token

Shows the use of shim functions

• token.go V3 of token
• proposal.go Shows extraction of info from SignedProposal

Part-1

Demonstrates the use of stub.GetTxID(), stub.GetChannelID() and stub.GetTxTimestamp()

1. Init the environment

dev-init.sh

source set-env.sh acme

2. Install & Instantiate the chaincode

set-chain-env.sh -n token -p token/v3

chain.sh install -p

chain.sh instantiate

3. Start following the log

cc-logs.sh -f

4. Open a new terminal

. set-env.sh acme

chain.sh invoke

5. Check out the output in Terminal #1

Part-2

1. Install the latest version of the chaincode

chain.sh install-auto

set-chain-env.sh -s 2

chain.sh instantiate

2. Follow the logs

cc-logs.sh -f

3. Invoke the chaincode in terminal #2

chain.sh invoke

3. Observe the output in terminal #1
