Autheo + Ethereum Classic
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 Classic is Layer 1 Blockchain (Proof-of-Work), Proof-of-Work Smart Contracts | Code is Law. 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 Classic | Autheo |
|---|---|---|
| Layer Type | Layer 1 Blockchain (Proof-of-Work) | Layer-0 OS + Integrated Layer-1 Blockchain |
| Consensus | ETChash Proof-of-Work (modified Ethash) | Proof of Autheo — hybrid PoA/PoS with deterministic rotation |
| Native Token | Ether Classic (ETC) | THEO coin (live: staking, transaction fees; compute and storage rolling out) |
| Post-Quantum Security | None (ECDSA vulnerable to quantum attacks) | In development — NIST Kyber, Dilithium, Falcon (not yet live) |
| Identity Layer | None (standard account model, no native sovereign identity) | In development — TheoID sovereign identity, post-quantum (rolling out) |
| DevHub/SDK | EVM-compatible; Core-Geth client, ECIPs for improvements; Standard Solidity tools | Yes, integrated full-stack DevHub + SDKs |
| Validator Model | Miners using GPU/ASIC hardware with ETChash algorithm; Node operators run Core-Geth client (low requirements: regular PC); ~446 nodes worldwide | 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 Classic?
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 Classic is Layer 1 Blockchain (Proof-of-Work) focused on Proof-of-Work Smart Contracts | Code is Law. 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 Classic's foundation?
Where Ethereum Classic uses ETChash Proof-of-Work (modified Ethash) 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 Classic?
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.

Expert Quotes
“I was there when we made the choice to defend immutability... 'code is law' was not just a slogan it was a moral commitment to the permanence of truth.”
— Cody Burns
“Code is law on the blockchain. All executions are final, all transactions are immutable.”
— Vitalik Buterin (early context)

About this comparison
Ethereum Classic is highly relevant as the sole continuation of the original Ethereum blockchain, embodying 'Code is Law' after the 2016 DAO fork. As the premier PoW smart contract platform post-Ethereum's PoS shift, it provides unmatched immutability and censorship resistance, making it a key benchmark for next-gen chains integrating AI, quantum security, and identity.
