Good to have you here. What is your view around private blockchains and smart contracts regarding Hyperledger Fabric vs Ethereum based ones? I mean, in my perspective there is no need to have smart contracts ala Ethereum because in a private blockchain you can simplify the problem to a workflow with states where the parties sign the different transitions and the logic can be outside a VM. Since private blockchains rely on a lot of oracles, those oracles are the weakest link in the security chain and the VM does not add significant security like in a public blockchain.
