Nope, this wouldn’t do anything, but only tangentially because of snark workers. The reason is that its tamper proof due to Mina’s ZKP, and so changing it at any time would be detectable in the archive node. Trying to tamper with the past also wouldn’t affect the current state at all, which is also backed by the ZKP and so can’t be modified undetectably

Hi Hector, it would be best to ask these types of questions on our Discord server #archive-nodes channel 🙂
