Ever wondered what Bitcoin with native assets and permissions might look like? If so, check out this short demo of Multichain (a fork of Bitcoin-Core).
MultiChain is backwards compatible with Bitcoin’s JSON-RPC API, so you can easily port your existing Bitcoin applications to MultiChain – and potentially target an enterprise market.
Grab a coffee, check out the white paper and then start hacking on your own private blockchain system. There’s plenty of developer documentation and if you need technical support, post your questions to the official Q&A forum.
