-# Gradle start up script for POSIX generated by Gradle.
-#
-# Important for running:
-#
-# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
-# noncompliant, but you have some other compliant shell such as ksh or
-# bash, then to run this script, type that shell name before the whole
-# command line, like:
-#
-# ksh Gradle
-#
-# Busybox and similar reduced shells will NOT work, because this script
-# requires all of these POSIX shell features:
-# * functions;
-# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
-# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
-# * compound commands having a testable exit status, especially «case»;
-# * various built-in commands including «command», «set», and «ulimit».
-#
-# Important for patching:
-#
-# (2) This script targets any POSIX shell, so it avoids extensions provided
-# by Bash, Ksh, etc; in particular arrays are avoided.
-#
-# The "traditional" practice of packing multiple parameters into a
-# space-separated string is a well documented source of bugs and security
-# problems, so this is (mostly) avoided, by progressively accumulating
-# options in "$@", and eventually passing that to Java.
-#
-# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
-# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
-# see the in-line comments for details.
-#
-# There are tweaks for specific operating systems such as AIX, CygWin,
-# Darwin, MinGW, and NonStop.
-#
-# (3) This script is generated from the Groovy template
-# https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
-# within the Gradle project.

-INDEXES TO SUPPORT COUCHDB RICH QUERIES
-
-Indexes in CouchDB are required in order to make JSON queries efficient and are required for
-any JSON query with a sort. Indexes may be packaged alongside
-chaincode in a META-INF/statedb/couchdb/indexes directory. Each index must be defined in its own
-text file with extension *.json with the index definition formatted in JSON following the
-CouchDB index JSON syntax as documented at:
-http://docs.couchdb.org/en/2.3.1/api/database/find.html#db-index
-
-This asset transfer ledger example chaincode demonstrates a packaged
-index which you can find in META-INF/statedb/couchdb/indexes/indexOwner.json.
-
-If you have access to the your peer's CouchDB state database in a development environment,
-you may want to iteratively test various indexes in support of your chaincode queries. You
-can use the CouchDB Fauxton interface or a command line curl utility to create and update
-indexes. Then once you finalize an index, include the index definition alongside your
-chaincode in the META-INF/statedb/couchdb/indexes directory, for packaging and deployment
-to managed environments.
-
-In the examples below you can find index definitions that support asset transfer ledger
-chaincode queries, along with the syntax that you can use in development environments
-to create the indexes in the CouchDB Fauxton interface or a curl command line utility.
-
-
-Index for docType, owner.
-
-Example curl command line to define index in the CouchDB channel_chaincode database
-curl -i -X POST -H "Content-Type: application/json" -d "{\"index\":{\"fields\":[\"docType\",\"owner\"]},\"name\":\"indexOwner\",\"ddoc\":\"indexOwnerDoc\",\"type\":\"json\"}" http://hostname:port/myc1_assets/_index
-
-
-Index for docType, owner, size (descending order).
-
-Example curl command line to define index in the CouchDB channel_chaincode database:
-curl -i -X POST -H "Content-Type: application/json" -d "{\"index\":{\"fields\":[{\"size\":\"desc\"},{\"docType\":\"desc\"},{\"owner\":\"desc\"}]},\"ddoc\":\"indexSizeSortDoc\", \"name\":\"indexSizeSortDesc\",\"type\":\"json\"}" http://hostname:port/myc1_assets/_index
-
-Rich Query with index design doc and index name specified (Only supported if CouchDB is used as state database):
-peer chaincode query -C myc1 -n asset_transfer -c '{"Args":["QueryAssets","{\"selector\":{\"docType\":\"asset\",\"owner\":\"tom\"}, \"use_index\":[\"_design/indexOwnerDoc\", \"indexOwner\"]}"]}'
-
-Rich Query with index design doc specified only (Only supported if CouchDB is used as state database):
-peer chaincode query -C myc1 -n asset_transfer -c '{"Args":["QueryAssets","{\"selector\":{\"docType\":{\"$eq\":\"asset\"},\"owner\":{\"$eq\":\"tom\"},\"size\":{\"$gt\":0}},\"fields\":[\"docType\",\"owner\",\"size\"],\"sort\":[{\"size\":\"desc\"}],\"use_index\":\"_design/indexSizeSortDoc\"}"]}'

-// http://docs.couchdb.org/en/2.3.1/api/database/find.html#db-index
-//
-// This asset transfer ledger example chaincode demonstrates a packaged
-// index which you can find in META-INF/statedb/couchdb/indexes/indexOwner.json.
-//
-// If you have access to the your peer's CouchDB state database in a development environment,
-// you may want to iteratively test various indexes in support of your chaincode queries. You
-// can use the CouchDB Fauxton interface or a command line curl utility to create and update
-// indexes. Then once you finalize an index, include the index definition alongside your
-// chaincode in the META-INF/statedb/couchdb/indexes directory, for packaging and deployment
-// to managed environments.
-//
-// In the examples below you can find index definitions that support asset transfer ledger
-// chaincode queries, along with the syntax that you can use in development environments
-// to create the indexes in the CouchDB Fauxton interface or a curl command line utility.
-//
-
-// Index for docType, owner.
-//
-// Example curl command line to define index in the CouchDB channel_chaincode database
-// curl -i -X POST -H "Content-Type: application/json" -d "{\"index\":{\"fields\":[\"docType\",\"owner\"]},\"name\":\"indexOwner\",\"ddoc\":\"indexOwnerDoc\",\"type\":\"json\"}" http://hostname:port/myc1_assets/_index
-//
-
-// Index for docType, owner, size (descending order).
-//
-// Example curl command line to define index in the CouchDB channel_chaincode database
-// curl -i -X POST -H "Content-Type: application/json" -d "{\"index\":{\"fields\":[{\"size\":\"desc\"},{\"docType\":\"desc\"},{\"owner\":\"desc\"}]},\"ddoc\":\"indexSizeSortDoc\", \"name\":\"indexSizeSortDesc\",\"type\":\"json\"}" http://hostname:port/myc1_assets/_index
-
-// Rich Query with index design doc and index name specified (Only supported if CouchDB is used as state database):
-// peer chaincode query -C CHANNEL_NAME -n ledger -c '{"Args":["QueryAssets","{\"selector\":{\"docType\":\"asset\",\"owner\":\"Tom\"}, \"use_index\":[\"_design/indexOwnerDoc\", \"indexOwner\"]}"]}'
-
-// Rich Query with index design doc specified only (Only supported if CouchDB is used as state database):
-// peer chaincode query -C CHANNEL_NAME -n ledger -c '{"Args":["QueryAssets","{\"selector\":{\"docType\":{\"$eq\":\"asset\"},\"owner\":{\"$eq\":\"Tom\"},\"size\":{\"$gt\":0}},\"fields\":[\"docType\",\"owner\",\"size\"],\"sort\":[{\"size\":\"desc\"}],\"use_index\":\"_design/indexSizeSortDoc\"}"]}'

