Autheo + Stacks
Autheo is a Layer-0 Operating System with an integrated Layer-1 blockchain and a roadmap that brings identity, compute, storage, developer tooling, and AI capabilities into one interoperable environment. Stacks is Layer 2 on Bitcoin, The Leading Bitcoin L2 for Smart Contracts, Apps, DeFi. Staking and transaction fees are live today; compute, storage, AI inference, TheoID, THEO AI, 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 | Stacks | Autheo |
|---|---|---|
| Layer Type | Layer 2 on Bitcoin | Layer-0 OS + Integrated Layer-1 Blockchain |
| Consensus | Proof of Transfer (PoX) | Proof of Autheo — hybrid PoA/PoS with deterministic rotation |
| Native Token | STX | THEO (utility: staking, compute, storage, AI inference, fees) |
| AI Integration | None native; minor community AI+Bitcoin working group | In development — THEO AI native orchestration layer (rolling out on mainnet) |
| Post-Quantum Security | None mentioned | In development — NIST Kyber, Dilithium, Falcon (not yet live) |
| Identity Layer | None native | In development — TheoID sovereign identity, post-quantum (rolling out) |
| DevHub/SDK | Clarity language, Hiro developer tools, Stacks API, docs and tutorials at docs.stacks.co | Yes, integrated full-stack DevHub + SDKs |
| Validator Model | Miners spend BTC to mine blocks rewarded in STX; Stackers lock STX to validate/sign blocks (70% quorum needed), earn BTC; no fixed validator count, permissionless; dynamic min stack for solo stacking | 399 sovereign validators (Core / Prime / Sovereign tiers) |

Frequently Asked Questions
What does Autheo bring to Stacks?
Autheo is a Layer-0 Operating System with an integrated Layer-1 blockchain and a roadmap for THEO AI, post-quantum cryptography, TheoID sovereign identity, and a full DevHub. Stacks is Layer 2 on Bitcoin focused on The Leading Bitcoin L2 for Smart Contracts, Apps, DeFi. Staking and transaction fees are live today; compute, storage, AI inference, sovereign identity, and post-quantum capabilities are rolling out over the coming months.
How does Autheo build on Stacks's foundation?
Where Stacks uses Proof of Transfer (PoX) 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's roadmap also includes THEO AI, TheoID post-quantum identity, and a fully integrated DevHub as part of a single, cohesive platform. THEO AI and TheoID are still rolling out on mainnet.
What security does Autheo add beyond Stacks?
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.
How does Autheo's native AI compare to Stacks's AI capabilities?
Autheo is developing THEO AI as an orchestration layer for validator health, intelligent workflows, and AI inference. Stacks's AI integration is: None native; minor community AI+Bitcoin working group. THEO AI and AI inference are rolling out on mainnet and are not yet live.
Who benefits most from building on Autheo?
Builders evaluating a complete, integrated roadmap for blockchain, compute, storage, AI, identity, and developer tooling. Staking and transaction fees are live today; compute, storage, AI inference, TheoID, THEO AI, and post-quantum cryptography are rolling out over the coming months.
