ultra sound relay enhances the decentralization and security of the Ethereum network by enforcing proposer-builder separation, ensuring all proposers have equal access to MEV rewards. This prevents larger proposers from earning disproportionately more than others, which could incentivize validators to consolidate their stake with more profitable entities—a centralizing force. By maintaining an even playing field for all validators, Ultra Sound Relay discourages stake centralization and strengthens the network’s overall resilience and security.
