gno.land - /r/moul/x/vm/bfdemo/v0

Overview

Package bfdemo is the playground for the guest-VM work: a realm that runs Brainfuck programs on chain, a slice at a time.

It is a demo of two libraries and carries no logic of its own: p/moul/x/vm/bf(/p/moul/x/vm/bf/v0) is the machine, and p/moul/x/vm/vmkit(/p/moul/x/vm/vmkit/v0) is the host ABI, the fuel meter and the instance store.

What it exists to show is the thing gno realm code cannot do for itself: a program that runs out of fuel does not fail, it pauses. The realm keeps the snapshot, and the next caller pays for the next slice. Upload a program, call Step a few times, and watch one computation finish across several transactions.

Function
