Should questions that are specifically confined to the workings of Hyperledger Fabric be on topic?
- Hyperledger Fabric - Is it a Blockchain Framework or Blockchain Platform?
Previous meta discussion: What is really on-topic for Ethereum Stack Exchange?
I can see that questions comparing Fabric to Ethereum might be useful to some extent, so could be considered on-topic, but IMO questions about Fabric that are in no way connected to Ethereum should be considered off-topic.
Note that we have the hyperledger and hyperledger-fabric tags.
Hyperledger Fabric is one of the Hyperledger projects. It provides a plug-and-play framework for developing blockchain stuff. It doesn't support the EVM directly.
Hyperledger Burrow is another of their projects and includes an Apache-licensed Ethereum VM implementation.
(I'm unsure if Burrow is a sub-project of, and therefore built on top of, Fabric.)
