Re: failed to invoke chaincode name:"lscc" , error: container exited with 254 #fabric-chaincode #fabric-questions

Hey, I've had this problem before. What I did to solve it and seems bizarre is I created a new file and just simply copied and pasted the entire chaincode to the new file and used that.

Re: Not able to find Go in fabric-orderer container

Hey Siddharth, If you're trying to debug the peer binary, I would recommend eschewing the docker containers entirely and just running the peer binary directly on your computer, and using the standard

Re: Not able to find Go in fabric-orderer container

Go does exist in the parent docker image of the orderer i.e., hyperledger/fabric-baseimage root@2c068c753e05:/# find . -name

Re: Not able to find Go in fabric-orderer container

The go binary is not needed in that container, it is only needed to build it. You misapprehend what the go image is used for. On 10/25/2019 2:01 PM, Siddharth

Re: Second Channel

Unfortunately, the CLI for both the peer and the orderer is actually the same peer CLI. "peer channel join" talks to the peer whereas "peer channel create" talks to the orderer. Not my favorite

The system channel is on the orderer, not the peers. On 10/25/2019 7:09 AM, White, Spencer (S.) wrote:

Re: Second Channel

Is the system channel always the first channel that you create/define? And this would mean I need to follow a similar path as the adding org to existing channel i.e. getting the channel config, adding

Re: Second Channel

Ah ... so in that case you will first need to update the system channel with the new consortium definition prior to trying to create channel for that

Re: Major security hole in Hyperledger Fabric - Private Data is not private #fabric-chaincode #ssl #fabric #fabric-questions #fabric-dstorage

Ivan, I now understand your confusion. Your statement: "Private data is only known to the party sending the data hash and no one else (including members)." is incorrect. The chaincode can require that
