Crate sp1_lib

System calls for the SP1 zkVM.

Modules

• io
• unconstrained
• utils

Macros

• unconstrained
  Executes a block of code unconstrained by the VM. This macro is useful for running code that helps provide information to the program but does not need to be constrained by the VM. For example, running ecrecover is expensive in the VM but verifying a signature when you know the public key is not. unconstrained can be used to provide the public key without spending VM CPU cycles.
