# Asset-Transfer-Basic as an external service # Asset-Transfer-Basic as an external service
See the "Chaincode as an external service" documentation for an introduction on how to run chaincode as an external service. This sample provides an introduction to how to use external builder and launcher scripts to run chaincode as an external service to your peer. For more information, see the [Chaincode as an external service](https://hyperledger-fabric.readthedocs.io/en/latest/cc_launcher.html) topic in the Fabric documentation.
This sample includes the external builder and launcher scripts which the peers in your Fabric network will require
in order to run an asset transfer chaincode as an external service.
**Note:** each organization in a real network would need to setup and host their own instance of the external service. For simplification purpose, in this sample we use the same instance for both organizations. **Note:** each organization in a real network would need to setup and host their own instance of the external service.

# Private data asset transfer scenario [Using Private Data tutorial](https://hyperledger-fabric.readthedocs.io/en/latest/private_data_tutorial.html)
The private data asset transfer smart contract uses a simple asset transfer to demonstrate the use of private data collections. All the data that is created by the smart contract is stored in the private data that are collections specified in the `collections_config.json` file:
- The `assetCollection` is deployed on the peers of Org1 and Org2. This collection is used to store the main asset details, such as the size, color, and owner. The `"memberOnlyRead"` and `"memberOnlyWrite"` parameters are used to specify that only Org1 and Org2 can read and write to this collection.
- The `Org1MSPPrivateCollection` is deployed only on the Org1 peer. Similarly, the `Org2MSPPrivateCollection` is only deployed on the Org2 peer. These organization specific collections are used to store the appraisal value of the asset. This allows the owner of the asset to keep the value of the asset private from other organizations on the channel. The `"endorsementPolicy"` parameter is used to create a collection specific endorsement policy. Each update to `Org1MSPPrivateCollection` or `Org2MSPPrivateCollection` needs to be endorsed by the organization that stores the collection on their peers.
These three collections are used to transfer the asset between Org1 and Org2. In the tutorial, you will use the private data smart contract to complete the following transfer scenario:
- A member of Org1 uses the `CreateAsset` function to create a new asset. The `CreateAsset` function reads the certificate information of the client identity that submitted the transaction using the `GetClientIdentity.GetID()` API and creates a new asset with the client identity as the asset owner. The main details of the asset, including the owner, are stored in the `assetCollection` collection. The asset is also created with an appraised value. The appraised value is used by each participant to agree to the transfer of the asset, and is only stored in each organization specific collection. Because the asset is created by a member of Org1, the initial appraisal value agreed by the asset owner is stored in the `Org1MSPPrivateCollection`.
- A member of Org2 creates an agreement to trade using the `AgreeToTransfer` function. The potential buyer uses this function to agree to an appraisal value. The value is stored in `Org2MSPPrivateCollection`, and can only read by a member of Org2. The `AgreeToTransfer` function also uses the `GetClientIdentity().GetID()` API to read the client identity that is agreeing to the Transfer. The **TransferAgreement** is stored in the `assetCollection` as a key with the name "transferAgreement{assetID}"
- After the member of Org2 has agreed to the transfer, the asset owner can transfer the asset to the buyer using the `TransferAsset` function. The smart contract completes a couple of checks before the asset is transferred:
- The transfer request is submitted by the owner of the asset.
- The smart contract uses the `GetPrivateDataHash()` function to check that the hash of the asset appraisal value in `Org1MSPPrivateCollection` matches the hash of the appraisal value in the `Org2MSPPrivateCollection`. If the hashes are the same, it confirms that the owner and the interested buyer have agreed to the same asset value.
If both conditions are met, the transfer function will get the client ID of the buyer from the transfer agreement and make the buyer the new owner of the asset. The transfer function will also delete the asset appraisal value from the collection of the former owner, as well as remove the transfer agreement from the `assetCollection`.
The private data asset transfer enabled by this smart contract is meant to demonstrate the use private data collections. For an example of a more realistic transfer scenario, see the [secure asset transfer smart contract](../../asset-transfer-secured-agreement/chaincode-go).
## Deploy the smart contract to the test network
You can run the private data transfer scenario using the Fabric test network. Open a command terminal and navigate to test network directory in your local clone of the `fabric-samples`. We will operate from the `test-network` directory for the remainder of the tutorial.
