MPC in the head was one of the more contentious issues of the protocol, serving as a zkp which essentially runs the entire MPC exchange "in the head" of the prover, creating a transcript of the work to sufficiently convince a verifier that the result is correct. For the token application, this is fine, as token interactions are all-or-nothing, so transcripts can be pruned. But a clever attacker could generate extremely laborious proofs to do very little to impact data, but stacks sufficiently that the state growth becomes large enough that it could limit the issuance curve, with a runaway effect if they did it in bulk, making the issuance rate for tokens effectively stop for the current generation.
