proofs
how a block proves itself, quantum-proof.
every block carries a ML-DSA-87 signature over its header and a zk-STARK proof over its execution. verify the signature and you know the block is authentic; verify the proof and you know it executed correctly.
you don't trust a validator. you verify a signature that no quantum computer can forge, and a proof that no amount of compute can fake.
that's the whole idea: Lattice is a chain you can check, not a chain you have to believe.