-# Asset transfer private data sample
-
-The asset transfer private data sample demonstrates:
-
-- Usage of organization private data collections
-- Read data from the organization private data collection.
-- Store data in organization private data collection.
-
-For more information about private data, visit the
-[Private Data](https://hyperledger-fabric.readthedocs.io/en/latest/private-data-arch.html)
-page in the Fabric documentation.
-
-## About the sample
-
-This sample includes smart contract and application code in multiple languages. In a use-case similar to basic asset transfer (see [asset-transfer-basic](../asset-transfer-basic) folder) this sample shows sending and receiving of asset along with its private data owned by organizations during create / delete of an asset , and during transfer of an asset to a new owner.
-
-### Application
-
-Please refer the below link to understand the application flow.
-https://hyperledger-fabric.readthedocs.io/en/latest/private-data/private-data.html#example-scenario-asset-transfer-using-private-data-collections
-
-### Smart Contract
-
-The smart contract (in folder `chaincode-xyz`) implements the following functions to support the application:
-
-CreateAsset
-AgreeToTransfer
-TransferAsset
-DeleteAsset
-DeleteTranferAgreement
-
-ReadAsset
-ReadAssetPrivateDetails
-ReadTransferAgreement
-GetAssetByRange
-QueryAssetByOwner
-QueryAssets
-getQueryResultForQueryString
-
-## 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
- ```
-
-2. Deploy one of the smart contract implementations (from the `test-network` folder).
- ```
- # To deploy the Java chaincode implementation
- ./network.sh deployCC -ccn private -ccp ../asset-transfer-private-data/chaincode-java -ccl java -ccep "OR('Org1MSP.peer','Org2MSP.peer')" -cccg '../asset-transfer-private-data/chaincode-java/collections_config.json' -ccep "OR('Org1MSP.peer','Org2MSP.peer')"
-
- # To deploy the go chaincode implementation
- ./network.sh deployCC -ccn private -ccp ../asset-transfer-private-data/chaincode-go -ccl go -ccep "OR('Org1MSP.peer','Org2MSP.peer')" -cccg '../asset-transfer-private-data/chaincode-go/collections_config.json' -ccep "OR('Org1MSP.peer','Org2MSP.peer')"
-
- # To deploy the typescript chaincode implementation
- ./network.sh deployCC -ccn private -ccp ../asset-transfer-private-data/chaincode-typescript/ -ccl typescript -ccep "OR('Org1MSP.peer','Org2MSP.peer')" -cccg ../asset-transfer-private-data/chaincode-typescript/collections_config.json
- ```
-
-3. Run the application (from the `asset-transfer-private-data` folder).
- ```
- # To run the Typescript sample application
- cd application-gateway-typescript
- npm install
- npm start
-
- # To run the Go sample application
- cd application-gateway-go
- go run .
- ```
-
-## 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
-```

-# Asset Transfer Private Data Sample
-
-This app uses fabric-samples/test-network based setup and the companion chaincode asset-transfer-private-data/chaincode-go/ with chaincode endorsement policy as "OR('Org1MSP.peer','Org2MSP.peer')"
-
-For this usecase illustration, we will use both Org1 & Org2 client identity from this same app
-In real world the Org1 & Org2 identity will be used in different apps to achieve asset transfer.
-
-For more details refer:
-https://hyperledger-fabric.readthedocs.io/en/release-2.4/private_data_tutorial.html#pd-use-case

-// =======Rich queries =========================================================================
-// Two examples of rich queries are provided below (parameterized query and ad hoc query).
-// Rich queries pass a query string to the state database.
-// Rich queries are only supported by state database implementations
-// that support rich query (e.g. CouchDB).
-// The query string is in the syntax of the underlying state database.
-// With rich queries there is no guarantee that the result set hasn't changed between
-// endorsement time and commit time, aka 'phantom reads'.
-// Therefore, rich queries should not be used in update transactions, unless the
-// application handles the possibility of result set changes between endorsement and commit time.
-// Rich queries can be used for point-in-time queries against a peer.
-// ============================================================================================

-// QueryAssetByOwner queries for assets based on assetType, owner.

-# Gradle start up script for POSIX generated by Gradle.
-#
-# Important for running:
-#
-# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
-# noncompliant, but you have some other compliant shell such as ksh or
-# bash, then to run this script, type that shell name before the whole
-# command line, like:
-#
-# ksh Gradle
-#
-# Busybox and similar reduced shells will NOT work, because this script
-# requires all of these POSIX shell features:
-# * functions;
-# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
-# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
-# * compound commands having a testable exit status, especially «case»;
-# * various built-in commands including «command», «set», and «ulimit».
-#
-# Important for patching:
-#
-# (2) This script targets any POSIX shell, so it avoids extensions provided
-# by Bash, Ksh, etc; in particular arrays are avoided.
-#
-# The "traditional" practice of packing multiple parameters into a
-# space-separated string is a well documented source of bugs and security
-# problems, so this is (mostly) avoided, by progressively accumulating
-# options in "$@", and eventually passing that to Java.
-#
-# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
-# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
-# see the in-line comments for details.
-#
-# There are tweaks for specific operating systems such as AIX, CygWin,
-# Darwin, MinGW, and NonStop.
-#
-# (3) This script is generated from the Groovy template
-# https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
-# within the Gradle project.
-#
-# You can find Gradle at https://github.com/gradle/gradle/.

-# State-based endorsement asset transfer sample
-
-Transactions that are submitted to Hyperledger Fabric networks need to be endorsed
-by peers that are joined to a channel before the transaction can be added to the
-ledger. Fabric peers endorse transactions by executing a smart contract using the
-inputs of the transaction proposal. The peers then sign the input and output
-generated by the smart contract execution. The endorsement policy specifies the
-set of organizations whose peers need to endorse a transaction before it can be
-added to the ledger.
-
-Each chaincode that is deployed to a channel has an endorsement policy that governs
-the assets managed by the chaincode smart contracts. However, you can override the
-chaincode level endorsement policy to create an endorsement policy for a specific key,
-either on the public channel ledger or in a private collection.
-State-based endorsement policies, also known as key-level endorsement policies, allow
-channel members to use different endorsement policies for assets that are managed by
-the same smart contract. For more information about endorsement policies and
-state-based endorsement, visit the
-[Endorsement Policies](https://hyperledger-fabric.readthedocs.io/en/release-2.2/endorsement-policies.html)
-topic in the Fabric documentation.
-
-The implementation provided by State Based interface creates a policy which requires signatures from all the Org principals added, and hence is equivalent to an AND policy. For other advanced State Based policy implementations which are not supported by State Based interface directly like OR or NOutOf policies, please refer to method implementations setStateBasedEndorsementNOutOf(), which can be used as an alternative for setStateBasedEndorsement() inside asset-transfer-sbe smart contracts.
-
-## About the Sample
-
-The state-based endorsement (SBE) asset transfer sample demonstrates how to use
-key-level endorsement policies to ensure that an asset only is endorsed by an
-asset owner. In the course of the tutorial, you will use the smart contract
-to complete the following transfer scenario:
-
-- Deploy the SBE smart contract to a channel that was created using the Fabric
-test network. The channel will have two members, Org1 and Org2, that will
-participate in the asset transfer. Each organization operates one peer that
-is joined to the channel.
-- Create an asset using the chaincode endorsement policy. The chaincode level
-endorsement policy requires that a majority of organizations on the channel
-endorse a transaction. This means that a transaction that creates an asset
-needs to be endorsed by peers that belong to Org1 and Org2. When the asset is
-created, the smart contract creates a state-based endorsement policy that
-specifies that only the organization that owns that asset may endorse update
-transactions. Because the asset is owned by Org1, any future updates to the asset
-need to be endorsed by the Org1 peer.
-- Update the asset by only endorsing with Org1, this will use the state-based
-endorsement policy applied to the asset when it was created by the chaincode.
-- Transfer the asset to Org2. During the execution of the transfer transaction,
-the chaincode will create a new state-based endorsement policy that reflects
-the new asset owner for the asset.
-- Update the asset once more, this time with Org2 as the owner. Because the
-state-based endorsement policy has been updated, this transaction only needs
-to be endorsed by Org2.
-
-## Deploy the smart contract
-
-We are going to run the SBE smart contract 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 and create a channel named `mychannel`:
-
-```
-./network.sh up createChannel
-```
-
-You can use the test network script to deploy the smart contract to the channel that was just created. The script uses the Fabric chaincode lifecycle to deploy the smart contract to the channel. We will use the default chaincode level endorsement policy used by the Fabric chaincode lifecycle, which requires an endorsement from a majority of channel members. In our case, this will require that both Org1 and Org2 endorse a transaction (2 of 2). Deploy the smart contract to `mychannel` using the following command:
-```
-./network.sh deployCC -ccn sbe -ccp ../asset-transfer-sbe/chaincode-typescript/ -ccl typescript
-```
-
-Set the following environment variables to interact with the network as a user from Org1:
-
-```
-export PATH=${PWD}/../bin:${PWD}:$PATH
-export FABRIC_CFG_PATH=$PWD/../config/
-export CORE_PEER_TLS_ENABLED=true
-export CORE_PEER_LOCALMSPID=Org1MSP
-export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.example.com/users/User1@org1.example.com/msp
-export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt
-export CORE_PEER_ADDRESS=localhost:7051
-```
-
-## Run the transfer scenario
-
-We can now invoke the SBE smart contract to create a new asset:
-```
-peer chaincode invoke -o localhost:7050 --waitForEvent --ordererTLSHostnameOverride orderer.example.com --tls --cafile "${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem" -C mychannel -n sbe --peerAddresses localhost:7051 --tlsRootCertFiles "${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt" --peerAddresses localhost:9051 --tlsRootCertFiles "${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt" -c '{"function":"CreateAsset","Args":["asset1","100","Org1User1"]}'
-```
-The create transaction needs to target both peers from Org1 and Org2 to meet the chaincode endorsement policy. The chaincode will read the MSP ID of the client user submitting the transaction and assign that organization as the asset owner. As a result, the asset will initially be owned by Org1.
-
-You can query the asset using with the following command:
-```
-peer chaincode query -C mychannel -n sbe -c '{"Args":["ReadAsset","asset1"]}'
-```
-The result is a new asset owned by Org1, identified using the Org1 MSP ID `Org1MSP`:
-`{"ID":"asset1","Value":100,"Owner":"Org1User1","OwnerOrg":"Org1MSP"}`
-
-In addition to creating the asset, the `CreateAsset` function also sets a state-based endorsement policy for the asset. Only a peer of the asset owner, can successfully endorse an asset update. To demonstrate the key-level endorsement policy, lets try to update the asset while targeting the Org2 peer:
-```
-peer chaincode invoke -o localhost:7050 --waitForEvent --ordererTLSHostnameOverride orderer.example.com --tls --cafile "${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem" -C mychannel -n sbe --peerAddresses localhost:9051 --tlsRootCertFiles "${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt" -c '{"function":"UpdateAsset","Args":["asset1","200"]}'
-```
-The result is an endorsement policy failure:
-```
-Error: transaction invalidated with status (ENDORSEMENT_POLICY_FAILURE) - proposal response:
-```
-
-If we attempt to update the asset with an endorsement from the Org1 peer, the update succeeds:
-```
-peer chaincode invoke -o localhost:7050 --waitForEvent --ordererTLSHostnameOverride orderer.example.com --tls --cafile "${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem" -C mychannel -n sbe --peerAddresses localhost:7051 --tlsRootCertFiles "${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt" -c '{"function":"UpdateAsset","Args":["asset1","200"]}'
-```
-You can query the asset one more time to verify that the update was successful:
-```
-peer chaincode query -C mychannel -n sbe -c '{"Args":["ReadAsset","asset1"]}'
-```
-
-The asset value is now 200:
-```
-{"ID":"asset1","Value":200,"Owner":"Org1User1","OwnerOrg":"Org1MSP"}
-```
-
-Now that we have tested the asset key-level endorsement policy, we can transfer the asset to Org2. Run the following command to transfer the asset from Org1 to Org2. This time the Org2 MSP ID is provided as a transaction input. The `TransferAsset` function will update the endorsement policy to specify that only a peer of the new owner can update the asset. Note that this command targets the Org1 peer.
-
-```
-peer chaincode invoke -o localhost:7050 --waitForEvent --ordererTLSHostnameOverride orderer.example.com --tls --cafile "${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem" -C mychannel -n sbe --peerAddresses localhost:7051 --tlsRootCertFiles "${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt" -c '{"function":"TransferAsset","Args":["asset1","Org2User1","Org2MSP"]}'
-```
-
-We can query the asset to see that the owner has been updated from Org1 to Org2:
-```
-peer chaincode query -C mychannel -n sbe -c '{"Args":["ReadAsset","asset1"]}'
-```
-
-The owning organization is now Org2:
-```
-{"ID":"asset1","Value":200,"Owner":"Org2User1","OwnerOrg":"Org2MSP"}
-```
-
-Org2 now needs to endorse any asset updates. Run the following command to try to update the asset with an endorsement from the Org1 peer:
-```
-peer chaincode invoke -o localhost:7050 --waitForEvent --ordererTLSHostnameOverride orderer.example.com --tls --cafile "${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem" -C mychannel -n sbe --peerAddresses localhost:7051 --tlsRootCertFiles "${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt" -c '{"function":"UpdateAsset","Args":["asset1","300"]}'
-```
-
-The response will be an endorsement policy failure:
-```
-Error: transaction invalidated with status (ENDORSEMENT_POLICY_FAILURE) - proposal response:
-```
-
-Now try to update the asset with an endorsement from the Org2 peer:
-```
-peer chaincode invoke -o localhost:7050 --waitForEvent --ordererTLSHostnameOverride orderer.example.com --tls --cafile "${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem" -C mychannel -n sbe --peerAddresses localhost:9051 --tlsRootCertFiles "${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt" -c '{"function":"UpdateAsset","Args":["asset1","300"]}'
-```
-
-You can query the asset again to verify that the transaction update succeeded:
-```
-peer chaincode query -C mychannel -n sbe -c '{"Args":["ReadAsset","asset1"]}'
-```
-
-The asset value is now 300:
-```
-{"ID":"asset1","Value":300,"Owner":"Org2User1","OwnerOrg":"Org2MSP"}
-```
-
-Note that the transaction to update the asset was submitted by a user from Org1, even though the asset was owned by Org2. The transfer enabled by the SBE smart contract is a simple scenario meant only to demonstrate the use of state-based endorsement policies. The smart contract can use access control to specify that an asset can only be updated by its owner. Private data collections can also be used to ensure that transfers need to be endorsed by the owner and recipient of the transfer, instead of just the asset owner. For a more realistic example of an asset transfer scenario, see the [Secured asset transfer in Fabric](https://hyperledger-fabric.readthedocs.io/en/master/secured_asset_transfer/secured_private_asset_transfer_tutorial.html) tutorial.
-
-## 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
-```

-// - fabric-sample two organization test-network setup with two peers, ordering service,
-// and 2 certificate authorities
-// ===> from directory /fabric-samples/test-network
-// ./network.sh up createChannel -ca
-// - Use any of the asset-transfer-sbe chaincodes deployed on the channel "mychannel"
-// with the chaincode name of "sbe". The following deploy command will package,
-// install, approve, and commit the javascript chaincode, all the actions it takes
-// to deploy a chaincode to a channel.
-// ===> from directory /fabric-samples/test-network
-// ./network.sh deployCC -ccn sbe -ccp ../asset-transfer-sbe/chaincode-typescript/ -ccl typescript
-// - Be sure that node.js is installed
-// ===> from directory /fabric-samples/asset-transfer-sbe/application-javascript
-// node -v
-// - npm installed code dependencies
-// ===> from directory /fabric-samples/asset-transfer-sbe/application-javascript
-// npm install
-// - to run this test application
-// ===> from directory /fabric-samples/asset-transfer-sbe/application-javascript
-// node app.js

- Error in setup: Error: DiscoveryService: mychannel error: access denied
-
- OR
-
- Failed to register user : Error: fabric-ca request register failed with errors [[ { code: 20, message: 'Authentication failure' } ]]
-
- */
-// Delete the /fabric-samples/asset-transfer-sbe/application-javascript/wallet directory

-//
-// The certificate authority must have been restarted and the saved certificates for the
-// admin and application user are not valid. Deleting the wallet store will force these to be reset
-// with the new certificate authority.

-# Gradle start up script for POSIX generated by Gradle.
-#
-# Important for running:
-#
-# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
-# noncompliant, but you have some other compliant shell such as ksh or
-# bash, then to run this script, type that shell name before the whole
-# command line, like:
-#
-# ksh Gradle
-#
-# Busybox and similar reduced shells will NOT work, because this script
-# requires all of these POSIX shell features:
-# * functions;
-# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
-# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
-# * compound commands having a testable exit status, especially «case»;
-# * various built-in commands including «command», «set», and «ulimit».
-#
-# Important for patching:
-#
-# (2) This script targets any POSIX shell, so it avoids extensions provided
-# by Bash, Ksh, etc; in particular arrays are avoided.
-#
-# The "traditional" practice of packing multiple parameters into a
-# space-separated string is a well documented source of bugs and security
-# problems, so this is (mostly) avoided, by progressively accumulating
-# options in "$@", and eventually passing that to Java.
-#
-# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
-# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
-# see the in-line comments for details.
-#
-# There are tweaks for specific operating systems such as AIX, CygWin,
-# Darwin, MinGW, and NonStop.
-#
-# (3) This script is generated from the Groovy template
-# https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
-# within the Gradle project.

-# 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
-- GetAssetHashId
-- 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
- ```
-
-## 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
-```