```
cd fabric-samples/test-network
```
Run the following command to deploy the test network:
```
./network.sh up createChannel -ca -s couchdb
```
The test network is deployed with two peer organizations. The `createChannel` flag deploys the network with a single channel named `mychannel` with Org1 and Org2 as channel members. The `-ca` flag is used to deploy the network using certificate authorities. This allows you to use each organization's CA to register and enroll new users for this tutorial.
## Deploy the smart contract to the channel
You can use the test network script to deploy the private data smart contract to the channel that was just created. Deploy the smart contract to `mychannel` using the following command:
```
./network.sh deployCC -ccn private -ccep "OR('Org1MSP.peer','Org2MSP.peer')" -cccg ../asset-transfer-private-data/chaincode-go/collections_config.json
```
The above command deploys the go chaincode with short name `private`, and specifies the private data collection configuration from file `collections_config.json` using `-cccg` flag.
Note that we are using the `-ccep` flag to deploy the private data smart contract with a chaincode endorsement policy of `"OR('Org1MSP.peer','Org2MSP.peer')"`. This allows Org1 and Org2 to create an asset without receiving an endorsement from the other organization.
Now you are ready to call the deployed smart contract.
Note that this sample workflow steps below, can also be executed via the application at `asset-transfer-private-data/application-javascript` folder, in fewer steps. To execute the workflow via CLI, read on.
## Register identities
The private data transfer smart contract supports ownership by individual identities that belong to the network. In our scenario, the owner of the asset will be a member of Org1, while the buyer will belong to Org2. To highlight the connection between the `GetClientIdentity().GetID()` API and the information within a user's certificate, we will register two new identities using the Org1 and Org2 Certificate Authorities (CA's), and then use the CA's to generate each identity's certificate and private key.
First, we need to set the following environment variables to use the the Fabric CA client:
```
export PATH=${PWD}/../bin:${PWD}:$PATH
export FABRIC_CFG_PATH=$PWD/../config/
```
We will use the Org1 CA to create the identity asset owner. Set the Fabric CA client home to the MSP of the Org1 CA admin (this identity was generated by the test network script):
```
export FABRIC_CA_CLIENT_HOME=${PWD}/organizations/peerOrganizations/org1.example.com/
```
You can register a new owner client identity using the `fabric-ca-client` tool:
```
fabric-ca-client register --caname ca-org1 --id.name owner --id.secret ownerpw --id.type client --tls.certfiles ${PWD}/organizations/fabric-ca/org1/tls-cert.pem
```
You can now generate the identity certificates and MSP folder by providing the enroll name and secret to the enroll command:
```
fabric-ca-client enroll -u https://owner:ownerpw@localhost:7054 --caname ca-org1 -M ${PWD}/organizations/peerOrganizations/org1.example.com/users/owner@org1.example.com/msp --tls.certfiles ${PWD}/organizations/fabric-ca/org1/tls-cert.pem
```
Run the command below to copy the Node OU configuration file into the owner identity MSP folder.
```
cp ${PWD}/organizations/peerOrganizations/org1.example.com/msp/config.yaml ${PWD}/organizations/peerOrganizations/org1.example.com/users/owner@org1.example.com/msp/config.yaml
```
We can now use the Org2 CA to create the buyer identity. Set the Fabric CA client home the Org2 CA admin:
```
export FABRIC_CA_CLIENT_HOME=${PWD}/organizations/peerOrganizations/org2.example.com/
```
You can register a new owner client identity using the `fabric-ca-client` tool:
```
fabric-ca-client register --caname ca-org2 --id.name buyer --id.secret buyerpw --id.type client --tls.certfiles ${PWD}/organizations/fabric-ca/org2/tls-cert.pem
```
We can now enroll to generate the identity MSP folder:
```
fabric-ca-client enroll -u https://buyer:buyerpw@localhost:8054 --caname ca-org2 -M ${PWD}/organizations/peerOrganizations/org2.example.com/users/buyer@org2.example.com/msp --tls.certfiles ${PWD}/organizations/fabric-ca/org2/tls-cert.pem
```
Run the command below to copy the Node OU configuration file into the buyer identity MSP folder.
```
cp ${PWD}/organizations/peerOrganizations/org2.example.com/msp/config.yaml ${PWD}/organizations/peerOrganizations/org2.example.com/users/buyer@org2.example.com/msp/config.yaml
```
## Create an asset
Now that we have created the identity of the asset owner, we can invoke the private data smart contract to create a new asset. Use the following environment variables to operate the `peer` CLI as the owner identity from Org1.
