Bitcoin Gets Its Own “Rollups”? KIP-31 Introduces Drivechain-Based Subnets with Ordinal Permissioning

I found an article about this:

While Ethereum has been leading the charge with rollups and modular scaling, a recent proposal is aiming to bring similar programmability and scale to Bitcoin — in a very Bitcoin-native way.

Introducing KIP-31, a proposal from the Koii Network that introduces:

???? Bitcoin-backed rollups via drivechain anchoring

???? Subnet permissioning using Bitcoin ordinals

???? A fork of a Solana-style high-throughput chain to handle smart contracts and execution

Instead of pushing smart contracts onto Bitcoin directly, this design uses a rollup architecture where state commitments anchor to Bitcoin, and subnet access is managed via ordinal inscriptions (yes, like NFTs — but functional).

This raises a few big questions for us as Ethereum folks:

- Can Bitcoin evolve toward programmability without breaking its conservative consensus model?

- Is ordinal-based permissioning an interesting governance primitive, or just a workaround?

- Could this lead to real Bitcoin-native DeFi and NFTs, or is this simply replicating what Ethereum has already solved?

Medium article for context (non-shill, technical tone):

Curious how the Ethereum community views on this.
