Autheo + Stellar
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. Stellar is Layer 1 Blockchain (Federated Byzantine Agreement), Where blockchain meets the real world. 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 | Stellar | Autheo |
|---|---|---|
| Layer Type | Layer 1 Blockchain (Federated Byzantine Agreement) | Layer-0 OS + Integrated Layer-1 Blockchain |
| Consensus | Stellar Consensus Protocol (SCP), a Federated Byzantine Agreement (FBA) system | Proof of Autheo — hybrid PoA/PoS with deterministic rotation |
| Native Token | Lumens (XLM) | THEO (utility: staking, compute, storage, AI inference, fees) |
| AI Integration | None / limited | In development — THEO AI native orchestration layer (rolling out on mainnet) |
| Post-Quantum Security | None (relies on ECDSA secp256k1, vulnerable to quantum attacks via Shor's algorithm) [BMIC Analysis](https://bmic.ai/us/compare/stellar/) | In development — NIST Kyber, Dilithium, Falcon (not yet live) |
| Identity Layer | None / basic account-based permissions, no sovereign identity or DID support | In development — TheoID sovereign identity, post-quantum (rolling out) |
| DevHub/SDK | Comprehensive SDKs and docs for building dApps, issuing assets, smart contracts (Soroban Rust SDK), tools like Horizon API, Hubble analytics; developer Discord and grants [Developers.Stellar.org](https://developers.stellar.org) | Yes, integrated full-stack DevHub + SDKs |
| Validator Model | Open participation; anyone can run a Stellar Core validator node; no staking or monetary rewards required; nodes define their own quorum sets of trusted nodes based on reputation; ~13 tier-1 validators targeted for resilience | 399 sovereign validators (Core / Prime / Sovereign tiers) |

Frequently Asked Questions
What does Autheo bring to Stellar?
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. Stellar is Layer 1 Blockchain (Federated Byzantine Agreement) focused on Where blockchain meets the real world. 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 Stellar's foundation?
Where Stellar uses Stellar Consensus Protocol (SCP), a Federated Byzantine Agreement (FBA) system consensus, Autheo uses Proof of Autheo, a hybrid PoA/PoS model with deterministic rotation. Autheo's roadmap also includes THEO AI, TheoID post-quantum identity, the Autheo Eigensphere Engine (AEE) runtime, 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 Stellar?
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 Stellar's AI capabilities?
Autheo is developing THEO AI as an orchestration layer for validator health, intelligent workflows, and AI inference. Stellar's AI integration is: None / limited. 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.

Expert Quotes
“The Stellar Consensus Protocol (SCP), a construction for FBA, provides a way to reach consensus without relying on a closed system to accurately record financial transactions.”
— Stellar Team
“We rigorously prove correct the Stellar Consensus Protocol (SCP), with our proof giving insights into the protocol structure and its use of lower-level abstractions.”
— Álvaro García-Pérez, Maria A. Schett