```
export CORE_PEER_TLS_ENABLED=true
export CORE_PEER_LOCALMSPID="Org1MSP"
export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.example.com/users/owner@org1.example.com/msp
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt
export CORE_PEER_ADDRESS=localhost:7051
```
Run the following command to define the asset properties:
```
export ASSET_PROPERTIES=$(echo -n "{\"objectType\":\"asset\",\"assetID\":\"asset1\",\"color\":\"green\",\"size\":20,\"appraisedValue\":100}" | base64 | tr -d \\n)
```
We can then invoke the smart contract to create the new asset:
```
peer chaincode invoke -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n private -c '{"function":"CreateAsset","Args":[]}' --transient "{\"asset_properties\":\"$ASSET_PROPERTIES\"}"
```
The command above uses the transient data flag, `--transient`, to provide the asset details to the smart contract. Transient data is not part of the transaction read/write set, and as result is not stored on the channel ledger.
Note that command above only targets the Org1 peer. The `CreateAsset` transactions writes to two collections, `assetCollection` and `Org1MSPPrivateCollection`. The `Org1MSPPrivateCollection` requires and endorsement from the Org1 peer in order to write to the collection, while the `assetCollection` inherits the endorsement policy of the chaincode, `"OR('Org1MSP.peer','Org2MSP.peer')"`. An endorsement from the Org1 peer can meet both endorsement policies and is able to create an asset without an endorsement from Org2.
We can read the main details of the asset that was created by using the `ReadAsset` function to query the `assetCollection` collection:
```
peer chaincode query -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 private -c '{"function":"ReadAsset","Args":["asset1"]}'
```
When successful, the command will return the following result:
```
{"objectType":"asset","assetID":"asset1","color":"green","size":20,"owner":"eDUwOTo6Q049b3duZXIsT1U9Y2xpZW50LE89SHlwZXJsZWRnZXIsU1Q9Tm9ydGggQ2Fyb2xpbmEsQz1VUzo6Q049Y2Eub3JnMS5leGFtcGxlLmNvbSxPPW9yZzEuZXhhbXBsZS5jb20sTD1EdXJoYW0sU1Q9Tm9ydGggQ2Fyb2xpbmEsQz1VUw=="}
```
The `"owner"` of the asset is the identity that created the asset by invoking the smart contract. The `GetClientIdentity().GetID()` API reads the common name and issuer of the identity certificate. You can see that information by decoding the owner string out of base64 format:
```
echo eDUwOTo6Q049b3duZXIsT1U9Y2xpZW50LE89SHlwZXJsZWRnZXIsU1Q9Tm9ydGggQ2Fyb2xpbmEsQz1VUzo6Q049Y2Eub3JnMS5leGFtcGxlLmNvbSxPPW9yZzEuZXhhbXBsZS5jb20sTD1EdXJoYW0sU1Q9Tm9ydGggQ2Fyb2xpbmEsQz1VUw | base64 --decode
```
The result will show the common name and issuer of the owner certificate:
```
x509::CN=owner,OU=client,O=Hyperledger,ST=North Carolina,C=US::CN=ca.org1.example.com,O=org1.example.com,L=Durham,ST=North Carolina,C=Umacbook-air:test-network
```
A member of Org1 can also read the private asset appraisal value that is stored in the `Org1MSPPrivateCollection` on the Org1 peer:
```
peer chaincode query -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n private -c '{"function":"ReadAssetPrivateDetails","Args":["Org1MSPPrivateCollection","asset1"]}'
```
The query will return the value of the asset:
```
{"assetID":"asset1","appraisedValue":100}
```
### Buyer from Org2 agrees to buy the asset
The buyer identity from Org2 is interested in buying the asset. In a new terminal, set the following environment variables to operate as the buyer:
```
export CORE_PEER_LOCALMSPID="Org2MSP"
export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org2.example.com/users/buyer@org2.example.com/msp
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt
export CORE_PEER_ADDRESS=localhost:9051
```
Now that we are operating as a member of Org2, we can demonstrate that the asset appraisal is not stored in Org2MSPPrivateCollection, on the Org2 peer:
```
peer chaincode query -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 private -c '{"function":"ReadAssetPrivateDetails","Args":["Org2MSPPrivateCollection","asset1"]}'
```
The empty response shows that, the asset1 private details, does not exist in buyer private collection.
