The smart contracts are currently deployed to 6 EVM chains (Ethereum, Moonbeam, Moonriver, Celo, Unique, Quartz) and I think it could potentially really add traction to the mass adoption of Bitcoin
Explain me how. What need does these smart contracts satisfy to help on achieving global adoption? None, as far as anyone can tell. Mass adoption is rather not happening due to responsibility issues, misinformation and not really big need for bitcoin.
if we can support it, however, I am not sure if it is even possible. Any technical advise and guidance would be appreciated.
It is technically possible with sidechain. The one with the most development is RGB that is mentioned above.
And then, you can have this N-of-N "everyone agrees" signature as a base for any Turing-complete contract you want.
Can you give us an example?
