I'm developing a blockchain based system to provide energy certificates handled as tokens in hyperledger fabric. I've been doing some research but found no state of art on how to do this. If anyone can provide a useful link on how to bring this use case into hyperledger fabric tokens, I would be grateful. Also, I don't really know how to include the fabtoken functionality in an already deployed blockchain network. Any links or tips on how to start investigating for this will be welcome.
fabtoken was included in the fabric v2.0 alpha, but was reverted from git due to several issues. In other words, it is a method that is no longer supported.
Currently, fabric provides an example implemented in chaincode as a related token. See the link below.