-## Dutch auction
-
-This example allows you to run a [Dutch auction](https://en.wikipedia.org/wiki/Dutch_auction) that sells multiple items of the same good. All items are sold at the price that clears the auction. You also have the option of adding an auditor organization to the auction. If the organizations running the auction cannot agree, or encounter a technical error that prevents them from updating the auction, one of the auction participants can appeal to an auditor organization. The dutch auction smart contract provides an example of how create a complex signature policy by creating a protobuf and then using the policy for state based endorsement.
-
-This tutorial uses the example smart contract to run an auction in which a single seller wants to sell 100 tickets to multiple bidders. If you chose to add an auditor to the auction, you can appeal to the auditor to end the auction by overriding the standard auction endorsement policy.
-
-## Deploy the chaincode
-
-Change into the test network directory.
-```
-cd fabric-samples/test-network
-```
-
-If the test network is already running, run the following command to bring the network down and start from a clean initial state.
-```
-./network.sh down
-```
-
-You can then run the following command to deploy a new network.
-```
-./network.sh up createChannel -ca
-```
-
-Run the following command to deploy the dutch auction smart contract.
-```
-./network.sh deployCC -ccn auction -ccp ../auction-dutch/chaincode-go/ -ccep "OR('Org1MSP.peer','Org2MSP.peer')" -ccl go
-```
-
-Note that we deploy the smart contract with an endorsement policy of `"OR('Org1MSP.peer','Org2MSP.peer')" ` instead of using the default endorsement policy of the majority of orgs on the channel. Either Org1 or Org2 can create an auction without the endorsement of the other organization.
-
-## Add an auditor (optional)
-
-The smart contract allows you to add an auditor organization to the auction. The auditor can add bids, close the auction, or end the auction if participants cannot cooperate. In this tutorial, we will add the Org3 organization to the test network channel and install an auditor specific version of the dutch auction smart contract. This allows you to use Org3 as the auditor organization.
-
-From the `test-network` directory, issue the following commands to add Org3 to the channel:
-
-```
-cd addOrg3
-./addOrg3.sh up
-```
-
-Navigate back to the test network directory:
-```
-cd ..
-```
-
-Set the following environment to interact with the test network as Org3.
-```
-export PATH=${PWD}/../bin:$PATH
-export FABRIC_CFG_PATH=${PWD}/../config/
-export CORE_PEER_TLS_ENABLED=true
-export CORE_PEER_LOCALMSPID=Org3MSP
-export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org3.example.com/peers/peer0.org3.example.com/tls/ca.crt
-export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org3.example.com/users/Admin@org3.example.com/msp
-export CORE_PEER_ADDRESS=localhost:11051
-```
-
-To deploy the smart contract on the Org3 peer, we need to use the peer lifecycle chaincode commands to install the chaincode package and approve the chaincode definition as Org3. Run the following command to package the auditor version of the dutch auction smart contract:
-```
-peer lifecycle chaincode package auction.tar.gz --path ../auction-dutch/chaincode-go-auditor/ --lang golang --label auction_1
-```
-Install the chaincode package on the Org3 peer:
-```
-peer lifecycle chaincode install auction.tar.gz
-```
-
-The next step is to approve the chaincode as the Org3 admin. This requires getting the package ID of the chaincode that we just installed.
-```
-peer lifecycle chaincode queryinstalled
-```
-
-The command should return a response similar to the following:
-```
-Installed chaincodes on peer:
-Package ID: auction_1:8f0d6b6b5a616a1c2b6a9268418f2ee65718acc3c07ea12e123b189b3fb4fb14, Label: auction_1
-```
-
-Save the package ID returned by the command above as an environment variable. The package ID will not be the same for all users, so you need to complete this step using the package ID returned from your console.
-```
-export CC_PACKAGE_ID=auction_1:8f0d6b6b5a616a1c2b6a9268418f2ee65718acc3c07ea12e123b189b3fb4fb14
-```
-
-You can now approve the auction chaincode for Org3:
-```
-peer lifecycle chaincode approveformyorg -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls --cafile "${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem" --channelID mychannel --name auction --version 1.0 --package-id $CC_PACKAGE_ID --sequence 1 --signature-policy "OR('Org1MSP.peer','Org2MSP.peer')"
-```
-
-The command will start the dutch auction chaincode on the Org3 peer. Note that we did not update the endorsement policy before we added the auditor organization. Only Org1 and Org2 will be able create an auction. The auditor is added the endorsement policy after the auction is created. Because the auditor does not need to create an auction or create new bids, the auditor can run a different version of the smart contract than the auction participants. The auditor version of the smart contract also adds logic to check that the request is submitted by one of the auction participants before the auditor can intervene.
-
-## Install the application dependencies
-
-We will run the dutch auction using a series of Node.js applications. Change into the `application-javascript` directory:
-```
-cd fabric-samples/auction-dutch/application-javascript
-```
-
-From this directory, run the following command to download the application dependencies if you have not done so already:
-```
-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 tickets. 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 two bidders from Org1 and another three bidders from Org2:
-```
-node registerEnrollUser.js org1 bidder1
-node registerEnrollUser.js org1 bidder2
-node registerEnrollUser.js org2 bidder3
-node registerEnrollUser.js org2 bidder4
-node registerEnrollUser.js org2 bidder5
-```
-
-## Create the auction
-
-The seller from Org1 would like to create an auction to sell 100 tickets. Run the following command to use the seller wallet to run the `createAuction.js` application. The seller needs to provide an auction ID, the item to be sold, and the quantity to be sold to create the auction. The seller uses `withAuditor` to indicate that Org3 will be added as the auditor organization. If you do not want to add an auditor, you can provide a value of `noAuditor`. You will see the application query the auction after it is created.
-```
-node createAuction.js org1 seller auction1 tickets 100 withAuditor
-```
-
-Adding an auditor to the auction creates an endorsement policy with the auditor included. Without the auditor, each organization with sellers or bidders participating in the auction is added to the auction endorsement policy. For example, if the auction had two organizations participating in the auction, the auction endorsement policy would be `AND(Org1, Org2)`. However, if the selling organization decides to add an auditor, the auditor organization would be added to the endorsement policy. If the participating organizations disagree, or if a participant has a technical problem, the auditor can join any one of the participating organizations and agree to update the auction. Extending the example above, if the auction with two organizations added an auditor, the auction endorsement policy would be `OR(AND(Org1, Org2), AND(auditor, OR(Org1, Org2)))`.
-
-## 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 50 tickets for 80 dollars.
-```
-node bid.js org1 bidder1 auction1 50 80
-```
-
-The application will query the bid after it is created:
-```
-*** Result: Bid: {
- "objectType": "bid",
- "quantity": 50,
- "price": 80,
- "org": "Org1MSP",
- "buyer": "x509::CN=bidder1,OU=client+OU=org1+OU=department1::CN=ca.org1.example.com,O=org1.example.com,L=Durham,ST=North Carolina,C=US"
-}
-```
-
-The `bid.js` application also prints the bidID:
-```
-*** Result ***SAVE THIS VALUE*** BidID: 6630e1bb06e827a2b77023f63677fae8a0ad43126730e450d3252fa58eeb85b1
-```
-
-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=6630e1bb06e827a2b77023f63677fae8a0ad43126730e450d3252fa58eeb85b1
-```
-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 auction1 $BIDDER1_BID_ID
-```
-
-The hash of bid is added to the list of private bids in that have been submitted to `auction1`. Storing the hash on the public auction ledger allows users to prove the accuracy of the bids they reveal once bidding is closed. The application queries the auction to verify that the bid was added:
-```
-*** Result: Auction: {
- "objectType": "auction",
- "item": "tickets",
- "seller": "x509::CN=seller,OU=client+OU=org1+OU=department1::CN=ca.org1.example.com,O=org1.example.com,L=Durham,ST=North Carolina,C=US",
- "quantity": 100,

