Polygon (MATIC), a layer-two network designed for scaling and
application infrastructure development on Ethereum (ETH)...

Any coin that depends on and runs on top of a network
that is itself nonscalable... is therefore also not scalable.

Ethereum does not scale because, like nearly all other coins,
it requires an amount of physical storage space that grows
without bound over time to store all the transactions. This
blows out individual repos thus depending users on non-private
sharding lookup schemes, over realtime non-private analyzable internets,
into massive storage clouds holding lifetimes of privacy break risks,
and that don't need to exist in the first place. Etc.

ZKP DAG etc can help create coins whose physical growth
is counted by endless transactions, but to limited addresses,
a far smaller number, made further smaller due to privacy.

Look into making using and adopting a new class of
necessarily sans-tx-storage privacy coins.

The future belongs to... privacy, sans-tx-storage, crosscoin DEX.

Invent the future.
