# Nivix Hybrid Blockchain Setup
|
||||
|
||||
This document provides step-by-step instructions for setting up the Nivix hybrid blockchain architecture combining Solana and Hyperledger Fabric.
|
||||
|
||||
## Overview
|
||||
|
||||
The Nivix payment platform uses a hybrid architecture:
|
||||
- **Solana**: Handles fast and low-cost payment transactions
|
||||
- **Hyperledger Fabric**: Stores private KYC/AML data and transaction records
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Docker v28.1.1+
|
||||
- Docker Compose v2.35.1+
|
||||
- Go v1.20+
|
||||
- Hyperledger Fabric v2.5.12+
|
||||
|
||||
## Setup Instructions
|
||||
|
||||
### 1. Setting up the Hyperledger Fabric Test Network
|
||||
|
||||
```bash
|
||||
# Navigate to the test network directory
|
||||
cd /media/shubham/OS/for\ linux\ work/blockchain\ solana/hyperledger/fabric/fabric-samples/test-network
|
||||
|
||||
# Bring down any existing network
|
||||
./network.sh down
|
||||
|
||||
# Start a fresh Fabric network
|
||||
./network.sh up
|
||||
|
||||
# Create a channel named "mychannel"
|
||||
./network.sh createChannel
|
||||
```
|
||||
|
||||
### 2. Preparing the Nivix KYC Chaincode
|
||||
|
||||
```bash
|
||||
# Navigate to the chaincode directory
|
||||
cd /media/shubham/OS/for\ linux\ work/blockchain\ solana/hyperledger/fabric/fabric-samples/chaincode-nivix-kyc/go/nivix-kyc
|
||||
|
||||
# Add required dependencies
|
||||
go get github.com/hyperledger/fabric-contract-api-go/contractapi
|
||||
go mod tidy
|
||||
|
||||
# Prepare vendor directory
|
||||
go mod vendor
|
||||
```
|
||||
|
||||
### 3. Create Private Data Collections Configuration
|
||||
|
||||
Create a file named `collections_config.json` in the test-network directory:
|
||||
|
||||
```json
|
||||
[
|
||||
{
|
||||
"name": "kycCollection",
|
||||
"policy": "OR('Org1MSP.member', 'Org2MSP.member')",
|
||||
"requiredPeerCount": 0,
|
||||
"maxPeerCount": 1,
|
||||
"blockToLive": 1000000,
|
||||
"memberOnlyRead": true,
|
||||
"memberOnlyWrite": true,
|
||||
"endorsementPolicy": {
|
||||
"signaturePolicy": "OR('Org1MSP.member', 'Org2MSP.member')"
|
||||
}
|
||||
},
|
||||
{
|
||||
"name": "transactionCollection",
|
||||
"policy": "OR('Org1MSP.member', 'Org2MSP.member')",
|
||||
"requiredPeerCount": 0,
|
||||
"maxPeerCount": 1,
|
||||
"blockToLive": 1000000,
|
||||
"memberOnlyRead": true,
|
||||
"memberOnlyWrite": true,
|
||||
"endorsementPolicy": {
|
||||
"signaturePolicy": "OR('Org1MSP.member', 'Org2MSP.member')"
|
||||
}
|
||||
}
|
||||
]
|
||||
```
|
||||
|
||||
### 4. Deploy the Chaincode
|
||||
|
||||
```bash
|
||||
# Return to the test-network directory
|
||||
cd /media/shubham/OS/for\ linux\ work/blockchain\ solana/hyperledger/fabric/fabric-samples/test-network
|
||||
|
||||
# Install jq (required by scripts)
|
||||
sudo apt-get update && sudo apt-get install -y jq
|
||||
|
||||
# Deploy the chaincode
|
||||
./network.sh deployCC -ccn nivix-kyc -ccp ../chaincode-nivix-kyc/go/nivix-kyc -ccl go
|
||||
```
|
||||
|
||||
### 5. Update Chaincode with Private Collections
|
||||
|
||||
```bash
|
||||
# Set up environment variables for Org1
|
||||
export PATH=${PWD}/../bin:$PATH
|
||||
export FABRIC_CFG_PATH=$PWD/../config/
|
||||
export CORE_PEER_TLS_ENABLED=true

|
||||
export CORE_PEER_ADDRESS=localhost:9051
|
||||
|
||||

|
||||
```
|
||||
|
||||
## Testing the Chaincode
|
||||
|
||||
### 1. Store KYC Data
|
||||
|
||||
```bash
|
||||
# Store KYC data for user1
|
||||
