In my opinion a Layer-2 and/or sidechain implementation will bring EVM/WASM compatibility for NoM and will greatly expand the ecosystem. The NoM Multichain Technology can become a de-facto hub for interoperability within the ecosystem. This way, the base layer remains minimal & efficient as Mr Kaine emphasizes and all the heavy work/bloat is kept in a separate execution domain. Pillars produce inflation as `ZNN` and they will also run the `orchestrator` nodes. It makes sense for them to also act as validators for a L2/sidechain where fees are paid in `ZNN`. The L2/sidechain should not produce additional/separate inflation. Pillars can bridge part of their `ZNN` inflation into the L2/sidechain ecosystem and they will be incentivized to bridge more if usage is high. `ZNN` is not a gas token because the L2/sidechain will use a wrapped representation of it. It can be called `eZNN` or `xZNN` (execution ZNN). We can use the decentralized bridge @sumamu built and tweak it to support this type of wrapping. It would be a little bit different from wrapping `ZNN` to `wZNN` and unwrapping it later because `xZNN` will actually be consumed/burnt in the extension chain, so it won’t be a 1:1 backing. `xZNN` can be associated with the gas concept for the extension chain. Since there won’t be any inflation, the extension chain will only have a fee distribution mechanism: - 33% distributed to builders (contract deployers) - 33% distributed to extension chain validators - 34% burned (similar to ETH) --- _[View the full topic](https://forum.hypercore.one/t/extension-chains/52)._
