keto smart contracts
The Keto blockchain acts as the protocol layer this is the equivalent of the kernel or system of an operating system. It is responsible for managing the propagation of transactions, and blocks and for managing the consensus of the network. Above this sits the user space or application space much as it does in an operating system.
This is the space that contracts are executed in. Keto relies on this space to execute System level contracts. These contracts are responsible for fee management and other system operations.
This enables a great level of flexibility as the contracts can be upgraded to another version without the need of core protocol changes. This provides a great deal of flexibility.