- "Org1MSP"
- ],
- "privateBids": {
- "\u0000bid\u0000auction1\u00006630e1bb06e827a2b77023f63677fae8a0ad43126730e450d3252fa58eeb85b1\u0000": {

- }
- },
- "revealedBids": {},
- "winners": [],
- "price": 0,
- "status": "open",
- "auditor": true
-}
-```
-
-### Bid as bidder2
-
-Let's submit another bid. Bidder2 would like to purchase 40 tickets for 50 dollars.
-```
-node bid.js org1 bidder2 auction1 40 50
-```
-
-Save the Bid ID returned by the application:
-```
-export BIDDER2_BID_ID=5796569dae2e95242eadc5cf1cf8aa24f5ae072d801e7decb2547530de5a65e8
-```
-
-Submit bidder2's bid to the auction:
-```
-node submitBid.js org1 bidder2 auction1 $BIDDER2_BID_ID
-```
-
-### Bid as bidder3 from Org2
-
-Bidder3 will bid for 30 tickets at 70 dollars:
-```
-node bid.js org2 bidder3 auction1 30 70
-```
-
-Save the Bid ID returned by the application:
-```
-export BIDDER3_BID_ID=d52ea4d9b4bc428d395db2d68323bc12cc9b5c1f8617900f459ccd41c38d3c0a
-```
-
-Add bidder3's bid to the auction:
-```
-node submitBid.js org2 bidder3 auction1 $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": "tickets",
- "seller": "x509::CN=seller,OU=client+OU=org1+OU=department1::CN=ca.org1.example.com,O=org1.example.com,L=Durham,ST=North Carolina,C=US",

