  • Key Outline of the Task assigned to the candidate (This includes Project name, Problem statement, expected Output and other relevant details) 



Implemented a fabric-sample and perform relevant transactions on it using CLI interface:

By running its test network and perform transactions as the functions are created in the SmartContract.go containing following functions:

  • InitLedger: This transaction initializes the ledger by adding a predefined set of base assets.
  • CreateAsset: It issues a new asset to the world state with the provided details.
  • ReadAsset: This transaction retrieves an asset from the world state based on the given asset ID.
  • UpdateAsset: It updates the details of an existing asset in the world state using the provided parameters.
  • DeleteAsset: This transaction removes a specified asset from the world state.
  • AssetExists: Checks whether an asset with a given ID exists in the world state and returns a boolean value.
  • TransferAsset: Updates the owner field of an asset with a given ID in the world state, returning the previous owner's information.
  • GetAllAssets: Retrieves all assets stored in the world state.


  • Chaincode on the network using the command:

./network.sh deployCC -ccn basic -ccp ../asset-transfer-basic/chaincode-go -ccl go

  • InitLedger: run the following command to call in InitLedger function 

peer chaincode invoke -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls --cafile "${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem" -C mychannel -n basic --peerAddresses localhost:7051 --tlsRootCertFiles "${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":"InitLedger","Args":[]}'

}


GetAllAssets:Retrieves all assets stored in the world state.

TransferAsset:Updates the owner field of an asset with a given ID in the world state
