What consensus mechanism does Autheo use?

Autheo uses Proof of Autheo, a hybrid consensus model that combines licensed validator eligibility (similar to Proof-of-Authority) with stake-weighted block production (Proof-of-Stake). The underlying consensus engine is Cosmos SDK and Tendermint core BFT.

What is the difference between Proof of Autheo and standard Proof of Authority?

Standard Proof of Authority (PoA) relies solely on trusted, pre-approved identities to produce blocks — there is no staking or economic commitment required. Proof of Autheo adds a second gate: validators must also meet a staking or bonding threshold. Once both gates are satisfied, the active set operates on a stake-weighted model, not a pure identity model. This means Proof of Autheo has stronger economic security than traditional PoA.

Do I need to stake to run an Autheo validator?

Yes. Running a validator on Autheo requires two things: holding an Autheo NFT License (the eligibility gate) and meeting the required staking or bonding threshold (the commitment gate). Both are required. Holding the license alone is not sufficient.

What is Tendermint BFT and why does Autheo use it?

Tendermint core BFT is a Byzantine fault-tolerant consensus engine that provides fast, single-block finality. It can tolerate up to one-third of validators behaving maliciously without compromising the network. Autheo builds on Tendermint because it is one of the most extensively audited and production-proven consensus engines in the blockchain ecosystem, used by Cosmos, Osmosis, and dozens of other chains.

How many validators does Autheo support?

Autheo has 399 structurally scarce validator positions. The combination of NFT License eligibility and staking requirements means this set is intentionally limited and difficult to replicate, contributing to the long-term security and economic value of the network.

什么是 Proof of Autheo？

Autheo 运行在 Proof of Autheo 上，这是一种混合共识模型，将持牌 Validator 资格与质押加权出块相结合。Validator 必须持有 Autheo NFT 许可证并满足质押阈值。底层框架基于 Cosmos SDK 和 Tendermint core BFT 构建。

一旦满足两个要求，活跃验证者集将使用标准的权益加权权益证明模型运行，验证者按其权益比例获得奖励并生产区块。底层框架建立在 Cosmos SDK 和 CometBFT 之上，在超过 200 个在运行链上提供拜占庭容错终局性和经过验证的生产级安全性。

The Dual Gate Model

Every validator must pass two independent gates before participating in consensus. Both are required — neither alone is sufficient.

Gate 1 — Eligibility

NFT License

Validators must hold a valid Autheo NFT License to join the active set. This gate mirrors Proof-of-Authority permissioning — ensuring every operator is vetted, identifiable, and accountable before they can produce or finalize a block. No license, no entry.

Gate 2 — Commitment

Staking & Bonding

Validators must also meet the required staking or bonding threshold. Economic skin in the game ensures validators have a financial incentive to behave honestly. Slashing mechanisms apply to misbehavior, making attacks costly.

The result

Once both gates are satisfied, the active validator set operates on a stake-weighted Proof-of-Stake model. Block production and rewards are proportional to stake — not identity alone. This combines the accountability of PoA with the economic alignment of PoS.

Under the Hood

Proof of Autheo is implemented on top of proven, battle-tested infrastructure used by dozens of production blockchains.

Cosmos SDK

The Cosmos SDK provides the modular application framework that powers Autheo's chain logic, staking module, governance structures, and IBC interoperability. It is one of the most widely audited blockchain frameworks in production.

CometBFT

Tendermint core BFT handles consensus management: proposing blocks, collecting validator votes, and finalizing state. It provides Byzantine fault tolerance up to one-third of validators behaving maliciously, with fast finality in a single block round.

Autheo's NFT License gate and staking requirements are layered on top of Tendermint's validator set management — they determine who is eligible to enter the validator set, while Tendermint handles how consensus is reached once the set is established.

Why This Design?

Every architectural decision in Proof of Autheo was made to balance security, economic alignment, and validator scarcity.

Identity-Level Security

The NFT License gate means every validator is known and accountable before they join. There's no anonymous actor producing blocks — a meaningful security improvement over permissionless PoS.

Economic Alignment

The staking gate ensures validators have real financial exposure. Honest participation is rewarded; misbehavior is penalized via slashing. Incentives are aligned with network health.

Structural Scarcity

399 validator positions are available — no more. The combination of NFT License requirements and staking thresholds creates a genuinely scarce, high-integrity validator set that is difficult to replicate.
