Autheo + Qtum
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. Qtum is Layer 1 Blockchain (Proof of Stake 3.0, Hybrid UTXO + EVM), The blockchain platform that unites Bitcoin's security with Ethereum's flexibility.. 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 | Qtum | Autheo |
|---|---|---|
| Layer Type | Layer 1 Blockchain (Proof of Stake 3.0, Hybrid UTXO + EVM) | Layer-0 OS + Integrated Layer-1 Blockchain |
| Consensus | Proof of Stake 3.0 (PoS 3.0). Block time: 32 seconds. Hybrid architecture: Bitcoin UTXO model for transaction accounting + Ethereum EVM via Account Abstraction Layer (AAL) for smart contracts. Online and offline staking supported; super stakers process delegated stake. | Proof of Autheo — hybrid PoA/PoS with deterministic rotation |
| Native Token | QTUM — Qtum Token | THEO coin (live: staking, transaction fees; compute and storage rolling out) |
| Post-Quantum Security | None — Qtum inherits Bitcoin's secp256k1 ECDSA. No post-quantum cryptography roadmap has been published. | In development — NIST Kyber, Dilithium, Falcon (not yet live) |
| Identity Layer | None — no protocol-level identity system. Qtum's hybrid architecture does not include a sovereign identity primitive. | In development — TheoID sovereign identity, post-quantum (rolling out) |
| DevHub/SDK | Qtum Core wallet, Qtum Electrum, EVM-compatible Solidity tooling, x86 VM (additional VM for C++, Rust, Python smart contracts). Qtum AI Router API for AI inference. No unified DevHub. | Yes, integrated full-stack DevHub + SDKs |
| Validator Model | Permissionless PoS: any QTUM holder can stake without minimum hardware requirements. Super stakers process delegated UTXOs (minimum 100 QTUM delegation, 2,000 confirmations required). As of January 2022, approximately 2,158 unique staker addresses and 25 active super stakers. No fixed validator cap — participation is open. Block halving schedule: next halving December 2025 (0.25 QTUM per block). | 399 sovereign validators (Core / Prime / Sovereign tiers) |

Frequently Asked Questions
What does Autheo bring to Qtum?
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. Qtum is Layer 1 Blockchain (Proof of Stake 3.0, Hybrid UTXO + EVM) focused on The blockchain platform that unites Bitcoin's security with Ethereum's flexibility.. 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 Qtum's foundation?
Where Qtum uses Proof of Stake 3.0 (PoS 3.0). Block time: 32 seconds. Hybrid architecture: Bitcoin UTXO model for transaction accounting + Ethereum EVM via Account Abstraction Layer (AAL) for smart contracts. Online and offline staking supported; super stakers process delegated stake. 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 Qtum?
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
“Qtum brings the best of both worlds together, since we can easily implement any Bitcoin Improvement Proposals (BIPs) to Qtum and Ethereum DAPPs can also be ported to Qtum.”

About this comparison
Qtum pioneered the hybrid UTXO + EVM architecture in 2017 and has maintained 100% uptime since mainnet launch. Its DGP mechanism allows on-chain parameter upgrades without hard forks. The new Qtum AI Router positions it for AI-compute use cases. Despite its technical achievements, Qtum's ~70 TPS throughput and aging ecosystem contrast with Autheo's Layer-0 OS architecture, which has post-quantum security on its roadmap.
