I wrote [RFC #33 Kusama Network 2.0: The Hybrid Chain Network](https://github.com/polkadot-fellows/RFCs/pull/33), asking that we add Smart Contracts on the Relay Chain, elevating Kusama to the level of Ethereum.  This is contrast to Polkadot being a [RFC #32 Minimal Relay Chain](https://github.com/polkadot-fellows/RFCs/pull/32).

By adding Smart Contracts to the Kusama Relay Chain, developers can scale from sync-first "old" blockchain technology to "new" in this spectrum:

1. full sync patterns in Smart Contracts on the Relay Chain. _This pattern is manifested in Ethereum but has never been seen in Polkadot or Kusama._
2. full sync patterns in Smart Contracts on a Parachain. _This pattern is seen in Astar + Moonbeam._
3. full sync patterns in Substrate pallets on a Parachain. _This pattern is seen in all other parachains._
4. hybrid sync + async patterns in Smart Contracts on a Relay Chain. _This pattern is manifested in Ethereum with Axelar/LayerZero._
5. hybrid sync + async patterns in CoreJam + CorePlay. _This pattern is under active development and will appear in Kusama 2.0 + Polkadot 2.0._
6. hybrid sync + async patterns in Substrate Pallets. _This pattern is seen in all other parachains._

Developers can _start_ at any point in the above spectrum and move upwards as their needs for scale increase, culminating in CoreJam/CorePlay and Substrate pallets in app chains. Polkadot 2.0, in contrast, can be a Minimal Relay Chain (#32) for maximal scalability.

This proposes to turn on 1+4 by adding `ethereum` and `contracts` pallets and basically having Kusama adopt both Ethereum + Polkadot's roadmap to scalability.

If this makes sense, then we can develop [Optimism on Kusama](https://github.com/colorfulnotion/optimism/blob/develop/README.md), which would have users+devs bringing in KSM as a core solution.  

Shall we bring EVM Contracts to Kusama Relay Chain and increase KSM Revenues?

- The author wants to add Smart Contracts to the Kusama Relay Chain.
- This will make Kusama similar to Ethereum in terms of functionality.
- There are different patterns for implementing Smart Contracts on different chains.
- Developers can start at any point in the spectrum and move upwards as they need more scalability.
- The proposal suggests adding Ethereum and Contracts pallets to Kusama and following both Ethereum and Polkadot's roadmap for scalability.