Nor can a member of Org2, able to read the Org1 private data collection:
```
peer chaincode query -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n private -c '{"function":"ReadAssetPrivateDetails","Args":["Org1MSPPrivateCollection","asset1"]}'
```
By setting `"memberOnlyRead": true` in the collection configuration file, we specify that only members of Org1 can read data from the collection. A Org2 member who tries to read the collection would only get the following response.
```
Error: endorsement failure during query. response: status:500 message:"failed to read from asset details GET_STATE failed: transaction ID: 10d39a7d0b340455a19ca4198146702d68d884d41a0e60936f1599c1ddb9c99d: tx creator does not have read access permission on privatedata in chaincodeName:private collectionName: Org1MSPPrivateCollection"
```
To purchase the asset, the buyer needs to agree to the same value as the asset owner. The agreed value will be stored in the `Org2MSPDetailsCollection` collection on the Org2 peer. Run the following command to agree to the appraised value of 100:
```
export ASSET_VALUE=$(echo -n "{\"assetID\":\"asset1\",\"appraisedValue\":100}" | base64 | tr -d \\n)
peer chaincode invoke -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n private -c '{"function":"AgreeToTransfer","Args":[]}' --transient "{\"asset_value\":\"$ASSET_VALUE\"}"
```
The buyer can now query the value they agreed to in the Org2 private data collection:
```
peer chaincode query -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n private -c '{"function":"ReadAssetPrivateDetails","Args":["Org2MSPPrivateCollection","asset1"]}'
```
The invoke will return the following value:
```
{"assetID":"asset1","appraisedValue":100}
```
## Org1 member transfers the asset to Org2
Now that buyer has agreed to buy the asset for appraised value, the owner from Org1 can transfer the asset to Org2. In the first terminal (with the following environment variables to operate as Org1):
```
export CORE_PEER_LOCALMSPID="Org1MSP"
export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.example.com/users/owner@org1.example.com/msp
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt
export CORE_PEER_ADDRESS=localhost:7051
```
Now that buyer has agreed to buy the asset for appraised value, the owner from Org1 can read the data added by `AgreeToTransfer` to see buyer identity.
```
peer chaincode query -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n private -c '{"function":"ReadTransferAgreement","Args":["asset1"]}'
```
The owner from Org1 can now transfer the asset to Org2. To transfer the asset, the owner needs to pass the MSP ID of new asset owner Org. The transfer function will read the client ID of the interested buyer user from the transfer agreement.
```
export ASSET_OWNER=$(echo -n "{\"assetID\":\"asset1\",\"buyerMSP\":\"Org2MSP\"}" | base64 | tr -d \\n)
```
The owner of the asset needs to initiate the transfer.
```
peer chaincode invoke -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n private -c '{"function":"TransferAsset","Args":[]}' --transient "{\"asset_owner\":\"$ASSET_OWNER\"}" --peerAddresses localhost:7051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt
```
You can ReadAsset `asset1` to see the results of the transfer.
```
peer chaincode query -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 private -c '{"function":"ReadAsset","Args":["asset1"]}'
```
The results will show that the buyer identity now owns the asset:
```
{"objectType":"asset","assetID":"asset1","color":"green","size":20,"owner":"eDUwOTo6Q049YnV5ZXIsT1U9Y2xpZW50LE89SHlwZXJsZWRnZXIsU1Q9Tm9ydGggQ2Fyb2xpbmEsQz1VUzo6Q049Y2Eub3JnMi5leGFtcGxlLmNvbSxPPW9yZzIuZXhhbXBsZS5jb20sTD1IdXJzbGV5LFNUPUhhbXBzaGlyZSxDPVVL"}
```
You can base64 decode the `"owner"` to see that it is the buyer identity:
```
x509::CN=buyer,OU=client,O=Hyperledger,ST=North Carolina,C=US::CN=ca.org2.example.com,O=org2.example.com,L=Hursley,ST=Hampshire,C=UKmacbook-air
```
You can also confirm that transfer removed the private details from the Org1 collection:

```
Your query will return empty result, since the asset private data is removed from the Org1 private data collection.
## Clean up
When you are finished, you can bring down the test network. The command will remove all the nodes of the test network, and delete any ledger data that you created:
```
./network.sh down
```

## Simple blind auction sample
The simple blind auction sample uses Hyperledger Fabric to run an auction where bids are kept private until the auction period is over. Instead of displaying the full bid on the public ledger, buyers can only see hashes of other bids while bidding is underway. This prevents buyers from changing their bids in response to bids submitted by others. After the bidding period ends, participants reveal their bid to try to win the auction. The organizations participating in the auction verify that a revealed bid matches the hash on the public ledger. Whichever has the highest bid wins.
