CoCo framework - Queries
Just reading more about CoCo and couple of quick questions please: Does the framework allow deployments in private cloud shared between organizations ? What happens in environments without enclaves like Intel SFX? Does it allow for a pluggable consensus mechanism such that cryptlets continue to function ? Is there a transaction coordinator for transaction workflows that flow through many transaction-routers/ledger-adapters? Is there a controller module overseeing all the transactions ? How could I get my hands dirty with CoCo and is this the forum to discuss its architecture? cheers, Koshy

Prevent blockchain censorship on Azure
If someone creates a consortium or permissioned blockchain on Azure, how do other members prevent that subscription owner don't just delete all the associated resources to wipe out the information?

Azure template for HyperLedger Fabric may have certificate issue
I am not an HLF (or Azure) expert but I used the very nice wizard to set up an HLF V1 blockchain network. When I went in to the CA (Membership Services) VM, all looked good. What I found, however, is that it appears none of the peers (or the ordering service) can talk correctly to the MSP as it seems that the peer.pem referenced in this message is invalid. Did I miss a step? Has anyone else run into this? Thanks, panic: Fatal error when setting up MSP from directory /etc/hyperledger/fabric/msp/sampleconfig: err Could not load a valid signer certificate from directory /etc/hyperledger/fabric/msp/sampleconfig/signcerts, err Could not read directory open /etc/hyperledger/fabric/msp/sampleconfig/signcerts: no such file or directory, err /etc/hyperledger/fabric/msp/sampleconfig/signcerts

Recommendations and Comparisons
Hi, I am a student implementing a Blockchain POC for an institutue that specializes in Financial and Banking Technology. I have primarily worked with Multichain and IBM Fabric till date and am interested in trying out Azure's solution. Do you have any recommendations or comparison charts that I can use to select a solution to start with [I intend to create a small PoC]?
