# Test network - Nano bash
Test network Nano bash provides a set of minimal bash scripts to run a Fabric network on your local machine.
The network is functionally equivalent to the docker-based Test Network, you can therefore run all the tutorials and samples that target the Test Network with minimal changes.
The Fabric release binaries are utilized rather than using docker containers to avoid all unnecessary layers. Only the chaincode and chaincode builder runs in a docker container behind the scenes.
Using the Fabric binaries also makes it simple for Fabric developers to iteratively and quickly modify Fabric code and test a Fabric network as a user.
As the name `nano` implies, the scripts provide the smallest minimal setup possible for a Fabric network while still offering a multi-node TLS-enabled network:
- Minimal set of dependencies
- Minimal requirements on Fabric version (any v2.x orderer and peer nodes should work)
- Minimal set of environment variable overrides of the default orderer orderer.yaml and peer core.yaml configurations
- Minimal scripting with minimal set of reference commands to get a Fabric network up and running
- Minimal channel configuration for an orderer organization (3 ordering nodes) and two peer organizations (with two peers each)
- Minimal endorsement policy to allow a single organization to approve and commit a chaincode (unlike Test Network which requires both organizations to endorse)
# Prereqs
- Follow the Fabric documentation for the [Prereqs](https://hyperledger-fabric.readthedocs.io/en/latest/prereqs.html)
- Follow the Fabric documentation for [downloading the Fabric samples and binaries](https://hyperledger-fabric.readthedocs.io/en/latest/install.html). You can skip the docker image downloads by using `curl -sSL https://bit.ly/2ysbOFE | bash -s -- -d`
# Instructions for starting network
Open terminal windows for 3 ordering nodes, 4 peer nodes, and 4 peer admins as seen in the following terminal setup. The first two peers and peer admins belong to Org1, the latter two peer and peer admins belong to Org2.
Note, you can start with two ordering nodes and a single Org1 peer node and single Org1 peer admin terminal if you would like to keep things even more minimal (two ordering nodes are required to achieve consensus (2 of 3), while a single peer from Org1 can be utilized since the endorsement policy is set as any single organization).
![Terminal setup](terminal_setup.png)
The following instructions will have you run simple bash scripts that set environment variable overrides for a component and then runs the component.
The scripts contain only simple single-line commands so that they are easy to read and understand.
If you have trouble running bash scripts in your environment, you can just as easily copy and paste the individual commands from the script files instead of running the script files.
- cd to the `test-network-nano-bash` directory in each terminal window
- In the first orderer terminal, run `./generate_artifacts.sh` to generate crypto material (calls cryptogen) and system and application channel genesis block and configuration transactions (calls configtxgen). The artifacts will be created in the `crypto-config` and `channel-artifacts` directories.
- In the three orderer terminals, run `./orderer1.sh`, `./orderer2.sh`, `./orderer3.sh` respectively
- In the four peer terminals, run `./peer1.sh`, `./peer2.sh`, `./peer3.sh`, `./peer4.sh` respectively
- Note that each orderer and peer write their data (including their ledgers) to their own subdirectory under the `data` directory
- In the four peer admin terminals, run `source peer1admin.sh`, `source peer2admin.sh`, `source peer3admin.sh`, `source peer4admin.sh` respectively
Note the syntax of running the scripts. The peer admin scripts run with the `source` command in order to source the script files in the respective shells. This is important so that the exported environment variables can be utilized by any subsequent user commands.
The `peer1admin.sh` script sets the peer1 admin environment variables, creates the application channel `mychannel`, updates the channel configuration for the org1 gossip anchor peer, and joins peer1 to `mychannel`.
The remaining peer admin scripts join their respective peers to `mychannel`.
# Instructions for deploying and running the basic asset transfer sample chaincode
To deploy and invoke the chaincode, utilize the peer1 admin terminal that you have created in the prior steps.
Package and install the chaincode on peer1:
```
peer lifecycle chaincode package basic.tar.gz --path ../asset-transfer-basic/chaincode-go --lang golang --label basic_1
peer lifecycle chaincode install basic.tar.gz
```
The chaincode install may take a minute since the `fabric-ccenv` chaincode builder docker image will be downloaded if not already available on your machine.
