Most chains slow down because every action touches the same shared state.

Update one account, and the whole system has to stay in sync.
That’s why high-traffic apps create lag everywhere else.

@0xMiden's Notes model avoids that completely.

A Note is its own piece of state.
It stands alone.
When it changes, the network only verifies that change; not your entire account, not the global tree, not every variable tied to your history.

That single design choice removes most of the overhead people think is “normal” in smart contract systems.

Here’s the simple version:

• Accounts = one big bucket
• UTXO = many tiny buckets but hard to combine
• Notes = many tiny buckets you can combine

Miden takes the isolation strength of UTXO and the flexibility of accounts, and merges them into something that scales without breaking UX.

Because each note is private by default and each transition is proved locally, you get:

• fast verification
• built-in privacy
• predictable execution
• less competition for global state

And since Notes can link or reference each other, you don’t lose composability.
Apps can still build complex flows, they just don’t force the whole chain to update with them.

This is why the Notes model matters:
it fixes the part of blockchain design that usually becomes a bottleneck as soon as real usage arrives.

Small pieces of state scale better than one giant account.
@0xMiden builds around that idea.
