"Quite honestly, I don't think we should be doing smart contracts on Bitcoin. Bitcoin doesn't do smart contracts, and it doesn't do smart contracts because it does security." - Andreas Antonopoulos

Taken from [LTB #414 Live Q&A](https://letstalkbitcoin.com/blog/post/ltb-414-lets-talk-bitcoin-live-qa) *Stephanie Murphy: “What's everybody's view on Rootstock (RSK)?”* Andreas M. Antonopoulos: I don't think Rootstock is putting smart contracts on Bitcoin. Rootstock is allowing you to use Bitcoin to pay for smart contracts on the Rootstock Drivechain, which you could theoretically do by shifting money into Ethereum. In fact, recently I saw someone who had built a gateway that allowed you to make a Lightning payment that terminated in an Ethereum contract. So there's many ways to bridge different blockchains together. Quite honestly, I don't think we should be doing smart contracts on Bitcoin. Bitcoin doesn't do smart contracts, and it doesn't do smart contracts because it does security. That's not a trade off I think is worth doing. It's much better to leave that to a chain that has a much more experimental culture and can take bigger risks. As to whether we can do smart contracts, that's not a binary question; it's a question of value. So can we do smart contracts that can keep $1,000,000 secure? Yes. $10,000,000? Maybe. $100,000,000? No, the DAO proved that. How about now? DAI is doing more, so maybe yes. So it's basically a moving front. As the the maturity of the smart contract ecosystem expands, we can do bigger and bigger stakes (no pun intended) within the smart contract ecosystem. Every now and then there's gonna be a fairly catastrophic failure that's gonna cause a regression in the amounts of money that's put in them. But essentially it's growing. We're proving this every day, and it's the same thing with Bitcoin. The way you measure security in a smart contract or you measure security in a cryptocurrency like Bitcoin is how secure is Bitcoin? X billion dollars. That's the stake that is sitting on it right now, unhacked so far. **BONUS: Bitcoin's security model as block reward approaches 0.** *Stephanie Murphy: “Do you think Bitcoin will be able to ...
