The next step would be storing the results in a SQL database as we do with our production servers that maintain a queryable database of Open Publish registrations and transactions (Open Publish uses Blockcast for storing metadata on digital media assets). https://github.com/blockai/openpublish-state https://github.com/blockai/openpublish-state This is definitely a more piecemeal approach to creating smart contract applications than with Ethereum's one-stop-shop, but there are benefits to building on top of Bitcoin, especially for Open Publish, which uses native Bitcoin transactions for payments and royalties.