A user that wants to sell one item can use the smart contract to create an auction. The auction is stored on the channel ledger and can be read by all channel members. The auctions created by the smart contract are run in three steps:
1. Each auction is created with the status **open**. While the auction is open, buyers can add new bids to the auction. The full bids of each buyer are stored in the implicit private data collections of their organization. After the bid is created, the bidder can submit the hash of the bid to the auction. A bid is added to the auction in two steps because the transaction that creates the bid only needs to be endorsed by a peer of the bidders organization, while a transaction that updates the auction may need to be endorsed by multiple organizations. When the bid is added to the auction, the bidder's organization is added to the list of organizations that need to endorse any updates to the auction.
2. The auction is **closed** to prevent additional bids from being added to the auction. After the auction is closed, bidders that submitted bids to the auction can reveal their full bid. Only revealed bids can win the auction.
3. The auction is **ended** to calculate the winner from the set of revealed bids. All organizations participating in the auction calculate the price that clears the auction and the winning bid. The seller can end the auction only if all bidding organizations endorse the same winner and price.
Before endorsing the transaction that ends the auction, each organization queries the implicit private data collection on their peers to check if any organization member has a winning bid that has not yet been revealed. If a winning bid is found, the organization will withhold their endorsement and prevent the auction from being closed. This prevents the seller from ending the auction prematurely, or colluding with buyers to end the auction at an artificially low price.
The sample uses several Fabric features to make the auction private and secure. Bids are stored in private data collections to prevent bids from being distributed to other peers in the channel. When bidding is closed, the auction smart contract uses the `GetPrivateDataHash()` API to verify that the bid stored in private data is the same bid that is being revealed. State based endorsement is used to add the organization of each bidder to the auction endorsement policy. The smart contract uses the `GetClientIdentity.GetID()` API to ensure that only the potential buyer can read their bid from private state and only the seller can close or end the auction.
This tutorial uses the auction smart contract in a scenario where one seller wants to auction a painting. Four potential buyers from two different organizations will submit bids to the auction and try to win the auction.
## Deploy the chaincode
We will run the auction smart contract using the Fabric test network. Open a command terminal and navigate to the test network directory:
```
cd fabric-samples/test-network
```
You can then run the following command to deploy the test network.
```
./network.sh up createChannel -ca
```
Note that we use the `-ca` flag to deploy the network using certificate authorities. We will use the CA to register and enroll our sellers and buyers.
Run the following command to deploy the auction smart contract. We will override the default endorsement policy to allow any channel member to create an auction without requiring an endorsement from another organization.
```
./network.sh deployCC -ccn auction -ccp ../auction/chaincode-go/ -ccep "OR('Org1MSP.peer','Org2MSP.peer')"
```
## Install the application dependencies
We will interact with the auction smart contract through a set of Node.js applications. Change into the `application-javascript` directory:
```
cd fabric-samples/auction/application-javascript
```
From this directory, run the following command to download the application dependencies:
```
npm install
```
## Register and enroll the application identities
To interact with the network, you will need to enroll the Certificate Authority administrators of Org1 and Org2. You can use the `enrollAdmin.js` program for this task. Run the following command to enroll the Org1 admin:
```
node enrollAdmin.js org1
```
You should see the logs of the admin wallet being created on your local file system. Now run the command to enroll the CA admin of Org2:
```
node enrollAdmin.js org2
```
We can use the CA admins of both organizations to register and enroll the identities of the seller that will create the auction and the bidders who will try to purchase the painting.
Run the following command to register and enroll the seller identity that will create the auction. The seller will belong to Org1.
