Wonderboom Signature Aggregation — Ethereum Networking Privacy Map

Description

A high-performance aggregation protocol that utilizes deep aggregation trees and Proposer-Validator Separation (PVS). It mandated physical isolation of proposer processes to obfuscate their gossip footprint, while using direct P2P channels for million-scale signature aggregation.

Relationships

Target	Type	Note
P3	benefits	PVS severs the link between the high-value proposer role and high-frequency voting IP.
P9	benefits	Largest + Random forwarding rule provides mathematical guarantees against deterministic censorship.
P1	benefits	Enables two-slot finality by solving the million-scale aggregation bottleneck.
P7	hurts	Requires significant structural changes to the validator client and network topology.
A12	alternative	Wonderboom uses PVS and direct P2P to bypass the latency of gossip-based anonymity protocols like Dandelion++ for voting.

Open questions
