The Ethereum ecosystem is built on self-sovereignty and decentralization. This has driven a lot of investment in running L1 nodes and making node operations accessible from home. But that’s only the beginning.

The ideals of Ethereum have extended to many complementary and side projects, fostering a dynamic landscape packed with opportunities for operators. Specialized services are just increasing the opportunities: proving, relaying, sequencing, storing, etc. Modularity in the space unlocks new niches and income streams for those who believe in a cypherpunk future.

From L1 Sidecars to ZK proving and Actively Validated Services (AVS), operators around the globe are finding more and more ways to contribute and be rewarded within the Ethereum ecosystem.

This report snapshots today’s landscape of what's doable today using Ethereum-grade hardware, and where we see things headed next. Following posts will look into dynamics across the Ethereum ecosystem

What sets Ethereum apart from other blockchains is that participation isn't limited to enterprise-scale entities; Ethereum it's designed to be accessible to individuals.

This report categorizes opportunities for two primary profiles: the Home Operator, a user leveraging accessible, consumer-grade hardware for solo participation, and the Institutional Operator, representing professional teams that manage dedicated infrastructure and significant capital to provide services at scale.

Validator hardware on Ethereum, typically a 4-core CPU, 32GB RAM, fast SSD and residential internet connection, gives you access to take part in a network that settles billions of dollars every day.

But those specs aren’t particularly high nowadays, it would take ages to render a complex animation in Adobe After Effects there. How far can this setup take you today?

Naturally, home operators can run Ethereum validators through staking protocols like Lido or RocketPool. These marketplaces match capital providers with node operators, so the hardware requirements remain the same, except for some that have tried new things, like Puffer Finance introducing Trusted Execution Enviroments and Execution Tickets to their operators.

However, many of these protocols play with design and incentives to allow operators to join their protocol with significantly less than the standard 32 ETH stake with usually better returns when compared to vanilla staking. At the time of writing, Lido CSM offers the lowest entry point with the bond for validators going as low as 1.3 ETH.

Home operators can also add out-of-protocol services to their pair of Mainnet clients. The most popular one is obviously MEV-Boost, giving you access to the market of block builders through trusted relays, but there’s relatively new sidecars coming up like Commit-Boost, a modular sidecar that enables validators to manage proposer commitments, including pre-confirmations and inclusion lists.

The biggest L2s (Base, Arbitrum One, ZKsync…) still rely on centralized sequencers operated by their core teams or by enterprise-level entities. Full decentralization has remained a roadmap promise.

In the ongoing pursuit of decentralization and censorship resistance, new solutions come into the light. For instance, Aztec is the only L2 that’s strongly pushing for permissionless sequencing, with operator roles already available on its public testnet! Espresso Network with it’s Mainnet 0 live provides L2s with a decentralized confirmation layer, improving security and cross-chain interoperability.

Restaking and Actively Validated Services (AVSs) are rapidly opening new opportunities by leveraging Ethereum's security. EigenCloud is a clear example: any Ethereum address can register as an operator, needing only to attract delegation from other restakers or by self-delegating.

Within Eigen's sphere alone, data shows over $12B from restakers and +160 AVSs in development, while other platforms like Symbiotic are also growing. Restakers help to secure a diverse range of services, ranging from DA verification and message relaying to offchain oracle data and ZK coprocessing. For example:

• EigenCloud is Eigen’s new platform designed to deliver verifiability-as-a-service for any app, on or off-chain. It unifies the AVS ecosystem with core primitives like EigenDA, EigenVerify and EigenCompute to bring complex off-chain tasks into a verifiable, crypto-secured enviroment.

• Lagrange, operating its ZK prover network as an AVS on mainnet, supports light client and state verification services. While its participation is accessible, running a Lagrange node effectively typically requires a minimum of 8 cores (16 threads), and 40+ GB of RAM, ideally on a dedicated instance.

• Witness Chain provides proof-of-location services and is already live on EigenLayer.

Some categories of the AVS easier to run for home operators:

Protocols like The Graph and Hyperlane enable solo operators to run indexers or message relayers. Hyperlane's AVS on EigenLayer, enhances its interoperability protocol with economic security; operators can validate outbound messages, with rewards anticipated soon.

While running a basic node for indexers like The Graph is possible with modest hardware, becoming a indexer on its network (requiring ~100k GRT, or ~$9.8k as of May 2025) is a capital-intensive role.

While full ZK proving typically demands high-end GPUs (>24GB VRAM), lighter-weight proving roles are emerging. Projects like Taiko (a zkEVM with CUDA GPU support) are opening up proving roles that will become permissionless over time. Several projects show potential for operators with varying setups:

For AI, Ava Protocol, an AVS for autonomous on-chain tasks, shows potential for operator participation with moderate requirements in it’s testnet.

Institutional Operators run infrastructure as a business, often with dedicated teams, data center access, and significant capital. These advanced setups are essential for providing the high-uptime, critical services that the ecosystem most demanding apps rely on.

So, beyond the roles accessible to a home operator, what new tier of high-throughput and specialized services does this level of operation unlock?

Some AVSs offer higher yields for heavier workloads (e.g., heavy DA loads, ZK proving). These may demand custom infrastructure, dedicated nodes, or larger stake commitments.

For instance, Aligned Layer, a ZK proof verification AVS, requires robust hardware (e.g., 16 CPU cores, 32GB RAM) and is whitelisted for its testnet. Similarly, participation in ARPA Network is also currently whitelisted, while other advanced roles, like in Lagrange’s ZK stack, are permissionless but demand superior compute resources.

Protocols like EigenDA, and Celestia are crucial for the scaling of the internet of value. Operating a DA node for these networks typically requires significant throughput and storage capacity, rewarding those who can reliably serve and verify large datasets.

For EigenDA, operation is permissioned by capital: entry is limited to the top 200 operators by delegation.

The operator market is continually evolving, driven by the shift towards modular infrastructure, the growth of AVSs, and the integration of advanced cryptographic and AI technologies. This evolving landscape offers a spectrum of opportunities: from accessible entry points for home operators (particularly within the AVS ecosystem) to more resource-intensive services for institutional operators, with new roles anticipated in areas such as:

Proving-as-a-Service ZK protocols (Scroll, zkSync, Starknet) will outsource proving to third parties in the future, but this will require operators with significant GPU compute power.

Verifiable AI + Coprocessing The integration of AI into blockchain infra is creating opportunities for operators to provide verifiable AI computations. By leveraging TEEs and specialized hardware, operators can contribute to secure and decentralized AI processing networks like Lagrange.

Data Availability Services The proliferation of L2 solutions increases the demand for robust DA services. Operators can capitalize on this trend by running DA nodes, contributing to the scalability and reliability of rollup ecosystems.

Modular MEV Infrastructure The evolution of MEV infrastructure towards modular architectures allows a broader range of operators to engage in MEV-related activities. By adopting modular tools and frameworks, operators can participate in MEV extraction without the need for extensive infrastructure. Block building networks focused on MEV, such as Buildernet, are shaping this space, often leveraging TEEs with early access available for high-performance setups

These areas will be explored in greater detail in following reports.
