Hello Chris! With regards to your question on official casino licenses for on-chain gambling smart contract, I point you to a post by the Edgeless team at => https://www.edgeless.io/blog/license-received-edgeless-becomes-first-legal-blockchain-casino which appears to be a license also granted by Curacao (similar to the EOSBet license?). It is easy to find other articles on the Edgeless license with a quick Google search (it was also promoted as "The One And Only First Ever Blockchain Gambling License) but the Edgeless team no longer seem to be boasting about it on their main page...
