As of the evidence available for this overview, Ethereum is the only network in the allowed evidence set that can be confirmed here as using proof of stake; the available claims also describe Decred as a hybrid design, not a pure proof-of-stake example. These examples are not an exhaustive list of cryptocurrencies, and validator participation details should be checked against each network’s current protocol documentation.

What counts as a proof-of-stake network?

For this comparison, a network qualifies when its current consensus design uses stake as an economic basis for validator participation. “Validator” here refers to a protocol participant involved in the network’s consensus duties. This criterion is about the base network protocol, not whether an exchange, wallet, or other provider offers a product marketed as staking.

The distinction matters because a provider’s service may add custody, contract, operator, or product terms that are separate from the network’s own consensus rules. The evidence available for this article does not document particular provider offerings, eligibility thresholds, or service terms, so those cannot establish which networks belong in the protocol-level comparison.

Consensus designs can also change. The examples below should therefore be read in the context of the documented designs, not as a permanent classification of every network or token. The allowed evidence does not establish a review date for a broader survey of current networks, so this article does not claim to certify the status of networks outside the examples it can support.

Cryptocurrencies that use proof of stake: representative examples

Ethereum (ETH)

Ethereum’s proof-of-stake design uses ETH deposits as slashable economic collateral for validator participation. That describes a consensus role for the network’s native asset; it does not establish a particular reward rate or make every service involving ETH equivalent to direct protocol participation. Third-party staking products can add custody, smart-contract, operator, and legal risks beyond base-protocol staking.

Ethereum proof of stake combines validator attestations, a fork-choice rule, and checkpoint finality under protocol-defined supermajority conditions. In practical terms, the design has both a process for selecting or following a chain history and a protocol-defined way to distinguish finalized checkpoints. This is a description of Ethereum’s mechanism, not a claim that every transaction or application outcome is immediately final under all conditions.

Decred is useful as a boundary case rather than as a straightforward proof-of-stake entry. Its documented hybrid consensus combines proof-of-work block production with proof-of-stake ticket voting that approves blocks and participates in rule-change governance. Because block production and ticket voting have distinct roles, describing Decred simply as a pure proof-of-stake network would erase an important part of its design.

This distinction also illustrates why a network’s consensus label alone may not answer what its participants do. The relevant comparison is the actual allocation of protocol duties: Ethereum’s cited design uses stake-backed validators, while Decred’s cited design combines work-based block production with ticket-based voting.

The list is deliberately non-exhaustive. The evidence supplied for this article does not substantiate current consensus and validator details for additional networks, so naming them would go beyond the supported comparison. Inclusion here is descriptive, not an endorsement or investment judgment.

How validator participation differs across networks

For Ethereum, the evidence identifies ETH deposits as slashable collateral and validators as part of a design that uses attestations and checkpoint finality. This gives a concise view of the protocol-level role: stake is not merely an asset held by an application; it is tied to consensus participation under Ethereum’s rules. The evidence does not provide current eligibility thresholds, delegation mechanics, operator requirements, withdrawal rules, or reward amounts, so those details are not compared here.

For Decred, the cited participation model is different: ticket voting approves blocks and contributes to rule-change governance, while proof of work produces blocks. That means its proof-of-stake component should not be treated as identical to Ethereum’s validator model. The available evidence does not provide current ticket-acquisition rules, voting schedules, or financial terms, so those specifics remain outside this overview.

For any network, keep protocol participation separate from third-party arrangements. A service may provide an interface or pooled access, but its custody and operating model are not determined by the consensus mechanism alone. In Ethereum’s case, the evidence explicitly notes additional custody, smart-contract, operator, and legal risks for third-party staking products. It does not support a provider-by-provider comparison, nor does it establish equivalent conditions for other networks.

A useful technical comparison therefore asks which participant performs which consensus duty, what native asset is used as collateral or voting weight, and which rule determines acceptance or finality. Where the evidence does not answer those questions for a network, the responsible conclusion is that more protocol-specific research is needed—not that a familiar label implies the same operating model.

Consensus design is not the same as staking returns

Consensus architecture explains how a network organizes participation in agreement and chain history. It does not, by itself, establish a guaranteed return, an asset’s market value, or the terms of a third-party product. Ethereum’s slashable-collateral design indicates that participation carries protocol-defined risk; it is not a promise about rewards or a recommendation to participate.

Likewise, Decred’s ticket-voting role is a technical description of its hybrid consensus design, not an assessment of the financial results of holding or using DCR. This overview does not rank networks, estimate returns, or predict prices. No current reward, fee, or penalty figures are included because the allowed evidence does not establish them.

What to verify before relying on a network comparison

Before using a comparison for technical planning, check the network’s current protocol documentation for its active consensus design and any recent changes. Confirm the native asset’s specific protocol role, then verify validator or voter duties, eligibility, delegation, penalties, and withdrawal conditions directly where those topics matter. The available evidence supports only a subset of those details for the examples above.

Treat security questions separately from the consensus label. Ethereum’s documented operational risk categories include validator concentration, client concentration, key compromise, inactivity, slashing, censorship, and recovery under extreme conditions. These are possible risk areas in the cited Ethereum security analysis, not a claim that each occurs in every instance or that they characterize every proof-of-stake network.

Finally, verify whether a feature belongs to the base protocol or to a wallet, exchange, custodian, or other service. The distinction is essential when comparing validator participation: protocol rules describe what the network recognizes, while service terms govern the additional arrangement. If current documentation is unavailable for a network or feature, mark it as unverified rather than extending conclusions from Ethereum or Decred to the wider field.