Copy the returned chaincode package ID into an environment variable for use in subsequent commands (your ID may be different):
```
export CC_PACKAGE_ID=basic_1:faaa38f2fc913c8344986a7d1617d21f6c97bc8d85ee0a489c90020cd57af4a5
```
Approve and commit the chaincode (only a single approver is required based on the lifecycle endorsement policy of any organization):
```
peer lifecycle chaincode approveformyorg -o 127.0.0.1:6050 --channelID mychannel --name basic --version 1 --package-id $CC_PACKAGE_ID --sequence 1 --tls --cafile ${PWD}/crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/tls/ca.crt
peer lifecycle chaincode commit -o 127.0.0.1:6050 --channelID mychannel --name basic --version 1 --sequence 1 --tls --cafile "${PWD}"/crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/tls/ca.crt
```
Invoke the chaincode to create an asset (only a single endorser is required based on the default endorsement policy of any organization).
Then query the asset, update it, and query again to see the resulting asset changes on the ledger.
```
peer chaincode invoke -o 127.0.0.1:6050 -C mychannel -n basic -c '{"Args":["CreateAsset","1","blue","35","tom","1000"]}' --tls --cafile "${PWD}"/crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/tls/ca.crt
peer chaincode query -C mychannel -n basic -c '{"Args":["ReadAsset","1"]}'
peer chaincode invoke -o 127.0.0.1:6050 -C mychannel -n basic -c '{"Args":["UpdateAsset","1","blue","35","jerry","1000"]}' --tls --cafile "${PWD}"/crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/tls/ca.crt
peer chaincode query -C mychannel -n basic -c '{"Args":["ReadAsset","1"]}'
```
Congratulations, you have deployed a minimal Fabric network! Inspect the scripts if you would like to see the minimal set of commands that were required to deploy the network.
Utilize `Ctrl-C` in the orderer and peer terminal windows to kill the orderer and peer processes. You can run the scripts again to restart the components with their existing data, or run `./generate_artifacts` again to clean up the existing artifacts and data if you would like to restart with a clean environment.

# SECTION: Capabilities
#
# - This section defines the capabilities of fabric network. This is a new
# concept as of v1.1.0 and should not be utilized in mixed networks with
# v1.0.x peers and orderers. Capabilities define features which must be
# present in a fabric binary for that binary to safely participate in the
# fabric network. For instance, if a new MSP type is added, newer binaries
# might recognize and validate the signatures from this type, while older
# binaries without this support would be unable to validate those
# transactions. This could lead to different versions of the fabric binaries
# having different world states. Instead, defining a capability for a channel
# informs those binaries without this capability that they must cease
# processing transactions until they have been upgraded. For v1.0.x if any
# capabilities are defined (including a map with all capabilities turned off)
# then the v1.0.x peer will deliberately crash.

# ERC-1155 Chaincode
This is a sample ERC-1155 chaincode written in Go.
ERC-20 is the standard for fungible tokens. ERC-721 is the standard for non-fungible tokens. ERC-1155 is the standard for multiple tokens (both fungible and non-fungible). [More information about the ERC-1155 standard can be found here.](https://eips.ethereum.org/EIPS/eip-1155)
## Architecture
This implementation aims for high throughput by minimizing key collisions. The balance of accounts is distributed over multiple keys. The token transfers can be batched using the batched versions of functions (e.g. BatchTransferFrom, BalanceOfBatch). Since ERC-1155 is account-based, the interface of the chaincode is account-based. However, since the balances are distributed over multiple keys, the chaincode has a model similar to a UTXO-based chaincode internally.
In this chaincode, one organization has a minter/burner role just like in the [ERC-20 example in this repository](https://github.com/hyperledger/fabric-samples/tree/main/token-erc-20).
## Functions Implemented
The following required functions of ERC-1155 are implemented:
- safeTransferFrom
- safeBatchTransferFrom
- balanceOf
- balanceOfBatch
- setApprovalForAll
- isApprovedForAll
Note: The "safe" prefix is omitted from "TransferFrom" in the implementation because the prefix is related to some issue about backwards compatibility with older smart contracts in Ethereum.
Note: TransferFrom is used to send a single token type between two users. BatchTransferFrom is used to send multiple tokens between two users. So, BatchTransferFrom is a more general form of TransferFrom. Ethereum defined two functions instead of one because this reduces gas costs. Since there is no gas cost in Fabric, implementing these two functions is unnecessary. Nevertheless, both of them are implemented to to conform the ERC-1155 standard.
## Additional Functions Implemented
The following additional functions are also implemented. The following paragraphs give the reasoning behind adding these functions:
- Optional Metadata URI extension:
Defined in ERC-1155 but not required. Allows one to set a URI for tokens and get the URI.
