Minimized Trust Assumptions

By allowing users to invoke programs with a native Bitcoin transaction, Arch improves the user experience, by reducing the number of steps needed to interact with the platform, and reduces security risk, since there is no bridge implementation to depend on.

Arch users put trust in the decentralized key generation scheme for assets, only while their assets are controlled by Arch-network Bitcoin addresses, and also for the consistency of external-to-Bitcoin state. Users also place trust in the program authors, the same as with other smart-contract type networks.
