In general, Moonbeam makes it a lot easier to build applications on Polkadot blockchain compared to implementing a full parachain or parathread. Specifically:
- Substrate is powerful but complex. With a Moonbeam-based application, you don’t need to worry about token economic models, issuance schedules, governance, incentivizing nodes, or security — all of which are required when launching your own blockchain.
- You can leverage Moonbeam’s full connection to the Polkadot Relay Chain, which the Moonbeam economic model pays for on an ongoing basis. This is much less expensive than paying for parachain- or parathread-based access on your own.
- You will have a smooth upgrade path from a Moonbeam smart contract/DApp to becoming a full parachain or parathread (if and when you need the scalability and full control that comes with running your own blockchain).
