Nexus Network : Grant Proposal

Nexus Network


The rollup-centric roadmap of Ethereum is resulting in the advent of both general purpose and application specific rollups. The rollups use ETH as gas fees and a critical component of economics resulting in the locking of ETH in the native rollup bridges. As of today, 2.1 Mn+ ETH (USD 4.4 Bn+ in value) is locked in these bridge contracts and the number is only expected to rise going forward.

The Problem

A large supply of ETH is locked in the bridge contracts for rollups. This ETH is not being used for staking which is the central pillar of PoS Ethereum architecture. Staking ETH is the safest way to deploy assets and results in real, sustainable returns while securing the Ethereum network. This can become a big challenge for Ethereum security as more and more ETH gets locked in the rollup bridges

Key Stakeholders Affected

Ethereum network

Ethereum requires a large, active, and reliable validator set to ensure the security of the network. Locking of ETH in Layer 2 bridges can become a significant drag on the security of the network. The network is also facing a challenge of node operator centralisation, from both centralized staking pools run by large exchanges and large liquid staking products with centralized node operators.

Layer 2s

Layer 2s do not have an inherent revenue model to bootstrap their operations and rely on funding/governance tokens. This can lead to challenges for the long-term sustainability of the rollup. Revenue from charging transaction fees on the Layer 2 is expected to decrease over time as the rollup market becomes more competitive with the launch of new optimistic and zk-rollups

The Product

Nexus Network: “Economic Layer for Rollups”

Nexus Network envisions becoming the economic layer for rollups. Using our pluggable staking infrastructure, rollups can earn revenue from the idle assets locked in the bridge contract on Layer 1. Rollups can stake the ETH locked in their bridges within minutes and earn a continuous stream of stable staking returns. Nexus Network leverages Distributed Validator Technology (DVT) and Distributed Key Generation (DKG) for staking. DVT minimizes validator centralization and slashing risks and DKG ensures no single entity owns the complete validator key, hence enhancing security.

Nexus Network has started working with ETH but also has a similar solution ready for DAI that can leverage the sDAi contract by Maker DAO to earn stable yields.

The solution is completely non-custodial with Nexus Network never getting access to rollup ETH or DAI. Other important features include -

  1. Pluggable staking infrastructure - Rollups can integrate with Nexus Network by making small changes in their bridge contract

  2. Customisable staking limits - Rollups can stake anywhere between 0-100% of ETH locked in their bridge to Nexus Network which can be changed in one smart contract call

3, One stop validator management - Nexus Network takes care of validator selection and monitoring and does not put any additional responsibility on the rollup team