- SetURI
- URI
- Mint/Burn extension:
Although Mint / Burn are not required, they are necessary to change the supply of tokens, create new fungible or non-fungible tokens. In a real implementation, they will be implemented unless the supply of the tokens is fixed beforehand. MintBatch / BurnBatch is only implemented to complement the TransferFrom/BatchTransferFrom. Actually, using only MintBatch and BurnBatch would be enough.
- Mint
- MintBatch
- Burn
- BurnBatch
- Extra/utility functions
- BatchTransferFromMultiRecipient: This is not defined in the standard. We created this function to solve an issue we encountered. It is only required if a person wants to send tokens to multiple persons in a blockchain block. If a person doesn't use this function and create two transactions in a single block, there will be key conflicts because the chaincode will try to decrement the balance of the sender twice in a block and this causes a key conflict in Fabric [just like explained in here](https://github.com/hyperledger/fabric-samples/tree/main/high-throughput). This problem does not exist in Ethereum because, in Ethereum, the transactions are ordered before they are executed.
- BroadcastTokenExistence: Explained in ERC-1155 but it is not required. It is only used if a token minter wants to announce the existence of a token without minting it.
- ClientAccountID: This function is special for Fabric because we do not have wallet addresses in Fabric and users need to know their account ID to transfer tokens.
- ClientAccountBalance: A shorthand for BalanceOf function.
## Example Usage
### Launch test network
Open a command terminal and navigate to the test network directory.
```bash
cd fabric-samples/test-network
```
Clean up the existing network if you have any.
```bash
./network.sh down
```
Start test network
```bash
./network.sh up createChannel -ca
```
### Deploy chaincode
Deploy ERC-1155 chaincode.
```bash
./network.sh deployCC -ccn erc1155 -ccp ../token-erc-1155/chaincode-go/ -ccl go
```
### Register identities
In this example, there are two organizations (org). We will register 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.
We need to set the following environment variables to use the Fabric CA client (and subsequent commands). The first command sets Fabric config path. The second command adds Fabric CLI utilities to path.
```bash
export FABRIC_CFG_PATH=${PWD}/../config/
export PATH=${PWD}/../bin:$PATH
```
The terminal we have been using will represent Org1. We will use the Org1 CA to create a new identity. Set the Fabric CA client home to the MSP of the Org1 CA admin (this identity was generated by the test network script).
```bash
export FABRIC_CA_CLIENT_HOME=${PWD}/organizations/peerOrganizations/org1.example.com/
```
Register `Person1` identity to Org1.
```bash
fabric-ca-client register --caname ca-org1 --id.name person1 --id.secret person1pw --id.type client --tls.certfiles "${PWD}/organizations/fabric-ca/org1/tls-cert.pem"
```
Generate the identity certificates and MSP folder.
```bash
fabric-ca-client enroll -u https://person1:person1pw@localhost:7054 --caname ca-org1 -M "${PWD}/organizations/peerOrganizations/org1.example.com/users/person1@org1.example.com/msp" --tls.certfiles "${PWD}/organizations/fabric-ca/org1/tls-cert.pem"
```
Copy the Node OU configuration file into the identity MSP folder.
```bash
cp "${PWD}/organizations/peerOrganizations/org1.example.com/msp/config.yaml" "${PWD}/organizations/peerOrganizations/org1.example.com/users/person1@org1.example.com/msp/config.yaml"
```
Open a new terminal to represent Org2 and navigate to fabric-samples/test-network. We'll use the Org2 CA to create the Org2 identities. Set the Fabric CA client home to the MSP of the Org2 CA admin.
```bash
cd fabric-samples/test-network
export FABRIC_CFG_PATH=${PWD}/../config/
export PATH=${PWD}/../bin:$PATH
export FABRIC_CA_CLIENT_HOME=${PWD}/organizations/peerOrganizations/org2.example.com/
```
Register `Person2`, `Person3`, `Person4`, `Person5` to Org2.
