The issue of status is the long-term cost of the chain.

@0xMiden did not continue to optimize "how to write global state faster," but directly changed the model.
Actor.

In Miden VM, each account only modifies its own state.
Not shared, not mutually written.
Without global writes, there are no lock contention.

Parallelism is not squeezed out by scheduling; it is structurally established by default.

The change brought about is not just in performance, but in the complexity of the state being localized.
The behavior of one account no longer implicitly affects the entire chain.

You can understand it as:
Microservices architecture in blockchain.

While most chains are still patching up state bloat, Miden chooses to cut into the state itself from the root.
