Autheo + Sei Network
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. Sei Network is Layer 1 EVM Blockchain (parallelized), The Fastest Layer 1 EVM Blockchain for High-Frequency Apps. 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 | Sei Network | Autheo |
|---|---|---|
| Layer Type | Layer 1 EVM Blockchain (parallelized) | Layer-0 OS + Integrated Layer-1 Blockchain |
| Consensus | Twin-Turbo Consensus (optimized Proof-of-Stake) | Proof of Autheo — hybrid PoA/PoS with deterministic rotation |
| Native Token | SEI | THEO coin (live: staking, transaction fees; compute and storage rolling out) |
| Post-Quantum Security | None mentioned | In development — NIST Kyber, Dilithium, Falcon (not yet live) |
| Identity Layer | None; no sovereign identity features | In development — TheoID sovereign identity, post-quantum (rolling out) |
| DevHub/SDK | create-sei CLI for bootstrapping, EVM-compatible SDKs, full Ethereum tooling support | Yes, integrated full-stack DevHub + SDKs |
| Validator Model | ~50 active validators|Minimum self-delegation 1 SEI, example create-validator uses 1M SEI|DPoS model, recommend delegating to 2-4 validators|High uptime required to avoid slashing | 399 sovereign validators (Core / Prime / Sovereign tiers) |
Why Builders Choose Autheo

Frequently Asked Questions
What does Autheo bring to Sei Network?
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. Sei Network is Layer 1 EVM Blockchain (parallelized) focused on The Fastest Layer 1 EVM Blockchain for High-Frequency Apps. 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 Sei Network's foundation?
Where Sei Network uses Twin-Turbo Consensus (optimized Proof-of-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 Sei Network?
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
“Sei Network is now the lowest-cost EVM-compatible stablecoin transfer chain, with an average of 200 stablecoin transfers costing only $0.0005. The upcoming Sei Giga will achieve a throughput of up to 200,000 TPS.”
— Jayendra Jog, Co-founder Sei Labs
“The SEI blockchain offers finality speeds under 400 milliseconds and can reach up to 250,000 transactions per second. It is one of the few Layer 1 blockchains that combines such high speed with EVM compatibility.”
— Analyst 'Not Telling'