- "revealedBids": {},
- "winners": [],
- "price": 0,
- "status": "open",
- "auditor": true
-}
-```
-
-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 the `"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 15 tickets for 60 dollars:
-```
-node bid.js org2 bidder4 auction1 15 60
-```
-
-Save the Bid ID returned by the application:
-```
-export BIDDER4_BID_ID=c6464f984bb01e639a46e58b94c496e8bbd829b5e4fa7ffcc150d9a565d45684
-```
-
-Add bidder4's bid to the auction:
-```
-node submitBid.js org2 bidder4 auction1 $BIDDER4_BID_ID
-```
-
-### Bid as bidder5
-
-Bidder5 from Org2 will bid for 20 tickets at 60 dollars:
-```
-node bid.js org2 bidder5 auction1 20 60
-```
-
-Save the Bid ID returned by the application:
-```
-export BIDDER5_BID_ID=f4024ab09b4dacf0a636927414850dde2a2a5e8ec4601e2a0071f5c233248207
-```
-
-Add bidder5's bid to the auction:
-```
-node submitBid.js org2 bidder5 auction1 $BIDDER5_BID_ID
-```
-
-
-## Close the auction
-
-Now that all five 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 auction1
-```
-
-The application will query the auction to allow you to verify that the auction status has changed to closed.
-
-## 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 auction1 $BIDDER1_BID_ID
-```
-
-The full bid details, including the quantity and price, are now visible:
-```

-We will add three more bidders, the second bidder from Org1 and two bidders from Org2. Run the following commands to reveal the bidders:
-```
-node revealBid.js org1 bidder2 auction1 $BIDDER2_BID_ID
-node revealBid.js org2 bidder4 auction1 $BIDDER4_BID_ID
-node revealBid.js org2 bidder5 auction1 $BIDDER5_BID_ID
-```
-
-Let's try to end the auction using the seller identity and see what happens.
-
-```
-node endAuction.js org1 seller auction1
-```
-
-The output should look something like the following:
-
-```
---> Submit the transaction to end the auction
-2021-01-28T16:47:27.501Z - error: [DiscoveryHandler]: compareProposalResponseResults[undefined] - read/writes result sets do not match index=1
-2021-01-28T16:47:27.503Z - error: [Transaction]: Error: No valid responses from any peers. Errors:
- peer=undefined, status=grpc, message=Peer endorsements do not match
-******** FAILED to submit bid: Error: No valid responses from any peers. Errors:
- peer=undefined, status=grpc, message=Peer endorsements do not match
-```
-
-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 the price that would clear the auction with the currently revealed bids is lower than the bid of Bidder3, the Org2 peer refuses to endorse the transaction that would end the auction.
-
-In order to end the auction, Org1 would either need to wait for Org2 to reveal the final bid or appeal to the auditor. Depending on if you created the organization with an auditor, you can end the auction with either set of steps.
-
-## End the auction using an auditor
-
-If Org2 is unable to endorse the transaction to end the auction, Org1 can ask the auditor to intervene. The following program gets an endorsement from the Org3 auditor and Org1 to end the auction. As a result, the transaction would meet the auditor component of the state based endorsement policy.
-```
-node endAuctionwithAuditor org1 seller auction1
-```
-
-Even though Org2 has not agreed to the end of the auction, the endorsement Org1 is sufficient to end the auction if the auditor agrees. As part of ending the auction, both Org1 and the auditor need to calculate the same price and the same set of winners. Each winning bidder is listed next to the quantity that was allocated to them.

-The auction allocates tickets to the highest bids first. Because all 100 tickets are sold after allocating tickets to the bid that was submitted at 50, 50 is the `"price"` that clears the auction.

-## End the auction without an auditor
-
-If we did not add an auditor to the auction, we need to add the remaining bid so that Org2 will endorse ending the auction.
-```
-node revealBid.js org2 bidder3 auction1 $BIDDER3_BID_ID
-```
-
-Now that all the winning bids have been revealed, we can submit the transaction to end the auction once more.
-```
-node endAuction org1 seller auction1

-The transaction was successfully endorsed by both Org1 and Org2, who both calculated the same price and winners of the auction. Each winning bidder is listed next to the quantity that was allocated to them.