```bash
fabric-ca-client register --caname ca-org2 --id.name person2 --id.secret person2pw --id.type client --tls.certfiles "${PWD}/organizations/fabric-ca/org2/tls-cert.pem"
fabric-ca-client enroll -u https://person2:person2pw@localhost:8054 --caname ca-org2 -M "${PWD}/organizations/peerOrganizations/org2.example.com/users/person2@org2.example.com/msp" --tls.certfiles "${PWD}/organizations/fabric-ca/org2/tls-cert.pem"
cp "${PWD}/organizations/peerOrganizations/org2.example.com/msp/config.yaml" "${PWD}/organizations/peerOrganizations/org2.example.com/users/person2@org2.example.com/msp/config.yaml"
fabric-ca-client register --caname ca-org2 --id.name person3 --id.secret person3pw --id.type client --tls.certfiles "${PWD}/organizations/fabric-ca/org2/tls-cert.pem"
fabric-ca-client enroll -u https://person3:person3pw@localhost:8054 --caname ca-org2 -M "${PWD}/organizations/peerOrganizations/org2.example.com/users/person3@org2.example.com/msp" --tls.certfiles "${PWD}/organizations/fabric-ca/org2/tls-cert.pem"
cp "${PWD}/organizations/peerOrganizations/org2.example.com/msp/config.yaml" "${PWD}/organizations/peerOrganizations/org2.example.com/users/person3@org2.example.com/msp/config.yaml"
fabric-ca-client register --caname ca-org2 --id.name person4 --id.secret person4pw --id.type client --tls.certfiles "${PWD}/organizations/fabric-ca/org2/tls-cert.pem"
fabric-ca-client enroll -u https://person4:person4pw@localhost:8054 --caname ca-org2 -M "${PWD}/organizations/peerOrganizations/org2.example.com/users/person4@org2.example.com/msp" --tls.certfiles "${PWD}/organizations/fabric-ca/org2/tls-cert.pem"
cp "${PWD}/organizations/peerOrganizations/org2.example.com/msp/config.yaml" "${PWD}/organizations/peerOrganizations/org2.example.com/users/person4@org2.example.com/msp/config.yaml"
fabric-ca-client register --caname ca-org2 --id.name person5 --id.secret person5pw --id.type client --tls.certfiles "${PWD}/organizations/fabric-ca/org2/tls-cert.pem"
fabric-ca-client enroll -u https://person5:person5pw@localhost:8054 --caname ca-org2 -M "${PWD}/organizations/peerOrganizations/org2.example.com/users/person5@org2.example.com/msp" --tls.certfiles "${PWD}/organizations/fabric-ca/org2/tls-cert.pem"
cp "${PWD}/organizations/peerOrganizations/org2.example.com/msp/config.yaml" "${PWD}/organizations/peerOrganizations/org2.example.com/users/person5@org2.example.com/msp/config.yaml"
```
### Get account ID
Go back to the Org1 terminal, we'll set the following environment variables to operate the peer CLI as the minter identity from Org1.
```bash
export CORE_PEER_TLS_ENABLED=true
export CORE_PEER_LOCALMSPID="Org1MSP"
export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.example.com/users/person1@org1.example.com/msp
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt
export CORE_PEER_ADDRESS=localhost:7051
export TARGET_TLS_OPTIONS=(-o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls --cafile "${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem" --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")
```
Get client account ID for Person1.
```bash
peer chaincode query -C mychannel -n erc1155 -c '{"function":"ClientAccountID","Args":[]}'
```
```
eDUwOTo6Q049cGVyc29uMSxPVT1jbGllbnQsTz1IeXBlcmxlZGdlcixTVD1Ob3J0aCBDYXJvbGluYSxDPVVTOjpDTj1jYS5vcmcxLmV4YW1wbGUuY29tLE89b3JnMS5leGFtcGxlLmNvbSxMPUR1cmhhbSxTVD1Ob3J0aCBDYXJvbGluYSxDPVVT
```
Client Account ID is a base64-encoded concatenation of the issuer and subject from the client identity's enrolment certificate.
You can decode it with the following command:
```bash
echo "eDUwOTo6Q049cGVyc29uMSxPVT1jbGllbnQsTz1IeXBlcmxlZGdlcixTVD1Ob3J0aCBDYXJvbGluYSxDPVVTOjpDTj1jYS5vcmcxLmV4YW1wbGUuY29tLE89b3JnMS5leGFtcGxlLmNvbSxMPUR1cmhhbSxTVD1Ob3J0aCBDYXJvbGluYSxDPVVT" | base64 --decode
```
```
x509::CN=person1,OU=client,O=Hyperledger,ST=North Carolina,C=US::CN=ca.org1.example.com,O=org1.example.com,L=Durham,ST=North Carolina,C=US
```
Set the client account IDs as environment variables on both of the terminals to make the subsequent commands more readable.
