https://yellow.com/learn/polkadot-shared-security-model-parachains-explained>How Parachains Submit Proofs Without Trusting Validators Blindly>Polkadot's security model relies on a mechanism called Proof of Validity (PoV). Each parachain has its own block producer, called a collator. Collators gather transactions, produce parachain blocks, and then create a compact proof that summarizes the state transition. Think of this proof as a receipt: it doesn't reproduce the entire computation, but it encodes enough information that a validator can verify the transition was legitimate.>That PoV block is submitted to a small, randomly assigned subset of Relay Chain validators called a parachain validator group. This group checks the proof and, if everything is valid, signals approval. The Relay Chain then includes a record of this approval in its own block, anchoring the parachain's state change to the finalized Relay Chain.>What prevents a validator group from colluding and approving a fraudulent block? Polkadot uses a technique called approval voting as a secondary check.

>>62388395what prevents malicious collators from colluding to submit proofs of parachain transactions that have valid signatures but impossible state changes

Lol I think i threw the algo a curveball here
