Blockchain networks depend on a decentralized web of participants to keep them running smoothly. One of the most critical roles in this web is that of a validator, the entities responsible for confirming transactions, producing blocks, and maintaining consensus on the chain. As more blockchains adopt Proof-of-Stake (PoS) and related systems, validators have become central to the infrastructure that keeps these decentralized systems secure and performant.

In these systems, active validator services have appeared as professional, full-time operators that handle complex technical requirements on behalf of stakers. They provide uptime, reliability, and contribute to the governance and direction of the networks they support.

In this article, we’ll break down what validators do, how active validator services work, and why they’ve become such an important part of today’s blockchains.

What Do Validators Actually Do in a Blockchain?

In any blockchain, consensus is what guarantees that all participants agree on the state of the network, what transactions are valid and which blocks are part of the official chain. Validators play a key role in this process, but their exact duties depend on the consensus mechanism the blockchain uses. Let’s look at three of the most widely adopted consensus models involving validators.

Proof of Stake (PoS)

In traditional PoS systems, validators are selected to propose or attest to blocks based on the number of tokens they have staked (locked) as collateral. The more tokens a validator stakes, the higher the chance of being selected to validate a block and earn rewards. Ethereum is the most prominent PoS blockchain, where validators need to stake 32 ETH to participate directly.

Validators in PoS are financially incentivized to act honestly. If they attempt to manipulate the network, their stake, or a portion of it, can be "slashed" as a penalty. Validators also risk losing rewards if they go offline, fail to validate, or miss important duties.

Delegated Proof of Stake (DPoS)

In DPoS systems, regular users (token holders) elect a smaller group of validators, often called delegates, to represent them. These elected validators are responsible for block production and transaction validation. Voting is often weighted by token holdings.

Blockchains like EOS and TRON use DPoS to increase scalability and reduce the number of validating nodes to a manageable set. While this improves throughput, it can lead to a more centralized validator set. That’s why governance participation and transparency are especially important in DPoS environments.

Nominated Proof of Stake (NPoS)

Used by Polkadot and Kusama, NPoS introduces a layer of trust delegation similar to DPoS but with more randomized and decentralized validator selection. Token holders (called nominators) back validators with their stake. However, instead of electing a fixed group, nominators share responsibility, and risk, with the validators they support.

NPoS attempts to balance decentralization and efficiency by making it harder for a few large actors to dominate validation. If a validator misbehaves, both the validator and their nominators may be slashed, so choosing validators wisely is critical.

What Are Active Validator Services?

Running a validator node is not a trivial task. It involves setting up and maintaining high-performance servers, maintaining constant uptime, managing secure key storage, and staying compliant with the technical standards of each blockchain. This is where active validator services come in.

A Practical Definition

Active validator services are professional entities that operate validator nodes on behalf of others. They maintain 24/7 infrastructure, adhere to strict performance and security requirements, and often participate actively in the governance of the networks they support. These services allow users to delegate their tokens to a trusted operator in exchange for a share of the staking rewards.

Active vs Passive Validators

While anyone can theoretically run a validator node, doing it well requires technical expertise, capital, and continuous oversight. This is the key distinction between active and passive validators.

Passive validators are often individuals or hobbyists who run validators with limited infrastructure and monitoring. They may only validate sporadically, have little to no engagement with the blockchain community, and might not offer any service guarantees. While they may charge lower fees, they often come with higher risks, such as downtime, slashing penalties, or missed rewards.

Active validator services, on the other hand, operate validator nodes with enterprise-level reliability. They have dedicated engineering teams, round-the-clock monitoring, backup systems, and audited security processes. Many are involved in the governance and long-term planning of the protocols they validate, contributing code, writing research, or participating in community discussions. For users, these services offer a more secure and hands-off way to earn rewards from staking.

Why Use an Active Validator Service?

Active validator services offer a range of advantages that go far beyond simple convenience. Their infrastructure and governance participation directly improve both your returns and the overall health of the blockchain network.

Security and Infrastructure Reliability

Validator downtime or poor key management can result in slashing, which means a portion of your staked tokens could be permanently lost. Active validators invest in:

• Multi-location failover systems
• Hardware security modules (HSMs) or multi-signature wallets
• Real-time monitoring and alert systems
• Routine updates to avoid client vulnerabilities

This dramatically reduces the risk of downtime or penalties and warrants maximum validator performance.

Higher Staking Rewards

Because they maintain high uptime and performance, active validators are more likely to participate in more blocks, leading to consistent and often higher staking rewards for their delegators.

Governance Participation

In many blockchains, validators vote on critical decisions such as protocol upgrades, fee structures, and security parameters. Reputable validator services often publish governance reports, explain their voting rationale, and advocate for decentralization and transparency, giving delegators a voice in shaping the future of the network.

Accessibility for Non-Technical Users

Not everyone can run a full node, configure validation clients, and keep them online 24/7. Active validator services make staking accessible for everyone, from individual retail investors to institutional funds, without sacrificing performance or security.

Choosing the Right Active Validator Service

Choosing the right validator is crucial, not just for optimizing rewards, but for protecting your stake and supporting responsible actors in the system.

What to Look For

• Track Record and Transparency: Check the validator’s history. Have they ever been slashed? Do they regularly report their performance and governance decisions?
• Technical Uptime: Networks like Cosmos and Polkadot track uptime scores. Look for validators with near-perfect performance.
• Slashing Protection: Some services offer slashing insurance or advanced risk controls to protect delegators.
• Validator Fees: Validator services take a commission from your staking rewards. Lower isn’t always better, evaluate fees in relation to service quality.
• Multi-chain Support: Validators who operate across multiple networks often have more vigorous processes and better infrastructure.
• Community Engagement: The best validators contribute to the open-source ecosystem and regularly engage with the community.

Notable Active Validator Services

Here’s a closer look at leading validator services and what sets each of them apart:

Lido Finance

Lido is the leading provider of liquid staking, a model that allows users to stake their crypto while retaining liquidity through tokenized staking derivatives (e.g., stETH for Ethereum). Instead of locking up your ETH or SOL, you receive a tradable token that accrues staking rewards.

Lido operates validators across multiple networks through partnerships with high-quality node operators. It is governed by a decentralized autonomous organization (DAO), which votes on validator inclusion, fee structure, and treasury use.

Key strengths:

• Liquid staking model allows DeFi integration;
• DAO governance adds transparency;
• High validator performance across Ethereum, Solana, and others.

Figment

Figment is an enterprise-grade staking service that supports over 30 protocols including Cosmos and NEAR. It caters to institutions and developers, offering staking, node infrastructure, and analytics tools.

Figment is known for:

• Institutional-grade security and slashing protection;
• Real-time analytics and performance dashboards;
• Open governance participation and documentation.

Everstake

Everstake is a community-driven validator service supporting over 50 blockchains. It’s especially active in the Cosmos ecosystem and growing PoS networks like Sui and Aptos.

What stands out about Everstake is:

• Global community outreach, especially in newer markets;
• Transparent operations with open-source tooling;
• Deep integration with blockchain foundations and community grants.

Everstake publishes educational content, runs validator dashboards, and frequently partners with networks to support ecosystem development.

Conclusion

Active validator services are key contributors to the evolution of decentralized networks. By providing infrastructure, governance participation, and secure staking options, they allow both small investors and large institutions to engage with blockchain ecosystems without taking on unnecessary risk.

As staking becomes a default mode of participation in Web3, choosing the right validator will be as important as choosing the right wallet or exchange. Whether you value performance, governance alignment, security, or convenience, there’s likely an active validator service that fits your needs.