```
node registerEnrollUser.js org1 seller
```
You should see the logs of the seller wallet being created as well. Run the following commands to register and enroll 2 bidders from Org1 and another 2 bidders from Org2:
```
node registerEnrollUser.js org1 bidder1
node registerEnrollUser.js org1 bidder2
node registerEnrollUser.js org2 bidder3
node registerEnrollUser.js org2 bidder4
```
## Create the auction
The seller from Org1 would like to create an auction to sell a vintage Matchbox painting. Run the following command to use the seller wallet to run the `createAuction.js` application. The program will submit a transaction to the network that creates the auction on the channel ledger. The organization and identity name are passed to the application to use the wallet that was created by the `registerEnrollUser.js` application. The seller needs to provide an ID for the auction and the item to be sold to create the auction:
```
node createAuction.js org1 seller PaintingAuction painting
```
After the transaction is complete, the `createAuction.js` application will query the auction stored in the public channel ledger:
```
*** Result: Auction: {
"objectType": "auction",
"item": "painting",
"seller": "eDUwOTo6Q049c2VsbGVyLE9VPWNsaWVudCtPVT1vcmcxK09VPWRlcGFydG1lbnQxOjpDTj1jYS5vcmcxLmV4YW1wbGUuY29tLE89b3JnMS5leGFtcGxlLmNvbSxMPUR1cmhhbSxTVD1Ob3J0aCBDYXJvbGluYSxDPVVT",
"organizations": [
"Org1MSP"
],
"privateBids": {},
"revealedBids": {},
"winner": "",
"price": 0,
"status": "open"
}
```
The smart contract uses the `GetClientIdentity().GetID()` API to read identity that creates the auction and defines that identity as the auction `"seller"`. You can see the seller information by decoding the `"seller"` string out of base64 format:
```
echo eDUwOTo6Q049c2VsbGVyLE9VPWNsaWVudCtPVT1vcmcxK09VPWRlcGFydG1lbnQxOjpDTj1jYS5vcmcxLmV4YW1wbGUuY29tLE89b3JnMS5leGFtcGxlLmNvbSxMPUR1cmhhbSxTVD1Ob3J0aCBDYXJvbGluYSxDPVVT | base64 --decode
```
The result is the name and issuer of the seller's certificate:
```
x509::CN=org1admin,OU=admin,O=Hyperledger,ST=North Carolina,C=US::CN=ca.org1.example.com,O=org1.example.com,L=Durham,ST=North Carolina,C=USn
```
## Bid on the auction
We can now use the bidder wallets to submit bids to the auction:
### Bid as bidder1
Bidder1 will create a bid to purchase the painting for 800 dollars.
```
node bid.js org1 bidder1 PaintingAuction 800
```
The application will query the bid after it is created:
```
*** Result: Bid: {
"objectType": "bid",
"price": 800,
"org": "Org1MSP",
"bidder": "eDUwOTo6Q049YmlkZGVyMSxPVT1jbGllbnQrT1U9b3JnMStPVT1kZXBhcnRtZW50MTo6Q049Y2Eub3JnMS5leGFtcGxlLmNvbSxPPW9yZzEuZXhhbXBsZS5jb20sTD1EdXJoYW0sU1Q9Tm9ydGggQ2Fyb2xpbmEsQz1VUw=="
}
```
The bid is stored in the Org1 implicit data collection. The `"bidder"` parameter is the information from the certificate of the user that created the bid. Only this identity will be able can query the bid from private state or reveal the bid during the auction.
The `bid.js` application also prints the bidID:
```
*** Result ***SAVE THIS VALUE*** BidID: 8ef83011a5fb791f75ed008337839426f6b87981519e5d58ef5ada39c3044edd
```
The BidID acts as the unique identifier for the bid. This ID allows you to query the bid using the `queryBid.js` program and add the bid to the auction. Save the bidID returned by the application as an environment variable in your terminal:
```
export BIDDER1_BID_ID=8ef83011a5fb791f75ed008337839426f6b87981519e5d58ef5ada39c3044edd
```
This value will be different for each transaction, so you will need to use the value returned in your terminal.
Now that the bid has been created, you can submit the bid to the auction. Run the following command to submit the bid that was just created:
```
node submitBid.js org1 bidder1 PaintingAuction $BIDDER1_BID_ID
```
The hash of bid will be added to the list private bids in that have been submitted to `PaintingAuction`. Storing the hash in the public auction allows users to accurately reveal the bid after bidding is closed. The application will query the auction to verify that the bid was added:
```
*** Result: Auction: {
"objectType": "auction",
"item": "painting",
"seller": "eDUwOTo6Q049c2VsbGVyLE9VPWNsaWVudCtPVT1vcmcxK09VPWRlcGFydG1lbnQxOjpDTj1jYS5vcmcxLmV4YW1wbGUuY29tLE89b3JnMS5leGFtcGxlLmNvbSxMPUR1cmhhbSxTVD1Ob3J0aCBDYXJvbGluYSxDPVVT",

}
},
"revealedBids": {},
"winner": "",
"price": 0,

}
```
### Bid as bidder2
Let's submit another bid. Bidder2 would like to purchase the painting for 500 dollars.
