OP_NET aims to enable programmability and smart contract functionality on the native Bitcoin chain.
When Litepaper was released, concerns were raised about Bitcoin L1 becoming congested as builders and users arrived; a scaling solution was needed to support growth.
Fractal was created to allow scaling Bitcoin without changing the core principles of Bitcoin. It is not focused on introducing programmability per se, it requires teams to integrate or build new solutions.
OP_NET is a meta-protocol that exists on top of the blockchain, so it is not limited to running on the native Bitcoin blockchain and can be integrated on other chains.
For OP_NET users, Fractal can be thought of as Optimism or Arbitrum on Bitcoin.
This is a perfect combination, introducing smart contract functionality on Fractal, which can improve speed, efficiency, and low transaction costs; all of which have been proven on native Bitcoin.
