Following up on my earlier post here about DSM, the beta is now open.

DSM is a deterministic state machine: a new primitive for building applications without a global public ledger, with Bitcoin integrated as a native built-in asset.

A few design points, stated plainly:

- There is no global ledger.
- There is no intermediary.
- There is no global witness set.
- Ordering is relationship-local, enforced by hash adjacency and state progression rather than timestamps, block production, or a global sequencer.
- Inside DSM, transactions are feeless. There are no DSM transaction fees. You only pay normal Bitcoin network fees when value enters or exits Bitcoin custody.
- DSM supports offline bilateral transfers with instant finality inside DSM once the valid state advance occurs.

This beta is running on Bitcoin Signet, and it is now at the point where people can actually try it.

This project was built mostly under wraps until now, without any real public push or community-building effort. The beta is the point where I am opening it up.

Critical feedback on the security model and design assumptions is welcome.