```
node bid.js org1 bidder2 PaintingAuction 500
```
Save the Bid ID returned by the application:
```
export BIDDER2_BID_ID=915a908c8f2c368f4a3aedd73176656af81ddfab000b11629503403f3d97b185
```
Submit bidder2's bid to the auction:
```
node submitBid.js org1 bidder2 PaintingAuction $BIDDER2_BID_ID
```
### Bid as bidder3 from Org2
Bidder3 will bid 700 dollars for the painting:
```
node bid.js org2 bidder3 PaintingAuction 700
```
Save the Bid ID returned by the application:
```
export BIDDER3_BID_ID=5e4e637c68833b178739575f6fe09820b019551a8cfbb43a4d172e0aa864dfad
```
Add bidder3's bid to the auction:
```
node submitBid.js org2 bidder3 PaintingAuction $BIDDER3_BID_ID
```
Because bidder3 belongs to Org2, submitting the bid will add Org2 to the list of participating organizations. You can see the Org2 MSP ID has been added to the list of `"organizations"` in the updated auction returned by the application:
```
*** Result: Auction: {
"objectType": "auction",
"item": "painting",
"seller": "eDUwOTo6Q049c2VsbGVyLE9VPWNsaWVudCtPVT1vcmcxK09VPWRlcGFydG1lbnQxOjpDTj1jYS5vcmcxLmV4YW1wbGUuY29tLE89b3JnMS5leGFtcGxlLmNvbSxMPUR1cmhhbSxTVD1Ob3J0aCBDYXJvbGluYSxDPVVT",

}
},
"revealedBids": {},
"winner": "",
"price": 0,

}
```
Now that a bid from Org2 has been added to the auction, any updates to the auction need to be endorsed by the Org2 peer. The applications will use `"organizations"` field to specify which organizations need to endorse submitting a new bid, revealing a bid, or updating the auction status.
### Bid as bidder4
Bidder4 from Org2 would like to purchase the painting for 900 dollars:
```
node bid.js org2 bidder4 PaintingAuction 900
```
Save the Bid ID returned by the application:
```
export BIDDER4_BID_ID=49466271ae879bd009e75a60730a12bfa986e75f263202ab81ccd3deec544a35
```
Add bidder4's bid to the auction:
```
node submitBid.js org2 bidder4 PaintingAuction $BIDDER4_BID_ID
```
## Close the auction
Now that all four bidders have joined the auction, the seller would like to close the auction and allow buyers to reveal their bids. The seller identity that created the auction needs to submit the transaction:
```
node closeAuction.js org1 seller PaintingAuction
```
The application will query the auction to allow you to verify that the auction status has changed to closed. As a test, you can try to create and submit a new bid to verify that no new bids can be added to the auction.
## Reveal bids
After the auction is closed, bidders can try to win the auction by revealing their bids. The transaction to reveal a bid needs to pass four checks:
1. The auction is closed.
2. The transaction was submitted by the identity that created the bid.
3. The hash of the revealed bid matches the hash of the bid on the channel ledger. This confirms that the bid is the same as the bid that is stored in the private data collection.
4. The hash of the revealed bid matches the hash that was submitted to the auction. This confirms that the bid was not altered after the auction was closed.
Use the `revealBid.js` application to reveal the bid of Bidder1:
```
node revealBid.js org1 bidder1 PaintingAuction $BIDDER1_BID_ID
```

Bidder3 from Org2 will also reveal their bid:
```
node revealBid.js org2 bidder3 PaintingAuction $BIDDER3_BID_ID
```
If the auction ended now, Bidder1 would win. Let's try to end the auction using the seller identity and see what happens.
```
node endAuction.js org1 seller PaintingAuction
```
The output should look something like the following:
```
--> Submit the transaction to end the auction
2020-11-06T13:16:11.591Z - warn: [TransactionEventHandler]: strategyFail: commit failure for transaction "99feade5b7ec223839200867b57d18971c3e9f923efc95aaeec720727f927366": TransactionError: Commit of transaction 99feade5b7ec223839200867b57d18971c3e9f923efc95aaeec720727f927366 failed on peer peer0.org1.example.com:7051 with status ENDORSEMENT_POLICY_FAILURE

```
Instead of ending the auction, the transaction results in an endorsement policy failure. The end of the auction needs to be endorsed by Org2. Before endorsing the transaction, the Org2 peer queries its private data collection for any winning bids that have not yet been revealed. Because Bidder4 created a bid that is above the winning price, the Org2 peer refuses to endorse the transaction that would end the auction.