-The auction allocates tickets to the highest bids first. Because all 100 tickets are sold after allocating tickets to the bids that were submitted at 60, 60 is the `"price"` that clears the auction. The first 80 tickets are allocated to Bidder1 and Bidder3. The remaining 20 tickers are allocated to Bidder4 and Bidder5. When bids are tied, the auction smart contract fills the smaller bids first. As a result, Bidder4 is awarded their full bid of 15 tickets, while Bidder5 is allocated the remaining 5 tickets.
-
-## 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-dutch/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
-````

-## 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-simple/chaincode-go/ -ccl 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-simple/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": "x509::CN=seller,OU=client+OU=org1+OU=department1::CN=ca.org1.example.com,O=org1.example.com,L=Durham,ST=North Carolina,C=US",
- "organizations": [
- "Org1MSP"
- ],
- "privateBids": {},
- "revealedBids": {},
- "winner": "",
- "price": 0,
- "status": "open"
-}
-```
-The smart contract uses the `GetClientIdentity().GetID()` API to read the identity that creates the auction and defines that identity as the auction `"seller"`. The seller is identified by the name and issuer of the seller's certificate.
-
-## 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": "x509::CN=bidder1,OU=client+OU=org1+OU=department1::CN=ca.org1.example.com,O=org1.example.com,L=Durham,ST=North Carolina,C=US"
-}
-```
-
-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: 67d85ef08e32de20994c816362d0952fe5c2ae3f2d1083600c3ac61f65a89f60
-```
-
-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=67d85ef08e32de20994c816362d0952fe5c2ae3f2d1083600c3ac61f65a89f60
-```
-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": "x509::CN=seller,OU=client+OU=org1+OU=department1::CN=ca.org1.example.com,O=org1.example.com,L=Durham,ST=North Carolina,C=US",

- }
- },
- "revealedBids": {},
- "winner": "",
- "price": 0,
- "status": "open"
-}
-```
-
-### 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=0fa8b3b15923966f205a1f5ebd163d2707d069ffa055105114fc654d225f511d
-```
-
-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=cda8bb2849fc0553efb036c56ea86d82791a695b5641941dac797dc6e2d75768
-```
-
-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": "x509::CN=seller,OU=client+OU=org1+OU=department1::CN=ca.org1.example.com,O=org1.example.com,L=Durham,ST=North Carolina,C=US",

- }
- },
- "revealedBids": {},
- "winner": "",
- "price": 0,
- "status": "open"
-}
-```
-
-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=83861eb17715ff537a1e73cd2d08509dc7199572806a5368706516759af1a257
-```
-
-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
-```
-
-The full bid details, including the price, are now visible:
-```

-
-Bidder3 from Org2 will also reveal their bid:

-
-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
-2021-01-28T16:47:27.501Z - error: [DiscoveryHandler]: compareProposalResponseResults[undefined] - read/writes result sets do not match index=1

- peer=undefined, status=grpc, message=Peer endorsements do not match
-******** FAILED to submit bid: Error: No valid responses from any peers. Errors:
- peer=undefined, status=grpc, message=Peer endorsements do not match
-```
-
-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-simple/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
-````

-# Fabric Full Stack Development Workshop
-
-
-
-Hyperledger Fabric can be used to represent assets of any kind on a permissioned decentralized ledger, from fungible tokens to non-fungible tokens, including monetary products, marbles, pineapples, classic cars, fine art, and anything else you can imagine.
-Fabric can be used to track and update anything about these assets, common examples include asset ownership, exchange, provenance, and lifecycle.
-
-This workshop will demonstrate how a generic asset transfer solution can be modeled and deployed to take advantage of a blockchains qualitites of service.
-
-The workshop will be split into three sections:
-- Smart Contract Development
-- Client Application Development
-- Cloud Native Fabric Deployment
-
-
-
-**OBJECTIVES:**
-
-- Show how an Asset Transfer smart contract can be written to encapsulate business logic
- - Show how the smart contract can be developed iteratively to get correct function in a development context
-- Show how client applications can be written using the Gateway functionality
- - Show how the simplification of the Gateway programming model makes connecting applications more streamlined
- - Show how this streamlined approach improves resilience and availability
-- Show how the solution can then be deployed to a production-class environment
- - Show how a Hyperledger Fabric network can be created and managed in Kubernetes (K8S) using automation
- - Show how the Fabric Operator and Console can be installed via Ansible playbooks
- - Show how a multi-organization configuration of Fabric can be created
-
----
-
-**Please ensure you've got the [required tools](./SETUP.md) on your local machine or in a virtual machine -- To check, run `./check.sh`**
-
----
-
-
-## Before you begin....
-
-Fabric is a multi-server decentralized system with orderer and peer nodes, so it can be quite complex to configure. Even the simplest smart contract needs a running Fabric Infrastructure and one size does not fit all.
-
-There are configurations that can run Fabric either as local binaries, in a single docker container, in multiple containers, or in K8S.
-This workshop will show some of the approaches that can be used for developing applications and contracts with a minimal Fabric environment (Microfab), and how a production deployment can be achieved.
-There are other ways of deploying Fabric produced by the community - these are equally valid and useful. Feel free to try the others, once you understand the basic concepts to find what works best for you.
-
-At a high-level remember that a solution using Fabric has (a) client application to send in transaction requests (b) Fabric infrastructure to service those requests (c) Smart Contract to action the transactions.
-The nature of (b) the fabric infrastructure will change depending on your scenario; start simple and build up. The smart contracts and client application's code will remain the same no matter the way Fabric is provisioned.
-There will be minor variations in deployment (eg local docker container vs remote K8S cluster) but fundamentally the process is the same.
-
-## Running the workshop
-
- If you're running on Windows, please check the [hints and tips](./docs/tips-for-windows-dev.md)
-
-- Ensure you've got the tools you may need, either installed locally or in a multipass virtual machine. See the [setup page](./SETUP.md) for details.
-- Clone this repository to a convient location
-- We suggest that you open 3 or 4 terminal windows
- - One for running chaincode in dev mode
- - One for running the fabric infrastructure and optionally one for monitoring it
- - One for client applications
-
-- Work through the sections below in order, although you don't necessarily need to complete all the Exercises before moving to the next section.
-
----
-## Scenario
-
-Lets assume the assets you are tracking on the blockchain ledger are trading cards. Each trading card represents a comic book character and has an id, size, favorite color, and owner.
-These trading cards can be passed between people, with some cards having more 'value' due to rarity or having notable attributes.
-
-In token terms, think of these cards as non-fungible tokens. Each card has different attributes and individual cards can't be subdivided.
-
-We'll create a digital representation of these cards on the blockchain ledger. There are a few important aspects of this solution to consider:
-
-- Ledger - The blockchain ledger on each peer maintains the current state of each card (asset), as well as the history of transactions that led to the current state, so that there is no doubt about the assets issuance, provenance, attributes, and ownership.
-- Asset transfer smart contract - manage changes to asset state such as the transfer of cards between people
-- Organizations - Since this is a permissioned blockchain we'll model the participants as organizations that are authorized to run nodes or transact on the Fabric network. Our simple network will consist of an ordering service organization and two transacting organizations.
- - Ordering service organization - runs the ordering service to ensure transactions get ordered into blocks fairly, this may be a consortium leader or regulator in the industry. Note that ordering service nodes could also be contributed from multiple organizations, this becomes especially important when running a Byzantine Fault Tolerant (BFT) ordering service.
- - Owner Organizations - Each owner organization is authorized to run peers and submit transfer transactions for the cards (assets) that they own.

