## Current Programs

* Helloworld: logs a static string using the `sol_log_` syscall

difference is that the Assembly version *doesn't* set the return code to 0, and
lets the VM assume it worked.

* Transfer-Lamports: moves lamports from a source account to a destination, with
the amount given by a little-endian u64 in instruction data.

be hyper-optimized. The pinocchio version performs very closely to the assembly
implementation!

* CPI: allocates a PDA given by the seed "You pass butter" and a bump seed in
the instruction data. This requires a call to `create_program_address` to check
the address and `invoke_signed` to CPI to the system program.

we can subtract 2500 CUs from each program to see the actual cost of the program
logic.

* Token: a reduced instruction set from SPL-Token. Includes an entrypoint,
instruction deserialization, and account serde. The Rust version is the full SPL