Before we can end the auction, we need to reveal the bid from bidder4.
```
node revealBid.js org2 bidder4 PaintingAuction $BIDDER4_BID_ID
```
Bidder2 from Org1 would not win the auction in either case. As a result, Bidder2 decides not to reveal their bid.
## End the auction
Now that the winning bids have been revealed, we can end the auction:
```
node endAuction org1 seller PaintingAuction
```
The transaction was successfully endorsed by both Org1 and Org2, who both calculated the same price and winner. The winning bidder is listed along with the price:
```

## Clean up
When your are done using the auction smart contract, you can bring down the network and clean up the environment. In the `auction/application-javascript` directory, run the following command to remove the wallets used to run the applications:
```
rm -rf wallet
```
You can then navigate to the test network directory and bring down the network:
````
cd ../../test-network/
./network.sh down
````

### Vendor the chaincode dependencies
1. Change into the chaincode directory, e.g. `cd ~/fabric-samples/high-throughput/chaincode`
2. Vendor the Go dependencies by running the following command: `GO111MODULE=on go mod vendor`
3. The chaincode directory will now contain a `vendor` directory.

You can use the `startFabric.sh` script to create an instance of the Fabric test network with a single channel named `mychannel`. The script then deploys the `high-throughput` chaincode to the channel by installing it on the test network peers and committing the chaincode definition to the channel.

All invocations are provided as scripts in `scripts` folder. You can use these scripts to create and remove assets that you put on the ledger.
You can invoke the `high-througput` chaincode using a Go application in the `application-go` folder. The Go application will allow us to submit many transactions to the network concurrently. Navigate to the application:

### Test the Network ### Test the Network
Two scripts are provided to show the advantage of using this system when running many parallel transactions at once: `many-updates.sh` and
`many-updates-traditional.sh`. The first script accepts the same arguments as `update-invoke.sh` but duplicates the invocation 1000 times
and in parallel. The final value, therefore, should be the given update value * 1000. Run this script to confirm that your network is functioning
properly. You can confirm this by checking your peer and orderer logs and verifying that no invocations are rejected due to improper versions.
The second script, `many-updates-traditional.sh`, also sends 1000 transactions but using the traditional storage system. It'll update a single The application provides two methods that demonstrate the advantages of this system by submitting many concurrent transactions to the smart contract: `manyUpdates` and `manyUpdatesTraditional`. The first function accepts the same arguments as `update-invoke.sh` but runs the invocation 1000 times in parallel. The final value, therefore, should be the given update value * 1000.
row in the ledger 1000 times, with a value incrementing by one each time (i.e. the first invocation sets it to 0 and the last to 1000). The
expectation would be that the final value of the row is 999. However, the final value changes each time this script is run and you'll find
errors in the peer and orderer logs.
There are two other scripts, `get-traditional.sh`, which simply gets the value of a row in the traditional way, with no deltas, and `del-traditional.sh` will delete an asset in the traditional way. The second function, `manyUpdatesTraditional`, submits 1000 transactions that attempt to upddate the same key in the world state 1000 times.
Examples: Run the following command to create and update `testvar1` a 1000 times:
`./scripts/many-updates.sh testvar 100 +` --> final value from `./scripts/get-invoke.sh testvar` should be 100000 ```
go run app.go manyUpdates testvar1 100 +
```
`./scripts/many-updates-traditional.sh testvar` --> final value from `./scripts/get-traditional.sh testvar` is undefined The application will query the variable after submitting the transaction. The result should be `100000`.
We will now see what happens when you try to run 1000 concurrent updates using a traditional transaction. Run the following command to create a variable named `testvar2`:
```
go run app.go update testvar2 100 +
```
The variable will have a value of 100:
```
2020/10/27 18:01:45 Value of variable testvar2 : 100
```
Now lets try to update `testvar2` 1000 times in parallel:
```
go run app.go manyUpdatesTraditional testvar2 100 +
```
When the program ends, you may see that none of the updates succeeded.
```
2020/10/27 18:03:15 Final value of variable testvar2 : 100
```
The transactions failed because multiple transactions in each block updated the same key. Because of these transactions generated read/write conflicts, the transactions included in each block were rejected in the validation stage.
You can can examine the peer logs to view the messages generated by the rejected blocks:
