This paper introduces a proposal for a Proof Carrying Code (PCC) architecture called Lissom. Started as a challenge for final year Computing students, Lissom was thought as a mean to prove to a sceptic community, and in particular to students, that f
ormal verification tools can be put to practice in a realistic environment, and be used to solve complex and concrete problems. The attractiveness of the problems that PCC addresses has already brought students to show interest in this project.
