Please keep in mind VSC is a completely separate project from SPK/DLux. VSC is being built completely from the ground up and no such forking has occurred. We are building VSC to be a powerful smart contract core for all HIVE DAPPs not just SPK, or any of the like. In comparison, Dlux is primarily a project specific L2 network, whereas VSC is meant to be a hive engine replacement and successor. The intent here is to build technology anyone can use for NFTs, tokens, airdrops, backends, wrapping, etc, and make that as open and freely available as possible plus provide sophisticated tools to tackle onboarding and scalability.
Everything is public on our github repo: https://github.com/vsc-eco/vsc-node
Feel free to ask me any further questions, I'd be happy to answer.
