Autheo + Stellar
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. Stellar is Layer 1 Blockchain (Federated Byzantine Agreement), Where blockchain meets the real world. Autheo extends any stack by delivering compute, storage, DevHub, and AI inference as one integrated platform.
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 Authority (PoA) with deterministic rotation |
| Native Token | Lumens (XLM) | THEO (utility: staking, compute, storage, AI inference, fees) |
| AI Integration | None / limited | Native: THEO AI built into the OS layer |
| Post-Quantum Security | None (relies on ECDSA secp256k1, vulnerable to quantum attacks via Shor's algorithm) [BMIC Analysis](https://bmic.ai/us/compare/stellar/) | Yes, NIST standards: Kyber, Dilithium, Falcon |
| Identity Layer | None / basic account-based permissions, no sovereign identity or DID support | Yes, AutheoID (post-quantum sovereign identity) |
| 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) |
Why Builders Choose Autheo
The advantages that matter for serious builders

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