peer chaincode invoke -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls --cafile "${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem" -C mychannel -n nivix-kyc --peerAddresses localhost:7051 --tlsRootCertFiles "${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt" --peerAddresses localhost:9051 --tlsRootCertFiles "${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt" -c '{"function":"StoreKYCData","Args":["user1", "Sol123456789", "John Doe", "true", "2025-05-17", "10", "a1b2c3d4e5f6"]}'
|
||||
|
||||
# Store KYC data for user2
|
||||
peer chaincode invoke -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls --cafile "${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem" -C mychannel -n nivix-kyc --peerAddresses localhost:7051 --tlsRootCertFiles "${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt" --peerAddresses localhost:9051 --tlsRootCertFiles "${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt" -c '{"function":"StoreKYCData","Args":["user2", "Sol987654321", "Jane Smith", "true", "2025-05-17", "5", "f6e5d4c3b2a1"]}'
|
||||
```
|
||||
|
||||
### 2. Query KYC Status
|
||||
|
||||
```bash
|
||||
# Query KYC status for user1
|
||||
peer chaincode query -C mychannel -n nivix-kyc -c '{"function":"GetKYCStatus","Args":["Sol123456789"]}'
|
||||
|
||||
# Query KYC status for user2
|
||||
peer chaincode query -C mychannel -n nivix-kyc -c '{"function":"GetKYCStatus","Args":["Sol987654321"]}'
|
||||
```
|
||||
|
||||
### 3. Record Solana Transaction
|
||||
|
||||
```bash
|
||||
# Record a transaction from Solana
|
||||
peer chaincode invoke -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls --cafile "${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem" -C mychannel -n nivix-kyc --peerAddresses localhost:7051 --tlsRootCertFiles "${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt" --peerAddresses localhost:9051 --tlsRootCertFiles "${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt" -c '{"function":"RecordTransaction","Args":["tx123", "solSig456", "user1", "user2", "100.5", "USDC", "2025-05-17T17:36:00Z"]}'
|
||||
```
|
||||
|
||||
## Understanding the Chaincode
|
||||
|
||||
The Nivix KYC chaincode provides the following functions:
|
||||
|
||||
1. `StoreKYCData`: Stores KYC information in a private data collection while maintaining a public reference of KYC status.
|
||||
|
||||
2. `GetKYCStatus`: Retrieves the public KYC status of a user by their Solana address without exposing personal information.
|
||||
|
||||
3. `RecordTransaction`: Records transaction data from Solana on the Hyperledger Fabric network for compliance and auditing purposes.
|
||||
|
||||
4. `GetTransactionSummary`: Retrieves a public summary of a transaction by its ID.
|
||||
|
||||
## Bringing Down the Network
|
||||
|
||||
When you're finished testing, you can bring down the network:
|
||||
|
||||
```bash
|
||||
./network.sh down
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
1. If you encounter chaincode installation errors, ensure that:
|
||||
- All required dependencies are installed
|
||||
- Go modules are properly set up
|
||||
- The chaincode path is correct
|
||||
|
||||
2. For issues with private collections:
|
||||
- Verify the collections configuration file is properly formatted
|
||||
- Check that `requiredPeerCount` is set to 0 if testing with minimal peers
|
||||
- Ensure the collection policy matches the channel members
|
||||
|
||||
3. If chaincode invocation fails:
|
||||
- Check that all parameters are correctly passed
|
||||
- Verify the function name matches exactly what's in the chaincode
|
||||
- Ensure the chaincode was successfully committed with collections config
