With Bitcoin's immense dominance and unmatched market cap, imagine if DeFi was fully built on Bitcoin Layer 1, but with:

- Full composability (no bridges or wrappers needed)

- High scalability

- Full smart contract support

- Rollback options for critical events

If such a system became reality, would developers and builders flock back to Bitcoin, given its strong adoption and network effect?

And if that shift happens—what would become of Ethereum, Solana, and other DeFi-native chains that have long been the playground for innovation? Would they become obsolete, or would they evolve to remain relevant?
