Candy
Candy is a fork of tendermint. It combines fabric chaincode to implement smart contracts.
Minimum requirements
| Requirement | Notes |
|---|---|
| Go version | Go1.13 or higher |
Install
make cenv
make install
How to use
The way of writing candy contract is the same as fabric chaincode, but only support golang.
NOTE: please use wjbbig/candy-contract-api as a dependency to write your contract. It is a simplified version of fabric/fabric-contract-api-go and only retains database operations.
You can use the following command to package your contract:
candy package -p /the path of your contract -o xxx.tar.gz -l golang
Before you install the contract, you have to start at least one node:
candy node
then, use the following command to install the contract:
curl -s 'localhost:26657/contract_install?name="the name of your contract"'
NOTE: you only need to install the contract on one node, and other nodes will automatically receive the contract package and install it.
Finally, let's make a tx:
curl -s 'localhost:26657/broadcast_tx_commit?tx="contractname,functionname,args..."'
