Hello, for the Vienna Hyperledger Meetup I’ve put together a talk titled “Contract Scripting for Everyone: (Hyperledger) FabCar Registration Sample - From Go Lang Chaincode to (Secure) Ruby Contract Scripts” that shows that - surprise, surprise - (secure) ruby works great for (contract) scripting. Code is code and Hyperledger Fabric is really just a key-value store, that is, a simple hash table. Yes, we are still waiting for the SQL (relational) revolution in the blockchain world. PS: Bonus slides - Do you need a blockchain? TL;DR Version - No.
