Hey 9dorf, thank you for the question, give me the opportunity to clarify that this proposal is for open sourcing the engine.
It is not about providing a service or an infrastructure. This is addressed by @bgeihsgt’s proposal: DFK Community Extended API with whom I look forward to working together on making the service available, powered by the indexer of this proposal.
To be more specific around how this will work, it will be a standalone node.js application. You download it, install the NPM dependencies and configure it according to instructions in the README.
Once you have configured credentials to your database and run the application, it will automatically create the tables and schemas and start operating according to the issued command.
I am also considering providing pre-indexed data, in the form of data dumps so as to get a head-start on indexing and not having to re-index the whole chain from the start.
Hope this answers your question.
