| ## Abstract | ||
|
|
||
| Lean Ethereum replaces the beacon chain's BLS signatures with post-quantum, hash-based signatures, which are individually larger than BLS signatures and, unlike BLS, cannot be cheaply combined by adding the signatures themselves. Lean consensus therefore performs attestation aggregation by generating a succinct cryptographic proof that the post-quantum signatures attached to many validator attestations are valid, using a specialized minimal virtual machine. Producing such proofs is far more computationally expensive than the elliptic-curve addition used to aggregate BLS signatures, so the `L*` beacon-chain hard fork separates aggregation from block production and assigns it to an opt-in, higher-specification participant: the *aggregator*. Any node may opt in as an aggregator if it has the hardware to support proving on the slot's critical path. This EIP specifies the aggregator role introduced by the `L*` hard fork; the authoritative definitions of the signature scheme, proof system, wire formats, and consensus rules live in the lean consensus specification (leanSpec). |

remove lean and make it Post Quantum (PQ) , similarly everywhere else

| ### Fast finality multiplies the number of attestations | ||
|
|
||
| Lean consensus targets fast finality (3-slot finality, trending toward single-slot finality) with short, 4-second slots. Where today's chain spreads voting across an epoch and finalizes in roughly fifteen minutes, fast finality effectively requires a large fraction of the validator set to sign attestations every slot and to have those votes counted within the slot. The number of signed attestations that must be transported per slot therefore grows by orders of magnitude relative to today. |

don't mix fast finality or anything else into the mix, make it an independent proposal

I cannot find an option to create a new topic, do I need a special role/ permission to do that?

describe how aggregators perform attestation aggregation by collecting signed validator attestations and proving the attached post-quantum signatures into succinct aggregate proofs.
