": "USE THE SCHEMA_ID THAT WAS INITIALLY TAKEN NOTE OF",
"issuer_did": "SAME AS SCHEMA_ISSUER_DID",
"credential_proposal": {
"@type": "did:sov:BzCbsNYhMrjHiqZDTUASHg;spec/issue-credential/1.0/credential-preview",
"attributes": [
{
"name": "name",
"mime-type": "text/plain",
"value": "Alice"
},
{

},
{
"name": "studentNumber",
"mime-type": "text/plain",

}
]
}
}
- In the cloned Oble-Pay repository, go to test/my-app/src/pages/owner2.js
- Open localhost:8053 and run
GET /connectionsthen take note of the connection_id of the active connection. - Replace the
const [connectionId, setConnectionId] = useState('PLACE CONNECTION_ID HERE');and all of the cred_def_id value with what you took note of in instruction 5. - Finally, close the browser and go back to Quick Start.
