# Asset transfer secured agreement sample
|
||||||
|
|
||||||
|
The asset transfer events sample demonstrates how to transfer a private asset between two organizations without publicly sharing data .
|
||||||
|
|
||||||
|
## About the sample
|
||||||
|
|
||||||
|
This sample includes smart contract and application code in multiple languages. This sample shows how Fabric features state based endorsement, private data, and access control to provide secured transactions.
|
||||||
|
|
||||||
|
### Application
|
||||||
|
|
||||||
|
Refer [Secured asset transfer in Fabric](https://hyperledger-fabric.readthedocs.io/en/latest/secured_asset_transfer/secured_private_asset_transfer_tutorial.html) for application details .
|
||||||
|
|
||||||
|
### Smart Contract
|
||||||
|
|
||||||
|
The smart contract (in folder `chaincode-go`) implements the following functions to support the application:
|
||||||
|
|
||||||
|
- CreateAsset
|
||||||
|
- ChangePublicDescription
|
||||||
|
- AgreeToSell
|
||||||
|
- AgreeToBuy
|
||||||
|
- VerifyAssetProperties
|
||||||
|
- TransferAsset
|
||||||
|
- ReadAsset
|
||||||
|
- GetAssetPrivateProperties
|
||||||
|
- GetAssetSalesPrice
|
||||||
|
- GetAssetBidPrice
|
||||||
|
- QueryAssetSaleAgreements
|
||||||
|
- QueryAssetBuyAgreements
|
||||||
|
- QueryAssetHistory
|
||||||
|
|
||||||
|
## Running the sample
|
||||||
|
|
||||||
|
Like other samples, the Fabric test network is used to deploy and run this sample. Follow these steps in order:
|
||||||
|
|
||||||
|
1. Create the test network and a channel (from the `test-network` folder).
|
||||||
|
```
|
||||||
|
./network.sh up createChannel -c mychannel -ca
|
||||||
|
```
|
||||||
|
|
||||||
|
1. Deploy the smart contract implementations.
|
||||||
|
```
|
||||||
|
# To deploy the go chaincode implementation
|
||||||
|
./network.sh deployCC -ccn secured -ccp ../asset-transfer-secured-agreement/chaincode-go/ -ccl go -ccep "OR('Org1MSP.peer','Org2MSP.peer')"
|
||||||
|
```
|
||||||
|
|
||||||
|
1. Run the application (from the `asset-transfer-secured-agreement` folder).
|
||||||
|
```
|
||||||
|
# To run the Typescript sample application
|
||||||
|
cd application-gateway-typescript
|
||||||
|
npm install
|
||||||
|
npm start
|
||||||
|
|
||||||
|
# To run the Javascript sample application
|
||||||
|
cd application-javascript
|
||||||
|
node app.js
|
||||||
|
```
|
||||||
|
|
||||||
|
## Clean up
|
||||||
|
|
||||||
|
When you are finished, you can bring down the test network (from the `test-network` folder). The command will remove all the nodes of the test network, and delete any ledger data that you created.
|
||||||
|
|
||||||
|
```
|
||||||
|
./network.sh down
|
||||||
|
```
