Jolt · Part 1
Last weekend, we had a blast crafting challenges for a CTF event at the MOCA Italian hacker camp. One cryptography challenge, "2+2=5," involved the Jolt zkVM and a RISC-V program. In this post, we share the ins and outs of the challenge, the clever use of a modified Jolt library, and how we managed to prove an invalid execution without triggering verification alarms. Get ready to dive into the world of Jolt and pick up some nifty insights on exploiting cryptographic systems like a true hacker.
