Autheo + Stellar
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. Stellar is Layer 1 Blockchain (Federated Byzantine Agreement), Where blockchain meets the real world. 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 | 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 coin (live: staking, transaction fees; compute and storage rolling out) |
| 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) |
Why Builders Choose Autheo
The advantages that matter for serious builders

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 Stellar?
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. 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, 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 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 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.
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
“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

About this comparison
Stellar is an established Layer 1 blockchain with a top-20 market cap, known for efficient cross-border payments and serving major fintechs and institutions; it is a relevant comparison as a payments-focused protocol without native identity or post-quantum layers, both of which are on Autheo's roadmap.