-# Essential Setup
-
-Remember to clone this repository!
-
-```shell
-git clone https://github.com/hyperledger/fabric-samples.git fabric-samples
-cd fabric-samples/full-stack-asset-transfer-guide
-export WORKSHOP_PATH=$(pwd)
-```
-
-> to check the tools you already have `./check.sh`
-
-## Option 1: Use local environment
-
-Do you want to configure your local environment with the workshop dependencies?
-
-- To develop an application and/or contract (first two parts of workshop) follow the *DEV* setup below
-
-- To deploy a chaincode to kubernetes in a production manner (third part of workshop) follow the *PROD* setup below
-
-## Option 2: Use a Multipass Ubuntu image
-
-If you do not want to install dependencies on your local environment, you can use a Multipass Ubuntu image instead.
-
-Tip - You may need to stop any VPN client for the Multipass networking to work.
-
-- [Install multipass](https://multipass.run/install)
-
-- Launch the virtual machine and automatically install the workshop dependencies:
-
-```shell
-multipass launch \
- --name fabric-dev \
- --disk 80G \
- --cpus 8 \
- --mem 8G \
- --cloud-init infrastructure/multipass-cloud-config.yaml
-```
-
-- Mount the local workshop to your multipass vm:
-
-```shell
-multipass mount $PWD fabric-dev:/home/ubuntu/full-stack-asset-transfer-guide
-```
-
-- Open a shell on the virtual machine:
-
-```shell
-multipass shell fabric-dev
-```
-
-Tip - The vm creation log can be seen at /var/log/cloud-init-output.log if you need to troubleshoot anything.
-
-- You are now inside the virtual machine. cd to the workshop directory:
-
-```shell
-cd full-stack-asset-transfer-guide
-```
-
-- Install Fabric peer CLI and set environment variables
-```shell
-curl -sSLO https://raw.githubusercontent.com/hyperledger/fabric/main/scripts/install-fabric.sh && chmod +x install-fabric.sh
-./install-fabric.sh binary
-export WORKSHOP_PATH=$(pwd)
-export PATH=${WORKSHOP_PATH}/bin:$PATH
-export FABRIC_CFG_PATH=${WORKSHOP_PATH}/config
-```
-
-Note - You'll probably want three terminal windows for running the workshop, go ahead and open the shells now:
-
-```shell
-multipass shell fabric-dev
-```
-
-- Eventual cleanup - To remove the multipass image when you are done with it after the workshop:
-```shell
-multipass delete fabric-dev
-multipass purge
-multipass list
-```
-
-## DEV - Required Tools
-
-You will need a set of tools to assist with chaincode and application development.
-We'll assume you are developing in Node for this workshop, but you could also develop in Java or Go by installing the respective compilers.

-# Conga Cards
-
-This Gateway Client application will listen for chaincode events, invoking a [#discord webhook](https://discord.com/developers/docs/resources/webhook)
-to post a channel message when [Conga Cards](assets/) are created, deleted, and exchanged on a channel.
-
-> [Conga Comics](https://congacomic.github.io) | Life on the chain, one block at a time by Ed Moffatt & some friends
-
-This project is based on the [trader-typescript](../trader-typescript) sample Gateway Client application.
-
-
-## Prerequisites
-
-The client application requires Node.js 16 or later.
-
-## Set up
-
-The following steps prepare the client application for execution:
-
-1. Ensure the [asset-transfer](../../contracts/asset-transfer-typescript/) smart contract is deployed to a running Fabric network.
-1. Run `npm install` to download dependencies and compile the application code.
-
-> **Note:** After making any code changes to the application, be sure to recompile the application code. This can be done by explicitly running `npm install` again, or you can leave `npm run build:watch` running in a terminal window to automatically rebuild the application on any code change.
-
-
-The client application uses environment variables to supply configuration options. You must set the following environment variables when running the application:
-
-- `ENDPOINT` - endpoint address for the Gateway service to which the client will connect in the form **hostname:port**. Depending on your environment, this can be the address of a specific peer within the user's organization, or an ingress endpoint that dispatches to any available peer in the user's organization.
-- `MSP_ID` - member service provider ID for the user's organization.
-- `CERTIFICATE` - PEM file containing the user's X.509 certificate.
-- `PRIVATE_KEY` - PEM file containing the user's private key.
-
-The following environment variables are optional and can be set if required by your environment:
-
-- `CHANNEL_NAME` - Channel to which the chaincode is deployed. (Default: `mychannel`)
-- `CHAINCODE_NAME` - Channel to which the chaincode is deployed. (Default: `asset-transfer`)
-- `TLS_CERT` - PEM file containing the CA certificate used to authenticate the TLS connection to the Gateway peer. *Only required if using a TLS connection and a private CA.*
-- `HOST_ALIAS` - the name of the Gateway peer as it appears in its TLS certificate. *Only required if the endpoint address used by the client does not match the address in the Gateway peer's TLS certificate.*
-
-- `WEBHOOK_URL` - the [#discord webhook](https://discord.com/developers/docs/resources/webhook) to which the channel
- events will be relayed.
-
-
-# Run
-
-The sample application is run as a command-line application, and is lauched using `npm start [ ...]`. The following commands are available:
-
-- `npm start create ` to create a new asset.
-- `npm start delete ` to delete an existing asset.
-- `npm start getAllAssets` to list all assets.
-- `npm start read ` to view an existing asset.
-- `npm start transfer ` to transfer an asset to a new owner within an organization MSP ID.
-- `npm start discord` starts an event loop, relaying channel events to `${WEBHOOK_URL}`
-
-
-## Sample Interaction:
-
-- Submit some transactions to a ledger:
-```shell
-npm start create blockbert SeanB orange
-
-npm start create count-blockula jkneubuhl Org1MSP purple
-
-npm start transfer count-blockula davidboswell Org1MSP
-```
-
-- Run the discord event listener:
-```shell
-export WEBHOOK_URL="https://discord.com/api/webhooks/123456789/xyzzy-abcdef-12345"
-
-npm start discord
-```
