Author: <a target="_blank" rel="noopener noreferrer" href="https://bloxroute.com/">bloXroute</a> Nearly eighteen months into the Proof-of-Stake era initiated by the Merge, the essence of staking has crystallized, leading us into a period where optimizing performance, security, and scalability for mass adoption takes center stage. In pursuit of refining validator performance, a variety of tools and strategies have been developed, with timing games emerging as a significant area of focus. Navigating this complex environment demands from validators not only technical acumen but also a keen strategic sense, as optimization intertwines technical know-how with competitive tactics.In response to these complex challenges, bloXroute has introduced the Validator Gateway, an innovative tool aimed at boosting APY and enhancing validator effectiveness significantly. This tool, consisting of the Relay-Proxy and BDN Gateway, is designed to minimize the latency between validator nodes and MEV relays by utilizing more effective getHeader and getPayload mechanisms during block proposal. These mechanics are key in preventing missed slots and provide validators with greater control over timing parameters critical for maximizing rewards. When combined with bloXroute’s leading blockchain data acceleration infrastructure, the Blockchain Distribution Network (BDN), it ensures faster block and transaction propagation, thus enhancing node synchronization.Data reviewed on initial usage points to substantial improvements, with a noticeable increase in APY rewards by at least 5% and an enhancement in validator effectiveness of up to 1.5%. Of the over 19,000 active validators utilizing the Validator Gateway, usage data indicates a 6% increase in blocks won via the Relay-Proxy. This represents a significant leap forward, providing those involved in block creation with a competitive advantage within the dynamic Ethereum ecosystem. The Validator Gateway has gained traction among prominent figures in the blockchain space, illustrating its widespread utility and appeal. Early adopters like HashKey Cloud, InfStones, and Bitcoin Suisse, along with collaborations with Figment and Blockdaemon, underscore its essential role in meeting the Ethereum community's infrastructure needs.&nbsp;<h2>Under the Hood of Validator Performance</h2>Understanding the nuances of validator performance is a key factor in ensuring high performance. Ethereum validators earn rewards through attestations, proposals, and sync committee signatures, each critical for maintaining the blockchain's accuracy and security. Yet, the distribution of rewards is uneven, introducing reward variance due to factors like the total number of validators and the randomness of selection processes.Platforms such as rated.network track effectiveness ratings, which are key to evaluating validator performance. A slight difference in these ratings can indicate significant disparities in performance. For example, a 94% rating might be seen as lacking, whereas 97% is exemplary, underscoring the competitiveness of validator operations. Achieving a perfect score is nearly impossible, as no validator can consistently hit a 100% effectiveness rating.<img src="https://tidy-ball-c49dc59f59.media.strapiapp.com/validator_effectiveness_rating_360db68cc9.jpg" alt="validator-effectiveness-rating.jpg">Source: Rated.NetworkVarious factors contribute to this challenge, including latency, distance from relay points, or misalignment with the network's current state. The Validator Gateway specifically targets these issues, ensuring low latency connections and optimal ‘getHeader’ and ‘getPayload’ data flow between bloXroute relays and validators.&nbsp;<h2>Validator Gateway Components</h2>To effectively manage the intricacies of reward variability and improve validator effectiveness, innovative solutions are imperative for enhancing validators' operational performance and maximizing their rewards. The Validator Gateway introduces critical innovations through its two main components: the Relay-Proxy and the BDN Gateway.Relay-Proxy: Employing a gRPC connection with bloXroute relays, the Relay-Proxy facilitates a range of operations, from initial registration to managing 'getHeader' and 'getPayload' commands. This connection dramatically reduces the latency between relays and validators, ensuring validators have timely access to the most lucrative headers during the proposal of slots. Optimized for compatibility with MEV-boost or vouch clients, the Relay-Proxy effectively functions as another relay.<img src="https://tidy-ball-c49dc59f59.media.strapiapp.com/mev_relay_5df353241d.jpg" alt="mev-relay.jpg">Distinct from the conventional method, where a validator would query each connected MEV relay individually per slot, often leading to missed opportunities for maximum rewards, the Relay-Proxy enhances this process. By being strategically located near the validator's node and utilizing a swift gRPC connection, it continuously streams headers from MEV relays. This setup guarantees that validators are always presented with the most rewarding headers throughout the slot duration, accommodating the unpredictable nature of when the most valuable header might emerge. The integration of this sophisticated, quick delivery system for headers, alongside the Relay-Proxy's customizable slot timing, markedly increases APY through improved performance in block proposals. It equips validators and node operators with the means to fully utilize their designated proposal windows, greatly diminishing the likelihood of missed slots and maximizing chances for rewards. Crafted for easy integration, the Relay-Proxy is an essential conduit to mev-boost or vouch clients, necessitating no further alterations while satisfying all critical network demands.BDN Gateway: The BDN Gateway, working in tandem with the Relay-Proxy, harnesses the power of bloXroute's Blockchain Distribution Network (BDN). Renowned for its role in enhancing efficiency and performance across the MEV and DeFi landscapes, the BDN has been a reliable force for more than half a decade. It specializes in the rapid dissemination of blockchain data through various channels, ensuring validators are consistently aligned with the latest network state, thereby avoiding the lag that could affect their performance and the potential for earnings.By incorporating the BDN Gateway into the Validator Gateway's architecture, validators gain a distinct edge. This component accelerates the propagation of blocks and ensures more synchronized network engagement, crucial aspects that drive a validator’s operational success and the likelihood of increased rewards. The BDN Gateway's ability to propagate blocks and consensus information faster across the network significantly reduces the effects of reward variance, providing a more dependable and consistent performance outlook for validators.Utilizing a gRPC connection with the Relay-Proxy alongside the BDN's capabilities to hasten the proposal process not only minimizes the occurrence of missed opportunities but also secures for validators the timely access of profitable headers. This advantage bolsters their prospects for successful block proposals. With the Validator Gateway enhancing effectiveness metrics by 0.5% to 1.5%, it offers a vital lift in performance that could notably affect validators' rewards. In a context where even minimal improvements in effectiveness can lead to substantial gains in APY, this advancement proves to be meaningful for validators.&nbsp;<h2>Looking Forward</h2>The Validator Gateway is gearing up for an array of enhancements and new functionalities designed to further refine validator operations. A key objective in this development journey is to boost the APY increment to an ambitious 10% or beyond, showcasing bloXroute's zeal for expanding the limits of validator productivity and financial returns. The introduction of a Self-Hosted Gateway feature is a pivotal step towards this goal, offering validators unparalleled flexibility to customize the system according to their unique requirements. This feature, together with a suite of forthcoming innovations, highlights bloXroute’s commitment to serving a diverse array of operational needs and solidifies its dedication to continual innovation and progress within the blockchain sphere. In addition, bloXroute is actively collaborating with Lido to simplify the Validator Gateway integration process for validators and node operators, ensuring a smooth adaptation for diverse configurations.Setting up the Validator Gateway has been made remarkably straightforward. Beginning with a bloXroute account registration, the initial configuration requires incorporating the Relay-Proxy as an additional relay within the mev-boost -relays argument. Following this, a form completion step enables the bloXroute team to provide the necessary Peer ID, facilitating the Validator Gateway's connection to the Consensus Layer as a trusted peer.
