BurnableTokenInterface consists of Burn & BurnFrom

type Token

type Token struct{}

Token burnable implementation of BurnableTokenInterface

func (*Token) Burn

func (t *Token) Burn(stub shim.ChaincodeStubInterface,
	args []string,
	getTotalSupply func(stub shim.ChaincodeStubInterface) (*big.Int, error),
	getBalanceOf func(stub shim.ChaincodeStubInterface, args []string) (*big.Int, error),
) error

Burn destroys an amount of tokens of the invoking identity, and total supply.

* `args[0]` - the amount that will be burnt

func (*Token) BurnFrom

func (t *Token) BurnFrom(stub shim.ChaincodeStubInterface,
	args []string,
	getAllowance func(stub shim.ChaincodeStubInterface, args []string) (*big.Int, error),
	getTotalSupply func(stub shim.ChaincodeStubInterface) (*big.Int, error),
	getBalanceOf func(stub shim.ChaincodeStubInterface, args []string) (*big.Int, error),
) error

BurnFrom burns a specific amount of tokens from the target identity and total supply, the chaincode invoker must have sufficient allowance from burnee.

* `args[0]` - the ID of burnee.

* `args[1]` - the burn amount.
