Autheo + Ethereum
Autheo is a Layer-0 Operating System with an integrated Layer-1 blockchain and a roadmap that brings identity, compute, storage, and developer tooling into one interoperable environment. Ethereum is Layer 1 (+ L2 ecosystem), The home for digital money, global apps, and more. Staking and transaction fees are live today; compute, storage, TheoID, and post-quantum cryptography are rolling out on mainnet.
Understand Autheo first
Autheo is a Layer-0 Operating System with an integrated Layer-1 blockchain that unifies identity, compute, storage, developer tooling, and AI capabilities in one interoperable environment.
This comparison page shows how Autheo complements other platforms in practice, but the best place to understand Autheo itself is through the core platform and architecture pages.
Feature Overview
A full feature breakdown
| Feature | Ethereum | Autheo |
|---|---|---|
| Layer Type | Layer 1 (+ L2 ecosystem) | Layer-0 OS + Integrated Layer-1 Blockchain |
| Consensus | Proof of Stake (post-Merge) | Proof of Autheo — hybrid PoA/PoS with deterministic rotation |
| Native Token | ETH | THEO coin (live: staking, transaction fees; compute and storage rolling out) |
| Post-Quantum Security | Not specified | In development — NIST Kyber, Dilithium, Falcon (not yet live) |
| Identity Layer | Not specified | In development — TheoID sovereign identity, post-quantum (rolling out) |
| DevHub/SDK | Not specified | Yes, integrated full-stack DevHub + SDKs |
| Validator Model | Validators require 32 ETH (~$60K+) minimum stake; 500K+ validators | 399 sovereign validators (Core / Prime / Sovereign tiers) |
Why Builders Choose Autheo
The advantages that matter for serious builders
Unified Layer-0 OS with an integrated, EVM-compatible Layer-1 (live since May 2026)
Proof of Autheo consensus: hybrid PoA/PoS on Cosmos SDK and Tendermint BFT
Integrated DevHub for deployment
TheoID sovereign identity layer (rolling out)
Post-quantum cryptography roadmap (Kyber, Dilithium, Falcon; not yet live)
Single validator node designed for full-stack participation as layers roll out
Frequently Asked Questions
What does Autheo bring to Ethereum?
Autheo is a Layer-0 Operating System with an integrated Layer-1 blockchain a full DevHub, and a roadmap for post-quantum cryptography and TheoID sovereign identity. Ethereum is Layer 1 (+ L2 ecosystem) focused on The home for digital money, global apps, and more. Staking and transaction fees are live today; compute, storage, sovereign identity, and post-quantum capabilities are rolling out over the coming months.
How does Autheo build on Ethereum's foundation?
Where Ethereum uses Proof of Stake (post-Merge) consensus, Autheo uses Proof of Autheo, a hybrid PoA/PoS model with deterministic rotation. Autheo Chain is EVM-compatible for Solidity smart contracts and built on the Cosmos SDK, and Autheo pairs it with a fully integrated DevHub, with TheoID post-quantum identity on its roadmap as part of a single, cohesive platform. TheoID is still rolling out on mainnet.
What security does Autheo add beyond Ethereum?
Autheo is building post-quantum cryptography around NIST-standard algorithms: Kyber (key encapsulation), Dilithium (signatures), and Falcon (signatures). The planned implementation is designed to secure validator identity and communications against both classical and quantum attacks as it rolls out; it is not yet live. Autheo has also partnered with Halborn, an industry leader with 2,500+ blockchain security audits, for ongoing security review.
Who benefits most from building on Autheo?
Builders evaluating a complete, integrated roadmap for blockchain, compute, storage, identity, and developer tooling. Staking and transaction fees are live today; compute, storage, TheoID, and post-quantum cryptography are rolling out over the coming months.