```bash
export P1="eDUwOTo6Q049cGVyc29uMSxPVT1jbGllbnQsTz1IeXBlcmxlZGdlcixTVD1Ob3J0aCBDYXJvbGluYSxDPVVTOjpDTj1jYS5vcmcxLmV4YW1wbGUuY29tLE89b3JnMS5leGFtcGxlLmNvbSxMPUR1cmhhbSxTVD1Ob3J0aCBDYXJvbGluYSxDPVVT"

```
### Mint tokens
Mint tokens by calling the MintBatch function in order to create 100 token1s, 200 token2s, 300 token3s, 150 token4s, 100 token5s, 100 token6s as Person P1 from organization 1.
```bash
peer chaincode invoke "${TARGET_TLS_OPTIONS[@]}" -C mychannel -n erc1155 -c "{\"function\":\"MintBatch\",\"Args\":[\"$P1\",\"[1,2,3,4,5,6]\",\"[100,200,300,150,100,100]\"]}" --waitForEvent
```
Query the tokens of Person1.
```bash
peer chaincode query -C mychannel -n erc1155 -c "{\"function\":\"BalanceOfBatch\",\"Args\":[\"[\\\"$P1\\\",\\\"$P1\\\",\\\"$P1\\\",\\\"$P1\\\",\\\"$P1\\\",\\\"$P1\\\"]\",\"[1,2,3,4,5,6]\"]}"
```
```
[100,200,300,150,100,100]
```
Side note: There may seem too many slashes in the previous command. It double escapes the quotes. One escape is to be able to use quotes in the `-c` argument of the command. The second escape is necessary to pass the account IDs as an array. Quote is needed since the elements of the array are strings.
### Transfer tokens
#### TransferFrom
Send Person P2 six token3s by calling TransferFrom as Person P1.
```bash
peer chaincode invoke "${TARGET_TLS_OPTIONS[@]}" -C mychannel -n erc1155 -c "{\"function\":\"TransferFrom\",\"Args\":[\"$P1\",\"$P2\",\"3\",\"6\"]}" --waitForEvent
```
Get the new Balance of Person1 for token3.
```bash
peer chaincode query -C mychannel -n erc1155 -c "{\"function\":\"BalanceOf\",\"Args\":[\"$P1\",\"3\"]}"
```
```
294
```
Switch to the Org2 terminal and set the following environment variables.
```bash
export FABRIC_CFG_PATH=$PWD/../config/
export CORE_PEER_TLS_ENABLED=true
export CORE_PEER_LOCALMSPID="Org2MSP"
export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org2.example.com/users/person2@org2.example.com/msp
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt
export CORE_PEER_ADDRESS=localhost:9051
export TARGET_TLS_OPTIONS=(-o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls --cafile "${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem" --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")
```
Get the new balance of Person2 for token3.
```bash
peer chaincode query -C mychannel -n erc1155 -c "{\"function\":\"BalanceOf\",\"Args\":[\"$P2\",\"3\"]}"
```
```
6
```
#### BatchTransferFrom
Switch to the Org1 terminal.
Send Person P2 six token3s, three token4s, and one token2s by calling BatchTransferFrom as Person P1.
```bash
peer chaincode invoke "${TARGET_TLS_OPTIONS[@]}" -C mychannel -n erc1155 -c "{\"function\":\"BatchTransferFrom\",\"Args\":[\"$P1\",\"$P2\",\"[3,4,2]\",\"[6,3,1]\"]}" --waitForEvent
```
#### BatchTransferFromMultiReceipent
Call BatchTransferFromMultiReceipent as Person1 in order to send:
- six token5s to person P3,
- six token3s to person P4,
- three token4s to person P2,
- two token2s to person P5,
- and three token6s to person P2.
```bash
peer chaincode invoke "${TARGET_TLS_OPTIONS[@]}" -C mychannel -n erc1155 -c "{\"function\":\"BatchTransferFromMultiRecipient\",\"Args\":[\"$P1\",\"[\\\"$P3\\\",\\\"$P4\\\",\\\"$P2\\\",\\\"$P5\\\",\\\"$P2\\\"]\",\"[5,3,4,2,6]\",\"[6,6,3,2,3]\"]}" --waitForEvent
```
### Clean up
When you are finished, you can bring down the test network. This command will bring down the CAs, peers, and ordering node of the network that you created.
```bash
./network.sh down
```
