I'm new to Stellar and this community. I want to create a decentralized network for information sharing. Essentially a distributed database with data validation using blockchain. I have looked into Hyperledger Fabric before for such a task but deemed SCP to be more fitting for my needs.
My question is, could I use Stellar-Core for such a task? Namely, is creating a completely separate private network with custom data types possible? All of the information out there I found talks about private networks in terms of financial transactions and account registrations with the (private) network, which makes me think that financial transactions are built-in/intrinsic to Stellar-Core. If not, how can I create this network for such far-fetched purpose? And what is the difference between Stellar-Core and Stellar SDK?
