Autheo + ICON
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. ICON is Layer 1 Blockchain (Delegated Proof of Stake — DPoS) — NETWORK SHUTTING DOWN December 31, 2026, Go Cross-Chain with ICON — ICON's Cross-Chain Framework simplifies cross-chain development.. 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 | ICON | Autheo |
|---|---|---|
| Layer Type | Layer 1 Blockchain (Delegated Proof of Stake — DPoS) — NETWORK SHUTTING DOWN December 31, 2026 | Layer-0 OS + Integrated Layer-1 Blockchain |
| Consensus | Delegated Proof of Stake (DPoS) using Loop Fault Tolerance (LFT) consensus. 25 Main P-Reps and 75 Sub P-Reps (100 total) elected by ICX token holders via delegation. | Proof of Autheo — hybrid PoA/PoS with deterministic rotation |
| Native Token | ICX — ICON Token (migrating 1:1 to SODA token by December 31, 2026) | THEO coin (live: staking, transaction fees; compute and storage rolling out) |
| Post-Quantum Security | None — ICON uses standard ECDSA. Network shutting down December 31, 2026. | In development — NIST Kyber, Dilithium, Falcon (not yet live) |
| Identity Layer | None at protocol level. Cross-chain messaging (xCall) does not include an identity primitive. | In development — TheoID sovereign identity, post-quantum (rolling out) |
| DevHub/SDK | ICON Java SDK, Python SDK, JavaScript SDK, xCall standard interface. Tooling is mature for cross-chain messaging but no unified DevHub. Development activity is winding down ahead of December 2026 shutdown. | Yes, integrated full-stack DevHub + SDKs |
| Validator Model | 100 P-Reps total: 25 Main P-Reps (ranked 1–25 by delegated ICX, produce blocks) and 75 Sub P-Reps (ranked 26–100, receive rewards but do not produce blocks). Registration requires 2,000 ICX fee and 5% bond requirement. New P-Rep candidates can register permissionlessly. Network will cease operations December 31, 2026. | 399 sovereign validators (Core / Prime / Sovereign tiers) |
Why Builders Choose Autheo

Frequently Asked Questions
What does Autheo bring to ICON?
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. ICON is Layer 1 Blockchain (Delegated Proof of Stake — DPoS) — NETWORK SHUTTING DOWN December 31, 2026 focused on Go Cross-Chain with ICON — ICON's Cross-Chain Framework simplifies cross-chain development.. 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 ICON's foundation?
Where ICON uses Delegated Proof of Stake (DPoS) using Loop Fault Tolerance (LFT) consensus. 25 Main P-Reps and 75 Sub P-Reps (100 total) elected by ICX token holders via delegation. 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 ICON?
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 vision for BTP is to be prepared for anything. 3 years ago, nobody imagined what interoperability would be used for, now there's a focus on DeFi. What's next? We don't need an answer, we just need a flexible, secure and decentralized interoperability solution, and that's what BTP is.”

About this comparison
ICON was a pioneering interoperability Layer-1 that connected 17+ blockchain networks via xCall General Message Passing. Its cross-chain messaging standard influenced subsequent protocols. However, ICON Network is permanently shutting down December 31, 2026, with ICX migrating 1:1 to SODA on SODAX. This makes ICON a legacy reference point — not a viable building target — and underscores Autheo's architectural durability as a purpose-built Layer-0 OS with long-term infrastructure mandates.
